Underbody
The almost fully closed vehicle underbody plays an important role in the
aerodynamics. The acoustics
in the vehicle are also significantly improved as a result. In the front
section, the air flow is directed
past the front wheels by the displacers (7). In this way, the airflow on the
front wheel is reduced. In the
rear area, the 2 wind deflectors (3) on the axle and the cover of the rear axle
differential (5) contribute
to optimized underbody flow together with the rear diffuser (4), which is
adapted for each drivetrain
design.
