BMW 5 Series

A unique blend of style, space, luxury and sportiness.
Woodcliff Lake, NJ - May 23 2009... The BMW 5 Series Gran Turismo adds new facets to BMW's Ultimate Driving Machine tradition and refines the concept of first-class travel. For the first time, attributes of an elegant sedan, a contemporary Sports Activity Vehicle and a classic Gran Turismo are masterfully melded into a single, harmonious vehicle concept.

The traditional European term Gran Turismo (Grand Touring) was first applied by Italian carmakers in the 1950s when they combined the performance, handling, and style of a 2-seat sport car with luxurious amenities and luggage room for each occupant. BMW’s new Gran Turismo nurtures this tradition in its own contemporary way, providing exceptional space, style, luxury, and comfort for four passengers1, plus the performance and driving pleasure of a BMW.

It does so with 21st-century performance. BMW’s wide-ranging EfficientDynamics initiative endows this new automobile with an outstanding balance between performance and efficiency. Thanks to its innovative twin turbo V-8 engine and 8-speed automatic transmission, the 550i Gran Turismo can accelerate from rest to 60 mph in just 5.4 seconds, yet delivers remarkable fuel efficiency in everyday driving.

Design: Abundant sportiness, elegance, luxury and versatility.
• Typical BMW proportions communicate dynamic character and sportiness.
• Long wheelbase and graceful, coupe-like roofline.
• An interior with contemporary design, generous dimensions and premium materials.

The BMW 5 Series Gran Turismo radiates a unique blend of sportiness and stylish presence. Typical BMW proportions, four doors with frameless windows, and a coupe-like roofline combine into a harmonious, highly distinctive silhouette that visually represents this vehicle’s unusual blend of capabilities.

This vehicle’s visual presence is a captivating fusion of established BMW identity and new elements. Its elongated hood and long 120.7-inch wheelbase coalesce with a “greenhouse” set well aft and a fastback roofline into a profile that’s immediately recognizable as a BMW, yet at the same time communicates a new vehicle concept. From the first glance, it’s clear that this is an exceptionally roomy conveyance, yet also a highly dynamic one.

Inside the 5 Series Gran Turismo, users find generous dimensions, inspired contemporary design, and individualized luxury. Sweeping contours – such as those of the interior door panels – combine with elegant and premium-quality materials to create an ambiance that’s equally satisfying to front and rear occupants.

At the front: thoroughly modern, traditionally BMW.
The Gran Turismo’s frontal aspect has a marked forward thrust, with its traditional BMW “kidney grille” leaning slightly forward and emphasized by its separation from the flanking (also traditional) four round headlights.

BMW’s signature corona rings have taken on several functions: as parking lights, as an identifying element when the headlights are on, and as Daytime Running Lamps – this last with 100% of their lighting power, the other functions with just 10%. For the first time, on the Gran Turismo they employ LED technology.

In profile: frameless door windows and a new form of “Hofmeister Kink.”

The 5 Series Gran Turismo is also the first 4-door BMW to have frameless door windows – a feature BMW usually reserves for Coupes and Convertibles. These give an “open” look to side and angled views of the vehicle.

Over the years, another window detail has become a tradition: BMW’s so-called “Hofmeister Kink,” named after Wilhelm Hofmeister, who headed BMW design when this shape first appeared. On the Gran Turismo, it appears in “6-window” (3 windows per side) form in the rear quarter windows aft of the rear doors, framed in matte black plus chrome or optional high-gloss Shadowline black trim.

At the rear: aesthetically and functionally distinctive
Another BMW design tradition, in evidence since a new-generation 7 Series was introduced for 1988 is the freely interpreted L-shape of the rear lighting clusters. On the 5 Series Gran Turismo this theme is retained but newly interpreted LED lighting wraps far around the body sides and provides yet another recognizable BMW design cue. Together, these elements reinforce the impression of the Gran Turismo’s wide stance, which is further enhanced by strong horizontal lines spanning the bi-modal trunk and likewise tying in with character lines of the side profile.

Function, more even than the handsome aesthetics, is the main attraction of the 5 Series Gran Turismo’s interesting rear view. Below the rear window is a conventional, though shorter-than-usual, sedan trunklid that opens separately to reveal a fully enclosed trunk – sealed off from the passenger cabin by a movable partition that renders the interior as quiet as that of a sedan.

To take full advantage of the 5 Series Gran Turismo’s great cargo capacity, though, the liftgate – including the lower trunklid, rear window and an upper section reaching a few inches above the window – can also be opened. There are two releases, one for the trunklid alone, the other for the entire liftgate including trunklid.

Interior design: spacious luxury at its finest.
The BMW 5 Series Gran Turismo interior combines space, luxury and stylish materials to create a premium ambiance. In the rear seats as well as up front, there’s a sense of generous space and comprehensive amenities, promoting relaxed and accommodating travel.

The outstanding feeling – and reality – of spaciousness is enhanced by design and materials. Dash and instrument panel lines are decidedly horizontal; door panels sweep dramatically and harmoniously from front to rear. Thanks to their frameless design, the door windows are larger than they would be with frames, adding to the openness of the remarkable cabin; the dual-panel panoramic moonroof, standard on the U.S. model, also contributes to these effects.

In standard form, the rear seating accommodates three passengers, with a 40-20-40 split of the backrest allowing for selective fold-down. In addition, the entire seat cushion can be adjusted 3.9-in. fore and aft and the individual backrest sections can be adjusted over a range of 15?-33?. Yet there’s more here than just adjustability: there’s also outstanding personal space, with legroom on the scale of BMW’s 7 Series Sedan and headroom comparable to the BMW X5 Sports Activity Vehicle. Indeed, first-class comfort is afforded all occupants of the Gran Turismo.

Optional as part of the Luxury Rear Seating Package are individual, multi-adjustable power seats, separated by a center console with cupholders and a storage compartment; here the backrest range is 15?-40? and even the fold-down function is powered. In addition to the power adjustments, a further attraction of this configuration is that it transforms the cabin into a sportier, strictly 4-seater configuration that some customers will prefer for its aesthetics, intimacy and greater luxury.

Accompanying the variable seating accommodations is variable cargo capacity, ranging from an already generous 15.5 cu ft. in the sedan-style enclosed trunk to fully 60.0 cu ft. (DIN rating) with folded rear seats and SAV-style long cargo floor. A variable partition between the trunk and passenger compartments provides occupants with sedan-type climate and noise insulation even when the trunk is being loaded, yet moves with the seats when they are adjusted and folds flat when the greatest capacity is needed.

Optimum outward view for the driver.
Thanks to its ideal front seat height, the BMW 5 Series Gran Turismo driver and front passenger enjoy excellent outward visibility. For comparison, the Gran Turismo’s standard seat height from the ground is 22.6 in., vs. the previous-generation 7 Series’ 20.8 and the X3’s 26.6. In other words, the Gran Turismo seat is higher than the typical BMW sedan for easier access and an enhanced outward view, yet not so high as to require “climbing up.” Rear seating is also slightly higher than in BMW Sedan models.

As in all BMWs, thoughtfully researched ergonomics allow for optimum operation of driving controls and other functions. All displays, knobs and buttons serving comfort functions are situated centrally for use by the driver and front passengers; controls for the driver’s use only are to the left of the steering wheel, on or near the steering wheel, or on the front center console. The steering wheel has power tilt and telescopic adjustment and tilt-away for exit and entry; and of course both front seats come standard with 10-way power adjustment including head-restraint height.

Instrument panel in Black Panel technology.
Like so many aspects of the 5 Series Gran Turismo, its instrument cluster combines BMW tradition with advanced, beautiful new executions. Here the entire cluster is in a high-resolution Black Panel display, in which four classic circular instruments are most prominent; other driving-relevant displays and readouts – including Navigation if present, vehicle-monitoring functions, upcoming service requirements and other information – also appear here in their various (and function-related) graphic forms. Climate-control settings and controls are located in a second Black Panel display in the center console stack.

So it is that the advantages of mechanical and electronic displays are ideally combined with eye-catching visual and graphic effects. As the user enters the vehicle, the circular instruments’ “chrome rings,” until now open at the bottom, close and become brighter. Once the ignition is activated (by pressing the Start/Stop button), the numerals plus all other displays and warnings illuminate. As the engine starts, functions that have been previously activated by the driver are then revealed as well.

4th-generation iDrive: more user-friendly, more intuitive, faster.
With the 5 Series Gran Turismo, BMW’s all-new, 4th generation iDrive system appears in two versions: with 7.0-in. dimensions and 800 x 480-pixel resolution in standard form, or with the optional Navigation system, in a dazzling 10.2-in., 1280 x 480-pixel version with a wider range of features and functions as in the new BMW 7 Series. Displays are transreflective so that light from the sun actually enhances the images on the screen.

The instrument cluster interacts in new ways with the iDrive control display and the available Head-up Display. According to selected function, users can call up phone numbers or radio stations via the steering-wheel controls. The cluster display also augments iDrive’s optional Navigation display with road-realistic directional instructions, helping the driver with to change lanes or turn at a complicated intersection. If the optional Head-up Display is activated, the relevant directions appear there.

Materials and colors: enhancing the elegance.
The choices of colors and materials further enhance the impression of personal luxury and the interior’s interplay of lines and surfaces. For the dash’s finely grained upper section, there are two colors depending upon the chosen interior color. Dakota leather is standard, and available in six color schemes of which three are new; BMW’s luxurious Nappa leather is optional, and available in three color schemes.

Dark Burl Ash wood trim interior trim is standard, appearing in sweeping expanses on the dash, doors and front center console; Ash Anthracite (gray tone) and another distinctive wood called Fineline Matte are optional. As a special visual and tactile treat, ceramic trim is optional for the shift knob, iDrive controller surround, and audio and climate controls.

5. Powertrain.
The essence of EfficientDynamics.
• Twin turbo V-8 engine delivers 400 hp and 5.4 second 0-60-mph time, plus silken refinement and impressive fuel efficiency considering the performance.
• New 8-speed automatic transmission contributes to performance and fuel efficiency.

With the 5 Series Gran Turismo, BMW lays the cornerstone for a new type of automobile – while also demonstrating BMW’s traditional mastery of an all-important aspect of automotive performance: the powertrain.

The Gran Turismo debut model is the 550i, powered by BMW’s stunning 4.4-liter, 400-hp twin turbocharged V-8 engine. Compared to BMW’s normally aspirated V-8, displacement is reduced from 4.8 to 4.4 liters, and incorporates twin turbochargers and High Precision direct injection. In quantitative terms, the new engine delivers 400 hp and does so over a range from 5500 to 6400 rpm. Maximum torque is 450 lb-ft., and available over the extremely broad range of 1800 to 4500 rpm. The result is greater power and torque delivered over a wide range of operating conditions with greater fuel efficiency. Aside from the dramatic thrust that drivers will notice subjectively, the objective data are dramatic too: 0-60 mph in just 5.4 seconds and a top speed when equipped with the Sport Package of 150 mph. For models equipped with all-season tires the maximum speed is limited to 130 mph.

