BMW's H2R: 185mph powered by hydrogen
We dig the zero toxic emissions, but come on, that you can let BMW's H2R open up to 60 in about 6 seconds and top it out at 185 mph while the exhaust squirts steam out the back is pretty rad. The body styling something to be desired, but they more than made up for it by, you know, having a non-polluting engine. Besides, it's not like you're ever going to ride (or see) it anyway, so who cares?
