摘要

The system has a body comprising housing units that create swirling zones. An air suction slot (20) is formed in a longitudinal axis of a motor vehicle (1) in the upstream of the swirling zones. A slot (21) for blowing the sucked air is formed in the longitudinal axis of the vehicle in the downstream of the swirling zones. The blowing slot controls the air flow at the level of rear part of the vehicle. An independent claim is also included for a motor vehicle including an aerodynamic system.
