Aerodynamic drag reducer for vehicles

摘要

An apparatus for converting a substantially flat vehicular surface on the rear of a vehicle so as to create at least one surface which operates to reduce aerodynamic drag, comprising: at least one support adapted to be moveably attached to the rear surface of a vehicle; at least one surface supported by the at least one support; the at least one surface movably position so as to move from deployed position extending from the rear of a vehicle to a retracted position; whereby the apparatus operates to reduce aerodynamic drag in the deployed position and does not interfere with vehicle loading in the retracted position.
