Update
THE
NEW BMW 3 SERIES (USA Press Information)
Highlights include styling updates inside & out, new technology and
the introduction of BMW Advanced Diesel with BluePerformance
Woodcliff Lake, NJ - July 16 2008... The 2009 3 Series Sedan and
Sport Wagon is poised to maintain its market leadership with updated
exterior and interior styling, new technologies, enhanced ergonomics
and, as previously announced, the U.S. introduction of BMW Advanced
Diesel with BluePerformance in the form of the 335d Sedan.
Highlights.
The new BMW 3 Series Sedans and Sports Wagons, already and always
leaders in their class, widen their lead in driving dynamics,
premium quality and innovative technology.
These vehicles combine unique BMW elegance with a driving
experience that's widely imitated, yet really inimitable.
A brand-new twin-turbo diesel engine, thoroughly BMW in its
performance and character, powers the new 335d Sedan and expands the
scope of BMW EfficientDynamics.
Subtle freshening of exterior design features a new front end,
more dynamic profile, and wider appearance at the rear. Headlights
and taillights are new, yet present a typically BMW look, innovative
lighting technology and 3-dimensional effects.
Refinement of interior design and amenities includes new colors
and materials. Overall design of interior reflects and complements
the distinctive exterior design. Among functional updates are
ergonomically enhanced placement of power-window controls for the
driver and new, expanded storage possibilities.
New generation of BMW iDrive, available in 3 Series in combination
with optional Navigation system: ergonomically optimized iDrive
controller with function selection and activation via turn, push and
tilt motions; new direct-select keys; more Programmable Memory Keys
than before. The newly enhanced Navigation system offers greater
functionality.
BMW Advanced Diesel with BluePerformance: all-new inline
6-cylinder twin-turbo diesel engine with an impressive array of new
features for high performance, high fuel efficiency and clean
exhaust. To achieve these targets, this aluminum powerplant applies
common-rail, high-pressure direct fuel injection with piezo
injectors; 2-stage turbocharging; exhaust particulates filter; and
Selective Catalytic Reduction exhaust after-treatment to reduce NOx.
Displacing 3.0 liters, this truly advanced engine enables BMW to
introduce diesel power in all 50 U.S. states; it produces 265 hp and
an amazing peak torque of 425 lb-ft.; 0-60 mph in 6.0 sec. with
6-speed automatic transmission. EPA mileage ratings have not been
finalized, but are expected to set new "mile"-stones in the
simultaneous achievement of performance with fuel economy.
Continuation of two other trailblazing BMW inline 6-cylinder
performance concepts in the other 3 Series models: the 3.0-liter
naturally aspirated unit in 328i models with weight-saving
magnesium/aluminum composite construction and Valvetronic induction
technology for 230 hp; and the 3.0-liter twin-turbocharged engine of
335i models with its direct fuel injection (piezo injectors here,
too) and large-volume dual exhaust system. This unit delivers 300
hp, and a peak torque that is remarkable not only for its quantity
(300 lb-ft.) but for the range over which it's at the driver's
disposal (1400 to 5000 rpm). Both of these gasoline engines have
been acclaimed widely for their respective qualities: for the 328i
unit, silky and strong performance with remarkable fuel economy; for
the 335i, dramatically sporty performance with fuel economy that's
notable in view of the power.
BMW's acclaimed xDrive all-wheel drive is featured in the newly
named 328i and 335i xDrive Sedans and 328i xDrive Sports Wagon. This
intelligently engineered AWD system steplessly varies the torque
split between front and rear wheels to enhance not only traction,
but also agility and stability on grippy, as well as slippery road
surfaces.
Comprehensive safety concept with extremely rigid body structure;
carefully defined "force paths" that lead and distribute collision
forces optimally through the structure; targeted application of
high-strength steels and deformation elements; six airbags including
front side-impact and front/rear head protection; new Active front
head restraints.
The 2009 models are: 328i Sedan and Sports Wagon; 328i xDrive
Sedan and Sports Wagon; 335i, 335i xDrive and 335d Sedans. The 3
Series also encompasses Coupes and retractable-hardtop Convertibles;
these continue with less extensive updates for 2009.
Segment original remains segment leader.
The BMW 3 Series is an internationally recognized symbol of the
intelligently sporty motor vehicle. It is also the best-selling
premium vehicle in the world. Updates for the 2009 Sedan and Sports
Wagon models include -
A subtle exterior-design freshening
Refinement of interior design and functions
New and/or revised options
A new generation of the iDrive control and display system
Expansion of ConnectedDrive functions
An all-new turbodiesel engine in a new model - the 335d Sedan.
Fundamentally unchanged - and still not successfully challenged in
other quarters - are the Series' essential attributes of rear-(or
all-)wheel drive, harmonious front/rear weight balance,
outstandingly precise steering and skillfully engineered
suspension
all of which conspire to produce the uniquely satisfying
driving experience that is quintessentially BMW.
And, more than ever, this inimitable driving experience in
combination with growing attention to fuel efficiency and
environmental consciousness. Thanks to the various facets of BMW
EfficientDynamics - especially via the new turbodiesel-powered 335d
Sedan - the BMW experience is more satisfying than ever before.
New design accents for greater sportiness and elegance.
The new Sedans are distinguished by a freshened design at the front,
in profile and in the rear view; the new Sports Wagons receive the
same front-end and profile updates, as well as most elements of the
rearview changes.
At the front, width is more strongly accented, though actual width
is unchanged. BMW's traditional 4-headlight look is emphasized by
the lamps' setting in new chromed "tubes;" the more recently
traditional luminous rings around the headlights newly serve as
Daytime Running Lamps on vehicles with Xenon Adaptive lights
(optional 328i models, standard 335i models). The turn-signal lamps
get a new, vertically layered look; in combination with the Xenon
headlights these are in LED technology.
In profile, the side sills/rocker panels set a stronger lower
accent; newly shaped side mirrors not only have crisp new contours,
but also provide an enlarged visual field for the driver.
At the rear, the bumper, taillights and (on the Sedans) trunklid are
all newly shaped for a stronger emphasis on the 3's sporty
character. The taillights' typical L-shape is now more in evidence,
and new LED lighting sources illuminate the taillights and
turn-signal lamps. And an actual increase in rear track adds new
emphasis to these vehicles' wide stance in rear and Ύ views.
Interior: high-quality materials, enhanced ergonomics and a
new-generation iDrive system.
Subtle updates to materials and surface textures make the 3 Series
interior even more attractive; refinement of interior design and
amenities include enhanced placement of power-window controls for
driver and new, expanded storage possibilities.
In the 3 Series, BMW's iDrive control and display system is included
in the Navigation option. As in the new 7 Series (where iDrive and
Navigation are standard), a 2nd generation of iDrive sets new
standards for ergonomics, efficiency and logical functionality with
its new, higher-definition, 8.8-in. Control Display. More uniformly
structured menus, and an optimized control strategy for the display
and console-mounted controller are also signature new features.
Other new details include keys for direct selection of the Radio,
CD, Navigation and Telecommunications menus, grouped conveniently
next to the controller. Visual assists and consistent hierarchies in
the display simplify choices within the individual menus. In the
Navigation section, users will experience a new and superior level
of brilliance, detail and variability of map displays. A "map
preview" function facilitates selection of the navigation
destination from a list; in a new operational logic, letters of the
alphabet and numerals are arranged in circular form for more
intuitive input of addresses and phone numbers.
Hard drive for audio and Navigation data storage.
Newly included in the Navigation option is a hard drive for storage
of Navigation data (such as destinations) and audio material (such
as music). The large capacity hard drive means quick access, and
allows transfer of material from a CD, MP3 player or a USB stick to
the hard drive, which can hold up to 8-GB of music.
BMW Assist: expanded capabilities
As a dynamically evolving array of valuable functions, the new 3
incorporates BMW Assist and TeleService functions (both included in
the BMW Assist option). Automatic emergency calling, a long-standing
standard feature of the BMW Assist telematics scheme, is
meaningfully enhanced in the new 3: In the event of a collision of a
certain severity, the system transmits to the BMW Call Center the
vehicle's location and specifications, as well as data from several
onboard sensors that define the type of collision and probability of
occupant injury. At the same time, the Call Center attempts to
establish a voice connection with the vehicle occupants and deploys
emergency services as appropriate.
BMW Advanced Diesel with BluePerformance: high-performance,
high-efficiency twin-turbo diesel engine in the 335d Sedan.
As an important element of BMW EfficientDynamics, the new 335d Sedan
represents a significant step forward in combining high performance
with high fuel efficiency. The 3.0-liter, twin-turbocharged inline
6-cylinder diesel engine powering the 335d - its predecessor has
been widely acclaimed in Europe - is completely new to the U.S. also
new is its BMW BluePerformance emission-control technology.
Among the turbodiesel engine's advanced attributes are aluminum
construction, high-pressure direct fuel injection with piezo
injectors (also a feature of BMW's twin-turbo gasoline engines), and
a turbocharging system that employs both a small and larger
turbocharger for optimum response at low and higher speeds.
