The Jetcar isn't jet-powered, but it is a freaky-looking, high efficiency concept with a mandate to achieve 100km per liter of fuel (around 285mpg). The latest prototype, Jetcar 2.5, sports a light steel frame, a body fashioned from epoxy glass resin and a three-cylinder common-rail diesel engine, chosen after electric-battery and hydrogen powered versions had proven uneconomical. It also employs an aerodynamically efficient design only an engineer could love. More pics ahead.