Through its unique reverse-flow layout, the 550i’s V-8 engine is able to achieve even higher performance without correspondingly higher fuel consumption. In technical terms, the approach involves some very new design details. For the first time, twin turbochargers and the exhaust-cleansing catalytic converters are placed between the V-8’s two cylinder banks. In turn, this required the exhaust camshafts and valves to be inboard so that the path from cylinders to turbochargers (which are driven by exhaust gas) would be efficiently short. A key benefit of this layout is a more compact engine package. This is the reverse of a traditional V-8 layout, and opens a new era of V-8 engine development potential.

A key feature of the engine is BMW’s High Precision direct injection. Positioned centrally in the combustion chambers for optimum combustion, the injectors deliver fuel at very high pressures. To meet BMW’s ambitious performance/efficiency/emissions goals with the necessary long-term durability, a “stack” of piezo crystals reacts lightning-fast to impulses from the Digital Motor Electronics, governing the injector needle’s opening stroke and duration for ultra-precise control. This contributes 2-3% fuel savings and reduces emissions by 20%. The engine (also as featured in the new 7 Series and BMW X6) meets U.S. ULEV II (Ultra Low Emissions Vehicle) limits. And High Precision direct injection contributes to the acoustic presence of the engine.

Playing a supporting role: innovative new 8-speed automatic transmission.
The 5 Series Gran Turismo’s innovative character is further supported by its all-new 8-speed automatic transmission, which brings smooth shifting, sportiness and efficiency to a new level of perfection. Compared to the exemplary 6-speed automatic offered in most current BMW models, the 8-speed’s “taller” cruising gears make a significant contribution to reduced fuel consumption and carbon-dioxide emissions as well as quietness. And its wider spread of ratios from lowest to highest gear enhances acceleration and response across the range of driving speeds.

Technically speaking, this new automatic’s attributes have been achieved via an innovative concept that provides the two additional ratios (7 and 8) with no increase in bulk or weight. In an arrangement not heretofore employed in an 8-speed automatic, four planetary gearsets and five clutch packs are controlled in a way that no more than two of the five clutch packs are freewheeling at any given time. The modest increase in the number of mechanical elements allows the new transmission to achieve unusually high efficiency: the so-called “gearing efficiency” is higher than 98% in all eight gears. In 6th gear, it’s highest of all because that is direct drive, with no gearing at all. Combine this with reduced friction and the ability to keep the torque converter “locked up” more of the total driving time, and you have a transmission that is very much a part of the 5 Series Gran Turismo’s overall efficiency concept.

Two additional gears mean threefold progress: quicker shifts, greater smoothness, enhanced efficiency.
The wider spread of ratios allows the engine to run at lower speeds, mainly in the “tallest” gear, 8th. Yet even with this wider spread, the steps between adjacent gears are reduced; in turn this means a stronger, smoother flow of power during acceleration.

And for the same reason, faster shifts are a further benefit because only one clutch pack is disengaged to shift up or down by one or two gears. On the other hand, downshifting more than two gears is accomplished as a direct shift. For example, a downshift from 8th to 2nd gear is made with only one clutch pack disengagement, and thus occurs without stepping down through the intermediate gears. Thus at one instant the driver can be enjoying the quiet, fuel-efficient low rpm of 8th gear, and in the next instant getting maximum acceleration.

Brake Energy Regeneration: an energy-saving innovation.
For the first time in a U.S. BMW model, the new 5 Series Gran Turismo is equipped with BMW’s Brake Energy Regeneration system.

To save energy and reduce the vehicle’s fuel consumption, this system controls the times at which the alternator charges the battery. Conventionally, a car’s alternator runs continuously and thus charging is always available to the battery; in the Gran Turismo, it charges only when the vehicle is decelerating or braking; otherwise, it freewheels, drawing virtually no power from the engine. An electronically controlled clutch, somewhat similar to that used with the air-conditioning compressor, is added to engage and disengage the alternator.

Accommodating the less frequent charging is a special, more powerful battery that can satisfy a contemporary vehicle’s high electrical demands without access to continuous charging. The battery uses a technology called “glass mat,” in which its internal plates are separated with saturated absorbent glass-boron silicate rather than the usual liquid electrolyte. This construction sharply reduces the battery’s conversion of charging energy to heat, and can provide the necessary electrical power for longer periods between charges.

6. Chassis engineering.
State-of-the-art BMW capabilities, adjustable to suit personal tastes.

• Comfort, dynamics and precision – all promoted by the new combination of multi-link front and rear suspension systems.
• Driving Dynamics Control and self-leveling rear air suspension – standard.
• Adaptive Drive: optional Active Roll Stabilization and Dynamic Damping Control further refine the Gran Turismo’s amazing blend of handling dynamics and riding comfort.

True to BMW tradition, the new Gran Turismo exploits the creation of a new vehicle generation to advance the art of chassis technology and engineering. Improving both driving dynamics and riding comfort are always the core goals of the transition to a new BMW generation, and in these regards the Gran Turismo upholds the tradition brilliantly.

Just as the new engine combines sporting performance with luxurious refinement, all-around new suspension technology endows the Gran Turismo with uniquely agile handling for a luxury automobile, yet also an exceptional level of riding comfort. Beyond these “basics,” this new vehicle allows the driver to decide at any time what priority to assign to either of these attributes via Driving Dynamics Control.

Front suspension: a new multi-link system.
Until recently, all BMW front suspension systems since 1965 2 had been of the strut type, in which a long, essentially vertical strut carries the shock absorber and participates in the suspension geometry – that is, along with the lower arms it helps determine the angles wheels take as they move up and down. With the double-pivot lower arms of most current BMW Series, the strut concept has been taken to a high level of sophistication in handling, straight-ahead stability and riding comfort. However, time and progress never stop; BMW conceptualists and engineers continually seek even better solutions. So it was that when the 2nd-generation X5 made its debut in ’07, BMW introduced a type of front suspension that achieves even better results, particularly in a large, relatively heavy and very powerful vehicle.

Now this system has made its debut in the automobile side of BMW’s vehicle line, first in the new 7 Series for ’09 and now in the 5 Series Gran Turismo for 2010. In place of the strut, this new system has an upper lateral A-arm. The double-pivot lower arms are retained, so that on each side there are three links or arms. While the two lower arms preserve the double-pivot strut system’s advantages, the new upper arm facilitates the system’s handling and riding comfort by relieving the strut of its geometric duties.

Among the strengths of the double-pivot system are:
• Small positive steering offset, for best steering feel and control under all road conditions. Though the two lower arms don’t actually intersect, if you visually extend their axes to a point where they would intersect, you find a “virtual pivot point” that is ideal for achieving this result. Steering offset is the “lever arm” through which road forces act on the suspension system.
• Large steering caster, for outstanding stability in straight-line driving and excellent steering return action coming out of curves.
• Space for large brakes, allowed by the arrangement of the two lower arms.

The 5 Series Gran Turismo’s multi-link configuration adds further virtues:
• Reduced friction because the shock absorber (which remains essentially concentric with the spring, as it was with the strut system) no longer helps locate the wheel, and is thus no longer subject to lateral forces. This allows the shock absorbers to damp the wheels’ up-and-down motions in a more efficient, targeted way, enhancing both ride and handling (particularly on uneven road surfaces).
• Anti-roll (stabilizer) bar attached to wheel carrier. This arrangement, which differs from many competitors’ attachment to a suspension link, applies the wheel’s entire vertical movement (up or down) to the anti-roll bar, thus allowing thinner bars to be used. Effective control of body roll (lean) and weight savings are thus achieved.
• Greater freedom to optimize both suspension geometry and shock-absorber action.

In keeping with another BMW tradition – aluminum suspension components to reduce unsprung weight and thus improve road adhesion and riding comfort – most major elements of the new front suspension are aluminum:
• Upper and lower lateral links (1 upper, 2 lower per side)
• Steering knuckle/vertical link (1 per side).

Further reducing unsprung weight are the front brake calipers, which are of composite aluminum/cast-iron construction. The suspension subframe, which is sprung weight but important in terms of front/rear weight distribution and total vehicle weight, is also of aluminum. Yet more advantages are found in certain details:
• The trailing (forward) lower arm has a rubber/hydraulic cushion, which provides the most effective “compliance” for reducing road shock.
• The transverse (rearward) lower arm is cushioned by a finely tuned rubber element that fosters direct and precise response to the steering wheel in curves and corners.

Rear suspension.
The rear suspension, too, is a significant evolution for BMW. Like the front suspension, it is a multi-link system; BMW calls it the Integral system for its small, essentially vertical Integral Link connecting the upper and lower lateral control planes.
The Integral suspension concept has been in use for some years in BMW automobiles, appearing currently in the 5 and 6 Series in 4-link form. With one additional link per side, the Integral V (5-link) system moves one step closer to perfection in its combination of handling response, road adhesion and riding comfort. Here too, most major elements are aluminum, and the rear suspension subframe is also of aluminum.

This complex multi-link system controls rear-wheel geometry very precisely, minimizing unwanted effects under load changes (such as lifting off the accelerator while cornering, or hard acceleration and braking) and achieving a comfortable, supple ride. In the new 5 Series Gran Turismo, it adds yet another capability via optional Integral Active Steering as introduced on the 2009 BMW 7 Series.

At the front wheels, Integral Active Steering electronically varies the steering ratio (the number of degrees the steering wheel must be turned to achieve a 1º steering angle at the front wheels) on the basis of vehicle speed and other driving conditions. This reduces the steering-wheel movements required for parking maneuvers, U-turns and sharp corners.

Also with Integral Active Steering, the rear wheels are steered up to a maximum of 3? via a servo motor acting on track rods. At low speeds, they are steered oppositely to the front wheels, reducing the turning circle by more than 2 feet. At higher speeds, the rear wheels steer in the same direction as the fronts, enhancing stability. Additionally, the rear-seat passenger comfort is improved thanks to reduced lateral forces in highway lane-change conditions.

Appropriately for a vehicle designed to carry the cargo of active lifestyles, the 5 Series Gran Turismo comes standard with self-leveling rear suspension. Self-leveling is achieved by an electrically powered air compressor and ride-height sensors that recognize changes in vehicle loading. Whenever the sensors detect a longer-term change in ride height at the rear (as when a full passenger load is aboard or heavy loads are carried in the trunk), the air pressure is increased to bring the vehicle back to its normal attitude. Additionally, when one of the rear tires suffers pressure loss, the air springs act to equalize the ride height on the two sides.