As a worldwide advance also being newly introduced in Europe, BMW
BluePerformance controls emissions to a strict level that enables
the 335d to be sold in all 50 U.S. states. Specific features of this
system include an exhaust particulates filter and a Selective
Catalytic Reduction exhaust after-treatment system.
Given the stringent emission control and fuel economy that will
truly raise eyebrows (official EPA mileage ratings are not yet
available), one might expect performance to suffer. On the contrary:
this new power concept achieves not only abundant power (265 hp,
0-60 mph in 6.0 seconds with the standard 6-speed automatic
transmission), but immense torque (425 lb-ft.) that gives the 335d
all-speed acceleration response that simply has to be experienced to
be believed. And - a quality of smoothness and sound that fully
lives up to the BMW reputation for sonorous power.
Gasoline-powered 3 Series models: continuing the BMW tradition of
smoothness, great sound and outstanding fuel efficiency.
All other 3 Series models continue with their (also) acclaimed
3.0-liter inline 6-cylinder gasoline engines.
The 328i models are powered by a naturally aspirated (i.e.,
non-turbo) engine that features advanced, weight-saving
magnesium/aluminum construction - still unique among the world's
automobiles. Its Valvetronic system enhances efficiency by employing
variable valve lift, rather than a throttle, to regulate engine
power. This engine produces 230 hp, 200 lb-ft. of torque, and EPA
highway mileage ratings as high as 28 mpg (depending on model and
transmission) in 2008. It is a sterling example of BMW's
long-standing tradition of the smooth, sonically delightful "inline
six" that delivers excellent performance.
For those who desire more than merely excellent performance, the
335i models are powered by a completely distinct 3.0-liter six,
boosted by twin turbochargers and fed with fuel by High Precision
direct fuel injection. This unique and highly advanced unit delivers
300 hp and 300 lb-ft. of torque, 0-60-mph times as quick as 5.4
sec., and EPA highway mileage ratings up to 26 mpg. If the 328i
engine has been enthusiastically acclaimed, the 335i unit has
garnered downright deliriously praise, particularly by the
automotive enthusiast media.
Intelligent all-wheel drive in the 3 Series: the xDrive models.
Continuing for '09 are the two Sedan models and one Sports Wagon
model with BMW's truly intelligent AWD system, now taking the
system's name into their model designations: 328i xDrive Sedan and
Sports Wagon, 335i xDrive Sedan. The Coupe models also have xDrive.
At the core of this permanent AWD system is an electronically
controlled multi-disc clutch that steplessly varies torque
distribution between the front and rear wheels, and does so with
near-instantaneous speed. xDrive doesn't just optimize traction; it
can also enhance both agility and stability on grippy as well as
slippery road surfaces..
Superlative chassis technology; Active Steering optional on 335i
models.
Part and parcel of BMW's tradition as The Ultimate Driving Machine
is sophisticated chassis technology. All 3 Series models have BMW's
patented double-pivot strut-type front suspension with aluminum
components on rear-wheel drive models for reduced unsprung weight.
The rear suspension is a 5-link system engineered for a unique
combination of agility and reassuring stability.
BMW's steering is just as essential to the driving experience. All 3
Series models come standard with a hydraulic power-steering system
whose road feel and precision are legendary; optional on 335i Sedans
is Active Steering, which varies both the steering ratio and power
assist to further enhance agility, particularly at low to medium
driving speeds. Active Steering is another of those BMW innovations
that truly has to be experienced to be believed.
Optimized occupant protection: including new Active head restraints
on the front seats.
The 3 Series safety concept is based on a solid and rigid body
structure that utilizes high-strength steels and targeted
deformation elements to channel and absorb collision forces in the
most effective way for crash safety. Specific safety equipment and
systems include 3-point safety belts and adjustable head restraints
at all (five) seating positions. LATCH attachments for child safety
seats are standard at the outboard rear seating positions.
New for 2009 are Active front head restraints, which in a rear-end
impact employ fast-acting pyrotechnic activation to pivot the
restraints' forward portion into close proximity with the occupants'
heads: the head restraint, or headrest, moves up to 60 mm/2.4 in.
forward and 40 mm/1.6 in. upward. This reduces their heads' rearward
motion, lessening the likelihood of whiplash or other head/neck
injuries.
Standard airbag equipment in all current 3 Series Sedans and Sports
Wagons includes 2-stage, optimally configured front-impact airbags;
front-seat side-impact airbags; and a front-to-rear, curtain-type
Head Protection system deployed from the interior ceiling.
Advanced forward illumination contributes to active safety.
A significant contribution to active safety, that is the avoidance
of accidents, is Xenon Adaptive headlight technology, standard on
335i/335d models and optional on 328i models. In addition to the
greater luminous power of Xenon lights, Adaptive means that the
headlights "steer" with the front wheels, governed by the vehicle's
speed and the "yaw rate" at which its direction is changing. This
occurs at all speeds and is especially beneficial at speed on
curving rural roads at night.
Newly included on Sedans and Wagons with the Adaptive headlights are
Cornering Lights, which direct an angled beam at each front corner
to assist in situations of low speed and sharp turns. Additionally,
on U.S. models both of these lamps illuminate when reverse gear is
engaged. Also included is auto-leveling, which maintains accurate
aiming with changing vehicle loading, acceleration and braking to
reduce glare to oncoming motorists.
Class-leading automatic climate control.
BMW's automatic climate control provides both effective automatic
operation and a high degree of manual "override" control when
desired. The 3 Series system is of recent design that incorporates
highly refined airflow that is both high-volume and quiet. Fuzzy
logic assists in effective temperature regulation, separately for
the driver and passenger sides. Other features include
activated-charcoal microfilter ventilation; temperature- and
volume-controlled air to the rear passenger compartment; a
bi-directional solar sensor to account for solar effects; automatic
air recirculation when excessive air pollution is sensed; automatic
reduction of blower speed when the vehicle comes to a stop; and a
misting sensor that detects windshield fogging and adjusts system
operation to clear it up.
The design: unique, unmistakable, elegant.
Subtle new details accent 3 Series' dynamic character.
New headlights, taillights and side sills.
Even better ergonomics and esthetics inside.
The current 3 Series, already strong on BMW dynamism and identity,
now gains an additional measure of both by virtue of discreet
updates and refinements. At the rear, a widened track enhances these
vehicles' planted-on-the-road stance; careful and subtle
modifications to the front, sides and aft end make the total design
even more harmonious.
At the front. A new, bolder front spoiler/bumper ensemble imparts
sportier, stronger character. Its center air intake is larger than
before, enhancing the air supply for mechanical components; upswept
lines in the lower air intakes, the bumper itself and the newly
shaped headlight clusters emphasize the wide stance. Double
longitudinal hood lines, more 3-dimensional than ever, rise toward
the A-pillars and frame the hood's power dome. New lighting features
include the layered turn-signal lenses, and on models with Xenon
Adaptive headlights, BMW's distinctive luminous rings now serve as
Daytime Running Lamps (on all models, they also function as parking
lights). The optional Park Distance Control now includes front and
rear monitoring.; formerly PDC was offered on the 3 Series in a
rear-only version.
In profile. The lower character line that runs from just behind the
front wheel well to just ahead of the rear wheel well, is more
prominently contoured and strongly expresses the low stance. On
Sport Package-equipped models, new high-gloss Shadowline (black)
trim more elegantly frames the side windows. And new wheel designs
freshen the 328i models' 16-in. and the 335i/335d models' 17-in.
standard equipment.
At the rear. Restating BMW's traditional L-form are the taillight
clusters of both Sedan and Sports Wagon models. Their two main
segments, for the taillights and turn signals, are composed of LED
rows for an even higher-tech look than before. On Sedans, the
trunklid is newly shaped to go with the new taillight design. And
the 0.6-in.-wider rear track does its part to strengthen an already
road-gripping stance.
New colors. BMW paint colors are notable for their richness and
eye-catching appeal. A total of 12 colors are offered with three new
metallics for '09: Space Gray, Tasman Green and Blue Water.
Interior: newly refined materials, surfaces and colors. Here too,
subtle updates and refinements mark the newest 3 Series Sedan and
Sports Wagon interiors. Materials and surface quality add appeal;
certain functional elements including the optional iDrive controller
and climate and audio controls offer refined appearance and tactile
qualities.
The doorsill trims with their distinctive BMW script are new. The
somewhat smaller iDrive controller has a fine galvanic surface, and
is newly surrounded by the direct-select keys that enhance iDrive's
user-friendliness. There's a larger storage tray in the center
console including the auxiliary audio input and providing an
appropriate place to lay an audio source. Door-panel design has been
refined too; on the driver's door the power-window and -mirror
controls have been moved 2 cm rearward for an easier, more natural
reach.
