GM's Volt-based Cadillac ELR Coupe is headed for production in late-2013

All the way back in 2009, General Motors unveiled the sleek, 2-door Cadillac Converj concept at the North American International Auto Show. Converj was set to be based on the same plug-in technology powering GM's extended-range electric Chevy Volt, but wrapped in a more luxurious package.

At the time we felt an upmarket application of the Voltec powertrain might be just the way for GM to increase its margins on the expensive hybrid-electric technology. (The Volt's $40,000 price tag seemed much more appropriate for Cadillac than Chevy.)

Then, in March of 2010, it was reported that GM had suspended its Converj program, leaving us to wonder if we'd ever get to drive an electric Cadillac. However, in August of 2011, GM confirmed that Converj was back--this time called the ELR coupe--but, details remained scarce.

Last month, spy photos of a camouflaged Cadillac ELR began to circulate online, leading some to speculate as to a possible production date.

Well, now it's official. GM confirmed Tuesday that production of the ELR will begin in late-2013, assembled at the automaker's Detroit-Hamtramck plant.

It's been a long wait, but--given the slow pace of alternative vehicle growth--we're just as excited for the ELR now as we were back in 2009.