Newly evolved, new name: Dynamic Damping Control.
For the first time in a U.S. 5 Series model, electronically controlled shock absorbers are available on the 5 Series Gran Turismo. Dynamic Damping Control, first introduced on the 2009 BMW 7 Series, is an evolution of the Electronic Damping Control (EDC) that has been available on several BMW models. On the 5 Series Gran Turismo, Dynamic Damping Control (DDC) is combined with Active Roll Stabilization (ARS) into an option called Adaptive Drive.

Dynamic Damping Control adjusts the shock absorbers to any level of firmness between their softest and firmest settings, quickly adapting to road conditions and the driver’s demands at any given moment. Suspension control is always at the optimum level for current road conditions, vehicle speed and the load the vehicle is carrying (again, passengers and luggage). The shocks default to the softest appropriate setting for the vehicle’s speed, and when the vehicle encounters an irregular road surface, they adjust instantaneously to the optimum firmness level to control ride motions, preserve riding comfort and maintain adhesion to the road. At highway speeds, the system can encounter a pothole at a front wheel and adjust the rear-wheel damping before it reaches the same pothole.

Dynamic Damping Control is the first BMW system to vary the shock absorbers’ jounce and rebound strokes (wheel moving upward and downward) both steplessly and independently; this capability results in a unique combination of desirable firmness (for handling) and excellent comfort on uneven road surfaces.

The other element of Adaptive Drive: Active Roll Stabilization (ARS).
This high-tech system reduces body roll, popularly known as “lean,” in cornering. It improves handling by virtue of better suspension geometry (wheel angles relative to vertical), but there is a psychological component as well: Drivers and passengers alike marvel at the “flat cornering” that results from ARS.

Whenever the vehicle enters a corner or curve, or begins an avoidance maneuver, “lateral acceleration” is generated. This is read by a sensor, which transmits a signal to the ECU. The ECU processes this signal and transmits it to the valve/sensor block. In turn, the valve/sensor block determines the hydraulic pressure applied to the active anti-roll bars to control body roll.

The key word here is “active.” Active Roll Stabilization –
1. Generates resistance to body roll by twisting the front and rear anti-roll bars.
2. Does so in a stronger and more “tailored” way than can conventional anti-roll bars.
3. Does not offer resistance to bumps in straight-ahead driving, as do conventional anti-roll bars.
4. Increases the vehicle’s maximum cornering capability.
5. Improves steering response, particularly in the range of cornering where body roll is most tightly controlled.

Driving Dynamics Control: the driver chooses vehicle dynamics.
Adjacent to the E-shift lever is the Driving Dynamics Control selector (logically, on the driver’s side). Driving Dynamics Control provides three standard settings that tailor vehicle behavior to different moods. The settings are Normal, Sport and Sport+; vehicle parameters affected include:
• Engine throttle response
• Transmission shift characteristics
• Power-steering assist level
• Dynamic Traction Control mode (Sport+).

In 5 Series Gran Turismo models equipped with optional Adaptive Drive, a fourth mode, called Comfort, is added. This puts the Dynamic Damping Control into its most comfort-oriented mode. Clearly the vehicle’s driving dynamics can be widely adjusted by these different calibrations of so many elements.

Another control in this area affects Dynamic Stability Control alone. A brief push on the DSC button switches the system to Dynamic Traction Control, in which DSC’s intervention threshold is raised. A long push on the same button de-activates DSC altogether, though two of its functions (antilock braking and electronic limited-slip) are always active.

Electronic limited-slip differential
When DSC is fully de-activated, an electronic limited-slip differential comes into play in vigorous driving. By judicious application of the individual rear-wheel brakes, DSC simulates a traditional mechanical limited-slip differential. This has the effect of better apportioning power between the two rear wheels and thus improving traction in this driving situation.

Intelligent driving dynamics: Integrated Chassis Management and FlexRay
All such driving-dynamics functions are coordinated and overseen by BMW’s Integrated Chassis Management. Via sensing and analysis of a multitude of inputs, this powerful electronic control scheme applies and governs the interaction of these functions to ensure maximum stability. Under rapidly changing conditions, such as changing road surface, spontaneous steering input, abrupt acceleration or sudden braking, ICM reacts with ultra-quick and ultra-precise interventions via the DSC actuators plus – where present – Dynamic Damping Control, Active Roll Stabilization and Integral Active Steering.

For this extremely sensitive and powerful networking of functions, the 5 Series Gran Turismo employs FlexRay data-transmission technology. Developed by a consortium of which BMW is a leading member, FlexRay achieves heretofore unheard-of communication speed, some 20 times that previously possible. In the 5 Series Gran Turismo, up to 16 electronic control units can be networked; in no other competitive automobile can longitudinal, lateral and vertical vehicle motions be so precisely monitored and influenced. BMW was the first motor-vehicle manufacturer to offer FlexRay technology in production vehicles; it made its debut in the current X5, is also employed in the X6 and now comes to BMW automobiles in the new 7 Series and 5 Series Gran Turismo.

Generously dimensioned disc brakes with composite front rotors.
In this patented construction, each front brake rotor (disc) consists of two pieces: the high-carbon cast-iron outer portion, which functions conventionally as the surface onto which the brake pads grip to slow or stop the vehicle; and an aluminum “hat” in the center, which mounts the rotor to the vehicle. The concept’s advantages include reduced unsprung weight, complementing the aluminum suspension in benefiting ride comfort and road adhesion.

Reduced rotor deformation under hard braking is the other benefit. This means less tendency of the brakes to vibrate when hot, and reduced likelihood of rotors cracking under extreme heat conditions.

The Gran Turismo’s brake system is supported by the comprehensive functions of Dynamic Stability Control (DSC). These include antilock braking (ABS), Automatic Stability Control (ASC), Cornering Brake Control and Dynamic Brake Control; each of these functions contributes to vehicle stability and some of them do so specifically during braking. Other braking enhancements via DSC include Brake Fade Compensation, which compensates for loss of braking power (fading) under hard or repeated brake use; Brake Standby, which snugs the brake pads up to the rotors upon sharp deceleration to reduce inherent lag time in brake application; and Brake Drying, which brings the pads to the rotors periodically during wet-weather driving to keep the brakes ready. Automatic Hold, a function included in the Gran Turismo, 7 Series, X5 and X6 models, holds the brakes for an indefinite time when the vehicle is stopped anywhere, preventing rollback or creep; it can be activated or de-activated by the driver with a console button.

Wheels and tires: 18-in. standard, 19- or 20-in. optional, run-flat across the board.
All Gran Turismo wheel/tire equipment is decidedly sporty. The 550i Gran Turismo comes standard with 18 x 8.0 alloy wheels, fitted with 245/50R-18 run-flat all-season tires. With the Sport Package, there are two choices of special wheel/tire equipment, each with performance-type tires (also run-flats) and distinctive wheel designs: 19 x 8.5 front/19 x 9.5 rear, with 245/45R-19 front / 275/40R-19 rear; or 20 x 8.5 front/20 x 10.0 rear, with 245/40R-20 front / 275/35R-20 rear.

7. Body and safety.
Variable passenger and cargo space, comprehensive safety features.

• A first: aluminum doors with frameless windows.
• Immensely strong body structure, extensive measures to protect pedestrians.
• Bi-modal trunk with unique design and functional features.

The 5 Series Gran Turismo’s innovative and multifaceted character springs from many factors, but most of all from the unique attributes of its body. Here, conceptual ideas have been translated into the actual vehicle design and engineering with BMW’s typical function-oriented approach and premium quality. New, technologically advanced solutions ensure that BMW’s goals of sporty elegance, personal luxury and contemporary versatility are achieved in convincing ways; in turn these are the foundation of a new kind of BMW experience.

Beyond these more subjective attributes, the Gran Turismo embodies in its intelligently conceived body structure a meticulously coordinated system of optimized passive safety and occupant protection. For example, the use of high-strength steels as well as a large proportion of aluminum helped BMW realize great structural strength with relatively moderate weight. In particular, the important relation of torsional rigidity relative to vehicle footprint and weight has been brought to a new high.

Innovative in design and construction: the aluminum doors.In addition to the Gran Turismo body’s hood and front spring towers, its four doors are of aluminum, saving a significant 61.7 lb. compared to steel. Also, this is BMW’s first 4-door with frameless windows, which contribute greatly to the interior’s bright, airy ambiance. (Optionally, power-operated sunshades are available for the rear door windows.) Producing the sharp contour lines which are a part of today’s BMW look in aluminum required intensive engineering effort.

Unique: 2-piece bi-modal trunk with full, independent functionality.
To achieve maximum convenience and versatility of loading various cargo items, BMW developed a remarkable system, consisting of a smaller, trunklid-like opening under the rear window and a large liftgate similar to that of BMW’s X models. The “trunklid” can be opened separately; when the liftgate is opened it includes the lower lid. (As part of the optional Premium Package, liftgate operation is powered.)

The overall frame for this assembly is of aluminum, of great strength and unprecedented precision of manufacture and fit. Both sections are on tubular hinges; the liftgate comes standard with Soft Close, requiring only to be set down and then being drawn tight automatically. Opening of either section may be accomplished via buttons on the remote or inside the cabin. Each section has one of BMW’s convenient grip cutouts to facilitate pulling it down for closing.

Panoramic moonroof: more light, strength and head room.
The U.S. model of the 550i Gran Turismo comes standard with a new version of BMW’s dual-panel Panoramic moonroof. Encompassing about 55% of the roof’s surface area, the entire assembly is 45.7 in. long and 37.1 in. wide; its forward glass panel slides open 17.3 in. or tilts upward. The rear glass panel is fixed, bound to the roof so as to serve as a highly rigid part of the overall body structure.

The moonroof’s forward wind deflector rises to different heights on the basis of vehicle speed, more effectively taming potential low-speed air drumming or high-speed wind road; its interior sunshade is also powered. A further refinement is the moonroof’s harmonious integration into the roof contours: its front edge is curved parallel to the roof’s front edge for an unusual and subtle design touch.

Exemplary occupant protection.
Robust structural members, generously dimensioned and precisely defined deformation zones, and sophisticated electronically controlled restraint systems constitute the 5 Series Gran Turismo’s state-of-the-art concept of occupant protection. In a frontal crash, impact forces are channeled over multiple paths into the floor structure, side members, front bulkhead and roof; absorbed in deformation zones; and just generally kept away from the passenger compartment. For the force paths, multi-phase and heat-treated steels are employed extensively.

In the interior, 2-stage front airbags, seat-mounted side-impact airbags and curtain-type, front-to-rear head protection are all standard equipment, controlled according to crash type and severity for optimum effect. Airbags that are not needed for the impact at hand are not deployed, yet remain ready to deploy in case of a secondary impact. The power tilt/telescopic steering column includes a robustly dimensioned deformation section, improving its ability to protect the driver from structural intrusion into the cabin.

