Powering the concept is a turbo'd two-liter in-line four running off of bio-diesel, which produces 280 hp and 369 lb.-ft. of torque. The chassis is still pure Americana, but the stock steel body panels have been nixed in favor of a plastic composite made of plant fibers to reduce weight and lend credence to the GT's environmental cred. Hmm... a turbocharged, four-cylinder diesel Mustang. We're perfectly OK with that.
