ABSTRACT:
A drag reduction system generally comprises a pair of deflectors that conjunctively compensate for the angular designs typical of currently existing vehicles. In one embodiment, the pair of deflectors includes a first deflector positioned proximate the interface between the vertical grille and the hood, for example, near the upper end of the grille crown at the forward end of the hood and a second deflector positioned on the upper hood surface toward the rearward end of the hood, forwardly of the windshield. The first and second deflectors and function in concert, twice maneuvering an air stream to both avoid direct impact with the vehicle and to displace the stream laterally in such a manner that minimizes the amount of work energy expended in its redirection. In one example, the drag reduction system tailors the air stream around the hood and cab sections of the vehicle.
