Concept cars, or similar evolutionary vehicles based on them, may never see production.

The General Motors Ultralite was a 1992 low emission vehicle concept car intended to demonstrate the benefits of advanced materials and low fuel consumption. The carbon fiber shell was fabricated by Scaled Composites and it amounted to only 420 pounds. The total weight was 1,400 pounds (635 kg). Its 3 cylinder 1.5 L two stroke engine could produce 111 hp (83 kW), which made a speed of 135 mph (217 km/h) possible. The goal was to make a four passenger show car capable of 100 mpg (2.4 L/100 km). It was rated at 88 mpg (2.7 L/100 km) by the EPA.

The shape was reminiscent of the Ford Probe concept, and the Ultralite presaged the production General Motors EV1 electric vehicle and other production models.

This vehicle was also featured in the 1993 film, Demolition Man as squad cars used by the fictional SAPD (San Angeles Police Department).
