In the late 1960s, GM directed its GM division and Pontiac to develop concept mini-cars for urban drivers. Pontiac developed the Pontiac X-4 with a radical two stroke aircraft type radial engine,^[1] and GM developed the XP-883 an experimental plug-in hybrid car demonstrated by General Motors in 1969. Primarily intended as a commuter vehicle, the very small car had a fiberglass body with a design resembling the then-future Chevrolet Vega or Ford Pinto. The two-door hatchback had seating for two adults and two children, though the children sat in rear-facing seats and would enter and exit through the tailgate. It was powered by the combination of a two-cylinder engine and a DC electric motor. Electricity was stored in six 12-volt batteries placed between the rear wheels.

At 35 cubic inches (570 cm³), the engine was small enough to bypass laws of the day mandating emissions control devices. The batteries could be charged using a standard 115-volt wall outlet and could power the vehicle in all-electric mode during city driving. In hybrid mode, it had a maximum speed of 60 miles per hour (97 km/h), which could be reached in 28 seconds. A speed of 40 miles per hour (64 km/h) could be attained in twelve seconds. The electric motor powered the car until it reached 10 miles per hour (16 km/h), at which point the gasoline engine would kick in when running in hybrid mode. At cruising speeds, the gasoline engine would normally provide all of the power.

While the XP-883 was built using off-the-shelf technology, General Motors did not provide an electric car to consumers until about 25 years later, when the GM EV1 was made available for lease (at the same time the factory Chevrolet S-10 EV was manufactured for sale as opposed to strictly for lease^{[clarification needed]}). GM's full hybrid system appeared first in their city buses and their first "mild"^{[clarification needed]} hybrid light vehicles appeared in the first decade of the 21st century. A non-bus light vehicle version of GM's full hybrid system was expected to appear in 2007 (MY 2008^{[clarification needed]}) as the Chevrolet Tahoe Hybrid. As of 2010, GM is preparing to introduce the Chevrolet Volt, an EREV(Extended Range Electric Vehicle) in November.
