  • Dynamic automobile wing
    Patent number: 7770962
    Abstract: Apparatus and method for an airfoil being disposed on the rear of an automobile or like vehicle. The angle of the airfoil is controlled by a bob weight connected to the airfoil through a series of linkages so that when the vehicle accelerates or de-accelerates, the angle of the airfoil is adjusted. The linkage between the airfoil and the bob weight controls the angle of attack of the airfoil so as to optimize vehicle down force on the tires so as to optimize performance.