All seating positions are equipped with 3-point safety belts; all have force limiters, the front ones also adding automatic tensioners plus pre-tensioning during emergency braking. For protection against head and neck injuries in a rear-end impact, the front seats include active head restraints, which deploy up to 2.36 in. forward and 1.57 in. upward as required – all between the time the rear impact begins and when the occupants’ heads would be thrown rearward.

The rear outboard seating positions are equipped with LATCH (Lower Anchors and Tethers for Children) for securing a child restraint seat.

BMW Assist, Enhanced Roadside Assistance, Enhanced Automatic Collision Notification – all standard with the 5 Series Gran Turismo.
Every new 5 Series Gran Turismo comes standard with BMW Assist, a system of telematics and user services of sweeping scope. Among the services included in the BMW Assist Safety Plan – whose subscription is paid by BMW for the first 4 years after purchase of a new vehicle, – include emergency services, a wide range of roadside-assistance benefits, stolen-vehicle recovery, and Enhanced Automatic Collision Notification. In the event of a severe accident, the BMW Assist system automatically transmits the vehicle’s location and crash information to a response specialist, who will speak to the vehicle occupants to determine if they are all right, while a second specialist requests dispatch of emergency services as needed.

Features that can help prevent accidents: also standard.

All BMW vehicles excel in features and attributes that make driving both safer and more pleasant. Here are some key points about the 5 Series Gran Turismo features that contribute to active safety:

Xenon Adaptive headlights with auto-leveling – by providing outstanding forward illumination, “steering” around curves and staying aimed correctly, these advanced headlights benefit the BMW driver and passengers as well as those in other vehicles.

Cornering lights – provide targeted illumination to the side for turning corners or sharp curves at relatively low speeds.

Automatic headlight control – turns on the headlights in conditions of marginal ambient light, when the driver might not yet think of doing so.

Halogen foglights set into the front end’s lower air intake.

Rain-sensing windshield wipers – standard on all current BMW models.

Park Distance Control – reduces likelihood of fender-bending and bumper-scratching low-speed collisions. Standard front/rear on the 5 Series Gran Turismo.

Adaptive brakelights – indicate to following drivers when the BMW driver brakes hard, potentially lessening the probability of a rear-end collision.

Responsive, predictable handling made possible by advanced and sophisticated suspension design, generously dimensioned wheels and tires, accurate steering, and optional features like Adaptive Drive and Integral Active Steering.

Powerful 4-wheel ventilated disc brakes with antilock braking (ABS) – enhanced by the Dynamic Stability Control system’s braking features.

Run-flat tires – eliminate necessity of potentially dangerous roadside tire changes.

Tire Pressure Monitor – via direct measurement of pressure at each tire, alerts driver to pressure loss.

Auto-dimming interior and exterior mirrors – by automatically reducing glare from headlights and foglights of vehicles behind, improve BMW driver’s ability to see ahead and concentrate on driving.

Dynamic cruise control – can apply brakes lightly to help control downhill speed, and reduce speed in curves.

Update 5/1/07

BMW 5 SERIES FOR 2008:

The most powerful 6-cylinder Sedans and Sports Wagon yet headline a thoroughly revised 5 Series

Woodcliff Lake, New Jersey, May 1, 2007… Building on last year’s updates, BMW’s 2008 5 Series Sedans and Sport Wagon receive another significant freshening and, in the case of 6-cylinder models, a major boost in power and efficiency. Complementing the power increase, a thoroughly revised interior, new technological features and a freshened look front and rear ensure this benchmark collection of rear and all-wheel-drive Sedans and Sports Wagon will maintain their place at the forefront of the mid-size luxury class.

These early release 2008 5 Series models represent the most significant update since their introduction in 2003. Adopting the new engines introduced in the 3 Series Coupe, the 6-cylinder Sedans and Sport Wagon receive new model designations, reflecting a marked boost in power. Last year’s 525i and 525xi both get the new, 230-horsepower iteration of BMW’s remarkable aluminum/magnesium composite N52 engine, along with new 528i and 528xi nomenclature. Similarly, the 530i and 530xi become the 535i and 535xi, the new designations signifying the addition of BMW’s latest, 300-horsepower N54 twin-turbo inline-6. Included in this upgrade is the 2008 535xi Sports Wagon, its 300-horsepower eclipsing the old 290-hp V-8 540i and making it the most powerful Sports Wagon BMW has ever offered in the U.S. While the current 550i retains its 360-horsepower 4.8-liter V-8, the mid-size flagship receives a new Sport Package with 19-inch wheels and new body treatments, along with the updated interior and exterior freshening.

In addition to the horsepower boost, new performance features include a quicker-shifting Sport Automatic transmission for the rear-drive 535i and 550i Sedans, which also provides fingertip shift control via steering-wheel-mounted paddles. This is in addition to the new, updated STEPTRONIC that is now a no-cost option on all 5 Series models. New Sport Package contents bring 18-inch wheels and run-flat performance tires to all 6-cylinder models, including staggered-width 18-inch tires on the rear-drive 535i Sedan. The same 18-inch wheel and tire option is also available on Sport Package-equipped 535xi models as a further extra-cost addition.

New technological features also make their appearance for ’08. First among these is BMW’s Lane Departure Warning system, a camera-based system that monitors lane placement, and discreetly notifies the driver via mild steering wheel vibration of any motions that might indicate an inadvertent lane change. The convenience of Active Cruise Control is extended via a new Stop and Go feature, which enables the system to function even in heavy traffic. Active Cruise allows the vehicle to come to a complete stop without losing its setting, then accelerate back up to set speed with only a touch of the accelerator pedal from the driver. Audio options expand with a USB Adapter for an iPod or MP3 player. And BMW’s leading-edge iDrive system adds a row of programmable “favorites” buttons, which can be used for anything from radio-station presets to pre-programmed destinations with the optional navigation system.

As in the past, all BMW automobiles and SAVs include BMW Ultimate Service, which includes 4 year, unlimited mileage Roadside Assistance, 4 year / 50,000 mile New Vehicle Limited Warranty and BMW Maintenance Program at no extra cost. In addition, all 5 Series BMWs also include a 4 year membership in BMW Assist Safety Services as standard equipment.

A more-powerful base engine, twin-turbo performance, and a superlative V-8 all complement the most sophisticated chassis in the class.

BMW’s engines have become legendary for their performance, smoothness, and sophistication—attributes that apply equally well to BMW’s inline-6s and V-8s. The 5 Series offers three of these engines—two 6-cylinders and one V-8—including the company’s first turbocharged engine in more than three decades. From the base 528i to the range-topping 550i, the 5 Series offers the most impressive range of powerplants in the class, all backed by 6-speed transmissions, manual or automatic.

As the first full-production aluminum/magnesium composite engine every offered, the 3.0-liter N52 inline-6 carries on BMW’s tradition of building cutting-edge engines that combine outstanding power, unparalleled refinement and excellent fuel economy. For 2008, this engine receives a boost to 230 horsepower, making the 528i/xi Sedans the most powerful entry-level 5 Series ever offered. Similarly, the new 300-hp twin-turbo 535i/xi Sedans and Sports Wagon are the quickest 6-cylinder-powered 5 Series cars yet. And the range-topping 550i offers the same 360-horsepower V-8 as BMW’s 750Li Sedan in a sportier, more compact platform.

These exemplary engines reside in a chassis that includes aluminum suspension, large-diameter disc brakes, performance tires on 17-, 18- or 19-inch wheels and options such as Active Steering and Active Roll Stabilization. With either xDrive all-wheel-drive or traditional rear-drive, the 5 Series sets the standard for handling, ride and braking for the class.

BMW’s inline 6-cylinder engines: Class-leading distinction, performance and efficiency

Almost all vehicle manufacturers of 6-cylinder engines have adopted the V-6 format, whose compactness is advantageous in small or midsize cars with front-wheel drive. By contrast, BMW’s inline 6-cylinder engines are outstanding for their smoothness and sound, and BMW customers treasure them for these attributes. Thus BMW retains the inline format while developing it toward reduced weight, more compact dimensions – and ever more brilliant performance, smoothness and sound. An increase in fuel efficiency and even tighter control of emissions were also set as goals for this BMW engine generation, which currently powers the 2008 528i/xi 6-cylinder models.

N52 engine: magnesium/aluminum composite construction and Valvetronic variable valve lift

As the “base” level powerplant, the N52 engine offers a wide variety of benefits in the 528i and 528xi Sedans. In addition to offering a further development of BMW’s traditional inline 6-cylinder engine, the aluminum/magnesium composite construction reduces weight compared to an all-aluminum design, which also enhances weight distribution. The Valvetronic variable valve lift improves performance and fuel efficiency, while detail refinements such as an electric water pump and volume-controlled oil pump also increase efficiency. The result is an engine that retains the legendary smoothness of BMW’s inline 6-cylinder engines, while offering an outstanding balance of performance and fuel efficiency.

Compared to the previous M54 6-cylinder, the N52 offers a wide variety of benefits:

• Higher revving ability. The “redline” is 7000 rpm, vs. 6500 for the M54.

• Reduced weight – 22 lb. less. Had BMW engineers developed the previous engine to meet their goals, it would have added about 30 lb. – and thus would have weighed fully 52 lb. more than the new engine does.

• More compact – Because there is just one external drive belt, vs. the previous two, overall engine length is about an inch shorter. Here are details of how this dramatic progress was achieved – over an engine that was already outstanding in all these respects:

Evolved Valvetronic variable valve lift. This exclusive, patented innovation, enhancing the performance and fuel efficiency of BMW’s V-8 and V-12 engines since 2002, varies valve lift to control engine power, dispensing with a conventional throttle. Valvetronic enhances engine power, torque and efficiency. Compared to the original Valvetronic system, introduced on BMW’s V-8 and V-12 engines in 2002, the N52 engine’s 2nd-generation system benefits from several evolutionary improvements:

• Maximum engine speed increased by 500 rpm. Enabled by making Valvetronic’s reciprocating parts more rigid.

• Maximum intake-valve lift increased from 9.7 mm to 9.9 mm, which contributes to the increase in maximum power output.

• Greater maximum intake-valve acceleration. Less time is spent opening and closing the valves; thus they are effectively open longer.

• Phasing of the two intake valves. Starting from minimal intake-valve lift (i.e. idling), an increase in engine load causes the lift and timing of intake valve 1 to increase faster than that of valve 2. At its maximum, this phasing has valve 1 lifting 1.8 mm more than valve 2; at about 6 mm, the two valves are again “in synch.” This refinement enhances fuel economy under low-load driving conditions.

Improved combustion chambers. Subtle refinements to the combustion-chamber shape conspire with the intake-valve phasing to create more stable combustion, with benefits to fuel efficiency and emission control.

Further evolved VANOS. Double VANOS ¹ is a familiar feature of all current BMW engines. The range over which intake-valve timing can be varied has been increased by 10º, achieving yet another de-throttling effect.

Higher fuel-injection pressure results in an improved injection spray, helping reduce raw hydrocarbon emissions in a cold engine.

