1. An active rear airfoil arrangement for a trailing area of a vehicle having a turbulence creating area comprising:
a static rear horizontal spoiler on a rear liftgate of the vehicle and having a top surface;
at least one active rear horizontal spoiler having a top surface and a bottom surface, wherein the at least one active rear horizontal spoiler is capable of moving between a stowed position and a deployed position relative to the static rear horizontal spoiler;
at least one flow passage formed between the static rear horizontal spoiler and the at least one active rear horizontal spoiler when the at least one active rear horizontal spoiler moves to the deployed position thereby reducing the vehicle drag coefficient by controlling the wake of the vehicle using accelerated jetted air, wherein the at least one flow passage formed between the static rear horizontal spoiler and the at least one active rear horizontal spoiler is adjustable by moving between a stowed position, a plurality of intermediate positions and a deployed position relative to the static rear horizontal spoiler;
at least one left side active spoiler and at least one right side active spoiler moveably positioned on the respective left side of a liftgate and right side of the liftgate, wherein the at least one left side active spoiler and at least one right side active spoiler are capable of moving between a stowed position and a deployed position; and
at least one flow passage formed between the at least one left side active spoiler and the left side of the liftgate, thereby reducing the vehicle drag coefficient by controlling the wake of the vehicle using accelerated jetted air wherein the at least one flow passage formed between the at least one left side active spoiler and the left side of the liftgate is adjustable to one of the stowed position, the deployed position and a plurality of intermediate positions between the stowed position and the deployed position;
at least one flow passage formed between the at least one right side active spoiler and the right side of the liftgate, thereby reducing the vehicle drag coefficient by controlling the wake of the vehicle using accelerated jetted air wherein the at least one flow passage formed between the at least one right side active spoiler and the right side of the liftgate is adjustable to one of the stowed position, the deployed position and a plurality of intermediate positions between the stowed position and the deployed position.
