Mercedes-Benz C-Class: New 4MATIC generation for even better traction and driving stability

The new Mercedes-Benz C-Class: Superior safety, comfort and agility

Update: Mercedes-Benz C-Class: Available with 4MATIC all-wheel drive from the summer

Stuttgart, Apr 05, 2007
Shortly after the Europe-wide market launch of the C-Class, Mercedes-Benz has announced a further technical refinement in the new model series, namely 4MATIC permanent all-wheel drive. This further enhanced system will be available for order and delivery in the six-cylinder C 280, C 350 and C 320 CDI models from the summer of 2007. With a total of 49 4MATIC models, Mercedes-Benz will then have the widest all-wheel-drive range among all premium brands.
The latest-generation Mercedes all-wheel-drive system improves on the previous 4MATIC with greater efficiency, a lower weight and more compact dimensions. These advantages are reflected in a more favourable fuel consumption and even better traction: the new C 280 4MATIC with its 170 kW/231 hp six-cylinder engine consumes 9.6 litres of premium petrol per 100 kilometres, and is therefore more economical than its predecessor by 0.2 litres. For the first time in the C-Class, a diesel model with all-wheel drive also becomes available now: the new C 320 CDI 4MATIC has an output of 165 kW/224 hp and consumes 7.7 litres of fuel per 100 kilometres.

The 4MATIC saloons have the same, extensive safety and comfort features as the rear-wheel drive models. The AGILITY CONTROL package with selective damper control is standard equipment, as are seven airbags, crash-responsive head restraints, automatic climate control and light-alloy wheels. The seven-speed automatic transmission7G-TRONIC, which Mercedes-Benz has developed further specifically for the all-wheel-drive models, is also on board.

The 4MATIC system is permanently active, and therefore operates with no lag time, assisting the driver in unfavourable weather conditions such as rain, ice or snow, and enabling him to manage critical situations with confidence. The centrepiece of the Mercedes all-wheel-drive system is a transfer case with a centre differential, which is integrated into the seven-speed automatic transmission. From here the torque is distributed to the front and rear axles in a 45 :55 split. A newly developed multi-disc clutch on the centre differential transfers the engine power to all four wheels with a basic locking force of 50 newton metres between the front and rear axles, which means that the new C-Class moves off even more easily on slippery road surfaces, and has even more stable handling than the preceding 4MATIC models.

As a standard feature, Mercedes-Benz combines this permanent all-wheel-drive system with the Electronic Stability Program ESP® and the traction system 4ETS, which selectively brakes wheels at the onset of spin and increases the torque at the wheels which still have good traction. The system uses sensor signals to meter the automatic braking impulses which improve traction on slippery surfaces and increase stability during critical driving manoeuvres. As a result, 4ETS achieves the same effect as conventional differential locks while offering appreciably more comfort than other all-wheel-drive cars.

Stuttgart, Jan 18, 2007

Safety, comfort, agility: these are the outstanding attributes of the new C-Class. The Saloon excels with a many-faceted product concept which meets the expectations of various customer target groups. With the AVANTGARDE, ELEGANCE and CLASSIC lines, Mercedes-Benz offers three individual models whose emphasis is on either comfort or agility. All model variants share the latest, state-of-the-art technology. This includes the newly developed AGILITY CONTROL package with situation-responsive shock absorber control, the Intelligent Light System with five different lighting functions and the PRE-SAFE® preventive occupant protection system. There is a choice of four and six-cylinder engines with up to 13 percent more output than the preceding model, accompanied by up an to six percent lower fuel consumption.

With a length of 4581 millimetres, the Saloon is 55 millimetres longer than its predecessor. The body width has increased by 42 mm to 1770 millimetres, and the wheelbase by 45 mm to 2760 millimetres. These dimensions create the conditions for a generously sized interior, and therefore more comfort. The front shoulder room has increased by 40 millimetres, for example.

The design of the new C-Class is based on the modern Mercedes idiom, which reflects the technical superiority of automobiles bearing the star with taut lines and large, tranquil surfaces. The pronounced wedge-shape of the front end serves to emphasise attributes such as agility and performance. For the first time in a Mercedes salon, the radiator grille is used as a distinguishing feature to position the model variants more clearly. Three extended, horizontal louvres and a big centrally positioned Mercedes star characterise the AVANTGARDE model as a traditional design feature of sporty Mercedes models. Together with the sporty, high-quality appointments, this feature emphasises the youthful, agile appearance of this C-Class. This sporty presence can be enhanced even further with the AMG sports package, which includes striking front and rear aprons plus side skirts.