All-new engine electronics. Among many innovative details, the basic ignition and valve timing functions are duplicated. The first part was optimized for fuel consumption and emissions; the second part was determined according to pure driving parameters. Depending upon how perfectly the engine is running at any time, control interpolates between the two strategies. Under ideal conditions, the engine always runs with its lowest possible fuel consumption. In case of poor fuel quality or unfavorable environmental conditions, the control parameters prioritize driveability. With introduction of this latest version, the engine’s electronic control module has been upgraded in calculating capability and renamed from MSV70 to MSV80.

Magnesium/aluminum composite construction. An important innovation – a world’s first in modern times and exclusive to BMW. Structurally, the new engine block consists of three major castings:

• Bedplate (magnesium alloy ^{^[3]}). The lower portion of the block (crankcase); similar in concept to a construction element found in some racing engines as well as the M5 and M6’s 500-hp V-10. The bedplate combines with the upper crankcase to form the block’s outer shell; the result is an ultra-rigid engine structure.

• Upper crankcase (magnesium alloy). Joining the bedplate at the level of the

crankshaft (main) bearings, this too is a weight-saving casting. It is mounted onto

• Insert (silicon-impregnated aluminum alloy, or Alusil). In this sense, the N52’s construction resembles that of current BMW V-8 and V-12 engines, though these blocks are all-Alusil.

In addition to the magnesium construction, other weight-saving materials include hollow camshafts, saving a remarkable 2.6 lb. each. Beginning as steel tubes, the camshafts are shaped in a hydroforming procedure, subjected from the inside to a water pressure of 58,000 lb./sq in. against outer forms to achieve the cam profiles. The engine’s camshaft cover is of a new, weight-saving plastic material. (On earlier N52 engines, it was of magnesium.) And the chain camshaft drive, a high-durability, low-maintenance feature of all current BMW engines, has an aluminum chain tensioner that also saves weight. As a final weight-reducing element, the exhaust headers’ flanges are formed from 2-mm-thick steel, significantly lighter than the 12-mm flanges used in the M54.

Electric water pump, electronically controlled according to coolant and oil temperatures at any moment. It runs only as much as needed, and in doing so consumes a maximum of 200 watts vs. up to 2 kilowatts (10 times as much) for a conventional pump. The electric pump has numerous tangible benefits:

• By requiring less power, contributes to the engine’s increased power output.

• Faster engine warmup, because it doesn’t circulate coolant when the engine is cold.

• Provides coolant circulation for the Heat-at-Rest feature now included in the climate control.

Variable-volume oil pump. To supply pressure to the VANOS ¹ at all speeds and temperatures without excess capacity at high engine speeds, BMW engineers developed a new type of oil pump with these advantages:

• Contributes to the engine’s increased power output, by requiring less power from

• Doesn’t require a bypass to divert excess flow, which can be up to 80% with a conventional pump. This also avoids possible excess oil temperatures and oil foaming.

Oil/coolant heat exchanger. Another feature that speeds engine warmup; during this phase of operation, it transfers heat from the coolant to the oil circuit. Under conditions of high engine power and high oil temperatures, it performs the reverse, transferring heat from the oil circuit to the coolant, from which the engine cooling system then removes excess heat.

While those traits illustrate the improvement over the previous-generation BMW inline-6, the N52 engine also benefits from additional power enhancements for 2008. Compared to its most direct predecessor, the 215-hp 525i/xi engine of 2007, the 230-hp 528i/xi engine delivers a tangible performance boost:

• 0-60 mph in 6.5 sec. for the 528i Sedan with manual transmission, compared to the ’07 525i Sedan’s 7.3 sec. (In fact, the new 528i nearly matches the 2007 530i from 0 to 60 mph, 6.5 sec. vs. 6.4!)

• 0-60 mph in 7.1 sec. for the 528xi with manual transmission, vs. ’07 525xi Sedan’s 7.9 sec.

As BMW’s other approach to modern 6-cylinder power, the N54 is as innovative as the N52 engine, though these different innovations are aimed at further increasing performance. A pair of relatively small turbochargers boost performance significantly, but minimize the traditional turbocharging response lag (“turbo-lag”). In addition, high precision direct fuel injection further enhances performance and fuel efficiency. Finally, high-tech heat-resistant materials in the engine help facilitate performance. With the N52 naturally aspirated engine and this even-newer N54 turbocharged unit, BMW is announcing to the world its approach to high performance: Instead of ever-larger engines, BMW will achieve its performance goals with smaller, lighter, more efficient and cleaner-running engines.

First: the 300-hp N54 engine is anything but simply a turbocharged version of the 230-hp N52. Several new “core” features distinguish it from the N52 and facilitate the higher performance level:

• All-aluminum structure. As attractive as the magnesium/aluminum concept is for saving weight, the extra strength of all aluminum construction was deemed necessary for the increased power and torque. Some, but not all, of the mag/alu construction’s weight saving was lost. Like the N52’s, the N54 block is a completely new construction, with bedplate.

• Cast-iron cylinder liners. Whereas the N52 has an aluminum-silicon cylinder casting inside its magnesium crankcase, the N54 has cast-iron sleeves inside its aluminum crankcase.

• Different bore and stroke. The bore has been reduced from 85.0 to 84.0 mm; the stroke is increased from 88.0 to 89.6 mm. This gives greater cylinder-wall thickness – again to handle the higher stresses within the engine – but leaves the engine’s displacement essentially unchanged at 2979 cc vs. the N52’s 2996 cc. Both round off to 3.0 liters.

• Conventional valvegear. In the research and development that led to the N54 engine, BMW’s engineers found that Valvetronic’s variable intake-valve lift did not lend its advantages to the turbocharged engine. They remain valid for the non-turbo engine.

• Moderately increased weight. Naturally, the aluminum construction, iron cylinder liners and turbochargers add some weight to the N54; so do solid camshafts, compared to the N52’s hollow ones. Altogether, the N54 weighs 419 lb., vs. the N52’s 357. With this moderate weight increase, of course, come 70 more horsepower and those 300 lb-ft. of torque; BMW engineers point out that a 4-liter engine of this performance would weigh a good 150 lb. more!

Now, here are the technologies and features that actually produce the dramatically increased power and – especially – torque that characterize the new N54 engine:

Twin turbochargers. Turbocharging is a familiar form of increasing the performance of combustion engines – it has been around in various forms for 100 years. At various times, BMW has set milestones in the development of turbocharging: in 1973, the 2002 Turbo offered 170 hp, vs. 130 for its non-turbo stablemate the 2002 tii. In 1983, a BMW powered Brabham racecar was the first turbocharged vehicle to win a Formula 1 championship.

Yet over its history, turbocharging has also suffered some daunting drawbacks. If, as was usual, a single turbo was used, it often had an unacceptable degree of “turbo lag” – the lag between the time the driver mashed down the accelerator pedal to the time when the turbo responded. This was at its worst at low engine speeds. Another was relatively high fuel consumption. And finally, the available materials didn’t always fare well under the high-heat, high-rpm operation of a turbocharger, which gets its energy from hot, flowing exhaust gases and typically spins well past 100,000 rpm. After the 2002 Turbo, which ironically was introduced just about the time of the first international energy crisis, BMW set turbocharging aside. (Except for diesel engines, where turbocharging is a highly conventional, almost indispensable, power enhancer.)

The N54 turbocharging concept addresses both turbo lag and durability concerns. By utilizing two small turbos – each one serving three cylinders – BMW has reduced the inertia that creates turbo lag. To quote Dr. Burkhard Göschel, BMW’s Board Member for Engineering, turbo lag “has now become a thing of the past. The engine is agile, and it performs like a big, naturally aspirated engine, but with much better mileage.”

Materials progress, always a factor in advancing the capabilities of engineering and technology, figures here too: BMW has drawn upon innovative and heat-resistant materials from space technology to facilitate the twin turbos’ dramatic contribution to performance. All turbo components subjected to the most extreme heat (i.e. the exhaust stream) are made of advanced steels that can withstand up to 1050ºC, or 1920ºF.

Direct fuel injection with piezo injectors. Fuel injection, as we have (mostly) known it over the decades in which it has become a feature of all contemporary automotive engines, has been of the port type: the fuel is injected into the engine’s intake ports, where air passes through on its way to the cylinders. Direct fuel injection sprays fuel directly into the cylinders, or more precisely the combustion chambers. If this were as simple as it sounds, direct injection would long since be commonplace. But the cylinder is a much hotter, higher pressure place than the intake port and poses big hurdles for the fuel injectors and the optimization of just how, when and how much fuel is squirted in. Until now, the only BMW gasoline engine with direct injection has been the 760Li V-12 engine, where this technology brings advantages in fuel efficiency, power, torque and emission control.

The N54’s direct injection is a 2nd-generation evolution of the 760Li’s system, and a key factor in achieving BMW’s goals for this engine. Its main advance over the 1st-generation system is that it gives the engineers greater degrees of freedom in the calibration of fuel quantity and timing and the distribution of the fuel-air mixture in the combustion chamber. With this concept, it’s possible to utilize a “leaner” mixture – thus less fuel. The advantages in fuel efficiency, power, torque and emission control are more significant.

A further advantage to torque and fuel consumption is the cooling effect of fuel being injected into the hot combustion chambers. Typically, to avoid overheating, turbochargers have had to make do with a lower compression ratio. That ’73 2002 Turbo, for example, had a low 6.9:1 ratio, vs. the non-turbo 2002 tii’s 9.5:1; a more contemporary example is the Volvo S60 2.5 Turbo engine’s 9.0:1 compression ratio vs. it’s non-turbo counterpart’s 10:3:1. As a higher compression ratio benefits both fuel efficiency and (especially low-speed) torque – traditional turbo engines have suffered on both counts – the N54 benefits mightily: its compression ratio is 10.5:1, almost exactly the same as the non-turbo N52’s 10.7:1!

Positioned centrally in the combustion chambers for optimum combustion, the injectors – those critical components that inject the fuel into each cylinder’s combustion chamber – are subject to especially high temperatures. A new-type piezo injector is another essential element in attaining the ambitious performance/efficiency/emissions goals with the necessary long-term durability: A “stack” of piezo crystals reacts lightning-fast to impulses from the engine electronics, governing the injector needle’s opening stroke and duration for ultra-precise control of fuel quantity.

According to researchers who led the piezo injector’s development, alone it contributes 2-3% fuel savings and 20% less emissions. Its operating principle involves applying mechanical pressure to a non-conducting crystal to produce an electrical impulse; in turn, this impulse is so fast that it significantly reduces the injector’s response time.

Air-to-air intercooling. Turbocharging typically includes intercooling of the engine’s induction air, that is, some method of cooling the compressed air that emerges, heated up by the compression process, from the turbocharger(s). Sometimes it’s done with coolant; in this case it’s done indirectly by outside air. Intercooling is desirable, even necessary, to reduce the temperature of incoming air to help preclude detonation or “knocking” that can reduce power or, in the extreme, damage the engine. Of course the N54, like the N52 and all other current BMW engines, has knock control.

