The mention of the VW GX3 concept car on the Internet BMW Riders list has spun off all sorts of other mentions of small, fast, minimalist cars. If only you could get an Ariel Atom in the states... The likelihood, though, is incredibly low.

It's an open-wheel, open-bodywork, open... well, almost everything 500 kilo 300bhp speed-monster that does 0-60 in just over 2 seconds, and is apparently well-behaved enough to be a daily driver (if you don't need a roof and don't need to haul much). I doubt it's got the fuel efficiency of the VW, but with that sort of performance, who cares?
