Volkswagen 1 Liter Car

282 miles to the gallon! It is really small but if you try you can succeed. Here is Tree Hugger on the 1 liter car.

The 1-Liter car has been around in prototype form since 2002 and greens everywhere have been drooling at its 282 miles per gallon fuel economy (or 1 liter of gasoline per 100 kilometers, hence the name). VW has finally decided to make more and sell them, and a limited edition (estimated in the thousands) should start selling in 2010.

1-Liter Car Technical Specs
The One-Liter car (or 1-Litre, over in Europe) weights only 660 pounds. The body is made from carbon composites and it is shaped to be extremely slippery, giving it a coefficient of drag of only 0.16 ("the average car comes in around 0.30 and the Honda Insight had a Cd of 0.25"). The prototype was powered by a 1-cylinder diesel engine, but the production model should have a 2-cylinder diesel (which means it could be powered by algae-biodiesel!), and maybe even a stop-start anti-idling feature (to cut the engine when the car is stopped).
