Some AMC Pacers were converted to plug-in electric vehicles.

Electric Vehicle Associates (EVA) of Cleveland was best known for its Change of Pace model – a built-to-order adaptation of the Pacer that was priced at $12,360 in 1978.
The company converted over 100 units.

First available in the sedan version, power came from eighteen 6-volt lead–acid batteries to a 15 kW (20 hp) series DC motor with a stock three-speed automatic transmission.
The EVA Change of Pace sedan weighed 3,990 lb (1,810 kg) and reached 55 mph (89 km/h) with a 53-mile (85 km) range.
Regenerative braking is used in conjunction with the standard hydraulic brake system which utilizes front-wheel discs and rear drums.
Vehicle tests that focused on the electrical drive system including the batteries, controller, and motor "found that the Pacer performance is approximately equal to the majority of the vehicles tested in the 1977 assessment."

Later, a wagon version had twenty VARTA batteries housed in two-packs (front and rear), with a 26 kW (35 hp) (at 3,000 rpm) motor, and the car was complete in every detail down to a gas heater.
The electric Pacer wagon was one of the more expensive cars at $14,000.
The Lead Industries Association (LIA) sponsored a tour for government and industry officials that featured an EVA Pacer wagon.
Consolidated Edison in New York City purchased 40 modified AMC Pacers from EVA.
The United States Army also included EVA Pacers in its inventory of special-purpose electric vehicles.

A video documentary about the Electric Vehicle Association's electric Pacers is titled "A change of Pace."
A fully restored wagon has had its original silicon-controlled rectifier (SCR) control replaced with a modern controller and the "hydraulically operated hybrid vehicle recharging system" removed because of its lack of efficiency to use compressed air from suspension travel to power a small generator to recharge the batteries.
