Developed jointly by General Motors Design Center and Research Laboratories, the Ultralite concept was created to be the ultimate test-platform for fuel economy. The four-passenger vehicle features a carbon fibre monocoque structure that combines high-strength with exceptional weight savings. Due to efficient packaging techniques and use of lightweight materials throughout, Ultralite’s curb weight is a mere 1,400 pounds. The concept also incorporates low rolling resistance tires and a 1.5-litre, three cylinder, two-stroke engine that delivers 111 bhp at 4500 rpm. Fuel economy is EPA rated at 80 mpg (highway).
