Abstract
An active rear airfoil arrangement (10) for a trailing area of a vehicle having a turbulence creating area. The arrangement (10) is for connection with a static rear horizontal spoiler (20) associated with the rear portion of a vehicle and includes an active rear horizontal spoiler (30a, 30b, 30c). The active rear horizontal spoiler (30a, 30b, 30c) moves to a deployed position and forms a flow passage (48a, 48b, 48c, 48d) that extends horizontally across the top of a liftgate (12). In another aspect of the invention the active rear airfoil arrangement (10) includes vertical left and right active spoilers (32a,32b; 36a,36b) that move to create a flow passage (74,76,88,90) on the left side and right side of a liftgate (12).
