R56 Introduction: Bodyshell: Aerodynamics

By using continuous underbody paneling, improved air-dam lips and many improvements to detail, a drag coefficient CX of 0.33 has been achieved on the R56.

In particular, the underbody paneling (new compared to the R50) reduces power losses and plays a large part in achieving the CX objective, but also improves markedly the rear lift value, which with 0.06 can even match sports cars.

A new gutter strip on the A-pillar and aerodynamically-improved door mirrors with integrated spoiler lips keep the side windows cleaner, even in adverse weather conditions.

The whole radiator area has been sealed so that the available cooling air is ideally channeled through the air-conditioning condenser and radiator. Optimum functional efficiency (CX/cooling output) is achieved, depending on the engine, by partial cladding on the upper radiator grille.

The good CX value creates the prerequisite for very good performance, in particular Vmax and 0-100 km/h. At the same time, the improved aerodynamics provide the customer with an advantage in terms of consumption, improving it by approximately 2%.

The lift coefficients of the R56, which are in the sports car range, (CZ1 = 0.03; CZ2 = 0.06) are the basis for the outstanding dynamism of the R56 and improve driving stability even at maximum road speed.
