Apparatus for reducing the drag of vehicles in motion

Abstract

Apparatus attached to the rear of a large box like vehicle for reducing rear drag, resulting from the movement of the vehicle includes an aerodynamically shaped structure rotatably mounted along at least one of the rear edges of said vehicle. The structure defines an enclosed space facing the rear of the vehicle which extends beyond the rear edges of the vehicle thereby increasing the length of the body of the vehicle and at the same time increasing the storage capacity of the vehicle. In one embodiment the structure includes two doors rotatably mounted along the vertical edges of the rear of the vehicle. The two doors, when closed, form an aerodynamic drag reducer. When access to the rear cargo doors is required the drag reducing doors are unlocked and/or unlatched and swung open to the sides of the vehicle.
