Claim:
A quarter fender assembly comprising: a quarter fender panel for coupling with a support extending laterally outward from a frame rail of a vehicle, the quarter fender panel comprising an upper edge, a lower edge, a leading edge, a trailing edge and a substantially continuous aerodynamic outer surface extending from the leading edge of the quarter fender panel to the trailing edge of the quarter fender panel and comprising: a rear portion having a rear portion rear edge defining the trailing edge of the quarter fender panel; and a forward portion having a forward portion front edge defining the leading edge of the quarter fender panel, the leading edge of the quarter fender panel positioned inboard from the trailing edge of the quarter fender panel; wherein the forward portion comprises a forward portion aerodynamic outer surface to direct air flow in a first direction generally outward from the leading edge of the quarter fender panel to the rear portion, the rear portion comprises a rear portion aerodynamic outer surface to direct the deflected air flow from the forward portion in a second direction to the trailing edge of the quarter fender panel, and the substantially continuous aerodynamic outer surface comprises the forward portion aerodynamic outer surface and the rear portion aerodynamic outer surface; and a deflector flap extending from a top edge of the quarter fender panel a selected distance to contact a trailer, the deflector flap comprising a deflector flap upper edge, a deflector flap lower edge, a deflector flap leading edge, a deflector flap trailing edge and a substantially continuous aerodynamic deflector flap outer surface extending from the deflector flap leading edge to the deflector flap trailing edge and comprising: a compressible region; an outboard section having a deflector flap rear edge defining the deflector flap trailing edge; and an inboard section having a deflector flap front edge defining the deflector flap leading edge selected for contact with an airflow, the deflector flap leading edge positioned inboard from the deflector flap trailing edge; wherein the inboard section comprises an inboard section aerodynamic deflector flap outer surface to direct air flow in a direction generally outward from the deflector flap leading edge to the outboard section, the outboard section comprises an outboard section aerodynamic deflector flap outer surface to direct air flow deflected from the deflector flap inboard section in a direction to the deflector flap trailing edge, and the substantially continuous aerodynamic outer surface comprises the inboard section aerodynamic deflector flap outer surface and the outboard section aerodynamic deflector flap outer surface.
