ABSTRACT:
An aerodynamic drag reducing device for a pickup truck includes a tonneau cover which extends between the side walls of the pickup box and forwardly from the tailgate to a distance short of the passenger cab so that the tonneau cover encloses a rearward portion of the pickup box. Tonneau covers enclosing the rearward portion of the pickup box to a range of approximately 40 to 60% of the total length of the pickup box provide a greater reduction of aerodynamic drag coefficient than obtained with a tonneau cover enclosing the full length of the pickup box.
