A vehicle body has one or more aerodynamic devices mounted on each side of the vehicle afterbody so that a gap exists between each device and the adjacent body side which may be boattailed and/or recessed so as to accomodate the device and to permit a substantial airflow between the device and the vehicle body side and to provide a gap from which that flow is discharged downstream. The device may additionally or instead take the form of spats around the rear wheels of a road vehicle, or as additions to the spats.

[ I claim:] [1.] An aerodynamic stability device for a vehicle having side surfaces and a base surface, motion of the vehicle generating side surface airflow associated with the side surfaces of the vehicle, a baseflow associated with the base surface and regions immediately downstream of the base surface and a wakeflow at the rear and extending downstream of the vehicle, said stability device comprising one or more aerodynamic surfaces, the one or more aerodynamic surfaces, having an airfoil wing section profile with an inner face facing toward the adjacent side surface and an outer face facing outwardly from the adjacent side surface and mounted in a generally upright position adjacent to and spaced from one of the side surfaces of the vehicle on a rearmost portion of the vehicle to provide a gap between the aerodynamic surface and the adjacent side surface of the vehicles, a portion of the side surface airflow passing over the adjacent vehicle side surface and passing over the inner and outer faces of the aerodynamic stability device sufficient to generate a force normal to the direction of motion of the vehicle, the portion of the side surface airflow passing over the inner face of the device passing through the said gap to exit adjacent to, or to form part of either or both of the vehicle baseflow or the vehicle wakeflow.
