There's been a battle brewing within General Motors about expanding the Volt platform to include vehicles other than the Chevrolet Volt and its near twin, the Opel Ampera. It was hoped that the Cadillac Converj -- which was shown at the 2009 Detroit Auto Show -- would help expand sales of the platform and help offset some of the development costs due to its higher price tag.

The Detroit News received confirmation late last year that the Converj would actually be produced. However, a new report from Automotive News suggests that GM has actually shelved plans to produce the sleek two-door coupe.

The news comes from none other than "Maximum" Bob Lutz had been proclaiming to the press that the Converj would see the light of day in 2012. Lutz has been a champion of "pet products" within GM over the past few years. Unfortunately for Lutz, many of the vehicles he has championed have also ended up on the chopping block recently (Pontiac Solstice, Pontiac GTO, Pontiac G8, Saturn Sky, etc.). Lutz is also retiring from GM on May 1, so any possible dreams of seeing a production version of the Converj are leaving with him.

"It has always been a concept," added Nick Twork, a spokesman for Cadillac. "It was never announced officially that we were going to do the Converj. We never issued a press release."

The fetching Converj concept car featured a four-seat interior, 21" front wheels (22" in the rear), an all glass roof which incorporated solar panels to help charge accessories (a similar feature is available on the Prius), and LED headlights.
