The supportive measures for the engine s performance is accompanied by the aerodynamic package RS consisting of components, which fulfil the highest standards. The front apron and the front spoiler lip not only offer a sporty appearance but also generate additional downforce, which results in an increased tread pressure and therefore more road adhension. Meanwhile the front sparkles with its elegant Carlsson logo on the bonnet and its characteristic grille inserts made of electro-polished stainless steel. The side of the Mercedes appears more dynamic and powerful thanks to the new set of side skirts for the model with long wheelbase.
