Although GM has yet to officially confirm the Converj project, the electric-powered coupe has been rumored for production for several months now. The Detroit automaker has spent over $1 billion developing the Volt's revolutionary range-extending system and is keen on spreading that cost over several models. The Cadillac badge would also help to defray more of the costs as it could command a higher retail price than the Chevy branded Volt. GM has already announced an Opel-badged version of the Volt - dubbed the Ampera - for 2011.
It remains to be seen if the Converj will grow two-rear doors for production, but GM marketing head Bob Lutz has indicated that should the Converj make production it would closely mirror its concept counterpart - following in the footsteps of the Chevrolet Camaro. No word on when the Converj will hit Cadillac dealerships, but we don't expect to see the range-extending plug-in hybrid until at least 2012.
