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).
