Cars that run on only one type of fuel? That's so pre-millennium. How about a car that runs on wine? Or cheese? Or both? Showcased at the 5th annual Bridgestone sponsored Eco-Rally that goes from Oxford, England to London, the wine and cheese powered vehicle was just one of many automobiles featuring low and zero-emission fuel sources. Not only can the Lotus Exige 270E Tri-Fuel run on a wine-based ethanol (not safe for human consumption) and whey -- a by-product of cheese -- but the car is one of the fastest in the world, going from zero to 60 mph in fewer than four seconds. The Exige can also run on petroleum fuels and methanol (made by condensing CO2 from the air) in addition to its preferred diet of wine and cheese.