Colors and color contrasts have been improved, as well. Three new
colors for the optional Dakota leather upholstery are offered:
Oyster, Saddle Brown and Chestnut Brown. Interior trim choices are
updated, too, with a new Fine Line aluminum trim replacing the
former brushed aluminum and Light Burl Walnut replacing Light Poplar
among the available wood trims.
Lastly, a heated steering wheel - much appreciated by drivers of
other BMW Series in winter weather - has been added to the optional
Cold Weather Package for all models.
In general, the interior space - with its attractive interplay of
convex and concave surfaces, its sporty elegance and
technology-oriented esthetics is more appealing than ever.
BMW Efficient Dynamics in the new 3 Series: BMW Advanced Diesel with
Blue Performance meets emission standards in all 50 states.
New inline 6-cylinder twin-turbo diesel engine in 335d Sedan.
BluePerformance technology meets diesel-engine emission standards
in all 50 U.S. states.
In its competitive field, BMW is known for powertrains that achieve
an outstanding combination of performance and fuel efficiency. In
addition to the commendable mileage ratings of the 3 Series'
gasoline engines, the newest evidence of BMW's EfficientDynamics
approach is the new twin-turbo diesel engine of the likewise new
335d Sedan model, which combines the new-age diesel performance that
has swept European motoring in recent years with truly remarkable
Miles per Gallon.
The new 335d Sedan: power, torque and remarkable fuel efficiency.
All with refinement and sound worthy of a BMW.
In Europe, where fuel prices have historically been - and remain -
much higher than in the U.S., vehicle manufacturers have achieved
dramatic gains in the performance, smoothness, quietness and
emission control of diesel engines
while maintaining the diesel's
historic superiority in fuel efficiency. Now, with the new 335d
Sedan, BMW brings this progress to the U.S., with brand-new
technology that meets the U.S.' strictest emission standards.
Like all '09 BMW gasoline engines, the 335d's new diesel is
constructed with a weight-saving aluminum cylinder block - something
that's not taken for granted given the diesel's much higher
compression pressures. (All BMW engines have aluminum cylinder
heads.) It is an inline 6-cylinder engine maintaining a defining BMW
tradition that means exceptional smoothness and unique sound.
In addition, several diesel-specific technologies of this new engine
contribute to its achievement of true high performance, diesel fuel
economy and clean exhaust:
Common-rail direct fuel injection. One of the most important
innovations of recent diesel development, this has replaced the
individual-cylinder or distributor-type injection systems of earlier
diesel engines.
Common Rail (CR) means that a single, very high-pressure
fuel-delivery pump supplies all cylinders, the fuel traveling along
a common "rail" or distributor line. From there, fuel is injected at
extremely high pressure (180 bar/2645 lb./sq in.) directly into the
cylinder.
The basic novelty of common-rail injection was to divorce the
production of fuel pressure from the actual injection process; this
was necessary to give the diesel engine what gasoline engines have
long had, namely completely electronically controlled fuel
injection. CR also facilitates multiple injections per combustion
cycle. In all, this was a breakthrough that made possible dramatic
strides in diesel power, efficiency and emission control.
Piezo injectors. A further breakthrough, already applied by BMW in
the 335i (and other BMWs) models' twin-turbo gasoline engines. With
direct injection, the injectors - that critical component injecting
fuel into each cylinder's combustion chamber - are subject to
especially high temperatures and pressures. Instead of most
injectors' conventional electrical valves, a "stack" of piezo
crystals reacts lighting-fast to impulses from the engine
electronics governing the injector needle's opening stroke and
duration for ultra-precise control. This, too, facilitates major
advances in fuel economy and emission control, in gasoline, as well
as diesel engines.
Variable Twin Turbo technology. In contrast to the two small,
equal-size turbochargers of BMW's twin-turbo 6-cylinder and V-8
engines, the diesel employs two turbos of different sizes.
At low engine speeds, intake air does pass through the large turbo,
but it's the smaller, lower-inertia one that does the air
compressing (turbocharging). Thanks to its optimum efficiency within
this rpm range, it provides effective boost for driving from a
standstill up to modest acceleration rates and driving speeds. So it
is that this engine develops a good 390 lb-ft. of torque at as low
as 1500 rpm - a remarkable achievement that will amaze first-time
335d drivers and continue to thrill those who drive this BMW
regularly.
With increasing engine speed, the larger turbocharger begins to take
over: first as a pre-compressor for the smaller one, then
progressively until it becomes the primary turbo. The engine reaches
its maximum of 425 lb-ft. by 1750 rpm, then maintains this immense
torque level until 2250 rpm going on to reach its peak power of 265
hp at 4200 rpm.
Diesel combustion, power and torque characteristics. In its most
basic distinction from gasoline engines, a diesel engine achieves
its combustion not with a sparkplug, but by much "harder"
compression of the fuel-air mixture; the 335d engine, for example,
has a compression ratio of 16:5:1, vs. 12.0:1 in today's
ultra-high-performance BMW M gasoline engines and the 10.2:1 of the
335i twin-turbo gasoline unit. For one thing, this requires a
significantly stronger engine structure; indeed, the 335d engine
weighs more than its 335i counterpart.
The diesel combustion process also produces very different torque
and power characteristics. Whereas the 335i engine reaches a maximum
torque of 300 lb-ft. @ 1400-5000 rpm and a maximum power of 300 hp @
5800 rpm, the 335d attains its maximum torque of 425 lb-ft. @
1750-2250 rpm and its maximum power of 265 hp @ just 4200 rpm. In
general, diesels have this low-speed-torque, lower-rpm character and
in their vehicular application, they are geared differently. The
335d, for example, comes only with automatic transmission - an
automatic is the ideal partner for a diesel engine - and its final
drive ratio is 2.81:1, vs. 3.46:1 for the 335i with automatic
transmission.
Diesel engines also employ a different fuel, the product of a
different refining process from that of gasoline. The two fuels are
not interchangeable; gasoline cannot be used in a diesel engine, and
vice versa. Their prices typically diverge; at any time or in any
location, demand may be different for the two, and government
taxation policies for gasoline and diesel fuel also diverge.
Stellar pulling moxie, full-bore acceleration - and fuel efficiency.
The huge torque output of 425 lb-ft. at relatively low engine speeds
speaks for itself; 335d drivers will marvel at this engine's robust
response at low to medium speeds. The peak power output of 265 hp
also speaks for itself, as does the resulting 0-60-mph time of 6.0
sec. While official EPA mileage estimates are not yet available,
preliminary tests indicate 23 mpg city and 33 highway.
Most advanced exhaust gas management: SCR catalyst with AdBlue
injection.
BMW Advanced Diesel with BluePerformance optimizes emission
management by incorporating an oxidation catalyst placed close to
the engine, a diesel particulate filter housed in the same unit, and
an SCR catalyst with urea injection. Apart from filtering out even
the smallest particles from the flow of exhaust gases, this
combination ensures effective reduction of nitric oxides (NOX) by
way of a chemical reaction within the exhaust system initiated by
the injection of a small dose of urea referred to as AdBlue. The
ammonia (NH3) generated in this process within the SCR catalyst
subsequently converts the nitric oxides (NO and, respectively, NO2)
in the exhaust gas into environmentally compatible nitrogen (N2) and
vapor (H2O).
BMW has developed a two-tank system for AdBlue ensuring convenient
use of this new technology with all the benefits and ease required
by the customer: The amount of AdBlue required in each case is drawn
from the active tank comprising approximately 1.6 gallons by means
of a dosage pump. And since the urea solution would freeze at a
temperature of ?11oC, this active tank, as well as the dosage pipes
are heated.
AdBlue technology by BMW: reduced emissions without additional
service appointments.
The active tank is connected to a second reservoir, the so-called
passive tank. With its additional capacity of approximately 4.5
gallons, this passive tank offers a plentiful supply of the urea
solution required within the car. The average range provided on this
supply capacity is indeed sufficient to have the tank system
replenished as part of normal scheduled maintenance.
From the active tank AdBlue is delivered to the dosing valve and
atomized into the exhaust emissions. Consistent distribution of
AdBlue within the flow of exhaust emissions is ensured by the SCR
mixer. The ammonia generated in this way in the hot emission gas
subsequently acts in the SCR catalyst as a reduction agent and
converts environmentally harmful nitric oxides into nitrogen and
water vapor in a process referred to as selective catalytic
reduction.
This process gives the special SCR catalyst its name with the SCR
system as such being masterminded by highly efficient engine
management. A nitric oxide sensor, finally, provides information on
the concentration of NOX in the exhaust emissions.
The large amount of AdBlue provided in the reservoir enables the
customer to go on driving as before without having to change service
intervals or observe any particular requirements, thus benefiting
from the advantages of this environmentally friendly emission
technology throughout the entire running life of the car without any
additional service or visits to the workshop. During the first four
years or 50,000 miles, the replenishment of AdBlue will be covered
as part of the BMW Scheduled Maintenance program: not only will
there be no additional inconvenience, but no addition cost during
that period.
Other 3 Series powertrains: smooth, strong and efficient 6-cylinder
gasoline engines, diverse transmission choices.
