There is a new zero-emissions vehicle that runs on compressed air called the Air Car. It's made by a French company called MDI and was invested by the CEO and founder of MDI, Guy Negre. It will be introduced in France and India in late 2008. The company plans to offer different models over time, including 2, 4 and 6 cylinder engines at prices ranging from $4,800 to $12,900. The first model, OneCAT holds up to 5 passengers and can go up to 500 miles on the highway with just one fill-up and up to 68 miles per hour. With a 5 passenger capacity this is truly a family friendly vehicle! To fill the engine, you just plug the car in at home and a built-in compressor refills the tank in 4 hours. I know where my next car is coming from!
