Cadillac has just announced that the production version of its 2009 Detroit Auto Show show star, the Converj Concept, is on the way. Dubbed ELR and borrowing technology from the Chevrolet Volt, the on-again, off-again angular coupe had been rumored anew in the last few days. Now, Cadillac has officially confirmed that development of the extended-range electric coupe is already underway.

While no specs are being given, Cadillac is confirming that the ELR will use a version of the same Voltec drivetrain as the Volt, though probably v1.5, and the on-board generator will again be a gasoline four-cylinder engine.

The Wreath and Crest brand isn't giving much insight as to why the letters E-L-R have been chosen, only saying they want to "indicate the car's electric propulsion technology" and remain consistent with the brand's three-letter naming scheme. Maybe they stand for "Electric Luxury Ride," or maybe someone over at General Motors is a big Everybody Loves Raymond fan. What do you think ELR stands for? Have your say in Comments.

I really like the look of this thing, resembles the CTS coupe a lot though.

I love the new caddy G6 errr au um I mean Converj errr au um ELR or whatever you call it. lol

Only thing I would change is the headlights not a fan of that one thing. The interior is sick looking. The side profile is killer along with the back end.

That looks BA! Something to compete with the Luxury hybrids, like the pretty cool looking Lexus ones.
