Engines for the new A-Class

Significant in output and torque with fuel consumption and comfort.

output, more torque and driving pleasure – these the development objectives for the engines in the new A-Class, which will its world premiere at the end of June and appear in the showrooms of company-owned outlets and Mercedes-Benz dealerships in the The range of engines available for innovative compact car will seven four-cylinder units, three newly developed CDI diesels and a new, turbocharged 142 hp petrol engine. Mercedes-Benz is presenting its first continuously automatic transmission, which can be with any of the engines as an option. A new manual transmission is also its premiere.

Compared to the preceding the output of the petrol and diesel for the new A-Class has increased by up to 38 percent, torque has improved by up to 46 percent. All the engines meet the stringent EU4 emission limits, and a particulate is available on request for the diesel Despite this higher the fuel consumption of the petrol has been significantly reduced.

The for the new A-Class are of a unique design allows installation at an angle of up to 59 behind the front axle. makes the four-cylinder units components in the intelligent safety during a severe frontal they slide downwards to the without damaging the passenger

The output range of the three developed CDI diesel engines from 60 kW/82 hp to 103 kW/140 hp. differences compared with the model include an increase in from 1689 to 1991 cc, ignition pressures and second-generation fuel injection, which with dual pilot and a higher injection pressure bar). These and other lead to a significant increase in and torque, a reduction in exhaust and a noticeable improvement in noise The new A 160 CDI has a roughly nine percent output (60 kW/82 hp) and develops a percent higher torque Newton metres) than the model of the same name. The new 80 hp diesel engine in the A 180 CDI has 14 percent output than the power of the A 170 CDI and makes almost 39 percent torque available between and 2600 rpm.

The flagship model in the new A-Class is the A 200 CDI, achieves new standards in terms of and driving pleasure. The direct-injection with a VNT turbocharger and an ignition of 180 bar has an output of 103 kW/140 hp and develops a of 300 Newton metres over a engine speed range 1600 and 3000 rpm. guarantees rapid acceleration and inter-mediate sprints. The fuel of the CDI models in the new A-Class is at the same level as the previous series.

The optionally available particulate reduces particulate emissions by a 99 percent. It regenerates without and remains effective over a mileage.

Petrol engines: new A 200 with 142 kW/193 hp

Compared to the model, the four-cylinder petrol for the new A-Class show an increase of up to 38 in output and up to 36 percent in torque. At the time the fuel consumption, emissions and noise levels been significantly reduced. the A 200 TURBO the A-Class enters new in terms of performance: with 142 hp this engine achieves a power-to-swept-volume ratio of approx. 70 per litre, making it one of the most units in its displacement class. The torque of 280 Newton metres constant throughout a wide speed range between and 4850 rpm. The turbocharger is a development by Mercedes engineers and colleagues at DaimlerChrysler Research.

In case the increased output and torque of the new A 150, A 170 and A 200 models are on a 100 cc increase in displacement and the use of a variable manifold, which helps to pulling power at lower speeds.

By reducing friction losses in the connecting rod and valve control as well as improving the mixture within the combustion chambers, the fuel consumption of the spark-ignition has been even further Despite their higher the petrol models in the new A-Class consume approx. ten percent fuel that their as measured in the NEDC.

AUTOTRONIC: of the first continuously variable transmission by Mercedes

Mercedes-Benz is a new era in transmission technology with the automatic transmission. This on the principle of a continuously variable in which the ratios are changed by of a variator pulley and a steel belt. As a result the A-Class with no interruption of tractive and the engine reaches its maximum more quickly than a conventional automatic transmission. The variable AUTOTRONIC transmission ensures a high level of and noise comfort.

AUTOTRONIC the driver to choose between two programs. In the Comfort program the keeps the engine speed at the possible level, so that the accelerates more gently and less fuel. In the Sport AUTOTRONIC automatically recognises the driving style and adapts the strategy accordingly. A manual is also available in which the transmission divides the ratio into seven virtual The driver shifts the gears up or by briefly nudging the shift The complete AUTOTRONIC unit has a of only 330 millimetres, making it the most compact continuously transmission.

Like AUTOTRONIC, the standard manual transmission of the A 180 CDI, A 200 CDI and A 200 is a new development. This unit is of aluminium construction and is particularly in operation. The tried-and-tested five-speed transmission is standard equipment for the engine variants of the new A-Class. engineers have made improvements and configured this to suit the new engines.

Engines: presence

Diesel engines: new power units with up to 140 hp of

Petrol engines: increase in to 142 kW/193 hp

Stuttgart, May 25, 2004

The by Mercedes-Benz is a very special in every respect — intelligent and unique. In short: A-Class.

A glance beneath the confirms this: the four-cylinder of this compact car are of a unique which is specially configured for the and offers numerous advantages in an of this size. The most of these is occupant protection: the unit is installed transversely the front axle and inclined at an angle of 59 degrees (diesel 56 degrees). This installed precisely matches the shape of the bodyshell floor panel. a severe frontal collision, the and transmission are able to slide and to the rear against this without damaging the passenger This means that the end of the A-Class possesses the entire potential provided by a system of structural members, absorbing the energy and reducing the loads on the vehicle occupants.

The second major advantage of the engines is their compact Their transverse position, in front of and partly beneath the compartment, is not only extremely but also saves space. It a shorter front end design, a much larger area of the available for the comfort of the occupants conventional designs.

And finally, in to their unique, angled and compact dimensions, the four-cylinder of the A-Class also have a deal to offer in engineering This applies more ever before to the power which Mercedes-Benz will use for the generation of this successful car from autumn 2004.

output, more torque, driving pleasure – these the development objectives for the new and improved and these are achieved together equally impressive progress in of environmental compatibility and comfort, as as a further reduction in fuel

Compared to the preceding model, the in output generated by the petrol and engines for the new A-Class is up to 38 percent. The range extends from 60 hp for the new A 160 CDI to 142 kW/193 hp for the future flagship the A 200 TURBO.

Compared to the previous maximum torque has increased by up to 46 The new A 200 CDI already develops its high of 300 Newton metres from rpm.

Versatility is another advantage of the engine range for the A-Class: instead of six there is now a of seven four-cylinder power which are combined with a five or six-speed manual depending on the torque level. The developed AUTOTRONIC continuously transmission is also available for all variants on request.

The range of and transmissions for the A-Class at a glance:
