Federal safety officials have launched a probe into whether the batteries in Chevrolet's Volt plug-in hybrid sedan are prone to fires.
The probe by the National Highway Traffic Safety Administration was launched after a Volt caught fire following a crash test, General Motors Co. said. The agency will be looking at the safety of batteries from several makes of electric vehicles, according to the Associated Press.
The Volt is designed to run off its batteries for about 40 miles. When the batteries run low, a gasoline engine kicks in and functions as a generator, powering the electric motors and extending the range of the sedan to more than 300 miles.
Other electric cars currently for sale include the Nissan Leaf and Tesla Roadster. Several other automakers, including Ford, Mitsubishi and Toyota plan to launch sales of electric vehicles and plug-in hybrids in the coming months.
