  • Vehicle boundary layer air flow control structure
    Patent number: 8668244
    Abstract: A vehicle boundary layer air flow control structure is provided with a vehicle body and a side view mirror. The vehicle body includes an exterior contoured surface with an air flow deflector. The side view mirror is attached to the vehicle body to provide a diagonally rearward direction to be viewed from a driver's seat. The air flow deflector has an inward longitudinal air flow guiding surface provided in a vehicle body region of the exterior contoured surface of the vehicle body along which an air flow heading toward the side view mirror passes. The inward longitudinal air flow guiding surface extends in an air flow direction of the air flow with respect to the side view mirror to divert the air flow inward of the side view mirror with respect to a vehicle widthwise direction.