328i and 335i models powered by two distinct inline 6-cylinder
engines.
Dynamic performance in the great BMW tradition.
Many transmission choices, all with 6 speeds.
Two quite distinct inline 6-cylinder gasoline engines power all
other 3 Series models; these remain unchanged in the new '09 models.
328i models: 3.0-liter inline 6-cylinder engine, naturally
aspirated.
In the 328i models - Sedan and Sports Wagon, rear-wheel- and
all-wheel-drive models - a 3.0-liter unit with advanced,
weight-saving magnesium/aluminum composite construction and
Valvetronic variable valve lift provides smooth, sonorous and
fuel-efficient power.
Valvetronic, a patented BMW innovation, varies valve lift to
regulate engine power; when the driver steps down on the accelerator
pedal, instead of a throttle opening wider, intake-valve lift
increases. A throttle imposes a restriction to incoming air;
Valvetronic eliminates this restriction, significantly enhancing
efficiency particularly at low to medium speeds. This is reflected
in excellent fuel economy, plus very spontaneous response to that
accelerator pedal. Valvetronic also enhances engine smoothness in
idling and gentle driving, and makes for excellent cold starting.
This engine delivers 230 hp @ 6500 rpm and has a 7000-rpm redline,
so it is in the great tradition of smooth, powerful and high-revving
BMW gasoline engines. Yet its torque peak of 200 lb-ft. occurs at
relatively low engine speed for a gasoline engine - 2750 rpm - so
it's also a responsive partner in everyday driving, not requiring
frequent shifting to maintain a brisk pace with the standard 6-speed
manual transmission. 0-60-mph times for the 328i Sedan are 6.3 sec.
for the manual, 6.9 sec. for the automatic; 2008 EPA city/highway
mileage ratings are 18/28 mpg with manual, 19/28 with automatic.
Acceleration times and EPA ratings vary for the Sports Wagon, and
for the Sedan and Sports Wagon in their xDrive (all-wheel-drive)
versions.
335i models: also 3.0-liter inline 6, twin-turbo, even more
brilliant performance.
The 335i Sedan and its AWD stablemate 335i xDrive are powered by a
totally distinct 3.0-liter inline 6, with an aluminum block,
different bore and stroke dimensions, and most importantly twin
turbochargers. High-pressure direct fuel injection with piezo
injectors, a concept shared with the 335d diesel engine, and special
turbo-related cooling features complete the description of an engine
that has garnered almost delirious praise in the enthusiast media
and beyond. It develops a full 300 hp @ 5800 rpm, has the same
7000-rpm redline as the 328i engine, and generates a fulsome 300
lb-ft. of torque all the way from 1400 to 5000 rpm - a somewhat
diesel-like characteristic.
Here the twin turbochargers are both small, each of them serving 3
of the 6 cylinders. Their smallness enables them to respond quickly
to the driver's demands reducing turbo engines' historical "turbo
lag" to a minimum. This engine does not have Valvetronic, as
turbocharging works best on a gasoline engine with a conventional
throttle. On-the-road performance is stunning: 0-60 mph in just 5.4
sec. with manual transmission, 5.6 with automatic; and that broad,
generous torque band produces abundant acceleration even at lower
speeds in the upper gears. EPA mileage ratings are equally
impressive: 17/26 mpg with either transmission for the 335i,
slightly less for the xDrive version.
Transmission choices: 6-speed manual or automatic, shift paddles
optional.
All 3 Series transmission choices are 6-speeds. The manual gearbox,
standard on all models, is engineered to provide what buyers want
when they choose it: precise control and a high level of driving
pleasure.
BMW also places a high priority on active driving pleasure with its
automatic transmissions. Recent refinements to the 3 Series'
automatics have improved their sportiness, precision and efficiency:
a torque converter that slips less, quicker shifting, finer
adaptation to driving style and conditions. All BMW automatics
include a Sport mode that quickens shifting and holds the lower
gears longer; and a Manual mode that allows the driver to take
charge of virtually all shifting.
Steering-wheel-mounted shift paddles are added on all automatic 3
Series models with the Sport Package, and include a Direct Selection
feature: When the driver is motoring along in Drive and makes a
shift via paddle, the transmission goes into the Manual mode.
BMW iDrive, 2nd generation: new graphics and controls.
New controller concept, high-resolution 8.8-in. control display.
Optimized menu structures, high-resolution graphics, expanded
range of functions.
Greater convenience and more intuitive operation via direct-select
keys at the controller, plus more Programmable Memory Keys.
In the 3 Series, BMW's iDrive system of controls and displays is
offered in combination with the optional Navigation system. In the
new 3 Series Sedans and Sports Wagons, iDrive enters its 2nd
generation building upon this pioneering development, while making
it more natural, more intuitive, simpler and more elegant in its
functionality - and more esthetically pleasing and enjoyable. In
offering this new generation of iDrive, the
3 Series joins the new 7 Series that is also being introduced this
autumn.
More intuitive operation, expanded functions.
With the 2002 7 Series, BMW initiated a new direction in the control
of vehicle features and functions; via a multi-menu color display
and a mouse-like controller usable by driver and passenger alike, a
potentially crowded landscape of buttons and knobs was supplanted by
a computer-logic control path.
An overarching attribute of iDrive was the separation of control
(via the console controller) and display (the centrally placed
iDrive monitor). This basic arrangement remains; the controller has
been further developed and the display has evolved markedly.
Positioned centrally in the instrument panel, the new control
display sets higher standards for logical, readily understood menus
and attractive graphics. The controller has been refined for
comfortable, intuitive selection and activation of functions via
standardized turn, push and tilt motions, while being augmented with
new direct-selection keys for specific menus, plus more of the
Programmable Memory Keys that were added to the system in the 3
Series in 2007-08.
Greater functionality, satisfying to use: controller with
direct-selection keys.
Benefiting from the newest biomechanics R&D, the state-of-the-art
controller operates with tactile precision and clearly structured
motions. New control elements, menu schemes and graphic
representations in the control display become evident upon first
use, yet user appreciation grows over the longer term. A graphic
depiction of the controller in the display itself helps orient the
user to the next control step; the rotation, pressing and tipping
motions generally correspond to those of a computer mouse.
Thus interpreted, rotation of the controller takes the user through
menu selections; pressing it makes the choice. Tilting the
controller to the left or right effects navigation through various
menu levels. Via clear graphic organization in the form of stacked
layers and onscreen depiction of controller movements, the user
enjoys highly intuitive navigation. All menus are structured
according to a consistent scheme, so that one is almost immediately
at ease; menus are broad so that the user can view relatively
numerous options without switching to another level. Also, functions
are arranged so that in longer-term use the most important options
are reached more rapidly.
An additional new refinement is four direct-selection keys, placed
adjacent to the controller, for the most frequently used menus.
These allow quick selection of CD, radio, phone and navigation
menus, and are augmented by three further keys of general utility:
one takes the user directly to the start menu (MENU), one to the
most recently active menu (BACK), and the third (OPTION) presents
various options within the current area. Thus searches are likely to
be shorter, or unnecessary.
Familiar and proven, yet now more useful: Programmable Memory Keys.
An iDrive enhancement recently introduced in various BMW models
represents a further user convenience: Programmable Memory Keys.
When first introduced, there were six of them; now there are eight.
Lined up above the audio controls, these allow the user to capture
and store favorite or frequently used functions (radio stations,
phone numbers, navigation destinations for example) on various keys
and recall them instantly. The stored functions can be as specific
and detailed as a navigation map in the preferred scale or an audio
balance setting. And because the keys are sensitive not just to
being pressed but also to being merely touched, one can see the
stored function on the control display by lightly touching the key.
If it's the right one, the user need only press the key and it's
there, ready to use.
High-resolution display, preview maps and full-screen images.
With its 8.8-in., high-resolution monitor, the new iDrive displays
remarkably attractive images. It's a system appropriate to the
vehicle it's in, achieved via up-to-date hard- and software.
White-on-black menu lists; effective symbols and icons; contemporary
graphics; and clear, consistent color-coding are among the elements
that enhance not only function but also esthetics.
Menu structures, too, make finding desired functions easier. In the
Start Menu, all functional areas served by iDrive are listed.
Selecting a given item leads to its menu layer, where the options of
that level are also listed. This consistency in navigation assists
in orienting the user, as does the "stacking" of menu layers in the
display. Visual assists further contribute to clarity. And if the
user gets to a place where he or she didn't mean to be, the Back key
usually reverses the error.
User-friendlier Navigation.
This overall refinement of functionality means simpler and more
enjoyable use of the optional Navigation. Full-screen map displays
offer outstandingly detailed views of the geography; maps as well as
specific symbols can be shown in 3-dimensional form. Selected points
of interest along the travel route appear with near-photographic
realism.
Mere input of destinations reveals the new system's impressive
capabilities. If the destination appears on a list in the system, a
preview map appears as the user scrolls the list; this can help
distinguish between places with similar or identical names. If a
destination (or a phone number) needs to be entered manually, this
is done with a new, circular "speller" that makes the entry go more
quickly.
