DETROIT (AP) — General Motors says it will reconfigure the factory that makes the Chevrolet Volt so it can produce up to 60,000 electric cars per year.
Currently the plant in Detroit can make about 16,000 of the cars annually.
The company will shut down the plant for four weeks in June for the upgrades.
The Volt can run on battery power for about 35 miles before a gas-powered motor kicks in to generate electricity to run the car. It can be recharged through a home electrical outlet.
GM says the Volt will be in short supply over the next three months. The company says the upgraded plant will be able to meet global demand for the Volt and its European counterpart, the Opel Ampera.
