If you've not increased frontal at all, it may produce a result... I feel, however, that increasing A to decrease Cd is probably going to get you less of a positive result than you might first think.
All it takes is for the improvement in Cd to be greater than the increase in A.

Frontal area is kind of an arbitrary number. With the air spilling off the windshield forcing surrounding air upward, it's basically creating an invisible increase in frontal area.


Look at how Jeep cuts off the image
