General Motors is widening electric vehicle development beyond the Chevy Volt even though it is making cuts in other areas.

GM has delayed the unveiling of two models including a new Buick LaCrosse initially planned for the Los Angeles motor show this month and also plans to develop a replacement full-size SUV platform.

But sources have told Reuters GM is pushing forward with work to develop a range of rechargeable, or plug-in vehicles that will follow the Volt into the market from 2010.

The new EVs would include plug-ins for Cadillac, Opel and a Chevy-branded vehicle with SUV styling, one source said.

A spokesman would not discuss specifics but said GM has signalled it would use Volt technology in a range of vehicles.

“We’ve always said it’s not a niche product,” he said. “The architecture is flexible.”

Sources have also told Reuters Compact Power has won the race to supply the Volt with battery packs.
