A longer and better lifted rear reduces the uplift to the rear axle. Furthermore, the cross-section of the vehicle is rounded off more, which reduces the crosswind sensitivity. Finally, a round cockpit glazing is created, which resembles a droplet in the layout and cross-section. Previously, racing driver Rudolf Caracciola, European champion in 1935 and 1937, had rejected such a window due to the risk of distorted vision. Now, together with a supplier, Mercedes-Benz finds a solution that is both visually and aerodynamically satisfying. The systematic streamlining of the vehicle is also underlined by the covered wheel cutouts.
