Abstract

In a motor vehicle, especially in passenger motor vehicles, its vehicle floor is constructed in the rear area rising toward the vehicle end for achieving a good traction of the vehicle; an air foil with an air foil profile is arranged in the rear diffusor formed thereby at a distance from the road surface that corresponds to the distance of the vehicle body in front of the vehicle rear section of the vehicle so that a negative lift becomes effective at the air foil with an in-flow of air coming from the vehicle front section.
