The neutral foil idea is nice, but you will want down-force at speed, and having a flat bottom curved top (Jaray - 1930's) does just the opposite.
I'm a big fan of what Luigi Colani did with the 300 mpg Vette, and inverted wing for the salt flats.
Quite a few of the solar cars and design student's cars are going this inverted wing route now.
My own automobile sketches have taken this direction as well, I'll post my sketches when I have the time.
