Also, I think the aerofoil shape is misapplied to cars. The reason a wing has a front end that's rounded is because it has to work through a wide angle-of-attack range. A plane creates lift by tilting the wing. A sharp front edge on a wing would create vortices when the wing is angled relative to airflow. A car doesn't have to worry about this, only an average airflow vector within some yaw angle hitting it from the front (30 degrees?)
I die a little every time I see a teardrop template overlaid on a car. For the above reason, plus the fact that folks always align the bottom of the teardrop with the ground, as if a vehicle with more ground clearance somehow needs shallower curves up top.
