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.

     Functional principle

    If a moving object is detected, which based on the current speed would be in the area in front of or behind the vehicle in approximately the next two seconds, a visual and acoustic warning is issued. When a Cross Traffic Alert Rear is issued, the LED in the mirror glass is also switched on. The
