Abstract: A drag reduction method and apparatus for reducing aerodynamic pressure drag associated with a vehicle in motion by use of grit, grit tape, or other turbulator to increase the momentum of boundary layer flow over a vehicle. A turbulator, such as grit tape, can be attached to the smooth external body surface of the vehicle to improve upon a vehicles fuel economy.
