So this picture is inaccurate:



Both 2D representations are incomplete. Without the inward rolling vortexii coming off the B-pillar to feed the engine air.

Note also 1500CFM of heated air ejected as a jet under the rear bumper.

Completely!
The 1500cfm would be a contingent upon the bi-metallic, thermostatically-controlled cooling fan inlet bell-mouth position.
