Phil has said this before and I'll repeat it for the sake of discussion. Attached flow is not the goal! The pressure at the front of a car is great enough to attach flow almost no matter the shape. In fact, if you show me a car without attached flow on the front panel I'll send you a nice drawing of your car.

Anyway. Reducing drag is the goal. Air will most likely prefer a nice, rounded front to a block front. And keep in mind that when you compare it to the EV1, you compare it to a stock car without the giant air dam or gap taping.

That's not to say a car with a flat front can't yield good numbers- the Camaro disproves that- but a smooth transition is preferable.

Carry on!
