Abstract
An aerodynamic arrangement is arranged in the rear area of the rear end of a passenger motor vehicle which is composed of a guide element provided at the top side of the rear end and of a wing disposed thereabove, whereby the resulting nozzle-shaped gap has an inlet opening which is located in a vertically extending plane. A rear separating edge of the guide element is arranged at approximately one-third to one-half the length of the wing. An aerodynamic arrangement is created at the rear end of a passenger motor vehicle by this construction which with low structural height assures a good visibility toward the rear and by means of which, in addition to a reduction of the air drag coefficient, an effective negative lift at the rear axle is achieved at the same time.
