The General Motors 1992 GM Ultralite concept car as used in the 1993 movie Demolition Man with Sylvester Stallone and Sandra Bullock. Also a clip with the GM Lean Machine concept vehicle. Both are studies in high efficiency vehicles. The Ultralite weighed only 635kg total and had a Cd of 0.192 allegedly using only 4HP to cruise at 88km/h (55mph). In the movie they have the foresight to make it battery electric but the real concept car used a 3 cylinder combustion engine. Burt Rutan's Scaled Composites company did the carbon fiber monocoque bodywork strengthened by PVC foam core.
