Abstract

A motor vehicle is provided with a rear-mounted air guide device having a rear spoiler provided on a hood at the rear and a connected rear airfoil. The rear airfoil is used only when needed to produce the necessary downforce so that no damage occurs to the air guide device when passing through an automatic car wash. For that purpose, the rear airfoil is movable by a drive device from a retracted resting position into an extended operating position and vice versa. The rear airfoil in the resting position is largely lowered into a groove-shaped receptacle provided on the top of the rear spoiler.
