This invention relates to aerodynamic devices for wheel supported land vehicles such as automobiles. The basic invention as illustrated in FIG. 1 shows an aerodynamic device comprising a plurality of winglets (1) projecting from lower/side body surface regions of a wheel supported land vehicle (2). The principal use of this invention is to produce an aerodynamic downforce on said land vehicle. In general winglets installed at negative angles of incidence will produce such a downforce. A downforce may be produced by downforce components on the winglets themselves and also as a result of pressure distributions induced by the winglets on body surface regions of said land vehicle. This aerodynamic device may also be used for drag reduction or control purposes.
