i understand, but i think that using an airplane wing shape as an example is not so good. one of the main ways a wing gets lift is through the difference in speed between the air passing above the wing, and the air passing below it. on a beetle, or any car really, i would guess that the air passing below the car is minimal, compared to the air going over the top. that is why i think an airplane wing is a bad example.
although airplane wing shape is still probably better then a brick as far as cars go.
there are some smart cookies on this board. why don't you guys apply you're knowledge to designing a combustion chamber, or a fuel efficient cam for the metro engine? seems to be to be a better use of these talents.
