Mercedes A-class - emissions from just 99 g of CO2/km

05 March 2012

 

 

 

 

 
The heartbeat of a new generation: at the centre of Mercedes-Benz's presence at the Geneva Motor Show will be the world premiere of the new A-Class. The company is opening up a whole new chapter in the compact segment: markedly emotive in design, with powerful engines ranging from 109 hp to 211 hp, and extremely efficient, with emissions from just 99 g of CO2/km. At the same time the new model underlines that for Mercedes-Benz safety is not a question of price - the standard specification includes, amongst other things, the radar-based COLLISION PREVENTION ASSIST system. 

"A is for Attack: the A-Class is a clear statement of the new dynamism of the Mercedes-Benz brand," explains Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars. "It is completely new, down to the last detail. In automotive development, it's not often you get the chance to start with a clean sheet of paper. Our engineers and designers have made the very most of that opportunity."

Design and dynamism are obvious characteristics of the new A-Class even at first glance, simply in the way it sits up to 18 centimetres closer to the road than its predecessor. The radical new design idiom that was so enthusiastically received upon its first appearance with the "Concept A-CLASS" has been rigorously applied for the series-production model. With their fresh interpretation of the classic two-box design, the Mercedes designers have created an emotive exterior with a pronounced sporty flair. "Applying the new dynamic style of Mercedes-Benz to the compact class was a challenge that we thoroughly enjoyed," explains Gorden Wagener, Head of Design at Mercedes-Benz. "The almost sculptural lines of the A-Class are very typical for Mercedes. The feature lines, particularly along the sides of the car, then give the A-Class structure and tautness."

The objective when it came to the interior design was to complement the sporty look of the exterior. On top of this the car has a high-quality feel about it that is unique in this segment, achieved both through the design idiom as such and through the choice and combinations of the high-quality materials used. As seen in the Concept A-CLASS, there is an option allowing a smartphone to be fully integrated into the operating and display system. A special app makes it possible to use the full functionality of the iPhone, and in due course also of other smartphones, in the car.

Sporty exclusivity: the A-Class Sport offers a fresh definition of dynamism

For the first time, the performance specialists from AMG were involved in the development of the compact class from a very early stage. The result is the most dynamic version of the new model series - the A-Class Sport "engineered by AMG", in which the visual affinity to the Concept A-CLASS is at its most evident - particularly in terms of the new diamond grille. The A-Class Sport features exclusive 18-inch AMG light-alloy wheels in a 5-spoke design with 235/40 R18 tyres all round and painted high-gloss black with a high-sheen finish, together with red-painted brake callipers. These give an indication of the particularly dynamic driving qualities of the A 250 Sport and the A 220 CDI Sport, which are differentiated, amongst other factors, by a special AMG-developed front axle and a suspension that has been configured to match.

Hints of red on the AMG front and rear aprons also serve to emphasise the expressive positioning of the new model. The contrast between black trim and additional accents in red continues in the interior: the contrasting decorative topstitching on the steering wheel and seats is in this same bright shade, as are the seat belts. The ambient lighting of the instruments and the highlight rings of the air vents are similarly red.

Drive system: new petrol and diesel-powered engines

A broad range of both petrol and diesel engines has something to suit every performance requirement, whilst also demonstrating the current state of the art in terms of efficiency: for the first time, a Mercedes-Benz will produce emissions of just 99 g of CO2 per kilometre.

The bandwidth of the new generation of petrol engines with a displacement of 1.6 and 2.0 litres ranges from 115 hp in the A 180 and 156 hp in the A 200 through to 211 hp in the A 250. Common to all is the combination of direct injection and exhaust gas turbocharging, a more advanced combustion process and an extended stratification range for lean-burn operation that uses fast-acting injectors for the multiple injection of the fuel as well as on-demand multi-spark ignition. CAMTRONIC is an innovation that will be celebrating its world premiere in the 1.6-litre engine: adjusting the valve lift on the intake side restricts the amount of fresh mixture used in the partial load range, so reducing consumption.

The diesel engines also offer an impressively high level of efficiency and environmental compatibility, thanks to sophisticated injection technology and turbocharging. The A 180 CDI offers an output of 109 hp and a maximum torque of up to 250 Nm, while the A 200 CDI has a maximum output of 136 hp and torque that rises to 300 Nm. The A 220 CDI has a displacement of 2.2 litres, an output of 170 hp and torque of  350 Nm, delivering absolutely exceptional performance in the A-Class.

All engines in the new A-Class feature the ECOstart/stop function as standard. The engines can be combined either with the new six-speed manual transmission or, as an option, with the 7G-DCT dual-clutch automatic transmission.
