But, actually, just wanted to highlight what a good job, IMO, VW's designers & engineers have done with the Microbus Concept by providing a reference that this crowd is familiar with. Granted, an especially weak one. Couldn't think of how to convey that in fewer words.
By the way, open wheel race cars have a lousy Cd especially with wings but have lots of power to overcome the drag.
AFAIK, for open wheel racers, it's the tires not wings that are the culprits.