In the ELEGANCE model Mercedes-Benz employs a three-dimensional, louvred radiator grille with a high-gloss paint finish to accentuate other brand-typical attributes such as comfort and luxury. The CLASSIC model in the new C-Class is intentionally more restrained and traditional, but offers the same technical innovations as the other two model variants.

This "product-in-product" concept enables Mercedes customers to accentuate individual choices, and configure the C-Class to suit their personal taste and lifestyle even more emphatically than before. All the models offer the same, extraordinary driving experience that the Saloon provides by virtue of further technical improvements. Both by its outstanding long-distance comfort and its dynamic handling, the C-Class sets new standards in this market segment.

Shock absorbers automatically adapt to the driving situation

AGILITY CONTROL – this is the term used by Mercedes-Benz for all new and further developments that improve both comfort and agility in equal measure. This standard package includes the AGILITY CONTROL suspension, which controls the shock absorber forces according to the driving situation: when driving normally with low shock absorber impulses, the damping forces are automatically reduced for a noticeable improvement in ride comfort – but without any compromise in handling safety. When driving more dynamically, the maximum damping forces are set and the car is effectively stabilised. The AGILITY CONTROL steering of the new C-Class has a ratio of 14.5, and is therefore six percent more direct than the steering of the preceding model. The likewise included AGILITY CONTROL gearshift reflects the sporty character of the C-Class with a short travel and precise shifts.

Mercedes-Benz has also developed the ADVANCED AGILITY package with a sporty driving mode, which will become optionally available from autumn 2007. This offers the driver a choice of two gearshift programmes: Sport and Comfort. Within these programmes the shock absorber for each wheel has infinitely variable electronic control. A newly developed speed-sensitive steering with a more direct ratio, variable centring and adaptation of the accelerator characteristics and automatic transmission shift points is also included in the package.

ADAPTIVE BRAKE is another new development in the area of running gear technology. This is based on the technology of the S-Class and provides additional support functions for even more safety and comfort. Examples include Start-Off Assist for uphill gradients, priming the braking system in critical situations and light contact to dry the brake discs in wet conditions.

Output of the supercharged four-cylinder engines increased by up to 13 percent

With a remarkable boost in output by up to 13 percent and an increase of around 18 percent in torque, the engines also do more than their bit to create the lively nature of the new C-Class. The four and six-cylinder units not only excel with powerful responsiveness, but also contribute to the excellent ride comfort of the Saloon with their improved smoothness.

Mercedes-Benz has paid particular attention to further development of the four-cylinder engines. In the petrol range, the output of the entry-level C 180 KOMPRESSOR has increased from the previous 105 kW/143 hp to 115 kW/156 hp, with maximum torque improved by 4.5 percent from 220 to 230 newton metres, while the C 200 KOMPRESSOR develops 15 kW/20 hp more than before. It has an output of 135 kW/184 hp and generates its maximum torque of 250 newton metres from 2800 rpm. These modified engines considerably improve the performance and fuel consumption of the four-cylinder models. When accelerating from standstill to 100 km/h, the C 200 KOMPRESSOR is 0.5 seconds faster than its predecessor. Improvements in fuel consumption are equally impressive: the C 180 KOMPRESSOR consumes 0.3 litres per 100 kilometres less than before, while the combined fuel consumption of the C 200 KOMPRESSOR has been reduced by 0.5 litres per 100 kilometres.

Fuel consumption of the four-cylinder CDI engines reduced by 0.3 litres

Further development of the four-cylinder units was also the main focus for the diesel engines. The engineers in Stuttgart have made further improvements to the engine, turbocharger and common-rail direct injection, modifying more than 90 components. As a result of these measures the new C 200 CDI has eleven percent more output than the preceding model, with 100 kW/136 hp versus the previous 90 kW/122 hp. The C 220 CDI develops a peak output of 125 kW/170 hp (previously 110 kW/150 hp), and generates a torque of 400 newton metres from 2000 rpm - around 18 percent more than before. Fuel consumption has been reduced by up to 0.3 litres per 100 kilometres: in the New European Driving Cycle (NEDC), the C 200 CDI and C 220 CDI are able to travel 100 kilometres on just 6.1 litres of fuel.

