GM Chevrolet Volt due by end-2010

General Motors Corp plans to launch its electric car, the Chevrolet Volt, by the end of 2010 , Reuters reports.

GM's Bob Lutz said employees working on the Volt "are becoming increasingly nervous," as the race to bring a mass-market, rechargeable electric vehicle to the market heats up.

"There is a lot of skepticism within the company about the timeline," Lutz said at the Reuters Autos Summit in Detroit. "People are biting their nails, but those of us in a leadership position have said it has to be done."

Lutz said the Volt plug-in hybrid -- which GM plans to road-test early next year and produce by late 2010 -- is crucial to GM's efforts to snag the environmental technology crown from Japanese rival Toyota Motor Corp.
