ABSTRACT:
An apparatus is disclosed for increasing the fuel economy of motor vehicles having a cargo carrying bed with a movable tailgate panel. The apparatus adjustably positions the tailgate panel between the upstanding closed position and the horizontal loading position automatically in response to the force of wind or air pressure acting on the tailgate panel to reduce the air drag resistance on the motor vehicle. The apparatus includes a suitable biasing means, such as a mechanical spring or a conventional door closure, to adjustably position the tailgate.
