Basjoos...I'm going to look at those solar vehicles some more and see just how they are setup but most of the ones I've seen really look like an airfoil for all the shapes, body, cockpit, wheel pilons...maybe I can get some more ideas tomorrow.
any thoughts on the angle of the front air dam? does it matter if it is flat or angled to toss the air over the hood...angled under I could see it wedging more air under the car.
like this guy but not as exagerated...
