Cars that run on gasified organic materials make for fun engineering challenges and slow, burpy cars. But there's still much to respect in this British team's conversion of an old Rover into a land-speed record holder that runs on coffee, the original high-test fuel.
Built by the Teesdale Conservation Volunteers of Durham, England, the Rover managed to hit 66.5 mph, good enough for a Guinness Book of World Records entry. Just don't tell a Finnish politician with a wood-burning El Camino.
