Volkswagen XL1 (261 miles per gallon )

Volkswagen XL1 (261 miles per gallon ) : WOWWW...

Much as we love supercars, there's also a lot to be said for automotive marvels on the efficiency side of things, too. Take this funny little Volkswagen XL1, for example – it's an honest-to-goodness production car that will reportedly hit something in the area of 261 miles per gallon. It's certainly not fast nor powerful, and it won't be cheap when it goes on sale, but the fact that engineers are actually capable of building something like this is incredibly remarkable. And props to Volkswagen for keeping that pod-car design intact, as well.