Convenient combination of voice entry and controller operation.
Yet, another iDrive innovation is its ability to combine voice and
controller entry called Multi-mode Input. The user can go back and
forth between the two methods, while actually inputting; indeed,
voice recognition can remain active during input via controller and
the user can modify an input via voice. Voice recognition - BMW
calls it Voice Command - is activated by its function key on the
steering wheel, and de-activated either upon completion of the
action or by pressing the key again. Voice Command is simplified by
visual display of the available commands, yet its capabilities go
further in that numerous synonyms of these commands are also
recognized.
This newly enhanced iDrive introduces a very significant step
forward in the operation of automotive features and functions.
Greater efficiency, improved logic and clear, attractive displays
help define and advance the 3 Series' unique product character. The
new iDrive helps the freshened 3 Series Sedans and Sports Wagons
create a user experience that is truly unique.
BMW Assist: networking for greater convenience, safety and security.
Intelligent networking of driver, vehicle and driving environment.
Expanded range of services and capabilities.
BMW pioneered Navigation as an automotive feature in 1994, for the
first time bringing data from outside the vehicle into the driver's
cabin. In 2002, the 7 Series introduced iDrive integrating GPS
Navigation into a more comprehensive grouping of vehicular functions
and capabilities. For 2009, this evolution continues with
introduction of the 2nd-generation iDrive, further development of
the Navigation system's potentials and an expanded range of
telematics services within the BMW Assist system.
In its most fundamental precepts, BMW Assist emphasizes "warning and
serving, not intervening." The driver (or more generally, user)
retains the responsibility for his or her vehicle. It lightens the
user's burdens by offering as much information and assistance as the
user desires in each specific situation.
BMW Assist: telematics enhance users' convenience, safety and
security.
BMW Assist safety and convenience services are offered as the BMW
Assist Safety Plan (standard with BMW Assist) and Convenience Plan
(an option expanding BMW Assist). The Safety Plan is in effect for
the first 4 years or 50,000 miles from new and includes the
following services:
Automatic Collision Notification. In the event of an airbag
deployment or severe impact, the BMW Call Center is notified and
emergency services are deployed as appropriate. New for '09: if the
collision is of a certain severity or worse, the system transmits
the vehicle's location and specifications, as well as data from
several onboard sensors that define the type of collision and
probability of occupant injury.
Emergency Request. Vehicle occupants may request emergency services
24/7 by pressing the SOS button.
Enhanced Roadside Assistance may also be summoned from the vehicle
in a similar manner. Adds features and services beyond the
4-year/unlimited-miles Roadside Assistance that is standard with
every current BMW model.
Remote Vehicle Unlock from the Call Center when the user gets locked
out.
Stolen Vehicle Recovery. The user files a police report and notifies
the Call Center, which can remotely activate the BMW Assist system
to locate the vehicle and help police recover it.
TeleService automatically transmits key vehicle data to the
subscriber's preferred BMW center when the vehicle's Condition-Based
Service sensors detect a need for upcoming service; in turn the BMW
Center contacts the owner. The driver can also initiate a service
request.
Customer Relations. Users can speak with BMW Customer Relations at
the push of a button.
The Convenience Plan, optional on a yearly basis, expands these
services by offering:
Directions, traffic and weather information.
Critical Calling. If the subscriber forgets to bring a mobile phone
or its battery is discharged, yet urgently needs to make a phone
call, four operator-assisted calls per year via the SOS button are
included.
Concierge Service including travel planning, dining and hotel
reservations, shopping assistance and event tickets.
There are additional services for vehicles equipped with the
Navigation system:
Real Time Traffic Information is received in the vehicle via an FM
data broadcast. It is processed in the system to notify the driver
of potential traffic problems on the programmed route, and offers an
alternate route or the option of automatic re-routing around the
problem. RTTI is available in more than 50 metropolitan markets in
the U.S; BMW provides it to customers for a minimum of 4 years
without recurring monthly bills.
Expanded Navigation capabilities. The new 2nd-generation iDrive
system incorporates many enhancements to Navigation capabilities.
Among these are directions to change lanes or make a turn at an
obscured intersection, 3-dimensional screens depicting topography
along the route and selected points of interest.
Bluetooth cellphone interface included with BMW Assist option. When
a BMW-approved cellphone is paired with the interface, BMW's
in-vehicle hands-free memory, dialing and calling features are
available to users. Voice Command, included with the Navigation
option, enables phone (and other) functions to be voice-activated.
In keeping with BMW's policy of accommodating contemporary
technological products and the evolving lifestyles that go with
them, the latest iPhone models are among the approved BMW cellphones.
BMW xDrive: intelligent all-wheel drive that's infinitely variable,
satisfying agile, always reassuring.
BMW is the world's most successful producer of premium vehicles
with all-wheel drive.
Now smoother and more precise than ever, thanks to modulated brake
intervention and torque compensation.
Available in three Sedan and Sports Wagon models, plus two Coupe
models.
Increasingly, customers - particularly those who drive in snowy
winter conditions - want all-wheel drive. In the 3 Series, five
models - with new "xDrive" model designations - incorporate BMW's
unique and advanced AWD system of the same name.
This permanent, electronically controlled system varies the split
between front- and rear-wheel driving torque according to driving
conditions to produce an incomparable degree of comfort, traction
and agility. Via a smooth, precisely controlled central multi-disc
clutch, it directs torque to the wheels where the traction is best,
reacting amazingly quickly to each change in driving conditions.
In most normal driving situations, xDrive apportions 40% of the
driving torque to the front wheels, 60% to the rear to provide a
typical BMW rear-wheel-drive handling feel. Sensors continuously and
sensitively monitor the four wheels, detecting even the tiniest
amount of slip; torque distribution adjusts in fractions of a second
to match changing conditions. It all occurs so quickly, in fact,
that the system almost seems to be anticipating slip; the driver is
unlikely to perceive the need to adjust the torque split before
xDrive accomplishes it.
Enhancing xDrive's quick and precise action is the networking of
xDrive and Dynamic Stability Control, the traction and stability
system that's standard on all BMW models. As part of BMW's overall
Integrated Chassis Management (ICM), this powerful and capable
networking helps calibrate xDrive torque distribution and other
chassis functions to instantaneous conditions. Thus xDrive and DSC
react to varying road traction or abrupt steering, braking or
acceleration by the driver, always endowing the vehicle with optimum
stability and agility.
Via ICM, xDrive and DSC detect any incipient excessive over- or
understeer, adjusting the front/rear torque split to avoid these
tendencies. If undesirable oversteer is sensed, the multi-disc
clutch is completely closed, sending the maximum possible torque to
the front wheels. If excessive understeer is detected, xDrive opens
the clutch completely, sending all the torque to the rear wheels. In
true BMW tradition, the driver enjoys optimum vehicle dynamics under
a wide range of driving and road conditions. Finely dosed
application of individual wheel brakes compensates for side-to-side
traction variations, as well: this aspect of DSC was improved upon
the current 3 Series' introduction, via new analog brake actuation
in this situation, as well as other stability-related or anti-lock
brake interventions.
An illustrious history: from pioneering sports sedan to world leader
in its class.
1975: a new vehicle category is born.
Unending progress: BMW 3 Series as cutting edge.
Over five generations, always the benchmark.
Strictly speaking, the 3 Series' chronicle begins in March 1966,
when the BMW 1600-2 was introduced at the Geneva Salon (automobile
show). That was the launch of the smallest BMW of the time, a
compact 2-door sedan with a bit of coupe character, BMW's
front-engine/rear-drive layout and a definite sporting flavor. When
a larger, 2.0-liter engine was installed, the model that captured
the imagination of enthusiast in the U.S., the 2002 was born. The
actual 3 Series designation made its debut in the U.S. in 1976 -
when the 2002 was succeeded by an all-new 2-door.
Over five generations, the 3 Series has always remained true to the
values set by the 2002: a compact, sporty, maneuverable, stylish and
nicely powered automobile - that was also practical for everyday
transportation for at least four persons. Yet, this Series has
nurtured another role: that of the cutting edge of automotive
progress and the benchmark of what has become an established market
segment. A segment, by the way, that didn't exist then; the 1600-2
and 3 Series created it.
1st generation: the 3 Series was a true Original.
That 1st-generation 3 Series, offered in the U.S. from 1976 through
1983 as the 320i, was offered elsewhere first with four, then later
five different engines. In the U.S. 320i with a 2.0-liter motor,
that was later updated with a smaller but more advanced 1.8-liter
4-cyinder engine. In Europe, the crowning version was the 323i
introducing the Series' first 6-cylinder engine and heralding a new
era in compact, yet sophisticated and powerful sports sedans.
2nd generation: model proliferation brings many choices.
