I've been contemplating the relative merits of having a louver in the hood behind the radiator, and seeing if I can get the air inside the engine bay to flow out the front wheel openings?

The hood louver would probably heat up the air that comes in the vent at the base of the windshield. Holes in the inner fenders would be hard to do and they could weaken the structure somewhat?

My next step is to improve the flow underneath the front, and work my way back; with a smooth bottom out of aluminum, probably. I also would like to remake all the current Coroplast panels with aluminum -- and no tape.

BTW, the zigzag tape at the top of the windshield seems to be helping -- it gets ripped off by the air flow, both on my xA and on my Mom's 2005 Prius. I may try to fill in the groove with silicon caulking...
Sincerely, Neil