High-rpm concept. This is shared with the N52 engine, and also contributes significantly to the engine’s performance character. Like the N52, the N54 has a 7000-rpm redline. Its maximum power occurs at 5800 rpm – actually lower than the 530i’s 6600 and the new 528i’s 6500 rpm – but power stays high and vigorous well toward that 7000 rpm.

The bottom lines. The peak power of 300 hp has already been mentioned; this is fully 45 higher than the 530i, and 70 hp up on the 528i. The torque increase is just as impressive: 300 lb-ft., vs. the 530i’s 220 and 528i’s 200. At least as important is the fact that this engine can deliver its peak torque all the way from 1400 rpm (not far above idling!) to 5000 rpm. Finally, 300 lb-ft. is significantly better than competing 3.5-liter non-turbo engines deliver: Lexus GS 350, 274 lb-ft. at a high 3600 rpm; Infiniti M35, 268 lb-ft. at an even higher 4800 rpm. Compared to the 528i’s 200 lb-ft., the N54’s 300 lb-ft. is fully 50% greater. BMW engine engineers assert that to achieve this kind of torque increase, it would have taken a 4-liter naturally aspirated engine. That would have weighed too much and its fuel consumption would have been unacceptably high. For this reason, say the engineers, “we did not take that path.”

One BMW engine engineer, Udo Lindner, goes so far as to assert that the N54 has “the torque of a diesel but the revving capability of a gasoline engine.” Diesels, currently very popular in Europe and capable of stump-pulling torque, operate at rpm levels well below those of gasoline engines, so he’s saying that the N54 delivers the best of both worlds.

The other bottom line, surely the most important to performance enthusiasts, is dramatically quicker acceleration compared to their predecessors:

• 0-60 in 5.6 sec. with automatic transmission, vs. 6.9 sec. for the 530xi Sedan

• 0-60 in 5.8 sec. with automatic transmission, vs. 7.3 sec. for the 530xi Sports Wagon

With their standard manual transmissions (SOP 09/07), all these pairings will offer comparable improvements. As in all 5 Series cars, top speed is electronically controlled at 150 mph.

With 4.8 liters, the 550i’s V-8 delivers brilliant performance. Peak power is 360 hp; likewise, peak torque is 360. With its standard 6-speed manual transmission the 550i attains 60 mph in just 5.4 sec. from rest; with automatic, the new model does 0-60 in 5.5 sec.

Aside from such impressive test data, this evolution pays off in real-world performance, as media critics have found in their test drives:

• Edmunds.com, posted March 21, ’05: “It’s refined and athletic like the old 4.4, but its torque band seems to go on forever.”

• auto motor und sport, Germany, March 2, ’05: “The [more powerful V-8] engine provides not just impressive initial thrust, but also a level of response over its entire rpm range that meets high expectations.”

All BMW models are standard-equipped with Dynamic Stability Control, which provides a wide range of traction and stability functions.

While retaining all the functions or the previous DSC, a revised system appeared in the 5 Series and other BMWs in 2006. This Enhanced DSC adds a wide array of customer-relevant functions that make driving even safer and more pleasant. They are:

• Brake Fade Compensation. Brake fade occurs as the brakes heat up under hard use; a given degree of deceleration requires more pressure on the brake pedal. As brake temperature rises, this function automatically compensates by increasing the hydraulic pressure relative to pedal force.

• Brake Standby. When the driver lifts off the accelerator pedal abruptly, DSC recognizes that sharp braking may be about to occur and applies just enough pressure in the brake system to snug up the pads against the rotors. Thus by the time the driver’s foot reaches the brake pedal, the lag time normally resulting from bringing the pad to the rotor is eliminated, reducing stopping or deceleration distance.

• Brake Drying. Acting on input from the rain sensor (an element of the standard rain-sensing windshield wipers), the pads are periodically brought up to the rotors – just enough to eliminate any film of water between pads and rotors, but not enough to cause a brake application.

• Comfort Stop. Especially with an automatic transmission, unless the driver consciously eases off on the brake pedal, a jerk can occur as the vehicle comes to a stop. Comfort Stop eases off, making for smoother stops. Currently only in the rear-wheel-drive models.

• Start-off Assistant. Briefly holds the vehicle when the brakes are released while stopped facing uphill. The driver can then start up without doing a ballet with the clutch, brake and accelerator (manual transmission) or rolling backward on a steep hill (automatic transmission).

• Modulated ABS function. “Analogized” control of the DSC brake valves makes the anti-lockup function (ABS) smoother. Instead of simply being fully on or off, application and release of these valves are now modulated.

Long one of BMW’s true core products, the 5 Series elegantly defines the middle of the line with compact exterior dimensions, ample interior space and a masterfully calibrated blend of sport and luxury. Appearing in ’04 in its current generation, the Series maintained trim exterior size while increasing interior space and introducing new technologies – including an aluminum front-end structure, available Active Steering and Active Roll Stabilization, evolved suspension and a further developed iDrive control system.

That the current generation carries on the 5 Series tradition brilliantly is supported by this quote from Motor Trend’s March ’05 issue: “Here’s a thoroughbred, the product of decades of setting the benchmark all other automakers’ sport sedans aspire to. Just look at the stance, the way the body sits on the chassis, ready to pounce on any opportunity to show its stuff on a challenging stretch of road. The smoothness and flexibility of BMW inline-sixes are legendary, and the 225 horses of the 2979-cc engine seem more spirited than their numbers might otherwise suggest. And BMW is one of the only automakers courageous enough to offer a 6-speed manual gearbox in a $50,000 sedan.”

With even more powerful engines, available xDrive and the new Sports Wagon to extend its capabilities, the 5 Series is today’s representative of this fine tradition.

In terms of safety and security, the 5 Series is a state-of-the-art vehicle from a state-of-the-art vehicle maker. With an extensive array of standard features, and such available options as the new Lane Departure Warning system, Night Vision and Head-up Display, the 2008 5 Series remains an industry leader and fully representative of BMW’s safety values. Key standard features include:

• Dual front-impact Supplementary Restraint System (SRS) with dual-threshold deployment, 2-stage Smart Airbags – optimized for shape and deployment characteristics.

• Front safety belts with automatic tensioners and force limiters – standard on all models.

• Rear safety belts with automatic tensioners – included with the optional rear-seat side-impact airbags.

• Automatic-locking retractors (ALR) on all passenger safety belts for installation of child restraint seats.

• LATCH attachments at the outboard rear seating positions for child restraint seats.

• Rear-seat side-impact airbags – optional at nominal extra cost, so that customers can make their own choice in this matter.

• Head Protection System – front-to-rear via BMW’s Inflatable Tubular concept; a long airbag deploys from the ceiling, suspended on a “sail.”

• Active front head restraints – included with the front Multi-contour seats that are optional in all 5 Series models. Responding to impact sensors at the rear of the vehicle, the head restraints instantly pivot forward into close proximity with the occupants’ heads. Thus occupants are able, if they prefer, to adjust the restraints away from direct contact with their heads, yet gain optimum protection against whiplash or more serious head/neck injuries.

• Energy-absorbing padding of body-pillar and roof areas – specific padding at the A-, B- and C-pillars as well as along the roof above the doors.

• Fuel-tank design and location. Not only is the fuel tank designed to remain sealed even in severe impacts, its location has been chosen to provide optimum protection from impacts.

• Battery Safety Terminal – in case of a severe accident impact, breaks the high-current connection between the battery and starter cable. This helps prevent a possible short circuit in the electrical system.

• Automatic fuel-pump shutoff upon severe accident impact. In addition, the doors are automatically unlocked; the interior lighting and 4-way hazard flashers are switched on. Thus even after an accident, BMW’s safety strategy is still at work.

• Central locking system with double-lock feature. When the vehicle is locked from the outside, the double-lock feature prevents individual door-lock buttons from being pulled up; thus even if a thief has broken into the car, it isn’t possible to open the doors. Owners, however, have access to information on how to get out if one is locked in the vehicle from the outside.

• Alarm system with interior motion detector – standard on the 5 Series.

2008 brings with it a number of significant new technological options that complement an already extensive array of performance, comfort and safety features. For 2008 Package highlights include new contents for both Premium and Sport Packages for 6-cylinder models, as well as a revised Sport Package for the 550i Sedan.

Most of the optional features on the 2007 5 Series carry over to 2008, with few exceptions. Most notable, the Sequential Manual Gearbox has been discontinued, effectively replaced by the new Sport Automatic that arrives later in the year. The Premium Sound Package (ZPS), which included the Logic7 audio system and 6-disc CD changer, has been replaced by an individual stand-alone option for the Logic7 system and a BMW center-installed 6-disc changer.

Premium Package (528i/xi and 535i/xi models). Combines luxury and convenience features:

• BMW Universal Transceiver, a 3-function remote for garage doors and other external devices

• Auto-dimming interior and exterior mirrors, now including a power-fold feature

• 4-way power lumbar support for the front seats, which is standard in the 535i/xi.

• Power tailgate. Released from the interior or exterior switch or the remote, the tailgate opens electrohydraulically. Closing is from the exterior button.

Sport Package. Comes in essentially two forms, one for rear- and one for all-wheel-drive models:

• Active Roll Stabilization, which dramatically reduces body roll in corners and curves

535i Sedan – 18 x 8.0 front and 18 x 9.0 rear Star Spoke wheels (design #124) with 245/40R-18 front and 275/35-18 rear run-flat performance tires ⁴

550i Sedan – 19 x 8.0 front/19 x 9.5 rear wheels; 245/40R-18 front / 275/35R-18 rear performance tires ⁴

• Satin-chrome Shadowline exterior trim – all-black around the side windows replaces the standard black-plus-chrome window framing

• 20-way power front Multi-contour seats, in place of the standard 10-way power seats

• Includes only the exterior and interior features; no sport suspension or Active Roll Stabilization

• For all-weather attributes, retains standard wheels and all-season tires. Wheels described for 528i and 535i Sedans are available on 528xi Sedan, 535xi Sedan and 535xi Sports Wagon as stand-alone options in combination with the Sport Package. (Optional wheels on the 535xi Sports Wagon are 18 x 8.0 front and rear.)

Sport Automatic transmission – 535i and 550i Sedans only; requires the Sport Package. An even sportier alternative to the standard STEPTRONIC Sport setting, this 6-speed transmission offers crisper gearshifts in manual mode, and paddle shifters on the steering wheel. A leather boot around the console shifter also distinguishes this transmission from the standard STEPTRONIC.

