Kinda Mazda derivative in looks, but these guys are serious. F1 is tossing this idea around as well. The next ten years should be interesting. Alot depends on gasoline becoming very pricey. You wanna affect change? Get a 500bhp Cayenne and flat-foot it everywhere except when pulling the 40' boat with the Hummer Wanna save the earth? Easy! Plant trees! That's my game plan, and I'm sticking to it.
