New Mercedes C-Class with efficient new engines

New Mercedes C-Class with efficient new engines

 

 

 

 
The new C-Class will be launched in spring 2011 and is a comprehensive modernisation. The front and rear sections of this best selling model have a more striking design. There is now a high-resolution colour display screen in the instrument cluster, an elegant new dashboard with grained surface and prominent decorative trim emphasising the premium character of the interior. Fuel consumption has been improved by up to 31 per cent. Efficiency-enhancing measures including new engines, the improved 7G-TRONIC PLUS automatic transmission and the ECO start/stop function also feature. Ten new driving assistance systems ranging from the standard ATTENTION ASSIST drowsiness detection system to the optional DISTRONIC PLUS proximity control system are also now available for this model series for the first time.

"In terms of drive and protection systems the new-generation C-Class offers the same comfort and safety as our luxury models.  High-grade interior features  remind one of the new CLS, the C-Class sets completely new standards in its segment with respect to perceived value and quality," says Dr. Joachim Schmidt, Sales & Marketing Director at Mercedes-Benz Cars. This interior modernisation is supplemented with a new telematics generation that not only includes completely redesigned displays, but also makes onboard internet access available.

A total of more than 2,000 new components distinguish the latest generation of the Mercedes-Benz C-Class from its predecessor. The UK market launch of the Saloon and Estate versions will take place in March 2011.

The C-Class is the highest-selling model series for Mercedes-Benz.  The current series has found well over one million buyers worldwide since its launch in March 2007 (98,000 UK sales).  Since the introduction of the first C-Class in 1982 (then known as the model 190), Mercedes-Benz has sold more than 8.5 million vehicles in total in this segment. In 2010 too, the C-Class has repeatedly won top places in the registration statistics.

Dynamic, resolute, self-assured: the exterior

The front bumper has more expressive and dynamic contours, with the front section being brought in line with the brand's new design idiom. The radiator grille surround is now more prominent. The central air intake opens out upwards in a V-shape, forming a visual base unit for the radiator grille. Pronounced side sections extend from the sporty V-shape at the centre of the bumper. Continuing beneath the headlamps, these sections blend into the feature lines along the vehicle flanks, linking the front section with the sides. The side air inlets in the bumper are positioned low down, giving the car a more road-hugging appearance.

The Saloon and Estate now have a new aluminium bonnet, which contributes to weight reduction and therefore enhances fuel efficiency. Its contour in the area of the headlamps and radiator grille emphasises the V-shape of the front section more heavily than before. In conjunction with the newly designed headlamps, this gives the front section a more resolute impression.

The shape of the clear-lens headlamps has been modified to create a more dynamic and resolute impression, and to act together with the bonnet, radiator grille and bumper to emphasise the V-shape of the front section. This impression is reinforced by both the exterior form of the headlamps and the interior of the housings. The headlamps show their modernity by precision and an interplay between matt and high-sheen areas. The halogen headlamps are arranged in the classic way, with low beam on the outside, high beam on the inside and the indicators neatly arranged in the outer corner formed with the front wing.

If the optional bi-xenon headlamps with the Intelligent Light System (ILS) are specified, the impression of depth is reinforced by a row of lighting modules. A position light with a distinctive C-shape emphasises the night design. Behind it is a cornering light extending to the main headlamp module on the outside. All three levels are connected by a transverse strip extending through the complete headlamp interior with dark contrasts, shiny areas and matt areas. A visual base in the lower section of the headlamp is formed by a horizontal broadband LED indicator unit. The horizontal LED daytime running lamps in the bumper also make the C-Class unmistakable from a distance.

In the case of the rear bumper, the light-catching contours and dividing lines have been modified to emphasise the width of the Saloon and Estate even more strongly. This change is particularly obvious in the more steeply rising course of the side light-catching contours towards the tail lights. A continuous light-catching contour at the upper end of the rear bumper extends into the flanks to connect the rear end with the sides to emphasise the sporty character of the rear aspect. In the latest model, the tail lights are even more neatly integrated into the rear section by a continuous covering lens. The characteristic surface meander is now on the inside of the light, and reminiscent of preceding model series. The particular impression of depth is achieved by a centrally located LED indicator, which appears to float in front of the red upper and lower light bands with their more deeply set LEDs. The tail lights have a particularly high recognition factor in the dark.

The aerodynamics of the C-Class are a mark of the bodyshell's efficiency. With a Cd figure of 0.26 it not only sets the benchmark in its class, but also glides through the wind better than most compact cars with its drag area of Cd x A = 0.57 sq. m.

Sporty, high-quality interior

The main focus of the design work in the interior was on restyling the dashboard with its integrated screen and new surface grain. The touch surfaces of the controls are now also more finely detailed and galvanised. A stepped extension to the instrument cluster now also accommodates the central display. The instrument cluster and a discreet light-catching contour continue into the front passenger side while the central, trapezoidal air vents and the round vents on the outside are highlighted in detail by galvanised trim.

The large section of trim is an important part of the newly designed dashboard. This extends from the centre air vents across the front passenger side to the outer air vent, while the lower edge of the upper dashboard section continues into the beltlines of the door panels with a new surface grain.

The control panel of the new-generation communication and information unit has keys with high-gloss surface inserts. The combination of keys, high-gloss areas and a new knurled wheel design accentuates the enhanced interior. In conjunction with the new generation telematics generation, the C-Class is now available with a high-resolution colour display in the instrument cluster.

More power, lower consumption: the engines

An improvement of up to 31 per cent has been achieved in fuel consumption and all C-Class launch models will feature the ECO start/stop function as standard. All the engine variants are now classed as BlueEFFICIENCY units, showing that they are particularly efficient and environmentally compatible in their use of fuel. In future all automatic versions will feature the further-developed 7G-TRONIC PLUS
seven-speed automatic transmission. In addition, the overall ratio of all new powertrain variants has been optimised for better fuel economy.

All the petrol engines in the model series have direct injection. One of the highlights is the introduction of the new V6 petrol engine with its innovative and highly efficient BlueDIRECT process in the C 350 BlueEFFICIENCY. The quantum leap in efficiency is particularly well illustrated by the six-cylinder
unit: Power has increased considerably, the C 350 BlueEFFICIENCY delivering 306 hp and 370 Nm (previously 292 hp and 365 Nm).

The four-cylinder petrol engines, which made a great evolutionary leap forward
in 2009 and all feature direct injection and turbocharging and excel with high performance and exemplary economy.

The most economical model in the Mercedes C-Class range has also become even more frugal: the C 220 CDI BlueEFFICIENCY with the manual six-speed transmission and the standard ECO start/stop function.  This corresponds to 117 grams of CO2 per kilometre. In conjunction with the improved 7G-TRONIC PLUS automatic transmission and the ECO start/stop function included as standard, the C 220 CDI BlueEFFICIENCY and C 250 CDI BlueEFFICIENCY both deliver
top-class figures with a combined diesel consumption of 58.8 mpg. This corresponds to CO2 emissions of 125 grams per kilometre.
