The good aerodynamic properties make a key contribution to low fuel consumption under everyday conditions. The A-Class Saloon was optimised down to the smallest detail by a multiplicity of computation loops, CAE simulations (computer-aided engineering) and measurements in the wind tunnel in Sindelfingen. In addition to the outstanding exterior shape, there are many small measures that led to the new record: a sophisticated reduction of the frontal area despite significantly improved interior comfort dimensions, an extensive sealing concept (such as the sealing of the headlamp surroundings) as well as almost complete panelling of the underbody, which includes the engine bay, main floorpan, parts of the rear axle and the diffuser.
