The FED (Fuel Efficient Demonstrator):

The FED employs plenty of carbon fiber and aluminum as a weight-reducing measure, which helps give this four-seater a 30-percent improvement in fuel economy over current military vehicles. Yet even after such a significant increase in efficiency, the FED only gets seven miles per gallon. Under the carbon fiber hood, the FED is powered by a turbocharged and supercharged Cummins four-cylinder engine putting out 200 horsepower and 568 pound-feet of torque. That helps produce enough power to allow the 15,000-pound FED to have a top speed of almost 75 miles per hour. (Source)
