The device includes fan devices associated with each wheel of the vehicle for creating respective auxiliary flows. Conveying devices, associated with the wheel housing, direct the auxiliary flows to a distributor provided with an outlet opening, so that the air flows from the distributors sweep along the bottom of the motor vehicle and exit in the area of the truncated tail portion of the vehicle body in order to create, at least partially, a so-called tailstream produced by a stationary ring vortex.

[ What is claimed is:] [1.] A device for reducing the form drag of a vehicle having an upper surface, side surfaces, a bottom surface and a truncated tail portion, said vehicle having wheel housings and a rotatable wheel mounted in each housing, said device comprising fanning means operatively connected with each wheel of the vehicle for creating auxiliary air flows and conveying means connected to each wheel housing and comprising a distributor provided with an outlet opening in the direction of said truncated tail portion, each conveying means directing an auxiliary air flow from each wheel housing to said outlet opening wherein said outlet openings are substantially laterally offset relative to each other to provide a uniform flow of air along a bottom edge of said truncated tail portion of cooperation with air flows along said upper and side surfaces of the vehicle to facilitate creation of a stationary ring vortex.
