The Chassis
  • Electromechanical speed-sensitive power steering fitted as standard

  • Innovative new spherical parabolic-spring rear axle ensures flawless dynamics and impressive comfort

  • Automatic adjustment of shock absorber force according to situation in hand

  • Latest generation of ESP® with tyre pressure loss warning as an option

A look at the chassis technology under the skin of the new A-Class provides further evidence that the new model differs fundamentally from its predecessor. Added to the mix are a series of new developments which play a major part in four outstanding characteristics of the new Mercedes compact car: active safety, driving dynamics, ride comfort and driving pleasure.

From the steering to the shock absorbers, the brakes to the rear axle, the Electronic Stability Program to the tyres, Mercedes engineers have taken a thorough look at all the chassis components, developed and incorporated innovative new systems and made telling improvements to already proven technology.

The result of this in-depth development and testing work can be seen and felt after just a few kilometres out on the road. The new A-Class takes the combination of dynamic handling and hallmark Mercedes comfort to a level above that offered by its predecessor, with both features enjoying equal importance.

In addition to these technological innovations, basic features of the outgoing model’s chassis have also been modified, some of them fundamentally. The Mercedes engineers have thus succeeded in laying the perfect foundations for further advances in terms of driving dynamics. Indeed, new dimensions for the car’s wheelbase, front and rear track width, wheels and tyres make a significant contribution to the sporty yet comfortable driving characteristics of the new A-Class.