Lane Departure Warning. A camera mounted on the windshield near the rearview mirror monitors lane position at all times at highway speeds. The central control unit projects the vehicle’s path based on that position. When the system projects that the vehicle will drift out of the lane, it will warn the driver by producing a mild vibration in the steering wheel. The warning is cancelled by the use of the turn signals, brake actuation, or below approximately 35 mph, indicating city traffic. The system can also be turned off via a switch on the multi-function steering wheel or in the iDrive menu.

Active Cruise Control. Employing a radar sensor unit at the front of the vehicle, ACC senses the speed of vehicles traveling ahead, adjusts the BMW driver’s speed to maintain following distance, and offers the driver additional control choices over the standard cruise control. 2008 adds a Stop & Go feature, which allows use in heavy traffic. The system can come to a complete stop and remain active; a touch of the accelerator pedal by the driver reactivates the cruise control so it can resume the set speed.

• Widely variable steering ratio; steering-wheel movements for parking maneuvers, U-turns and sharp corners are greatly reduced for amazing agility. With increasing vehicle speed, the steering becomes “slower,” favoring stability over agility.

• Vehicle stabilization; in critical situations, can intervene to preserve stability. For example, if the driver applies the brakes while driving on a surface with uneven traction (one side of the road slick, the other grippy), Active Steering can recognize incipient instability and steer against it.

Park Distance Control employs ultrasonic sensors in the front and rear bumpers to detect obstacles not be visible to the driver; emits an acoustic warning. Includes a vehicle diagram in the iDrive display, which graphically depicts obstacles’ locations. Standard on 550i.

Xenon Adaptive headlights with auto-leveling and low-speed cornering lights. Stronger, daylight-like illumination; headlights “steer” to enhance the driver’s view around curves and corners. This year adds low-speed cornering lights in the inboard headlamps, which illuminate nearby objects at speeds below 25 mph. Optional on 528i/xi models, standard on 538i/xi models and 550i.

Leather upholstery – though included in the Premium Package, also available as a stand-alone options. Standard on 550i.

Light Poplar wood interior trim. The Light Poplar offers the same attractively grained wood as the standard Dark Poplar, but with a more subtle effect.

Bamboo wood interior trim. Another distinctive wood grain, Bamboo provides an especially distinctive and contemporary look, harmonizes well with all interior colors, and is an eco-friendly, renewable resource.

20-way front Multi-contour seats. In addition to the standard seats’ 10-way power adjustments, the 20-way power adjustments of these remarkable and comprehensive luxury seats include –

• Angle of articulated upper backrest section, independently from overall backrest angle

• Backrest width (the backrests’ side bolsters spread or narrow to accommodate the occupants’ back and shoulders)

• 4-way power lumbar support, which is standard in the 535i/xi models and 550i.

Heated rear seats, available for all models in combination with the Cold Weather Package.

BMW On-board Navigation System. The standard iDrive system has a 6.5-in. control display (color monitor) at dash center and a turn-and-push controller between the front seats. This option includes an 8.5-in., higher-resolution control display plus:

• Real Time Traffic Information, which provides up-to-the-minute information on traffic and road conditions

Head-up Display – displays important driving-related information on a 6 x 3-in. field in the windshield, just below the driver’s normal line of sight to the road ahead:

• Check Control and On-board Computer warnings, prioritized according to their urgency, such as vehicle defects, engine-oil level, low windshield-washer fluid

Logic7 premium stereo. The optional Logic7 premium audio system delivers audiophile-quality sound via a digital Surround Sound process, utilizing 13 high-quality speakers, Digital Sound Processing and increased audio power.

Sirius Satellite Radio. Appealing path to entertainment, news and information channels. After the first year of ownership, a subscription fee is required for Sirius service.

High-Definition Radio. Offers enhanced digital sound quality; FM reception becomes CD quality while AM reception becomes equivalent to analog FM reception. There are over 1,000 radio stations nationwide that currently offer high-definition broadcasts.

iPod/USB adapter. A separate USB adaptor for iPods or MP3 players, which does not use the CD changer connections, provides a convenient audio connection.

Power rear-window and manual rear side-window sunshades. For the Sedans, the option includes both; for the Sports Wagon, only the side-window shades. The power rear-window shade is controlled from a console switch; the side-window shades are easily raised or lowered by rear-seat passengers.

Update: NEW 2008 BMW 5 SERIES MAKES U.S. DEBUT IN NEW YORK
04/04/2007

Superior Power and Striking Interior Enhancements Underscore Its Sporting, Refined Character
Woodcliff Lake, NJ - April 4, 2007... The new BMW 5 Series made its North American debut at the New York International Auto Show today. A carefully refined exterior is combined with a striking enhancement of style and sophistication in the interior that underscores the sporting yet elegant and refined character of the BMW 5 Series. The interior reflects the premium character of the vehicle. High quality new materials and colors, ergonomic door panels with an optimized design, padded armrests, additional storage options and newly designed control elements all create an exceptionally refined ambience.

The diverse line-up of powerplants in the BMW 5 Series has now been enhanced by newly developed straight-six engines which offer superior power, while taking the lead in terms of fuel economy in all performance classes. The engines are mated to a choice of superb transmissions, including a six-speed manual as well as a quick and precise six-speed automatic transmission and BMW's new and unique Sport Automatic Transmission with shift paddles. The six-cylinder engine variants of the new BMW 5 Series are available with BMW xDrive permanent and variable all-wheel-drive technology.

The new BMW 5 Series also offers a wide range of innovations in driver assistance and comfort features. It is the only car in its segment available with Active Steering, BMW Night Vision, a Head-Up Display and, from now on, Active Cruise Control featuring a Stop & Go functions as well as Lane Departure Warning. Featured as standard equipment is iDrive control, with no less than six freely programmable memory buttons as well as an optionally available navigation system with voice control and full-word entry, enhancing the driving comfort of the BMW 5 Series to a new, unprecedented level.
Exterior design: sporting character with new elegance.
New highlights in design and continuing refinement have created a perfected synthesis of sporting character, elegance and lightness in both the BMW 5 Series Sedan and the BMW 5 Series Sports Wagon. In the cleanly engineered front air dam, the edging of the double kidney grille is now flush with the adjacent surfaces. The characteristically molded headlamps come with brilliant clear glass technology. Chrome edging highlights the technically sophisticated round headlamps. Another distinguishing feature is the air intake, sweeping up at the side and provided with a horizontal trim bar, highlighting the wide sporty track of the car.

The 5 Series has a sleeker, more stretched appearance on the side, an effect produced by an additional light contour along the side-sills. The rear is dominated by horizontal lines highlighting the look of superior power. Like the headlamps at the front, the rear lights also come in a new, sophisticated clear glass design and now feature LED direction indicators.

First-class style within the interior.
Enhanced control comfort, new design and particularly sophisticated materials on the surfaces give the interior of the new BMW 5 Series a new standard of quality the driver and passengers will see and feel at first sight, ensuring superb driving pleasure at all times. High-class Pearl Gloss Chrome, the comfortable padding on the armrests and center console and the two-tone finish of the door panels all reflect the new interior style. Black door trim bars and a lower panel section in the interior color take up the appearance and materials used on the dashboard. The resulting harmony of design underscores the atmosphere of relaxed comfort of the interior environment, as do the dynamic waves of the lines and forms of the door panels. The buttons for the window lifts and mirror adjustment have been integrated into the armrest, just as the handles for closing the doors have been optimized in their ergonomic design. Storage space has been increased with larger door pockets and with an open tray in the center console. The elegant and ergonomic design of the gear selector lever for the automatic transmission merges perfectly with the BMW 5 Series stylish interior.

Control of the iDrive vehicle management system has been optimized to an even higher standard. Menu guidance and graphics have been refined. Six freely programmable favorite buttons permit direct access to important functions. At the touch of a button, for example, a stored destination, a frequently dialed telephone number, or a preferred radio station can be called up.

The new BMW 5 Series will be available this month.

Woodcliff Lake, NJ – January 9, 2007…More convincingly than any other car in its class, the BMW 5 Series combines supreme style and presence with sporting power and performance. And now the design, driving experience and superior comfort offered by the 5 Series reach a new standard of perfection. Highly attractive refinements to the exterior and significant, visible and tangible enhancement of style and sophistication in the interior accentuate the sporting, elegant character of the BMW 5 Series Sedan and Sports Wagon. The premium ambience within the car’s interior is borne out by sophisticated materials, attractive colors and re-designed interior elements and controls.

Power units more muscular than before and with exceptional all-round efficiency raise the line-up of engines in the 5 Series to a higher standard. Benefiting from this kind of power, the BMW 5 Series is entering a new dimension of Efficient Dynamics attributable to a wide range of enhancements on and around the engine for maximum fuel economy and minimum emissions. A particular highlight is BMW’s innovative High Precision Injection direct fuel injection technology featured on the twin turbo straight-six power unit in the 535i models. Other new drivetrain developments are the updated, quick and precise
six-speed automatic transmission as well as BMW’s unique optional Automatic Sports Transmission with shift paddles.

Two engine variants on the new BMW 5 Series are available with BMW xDrive permanent and variable all-wheel-drive technology. In this intelligent all-wheel-drive system, optimized control and management electronics ensure spontaneous and precise response to changes in driving conditions.

The new BMW 5 Series also offers a wide range of innovations in driver assistance and comfort features. As an example, it is the only car in its segment available with Active Steering, BMW Night Vision, Head-Up Display and, new for 2008, Lane Departure Warning and Active Cruise Control featuring a Stop & Go function.

The standard iDrive control system, newly provided with six programmable memory keys, as well as an available navigation system with voice recognition, enhance the long-distance touring comfort of the BMW 5 Series.

New highlights in design and ongoing refinement ensure even greater harmony of sporting character and sophisticated elegance in the BMW 5 Series Sedan and Sports Wagon. The headlights in their characteristic look, for example, now come with new clear glass technology, transparent glass panels covering the direction indicators, and chrome surrounds highlighting the technically sophisticated character of the round headlights.

The surrounds on the BMW double kidney grille, in turn, are now flush with the surfaces on the front air dam, and the air intake sweeping up at the side along the same dynamic line as the headlight contours also contributes to the smooth, harmonious and friendly look of the front end. And last but not least, the horizontal trim bar in the middle highlights the wide track of the car and its muscular stance on the road.

An additional light contour along the side-sills gives the body of both the Sedan and Sports Wagon a sleeker, more stretched look from the side. The rear end, in turn, is dominated by horizontal lines highlighting the look of superior power. Like the headlights at the front, the rear lights also come in a new, sophisticated clear-glass look and now feature LED direction indicators. And last but certainly not least, the trim bar around the rear number plate is now defined more smoothly and precisely on the Sedan.

Enhanced control comfort, new design and particularly sophisticated materials give the interior of the new BMW 5 Series a new standard of quality the driver and passengers will see and feel at first sight. Pearl Gloss Chrome, the very pleasant rubber finish on the controls for smooth and easy handling, comfortable padding on the door armrests and panels as well as on the center console all contribute to the style and class of the interior. At the same time, additional storage options give the new BMW 5 Series an enhanced standard of practical function.

The most striking feature is the twin-tone finish on the door panels: black door trim bars at the top and the lower panel section in the interior color, together with elegantly sweeping bars, take up and continue the look and materials used on the dashboard. The buttons for window lifts and mirror adjustment have been integrated in the armrest, just as the handles for closing the doors have been optimized in their ergonomic design. The door pockets, integrated more effectively than before in the door panels, provide greater storage capacity for enhanced convenience on the road.

In its appealing look and ideal ergonomics, the new electrical gear selector lever for the automatic transmission merges perfectly into the stylish interior. Control of the iDrive vehicle management system has also been enhanced. Apart from enhanced menu guidance and refined graphics, the new programmable memory keys ensure more intuitive control and operation. These keys allow the driver and front passenger to access important functions quickly, smoothly and easily: A single button press will activate, for example, a specific destination, a frequently dialed telephone number, or a preferred radio station saved in advance.

Depending on the specific engine involved, the various models in the new BMW 5 Series come with a range of technologies and features serving to minimize fuel consumption and emissions. For example, one such technology is Brake Energy Regeneration, which concentrates the generation of electricity for the on-board network on the car’s overrun and brake phases.

Operating on-demand, the electrical coolant pump in the new BMW 5 Series 6-cylinder engines consumes significantly less power than a conventional pump and helps the engine reach its normal operating temperature earlier. The Varioserv steering assistance pump, varying the curve ring as a function of pressure and volume flow, avoids the usual increase in drive losses as a function of higher engine speeds. And when the driver and passengers do not require the air conditioning, the a/c compressor is disconnected to reduce drag forces to a minimum.

Two 6-cylinder versions will be available in the US. The powerful 535i models feature BMW’s newest inline six-cylinder engine with twin turbochargers and an intercooler for 300 incredibly flexible horsepower, thanks to high precision direct fuel injection with piezo injectors. The 528i variants feature a 230-hp 3.0-liter inline six-cylinder engine with Valvetronic technology and aluminum/magnesium construction.

The 535i models are powered by the world’s first inline six-cylinder with Twin Turbo and High Precision Direct Injection technology and an all-aluminum crankcase. Rated at 300 hp at 5,800 rpm and 300 lb-ft of torque at 1,400 – 5,000 rpm, this 3.0-liter engine offers cutting-edge performance thanks to the theories behind BMW’s Efficient Dynamics.

Using high-tech materials allows the engine to be a lightweight performer, which helps BMW achieve near 50/50 weight distribution on this and all of its vehicles. Low inertia turbocharger internals and high precision direct fuel injection makes turbo lag nearly non-existent as peak torque starts at a mere 1,400 rpm. High precision direct injection is also ideal for lean burn operation. In the lean burn mode, various intercepting layers of the fuel and air form within the combustion chamber. The fuel/air mixture is therefore particularly rich and ignitable only in the direct vicinity of the spark plug and once ignited, the flame travels to the leaner layers further from the spark plug for a clean, smooth and consistent combustion process. Redline is still an impressive 7,000 rpm and compression ratio is 10.2:1. Typical of a BMW engine are incredible smoothness, fast-revving response and refined power at all engine speeds.

The 528i models are equipped with a 3.0-liter inline six-cylinder engine that delivers 230 smooth horsepower at a peak of 6,500rpm and 200 lb-ft of torque at 2,750 rpm. Featuring BMW’s innovative Valvetronic engine system, which eliminates the conventional throttle body for throttle control, efficiency and power are available over a broader range for silky-smooth operation. The magnesium/aluminum block is a perfect example of BMW Efficient Dynamics where lightweight technology is at work and where efficiency can be felt at the accelerator pedal.

The 550i’s predecessor was widely acclaimed by most who drove or tested the 545i, not merely for its strong, fuel-efficient power, but also for its highly pleasing sound. Car and Driver (May ’04) summed it up as “among the friendliest, most enthusiastic engines in existence.“ With 4.8 liters, the 550i’s V-8 delivers even more brilliant performance. Peak power is 360 hp; peak torque is 360 lb-ft.

To further enhance performance, the optional 550i Sport Package newly includes an Aero Kit, modified-calibration Sport suspension, 19” wheels and performance tires, and a short shift lever, in addition to Multi-Contour seats with lumbar support, sport steering wheel, sport exhaust system, and Active Roll Stabilization.

As an option and, indeed, as a highly interesting alternative to the standard six-speed manual gearbox, all model variants in the BMW 5 Series are available with a six-speed automatic transmission as a no-extra-cost option.

Apart from the direct connection to the engine, this transmission stands out in particular through its upgraded hydraulics, innovative torque converter and even more powerful management software, ensuring a more spontaneous response to even the slightest movement of the gas pedal and an extremely fast and efficient gearchange. On the road, this means reaction times now some 40 per cent faster than on former automatic transmission models, with the actual gearchange time being almost halved. Shifting back a gear is now just as fast, too, thanks to the direct gear path finder.

The automatic transmission is controlled by an electronic gear selector lever following the usual gearshift pattern. The new gear selector lever moves back to its initial position once the gear selected is in mesh, with the transmission itself masterminded not in a mechanical process, but rather via electrical signals.

As an additional alternative, the optional six-speed Sport Automatic Transmission will be available in the BMW 550i and 535i equipped with the optional Sport Package. This new transmission offers the high standard of motoring comfort so typical of the latest generation of automatic transmissions and at the same time allows the driver to shift gears in even more sporting style in the manual mode, the driver choosing gears sequentially either by means of the gear selector lever introduced exclusively for this special transmission or by means of gearshift paddles on the steering wheel. The Sport Automatic will be available beginning with June 2007 production.

Standard in the BMW 5 Series, Servotronic serves to vary the degree of steering assistance as a function of road speed. At the same time, the BMW 5 Series has optionally available Active Steering, varying the steering angle in accordance with vehicle speed: with the same movement of the steering wheel, the front wheels will move further to the left and right at low speeds than at high speeds. This allows the driver to maneuver the car with less effort and force on the steering when parking, while at high speeds it is easier to remain precisely on track.

BMW’s intelligent xDrive all-wheel-drive system, available as an alternative
to standard rear-wheel drive, offers a particular experience in superior traction. Permanent and variable distribution of power provided by xDrive gives the BMW 528xi and 535xi Sedans and 535xi Sports Wagon supreme driving characteristics on a variety of terrain and driving conditions. Distributing the power of the engine via an electronically controlled multiple-plate clutch variably to all four wheels, xDrive significantly enhances the dynamic driving qualities of the Sedan and Sports Wagon. And to ensure even more precise control of the drivetrain, the DSC and xDrive computer units are now networked with one another in a new, innovative concept.

Standard on all 2008 BMW 5 Series models is Cruise Control, complete with a special braking function. Contrary to conventional cruise control, this intelligent new system is able to control the road speed of the car not just via the drag force generated by the engine and by shifting down on models with automatic transmission, but also by activating the brakes, thus keeping the car at a consistent speed when, say, driving downhill for a long distance. And using the Curve Speed Limiter, the system is also able to reduce road speed in bends whenever required for reasons of driving dynamics.

Active Cruise Control with Stop & Go offers the driver greater support and ease of motoring. This innovative system, available as an option on automatic transmission versions of the new BMW 5 Series, comes with automatic distance control enabling the driver to cruise along smoothly and conveniently on highways or country roads. The system keeps a consistent following distance from the vehicle ahead even in stop-and-go traffic at very low speeds and applying the brakes where necessary until the car reaches a standstill.

The system uses radar sensors of the latest generation with an enlarged area of vision, offering the driver a choice of four distance settings. Once the distance the driver has chosen to the vehicle ahead is no longer maintained, the system will intervene, building up brake pressure to control the car accordingly. Then, once the road ahead is free again, Active Cruise Control with Stop & Go will accelerate the car to the set speed.

This sophisticated control system is also able to reduce speed automatically to a standstill as a function of traffic conditions. In this case, Active Cruise Control with Stop & Go slows the car to a standstill and holds it in position. The maximum brake force applied by Active Cruise Control with Stop & Go is 4 meters/sec². Should the driver be required to intervene because the vehicle ahead is being decelerated very hard, the driver is warned to intervene by visual and acoustic signals.

In stop-and-go traffic, the system helps the driver by automatically maintaining the appropriate distance from the vehicle ahead, relieving the driver constantly having to apply the brakes in slow and unsmooth traffic. However, the driver still retains his responsibility, since after, for example, a short stop of more than three seconds, he is required to briefly press down the accelerator pedal or press the Resume button in order to re-accelerate the car. And even when Active Cruise Control with Stop & Go is activated, the driver is able to control the speed of his car at any time simply by giving gas or applying the brakes. Depressing the brake pedal while driving deactivates the system.

To enhance driver awareness, the new BMW 5 Series is available with a newly developed and unique assistance system helping to keep the car on course in the lane chosen by the driver. Referred to as “Lane Departure Warning”, this innovative system identifies any deviations from the correct course of the car and, if the turn signal has not been used, gives the driver a discreet but tangible vibrating signal in the steering wheel itself. The Lane Departure Warning system consists of a camera fitted near the interior mirror on the windscreen, a control unit serving to compare data, and a signaling device.

The BMW 5 Series is the only car in its segment available with a Head-Up Display. Activating this function, the driver has the benefit of receiving information and data particularly relevant for motoring directly in front of his eyes on the windscreen. As an example, the current speed of the car or navigation data is in the direct line of vision with maximum convenience at all times.

In combination with the available xenon headlights, the new BMW 5 Series comes with a daytime running light function (selectable via Vehicle memory System) using the corona rings in the dual round headlights. The headlights include Adaptive Headlight technology, illuminating the road ahead following the curves taken by the driver. In this case, the headlights swivel in accordance with the position of the steering wheel, the yaw rate of the car, and its road speed. In addition, the Cornering Light function adjusts the direction of the headlights when turning corners at less than 25 mph.

Unique in this segment, BMW Night Vision is based on a thermal imaging camera able to detect people, animals and objects, on and next to the road, up to a distance of almost 1,000 feet, transmitting a clear, high-contrast image to the Control Display.

Offering a wide range of safety and comfort features, the new BMW 5 Series makes every trip an experience in pleasure. To supplement the wide range of standard equipment, the 5 Series is available with a wide choice of high-tech audio, navigation, Bluetooth and telematic functions.

New for 2008 is an optional iPod/USB Adapter that will accommodate an iPod as well as other MP3 players, and will also allow the vehicle to be equipped with a CD changer at the same time. With this option, the driver will have full control of iPod functions and menus via the steering wheel audio controls. Other available features include HD Radio, now with multicasting reception capability, SIRIUS satellite radio, and a Navigation system that now includes Real Time Traffic Information.
