Abstract
A drag reduction system introduces pressurized gases to selected regions of a vehicle, such as a tractor trailer combination 100 for reducing the aerodynamic drag thereon. The system 140 or any combination of components thereof may be installed on new combinations or may be retrofitted on existing combinations. The drag reduction system may be controlled to selectively determine which regions receive pressurized gases and at what flow rates such regions receive the pressurized gas.