Offered in the U.S. from 1983 into 1994, the 2nd generation began as
a discreet, but thorough updating of the 1st-generation 2-door (but
soon added the first 4-door body in the Series). At the same time,
the first 6-cylinder 3 Series U.S. models appeared with the 325e,
powered by an enlarged (2.7-liter) version of the 323i's 2.3-liter
six, specifically engineered for high fuel economy. Other variations
included a convertible and an all-wheel-drive system; eventually the
325e and its variants were replaced by smaller-engine (2.5-liter),
yet higher-performance 325i models. "s" versions of both were
offered in North America giving the Series' sporty image a boost.
3rd generation: a "big leap" in design.
This generation debuted here in the U.S. in 1991 and was offered
into 2000. It looked much more different from its predecessor than
had the 2nd from the 1st; conceived with greater comfort and safety
in mind, it was also significantly larger. 4- and 6-cylinder engines
were offered ranging over time all the way to 2.8 liters and 190 hp.
With a long hood and its cabin set farther back, the 2-door became a
true coupe. The convertible became a mainstay of the Series, and the
Compact, offered as 318ti in the U.S., was developed to extend the
Series' price range downward. This version of the 3 Series first
appeared on Car and Driver Magazine's10Best list in 1992. The 3
Series would go on to appear on every list since then, a feat
achieved by no other car.
4th generation: the 3 Series struts its stuff.
This time the styling evolution reverted to gentle; the 4th
generation updated its predecessor's design theme, but aimed it
elegantly toward the 21st century. Production began in 1998 and
continued through 2006: 4-door sedans came first, then coupes,
convertibles and the first 3 Series sports wagon to be offered in
the U.S. As another
3 Series first, this generation was offered only with 6-cylinder
engines from beginning to end growing from the initial 2.8 liters to
3.0.
Another strong trend took shape as the Series acquired higher levels
of luxury and electronic driving assists: antilock braking, traction
control and eventually stability control became standard. BMW's
pioneering Head Protection System also made its 3 Series debut with
this generation. Vehicle and Key Memory introduced the concept of
variable, customer-selected functions, while new options such as
Xenon headlights, Navigation and the STEPTRONIC automatic
transmission enhanced the driving experience and maintained the
Series' innovation role.
5th generation: bringing the Series up to today.
The Geneva Salon of 2005 saw the debut of today's 3 Series
generation. As usual the 4-door sedans came first; soon after the
sedans made their U.S. debut as '06 models, they were joined by the
sports wagon. This was another more dramatic design step,
accompanied by a revolutionary new engine: with the
magnesium/aluminum composite construction that continues in the
newest 328i models. Yet, another innovation followed shortly: the
xDrive all-wheel-drive system, replacing the mechanical concept of
earlier BMW AWD systems with fully electronic control.
Other significant innovations included aluminum front suspension,
new braking functions within the DSC system, Active Steering and
Active Cruise Control. iDrive also appeared in the 3 for the first
time, in combination with the Navigation option, as it continues to
be today. When the new coupes were introduced for '07, they brought
with them an innovation under the hood: the world's first
twin-turbocharged inline 6-cylinder engine in the 335i Coupe.
And shortly, thereafter, came another first for BMW: the 3 Series'
retractable-hardtop Convertible models with the magnesium/aluminum
naturally aspirated engine (328i), and the twin-turbo engine (335i).
Today's Sedans, Coupes and Convertibles continue with this choice of
engines, while U.S. Sports Wagon models are offered only as 328i.
It's a story of focus, care, adherence to clear values - a
consistent vision of quality and a sporting yet practical driving
and ownership experience. The latest round of 3 Series evolution and
improvement, described in this release, is a validation and
continuation of this story.
THE ALL NEW
2007 BMW 3 SERIES COUPE
Continuing a
Tradition of Elegance & Performance
Update: New Photographs of BMW 3 Series!
Woodcliff
Lake, NJ August 7, 2006
Since the earliest days of the company, BMW Coupes
have been elegant expressions of individual style and passion for
driving.
By the
1930's, a coupe was widely appreciated as a special automobile for
people who regarded automobiles as much more than convenient
transportation. The BMW 327 Coupe, introduced in 1938, was widely
regarded as a truly outstanding example of that viewpoint and
remains a legend to this day.
With
totally new looks and thrilling performance, the all-new BMW Coupe
once again sets the benchmark for elegant design, luxury and value.
In true BMW tradition, it also establishes new standards of
performance and driving dynamics with the introduction of an
exceptional engine: the first inline six-cylinder engine with
twin-turbochargers, high precision fuel injection, and an
all-aluminum crankcase.
The
performance potential of the new 300 horsepower turbocharged engine
ensures that the 335i Coupe delivers a significant improvement in
performance while maintaining the efficiency for which the BMW 3
Series is renowned. The 335i Coupe will be joined in the U.S. by
the 230 horsepower 328i Coupe.
An
additional dimension of driving dynamics with the benefit of
outstanding traction is available in the 328xi, the first time BMW's
xDrive all-wheel drive has been offered on a
3 Series Coupe. BMW xDrive is the most sophisticated and responsive
all-wheel drive system on the market. It has proven its merits, in
terms of agility and safety, in the ten BMW models currently offered
with xDrive in the U.S.
In
addition to the standard six-speed manual transmission, both models
will be offered with an available six-speed
STEPTRONIC
automatic
transmission. Designed for responsiveness, the new automatic
enhances driving dynamics without sacrificing fuel efficiency.
The
distinctive character of the newest BMW Coupe, internally-designated
E92, is recognizable from the very first glance. Over and above the
basic shape of the car and its classic lines, the graphic design of
the headlights, the detail of the taillights, the interior and even
the exterior mirrors were specifically created for the new Coupe.
These unique design elements reflect the special character of this
elegant and sporty new car. The driver who chooses a Coupe wants a
car with elegant looks as well as driving dynamics. With all this
in mind, BMW engineers and designers set out to create a unique yet
unmistakable blend of design, features and - most importantly -
driving pleasure.
more photos below
Designed to
reflect the performance and elegance in the tradition of BMW Coupes
The new
Coupe is unquestionably a BMW 3 Series. Yet despite its close
technical ties to the Sedan and Sports Wagon, it is unique in its
design details. A genuine BMW from every angle, the Coupe is an
individualist through and through.
It's all
about proportions. The Coupe's long hood reflects BMW's adherence
to its tradition of inline six-cylinder engines. The long
wheelbase, short overhangs, the passenger compartment set back and
the low, sleek roofline which seamlessly slopes into the trunk are
all characteristics of BMW Coupes.
In
addition to the classic proportions, three design lines - the
shoulder, character and sill lines - serve to enhance the sleek
appearance. Both the shoulder line and character line stretch
uninterrupted to the back of the car, allowing one's eye to move
quickly and smoothly from front to rear along the entire length of
the car. The sill line of the lower edge of the door flows into the
front and rear air dams, reinforcing the dynamic nature of BMW's
newest Coupe.
The
combination of lines flowing into one another elegantly emphasizes
the Coupe's performance potential. While the shoulder line rises
slightly but consistently from front to rear, the character line
flows in a long, stretched arch all the way from the front fender to
the taillights. As the sill line, by contrast, moves up slightly to
the rear in a slow and gentle curve, the distance between the
character and sill lines becomes smaller near the rear wheel arches.
The fender flare around each rear wheel also serves to give the
character line extra tension in both an upward and outward
direction.
The front
view also shows a significant distinction from the 3 Series Sedan
and Sports Wagon. The contours of the hood as well as the design of
the front air dam and headlights give the new BMW 3 Series Coupe a
particularly low and sporty look. The powerdome on the hood alludes
to the exhilarating driving experience that awaits. Its lines form
a powerful silhouette extending all the way from the A-pillars to
the outside corners of the BMW kidney grille.
The
kidney grille, a traditional feature of every BMW, stands out from
the surfaces around it. Interaction with the three-dimensional
kidney frame creates a look of power and unique style.
The
headlight units on the new BMW 3 Series Coupe also have a unique
look. With the hood extending beyond the headlights as such, they
appear to have been sliced-off at the top creating a sense of
powerful, concentrated focus.
The new 3
Series Coupe will come standard in the U.S. with xenon adaptive
headlights, accented by BMW's corona light rings. The corona light
rings can not only serve as daytime running lights (if that feature
is selected via the Vehicle & Key Memory System), but also draw
attention to BMW's characteristic four round headlights, making the
new Coupe instantly recognizable as a BMW, day or night.
The
design of the taillights is also unique to the new 3 Series Coupe.
Integrated flush into the body of the car, the lights are split
into two sections and extend up the trunk lid, blending with the
character lines from the side profile. Horizontal LED taillights
give the car an unmistakable look at night. The horizontal flowing
lines accentuate the wide track and low stance of the new Coupe.
The
designers' objective was to give the new 3 Series Coupe a balanced
and harmonious look. The traditional "Hofmeister kink" at the
bottom edge of the C-pillar now extends at an even more distinct
angle into the shoulder line. To further accentuate this flow of
lines, the window accent surround is now made in one single piece.
