Colibra and Porsche Carrrera GT have skirts in the horizontal plane, almost perpendicular to the sides of the car.

I suppose this is to fair the air that flows obliquely out from under the car, easing its exit, but somewhat fencing off side gusts so they don't go under the car. Sort of a crude flow valve, where air flows more easily out than in.

Perhaps it also fairs and smoothens the flow from the wake of the front wheels.

Your thoughts?