The modern V6-engines in the C-Class range remain unchanged, with a choice of three petrol units developing 150 kW/204 hp, 170 kW/231 hp and 200 kW/272 hp. The six-cylinder of the new C 320 CDI has an output of 165 kW/224 hp. With the exception of the C 350, all models in the new C-Class are equipped with a six-speed transmission featuring AGILITY CONTROL gearshift as standard. The top-of-the-range C 350 has 7G-TRONIC, the world’s only seven-speed automatic transmission, as standard equipment. This is also available for the other six-cylinder C-Class models on request.

The latest Mercedes inventions ensure maximum safety

During the course of its development, the new C-Class successfully passed more than 100 crash tests, including the particularly demanding, in-house impact tests of which some go well beyond the legal requirements. Passing these is a precondition for the highest accolade in automobile safety: the Mercedes star. Occupant protection is based on an intelligently designed bodyshell, 70 percent of which consists of high-strength and ultra high-strength steel. Compared to the previous series, Mercedes-Benz has enlarged the deformation zones even further and improved energy flows. The front-end structure of the new C-Class has four independently acting impact levels, which enable forces to be distributed over a wide area while bypassing the passenger cell.

The safety technology in the interior has been complemented with the very latest protection systems. Seven airbags are included as standard equipment: two adaptive airbags for the driver and front passenger, a kneebag for the driver, two sidebags in the front seat backrests and two large windowbags which extend from the A to the C-pillar during a side impact. The driver, front passenger and the passengers on the outer rear seats also benefit from belt tensioners and belt force limiters as standard. The standard head restraints operate on the NECK PRO principle: during a rear-end collision the padded surfaces are pushed forward within milliseconds to support the heads of the driver and front passenger at an early stage. This significantly reduces the risk of a whiplash injury.

Mercedes-Benz has developed flashing brake lights as a major help in reducing rear-end collisions, and these are also standard equipment in the new C-Class. If the driver needs to brake hard at speeds in excess of 50 km/h, the brake lights flash rapidly to warn drivers following behind.

PRE-SAFE® is another special feature of the new Mercedes Saloon. This preventive occupant protection system (optional) is linked to active safety systems such as ESP® and Brake Assist, and is able to recognise critical driving manoeuvres at a very early stage. If the C-Class is in danger of crashing as a result of heavy under or oversteering, or if the driver needs to brake very heavily in a dangerous situation, PRE-SAFE® activates certain systems as a precaution to prepare the vehicle and its occupants for an impending accident. Accordingly the passive safety phase does not begin when the impact has already occurred, but before an impending collision.

The Intelligent Light System developed by Mercedes-Benz is also available in this vehicle class for the first time. Powerful bi-xenon headlamps provide five different lighting functions suited to typical driving and weather conditions: country mode, motorway mode, enhanced foglamps, the Active Light System and cornering lights. Yet another important contribution by Mercedes-Benz to safer driving in poor visibility.

Interior design "cast from a single mould"

When developing the cockpit, Mercedes designers took their lead from the sporty sector and included clearly laid-out dial instruments such as may be found in roadsters or coupés. Silver-coloured bezels, black dial faces, white markings and glowing orange needles perfectly combine form with function for a high value impression and easy legibility.

Equally clearly laid out and well-arranged, the two-tone dashboard and centre console of the new C-Class form a harmonious unit in line with the "design cast from a single mould" principle. The same applies to the integration of the colour display at the upper centre of the dashboard. This is perfectly positioned within the driver’s line of vision, but can also be covered or folded away as required, without switching off the radio, navigation system or other units linked to the display. If the pivoting cover of the display aperture is closed, the infotainment units continue to operate.

New control concept for clarity and comfort

The central colour display is part of the new control and display concept which the new C-Class has adopted from the luxury-class Mercedes models. Its major advantage is rapid access to frequently used functions, which means that the driver does not need to relearn, is able to maintain familiar habits and feels at home immediately. All the control and display elements necessary and important during a journey are located in the cockpit, i.e. in immediate proximity to the driver.

In the same way, linking the standard multifunction steering wheel with the instrument cluster is an important precondition for rapid access to a wide range of information and functions in the driver’s direct line of vision. Other functions such as infotainment are shown by the display at the centre of the dashboard. The driver and front passenger are able to control the radio, navigation system or telephone by using a controller on the centre console, or access the main menus using direct selection keys.

