Systems and methods are disclosed that utilize exhausted gases from an internal combustion engine (e.g., piston engine, rotary engine, turbine engine, etc.) of a vehicle for reducing the aerodynamic drag thereon. In some disclosed examples, the systems and methods utilize a generated gas flow from, for example, electric fans, engine driven or pneumatically/hydraulically driven pumps, etc., for reducing aerodynamic drag. The generated gas flows in several disclosed examples are directed in a generally opposing direction of (i.e., against) prevailing cross winds.

Title
