Abstract: Vehicles, and particularly vehicles configured for high speeds and competitive racing, generally employ aerodynamic elements to provide downforce at increased speeds to improve vehicle safety and performance. The present disclosure relates to a method, apparatus, and system of providing aerodynamic lift forces and downforces on a vehicle, including generating lift forces and downforces in response to air flowing over a bi-directional splitter from a fore end to an aft end, where the bi-directional splitter includes a first surface, a second surface, and a third surface; generating, from the first surface of the bi-directional splitter, a lift force in response to the air flowing over the first surface; and generating, from a second surface and a third surface, downforce in response to the air flowing over the second and third surfaces, where the first surface is disposed between the second surface and third surface.