COMAND provides voice operation, a music server and DVD navigation

The Audio 20, Audio 50 APS and COMAND APS systems are a range of newly developed, optional infotainment units for C-Class passengers. They all feature a keypad for entering telephone numbers and radio frequencies, as well as a Bluetooth interface which wirelessly connects the mobile phone to the hands-free system. In the Audio 50 APS, the route guidance information – some of it as a visually attractive automatic junction zoom display - is shown by means of arrows on the fixed colour display (4.9-inch) in the dashboard. An integral 6-CD changer and the LINGUATRONIC voice control system are available on request.

The multimedia system COMAND APS offers even more functions than before in the new C-Class. One new feature is a Europe-wide navigation system whose data are stored on a hard disc (30 gigabytes). The high-resolution maps are shown on a colour display (7-inch) which pivots away and disappears beneath a cover at the touch of a button. Other functions of COMAND APS include a music server with a four-gigabyte memory, a DVD-player for video and audio, and the LINGUATRONIC voice control system, which Mercedes-Benz has likewise improved further: the driver no longer needs to spell out the names of countries, towns or roads, but is able to speak them as whole words. The voice control system is just as convenient when selecting radio stations or entries in the telephone directory.

The C-Class is the bestseller in the Mercedes lineup

The new C-Class Salon replaces a model series of which more than 1.4 million units have been sold since spring 2000. All in all, Mercedes-Benz has delivered more than two million of the Saloon, Estate and Sports Coupé models in the previous C-Class to customers all over the world. This makes the C-Class the bestseller in the Mercedes-Benz passenger car range. Germany is the largest market for the C-Class, accounting for around 30 percent of worldwide sales.

World premiere of the new Mercedes-Benz C-Class: World premiere of the new C-Class in two attractive outfits

"With the new C-Class, we are yet again raising the bar in this important segment of the market – and that's true right across the board, especially in terms of safety, comfort and agility," declared Dr. Dieter Zetsche, CEO of DaimlerChrysler AG and head of the Mercedes Car Group, at the world premiere, which was held in the Mercedes-Benz World in Stuttgart. "With its unique balance of driving characteristics, the fourth C-Class generation embodies a new driving culture in the compact premium car segment. We are thus offering our customers the most versatile and majestic C-Class of all time – and, for the first time, in two attractive outfits."

The new C-Class is the first Mercedes saloon to feature equipment lines with different faces. In the more traditional Elegance and Classic models, the star is, as before, to be found on the engine bonnet, while, in the avantgarde versions, the trademark is positioned in the centre of the radiator grille, as is typical in sporty models from Mercedes. "Starting already with the vehicle's external appearance," says Zetsche, "each customer can decide for him or herself where they want the emphasis to be." With its distinctive styling, the new premium-segment saloon offers its own unique interpretation of Mercedes-Benz's current style statement and makes the technological supremacy and quality of the new C-Class apparent at the first glance.

Alongside its renowned comfort, the traditional strengths of the C-Class include the vehicle's exemplary occupant protection. Thanks to its integrated security concept, the new model continues to lead the way in its class, with greater active safety being afforded, for example, by the adaptive braking system from the S-Class and the Intel-ligent Light System with five automatic lighting functions. A new era in safety and ergonomics is ushered in by the C-Class's innovative instrumentation and control concept, which noticeably reduces the burden on the driver and prevents him or her from being distracted.

As far as passive safety is concerned, the new C-Class meets significantly higher standards than are required around the world by the various statutory regulations. The standard equipment includes seven airbags as well as active head restraints. In addition, the new C-Class – like the large Mercedes saloons and SUVs – is also available with the PRE-SAFE® anticipatory occupant protection system.

Customers can choose from a range of state-of-the-art four- and six-cylinder petrol and diesel engines. At its market launch in the spring, the new C-Class saloon will come in three petrol-engined versions (C 200, C 280 and C 350) as well as in a four-cylinder diesel variant (C 220 CDI). In the course of the year, Mercedes-Benz will extend the available range to include, among others, the C 320 CDI V6 diesel engine as well as two four-cylinder versions, the C 180 and the C 200 CDI. The development engineers at Mercedes-Benz have focused above all on improving the popular four-cylinder engines, the outstanding qualities of which now include lower fuel consumption, higher power output and superbly smooth operation.

In Germany, despite the rise in VAT to 19 percent, the gross entry-level price for the new C-Class is still below 30,000 euros, which means that, adjusted for inflation, the price level of the new C-Class is the same as for its predecessor, over two million units of which have been sold around the world since its market launch in 2000.