The
exterior mirrors have been specifically designed and matched to the
unique character of the 3 Series Coupe. The contours of the mirrors
reflect the profile lines while the mirrors blend with the car's
overall design.
A cabin
befitting a BMW Coupe
The
emphasis on individual style, dynamic performance and exclusivity
continues within the interior. Here again, the focus is on the
driving experience. Horizontal lines dominate the surfaces on and
around the instrument panel which blend with the lines of the center
console door panels to give the interior a light but dynamic feel.
In true BMW fashion, all
operational and informational elements essential to driving are
grouped on and around the steering wheel.
Climate controls, as well as those for the audio and navigation
systems, are within easy reach of the front passenger.
Because
the new Coupe is a four passenger car, the rear seat passengers are
treated to a center console between their individual rear seats
which includes individual storage boxes, additional air outlet vents
and footwell lights.
The new
BMW 3 Series Coupe comes standard with Dark Burl Walnut wood trim.
As on other 3 Series models, Light Poplar wood and Brushed Aluminum
trim are optional and Gray Poplar wood, similar to the 5 Series'
Maple Anthracite, is a new choice. All these trim choices are
no-extra-cost options. Like the standard Walnut, these materials
appear on the dash, front and rear consoles, doors and rear side
panels.
The
standard leatherette upholstery is available in Black and new Creme
Beige, which is lighter then the familiar Sand Beige. For the
optional leather upholstery, the softer and more luxurious Dakota
grade replaces the previous Montana grade as in the 3 Series Sedans
and Sports Wagons. Here too, Creme Beige replaces Sand and there
are two new choices, Coral Red (as in the 5 Series) and Saddle
Brown, in addition to Gray and Black. Upholstery leather appears on
the seat facings, door inserts and door handle surrounds; other
leather-trimmed items include the gear shift boot, handbrake grip
and steering wheel.
In other
items of trim that don't change with upholstery or trim options, the
interior door handles, gearshift surround trim, steering wheel
spokes, instrument dial and engine Start/Stop button surrounds, dash
air-outlet adjusting tabs and the optional iDrive controller are in
pearl-gray galvanic material; climate-control knobs receive the same
improvements as in Z4s (galvanic trim and rubber grip surfaces of
finer tactile quality). Another trim material, called Titanium
Light, appears in several accent locations on the dashboard, center
console and doors.
An
elegant ambiance is further created in the interior by special
lighting and switches with a premium look and feel. Ambiance
Lighting, streaming down from under the ledge on the door and side
panels, and running from the A pillar all the way to the rear
passenger area, creates a particularly warm, indirect lighting
effect.
Through
its design and configuration, the cabin emphasizes the sporting and
driver-oriented character of BMW's new Coupe. Taking a seat behind
the steering wheel, the driver will immediately focus on the new
instrument cluster which includes an oil temperature gauge
positioned below the tachometer.
Buckling
up has never been easier for the driver and front passenger because
of the newly developed belt feeder arm: The seat belt integrated in
the B-pillar, moved rearward in typical coupe fashion, is
automatically "delivered" to the driver and front passenger once
they close their respective door and the key has been inserted in
the ignition slot. Connected to the seat occupancy detector, the
passenger-side belt feeder arm is only activated when the front
passenger has actually taken a seat. With the belt delivery unit
housed conveniently within the side panels, this new system does not
impair the elegant look of the interior.
Access to
the two seats in the rear has been made even easier; the lever for
releasing the seat positioners is fitted at the top of the outside
of the backrest.
Inline
six-cylinder engines enter new dimensions of performance
The new
BMW 3 Series Coupe will arrive in the U.S. with the choice of two
six-cylinder engines including an uprated version of the powerplant
in the 2006 325i and 325xi Sedans and Sports Wagon and the world's
first inline six with twin turbos, high precision fuel injection,
and an all-aluminum crankcase.
The 328Ci
Coupe is powered by BMW's N52 3.0 liter inline six-cylinder engine,
with horsepower increased to 230. Its magnesium/aluminum
construction and Valvetronic variable valve lift are features found
only on BMW engines. Compared to the M54 engine family of the new 3
Series Coupe's predecessors, the N52 achieves impressive progress on
all fronts.
The new
engine has more power: 230 hp vs. 184 hp, greater torque: 200 lb-ft.
vs. 175, and torque characteristics across the broad range of engine
speeds. Its "red line" is 7000 rpm compared to 6500 for the M54.
The new
N52 weighs 22lb. less than its predecessor. Had BMW engineers
developed the previous engine to meet their goals, it would have
added approximately 30lb. - and thus would have weighed 52lb. more
than the new engine does. Because there is just one external drive
belt, compared to the previous two, overall engine length is about
an inch shorter.
An
aluminum/magnesium engine block exclusive to BMW, hollow camshafts,
plastic camshaft cover, improved combustion chambers, a further
evolved Double VANOS,
higher fuel injection pressure, all-new engine electronics, an
electric coolant pump, a variable-volume oil pump and an oil/coolant
heat exchanger are the other weight-saving features and improvements
of the new engine.
BMW's other
approach to modern 6-cylinder power
It is the
most powerful engine within BMW's wide range of inline-six driving
machines that does not wear an "M" badge. This brand-new engine,
designated N54, develops a maximum output of 300hp in U.S.
specifications from 3.0 liters displacement and generates peak
torque of 300 lb-ft for powerful acceleration in any situation. And
it achieves these results using technology that might surprise
students of BMW history: turbocharging.
Although
it is standard equipment on BMWs highly acclaimed diesel engines,
BMW has not used turbocharging with a road-going gasoline powerplant
since the 1980's. Until now, the BMW 745i Sedan, which debuted in
1981, and the iconic BMW 2002 Turbo, introduced at the 1973
Frankfurt auto show, were the only two standard production,
gasoline-powered BMWs to employ the technology.
While the
technology works as advertised, BMW engineers were not satisfied
with the most often-cited downside to turbocharging; the frustrating
lag between when the driver presses the accelerator pedal and when
the turbocharger develops sufficient rotation to increase power.
This lag is at its worst at low engine speeds. Other drawbacks
included relatively high fuel consumption and available materials
did not always fare well under the high-heat, high-rpm operation of
the turbocharger, which gets its energy from hot, flowing exhaust
gases and typically spins up to 5-figure rpm's. For these and other
reasons, BMW put turbocharged gasoline engines on the shelf for more
than 20 years.
Two
recent developments caused BMW to reconsider turbocharging: a trend
among many luxury-performance carmakers to achieve power gains by
building engines of ever-increasing displacement and technology
transfer from turbocharged diesel engine development to their
gasoline-fired counterparts.
Accordingly, BMW recently articulated its new approach to developing
high-performance engines as part of its EfficientDynamics
initiative. Beginning with the N52 normally aspirated engine and
the N54 turbocharged unit, BMW will achieve its performance goals
with smaller, lighter, more efficient and cleaner-running engines.
The all-new N54 features twin,
relatively small turbochargers to boost performance significantly,
but, at the same time, minimize the response lag. Thanks to their
lower inertia, two small turbochargers build up pressure much faster
than a single, large turbocharger, thus eliminating even the
slightest lag.
The front
turbocharger feeds cylinders 1-3; the rear unit delivers
super-compressed air to cylinders 4-6.
A further
advantage of turbocharging is that this is the most weight-efficient
method to boost engine power and performance. The N54 turbocharged
inline 6 weighs approximately 150 lbs. less than an equally powerful
eight-cylinder engine displacing 4.0 liters. This lower weight
means a significant advantage not only in fuel economy, but also in
balancing the car's weight distribution.
To
enhance efficiency to an even higher level, the turbochargers are
made of a particularly heat-resistant material which makes them
immune to high exhaust gas temperatures in the interest of a
fuel-efficient combustion process particularly under full load.
As a
result, the twin turbo technology in the BMW 335i Coupe represents a
significant achievement in terms of both performance and fuel
economy. The advantages over a conventional turbocharged engine are
not only clearly measurable, but easy to feel on the road.
This new
high-performance engine gives the light, aerodynamically sculpted
Coupe outstanding acceleration and flexibility. The twin turbo
powerplant in the BMW 335i Coupe develops its power and performance
much more spontaneously than a turbocharged engine of conventional
design.
At the
same time the new engine offers all the smoothness and refinement
which made BMW's award-winning inline sixes so admired. Last but
certainly not least, the impressive increase in power on the twin
turbo engine versus a conventional normally aspirated six-cylinder
engine comes without any significant increase in fuel consumption.
Turbocharging typically includes intercooling of the engine's
induction air, that is, cooling the compressed air that emerges,
very much heated up by the compression process, from the
turbocharger(s). Sometimes it's done with coolant; in the case of
the N54 engine, it's accomplished with outside air. Intercooling is
desirable, often necessary, to reduce the temperature of the
incoming air to 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, is equipped with
knock control.
