One thing I noticed was that as I added aeromods to reduce my car's Cd, the non fan assisted air flow also got progressively less as I reduced the front high pressure/rear low pressure differential that drives air flow through the vents in most cars. So, in an ultra-low Cd car, is it more efficient to run the vent's electric fan (with its attendant alternator load) to provide cabin ventilation or is it better to accept the added drag of a vent scoop on the hood or windshield to move air through the cabin.
