An airfoil or deflector panel for being mounted ahead of the rearmost set of wheels of a vehicle such as a truck or tractor-drawn trailer to direct air flow in a manner which reduces the relatively negative air pressure normally occurring behind a moving vehicle. The surface of the deflector which is presented in the direction of vehicle motion has a bilateral or compound convex curve.

A device for reducing the vacuum ordinarily developed in a region immediately aft of the rear of a longitudinally moving vehicle which has a body and laterally spaced apart rear wheels mounted on axles under and near the rear of the body, said device comprising: a deflector panel having a front surface on which air impinges when the vehicle is in motion, said panel extending laterally across the space between said rear wheels and being supported immediately ahead of said rear wheels at a longitudinally angle that results in a major portion of the impinging air being directed downwardly and rearwardly for flowing between said wheels into said region to thereby reduce the vacuum.
