According to Flow Illustrator it
can work...what comes out of the wheel well follows the interior roof bottom line to the back and is released into the vacuum in the rear of the car. My question is if the inlet/outlet points for air in the interior or roof angle can be improved and how.
With a Rn of 5,000,this flow would be of a laminar boundary layer,not possible when the entire vehicle is submerged in the turbulent boundary layer of Earth.
And there's a risk that air would actually flow forwards,from the back of the car to the front,seeking fast-moving,low-pressure regions up front.
