Cadillac Converj will enter in production image

General Motors is planing to build the Cadillac Converj extended-range electric hybrid concept, which debuted at this year’s North American International Auto Show in Detroit. The vehicle will use the same platform and technology developed for the Chevrolet Volt, which will hit the market at the end of next year.

If the Converj follows the Volt formula, it will be powered exclusively by an electric motor that can go 40 miles on a charge. If the trip lasts longer than 40 miles a gasoline engine will start up to supply power to a generator that will keep the vehicle moving for a total of nearly 300 miles.

GM has given no hints on pricing. Recent reports have indicated that the Volt may cost close to $40,000. A special $7,500 federal tax credit for ultra-efficient vehicles will help defray some of that cost, but it’s still a price tag more comfortable for Cadillac shoppers than the typical Chevrolet customer.
