The zero-emission Electrosport concept cars were made using American Motors Corporation (AMC) Hornet sedans and “Sportabout” station wagons from 1971 until 1974.

[3][4] The company also established the “World's First Electric Car Expressway” between Detroit and Chicago - a distance of about 300 miles (483 km) - that consisted of Interstate 94, but with six 50 kW charging stations that were located at Holiday Inn hotels near the highway.

[3] An EFP designed 20 hp (15 kW; 20 PS) direct current series-wound traction motor (the size of a one-gallon paint can) was bolted through an aluminum adapter plate to the car's standard clutch and 3-speed manual transmission.

The exterior of the Electrosport was differentiated from regular production Hornets by a one-piece solid fiberglass body-colored panel in place of the AMC's silver and black plastic grille.

The Hornet's gas cap covered the three-prong plug mounted in the former fuel tank filler hole to which an extension cord connected to 220-volt AC power.

An Electrosport was used by the Golden Valley Electric Association of Fairbanks, Alaska, as a test to help deal with the increasing ice fog in the city.