As
effective as the magnesium/aluminum engine construction is for
saving weight, the significantly increased loads and cylinder
pressures of the N54 300-hp engine required the use of an aluminum
engine structure with cast-iron cylinder sleeves. Of course, some,
but not all, of the N52's magnesium/aluminum weight saving was
lost. Altogether, the N54 weighs 419 lb.; the N52 357.
A new
high-precision direct fuel injection system with piezo injectors
also enhances performance and fuel efficiency. A 2nd-generation
evolution of the system found on the 760's V12 engine, it is a key
factor in achieving BMW's goals for this engine. The new system's
main advance over its predecessor is that it provides the engineers
a greater degree of freedom in the calibration of fuel quantity and
timing and the distribution of the fuel-air mixture in the
combustion chamber.
A piezo
injector, a recent advancement in fuel injector technology, uses an
actuator that takes the place of the solenoid valve in a
conventional injector. The actuator, which works significantly
faster than the solenoid, significantly reduces the injector's
response time. That results in, according to researchers who led
the piezo injector's development, a 2-3% fuel savings and 20% less
emissions.
For the
first time in a 3 Series model, the 335i Coupe's dual exhaust system
runs at both sides of the vehicle - logical, as each contains its
own turbocharger turbine and therefore requires extra space. At low
loads, a flap channels most gas through one side to reduce
low-frequency exhaust "rumble." The 335i Coupe features an
air-to-oil external oil cooler mounted in one wheel well as opposed
to the N52's coolant-to-oil unit.
The peak
power of 300 hp has already been mentioned; this is fully 45 more
than the 2006 330i Sedan and 70 hp up on the new 328i Coupe. At
least as important is the fact that this engine can deliver its peak
torque from 1400 rpm - not far above idling - to 5000 rpm. On the
road, this power and torque result in outstanding performance. The
335i Coupe with manual transmission accelerates from 0 - 60 mph in
just 5.3 seconds. This sense of urgency continues all the way to
the electronically limited top speed of 150 mph when equipped with
the optional Sport Package.
A
transmission for any driving style
As in the
3 Series Sedans and Sports Wagons, each new Coupe has as standard
equipment a 6-speed manual transmission specifically tailored to its
performance capability. In the 328i, it is a Getrag Type I, with
the same ratios as in the 2006 325i Sedan - with relatively "short"
1st-, 2nd- and 3rd-gear ratios to enhance acceleration.
The 328xi
has the heavier-duty Getrag Type H transmission, with slightly
different ratios, not for performance or economy reasons, but
because of internal design factors.
Because
of its performance potential, the 335i is fitted with the still more
robust
ZF Type G gearbox, but with "taller" 1st-4th ratios that take
advantage of the N54 engine's torque and allow this high-performance
model to attain higher speeds in each of these ratios. This effect
is furthered by the 335i's numerically lower final drive ratio (335i
3.08:1, 328i 3.23:1).
In all
three transmissions, 5th gear is direct (1.00:1), and 6th gear is an
overdrive for quietness and fuel efficiency at cruising speeds. All
3 Series manual transmissions offer several tangible benefits:
-
Highly effective synchronization of shifting
-
Light, pleasing feel as the shift lever is moved from gear to
gear
-
Sporty shifting, via short shift "throws" from neutral to each
gear
-
Use
of lifetime transmission oil, which never needs to be changed
-
"Clean bearings" design; protects bearings from contamination,
ensures adequate lubrication at all times and therefore enhances
durability.
The new 3
Series Coupe now joins other BMW Series in offering the 6-speed
STEPTRONIC
automatic
transmission. Compared to the 5-speed unit it replaces, it's
lighter, has a more effective torque converter, operates with fewer
internal clutches, and can reduce fuel consumption, particularly at
cruising speeds when 6th gear is in frequent use. In the 335i, and
to appear in other models later, the automatic is the familiar ZF 6
HP 19, but in the new TU, or Technically Updated, form.
As in all
other current BMW automatics, the
STEPTRONIC
feature
offers drivers a choice of Normal, Sport and Manual modes. Park,
Reverse, Neutral and Drive ranges (P-R-N-D) are in the right gate of
the shift lever. The Sport mode, in which shifts occur at higher
engine speeds, is engaged by moving the lever leftward from D; the
Manual mode is engaged when the driver manually chooses a gear by
tipping the lever (or shift paddles) forward (for downshifts) or
rearward (for upshifts).
Compared
to the existing ZF 6 HP 19, as found in 2006 model year 3 Series
Sedans and Sports Wagons, the TU has significant improvements:
-
More effective damping
of torsional vibrations in the torque converter, which have made
it possible to keep the converter's lockup engaged more of the
time. This means less slippage; the resulting fuel economy
improvement is about 3%, and the driver experiences sharper
response to the accelerator pedal.
-
Quicker shifting response
to the driver's performance demands - up to 40% quicker. This
is satisfying to the driver, who experiences less lag between
the time the accelerator pedal is depressed and the shift lever
(or shift paddles) moved and the actual occurrence of a shift.
-
Quicker shifts.
Once
a shift is actually initiated, the time it takes to complete the
shift is reduced up to 50%. This was accomplished via a new
hydraulic shifting system and more sophisticated electronic
software.
-
Finer adaptation
to driving style and conditions. Within the Adaptive shift
control, which adjusts shift characteristics to these variables,
there are now three stages vs. the previous two.
This
transmission has two additional features, both of which enhance
enthusiastic driving:
-
Direct selection of Manual mode. If,
while driving in D, the driver manually downshifts via paddle or
shift lever, the Manual mode engages. But if the driver makes
no further manual shifts within 15 seconds, the transmission
returns to automatic operation. This feature was first
introduced on the '06 Z4 Roadsters and Coupes.
-
Shift paddles on steering wheel,
offered on the 335i only as a stand-alone option with the Sport
Package. There are two paddles above the steering wheel's
horizontal spokes. Similar to the shift lever, tipping the
paddles rearward produces an upshift; tipping forward produces a
downshift.
xDrive:
BMW's first Coupe with all-wheel drive
Like the
other all-wheel drive BMWs, the new 328xi Coupe incorporates BMW's
advanced xDrive all-wheel drive and traction system. xDrive
operates as follows:
-
Driving torque is always transmitted to the rear wheels, and
most of the time, to all four wheels.
-
The
portion of torque transmitted to the front wheels is controlled
by a multi-disc clutch that can be fully open, fully engaged or
at any level of partial engagement in between. The torque split
between the rear and front wheels is thus steplessly variable.
-
Engagement pressure on the multi-disc clutch is directed by an
electronic control system in response to actual road and driving
conditions.
xDrive
doesn't just optimize traction; it can also enhance both agility and
stability on grippy as well as slippery road surfaces. Via the same
type of logic that DSC employs to recognize and correct for
excessive over-or understeer, xDrive adjusts the front/rear torque
split to avoid these tendencies. If undesirable oversteer is
sensed, the multi-disc clutch is completely closed, sending the
maximum possible torque to the front wheels. If excessive
understeer is detected, xDrive opens the clutch completely sending
no driving torque to the front wheels. In the BMW tradition, the
driver ensures optimum vehicle dynamics under a wide range of
driving and road conditions.
In a
comparison test of BMW 3 Series, Mercedes-Benz C-Class and Subaru
Legacy all-wheel drive models, Germany's authoritative auto motor
und sport magazine had this to say about xDrive:
"The BMW
330xi has the most modern and adaptable concept. It works: With
amazing aplomb, the 3 Series moves right ahead in knee-deep snow,
and keeps its front and rear ends smartly under control. Where in
other vehicles the driver may break out in a cold sweat on snowy
roads, he or she can keep cool in the 3."
Traditional
BMW driving dynamics further refined
The new 3
Series Coupe offers class-leading agility through a combination of
its significantly enhanced dynamic potential on the one hand and
with the most sophisticated chassis control and assistance systems
on the other. Together they provide a margin of safety for any
situation in which a car might reach the limits of driving physics.
In other words, the driver and passengers in a BMW 3 Series Coupe
enjoy superior active safety at all speeds.
Traditional rear-wheel drive and a near 50:50 front-to-rear weight
distribution give the new BMW 3 Series Coupe ideal qualities for
optimum driving dynamics. The specially tuned suspension enables
the driver to convert the power and performance of the engine into
an exhilarating driving experience. Boasting a new double-pivot
front suspension with spring struts made almost entirely of aluminum
in combination with a new five-link rear suspension, the new BMW 3
Series Coupe has the most advanced and sophisticated suspension in
its class.
Although
the new 3 Series Coupe's double-pivot front suspension it is already
familiar from the 5, 6 and 7 Series, the current 3 Series Sedans and
Sports Wagons introduced this system to the 3 Series in '06 and the
3 Series Coupes incorporate it for the first time. It is a more
elaborate concept than that of the predecessor models, featuring two
lower arms working in combination with the spring/shock absorber
strut. The previous, highly acclaimed, 3 Series system utilizes a
single, curved arm. These two lower arms are the reason for the
name "double-pivot."
By
employing two lower arms, the system provides several fundamental
advantages:
