The Cadillac Converj luxury coupe, which made such a splash back in 2009 with its extended-range EV technology, is destined for production and will be named the Cadillac ELR.

Not many details of the new ELR are available other than that it will feature an electric propulsion system made up of a T-shaped lithium ion battery, an electric drive unit, and a four-cylinder engine-generator.

The Cadillac ELR is powered by electricity, and when the battery's energy gets low, it moves into extended-range mode by switching on the gas-powered generator which enables hundreds of additional miles.

The ELR can also be plugged into the mains to recharge the battery as it uses the same Voltec powertrain as GM's other extended-range electric vehicle, the Volt.

Whether consumers will wish to pay extra for a prestige brand which uses essentially the same internals as the Volt is another matter, but it's a move in the right direction.
