Maybe it's one of those outside the template wonders - lots of them.

I just found a good paper talking about some of Jaray and Klemperer's work. If you take a foil and place next to the ground the drag can increase 50% to 500%. However, if you remove the lower camber making it a flat bottom foil you can greatly reduce that drag. You can also arch the top side of the body more to similar affect!

See page 13, rest of the thesis is pretty good too.

Yes,many university teams have turned to airfoils as models for their racer's body.Of particular interest are the laminar profiles.
The fly in the ointment for us ecomodders is how to apply the technology to an existing passenger car.
The wing car typically requires a recumbent or supine driver position to minimize frontal area,something,perhaps most motorists couldn't live with.
And ingress/egress requires the assistance of team members.
Hard to beat on the track though!
