Just a few days ago, our sister site GreenCarReports brought you the exclusive news that the Cadillac Converj was once again headed to production. Today, Cadillac confirmed the news, revealing the ELR.

The ELR is billed as the production version of the Converj, though it is still early in its development cycle. Performance, pricing, and market release are therefore all still either secret or undetermined. We expect more photos or design sketches to emerge soon.

The ELR will get its power from an electric propulsion system that uses a T-shaped lithium ion battery pack, an "electric drive unit," and a four-cylinder onboard engine-generator--much like the Chevy Volt, and as GreenCarReports indicated, likely an evolved verion of the Voltec powertrain.

Don Butler, Cadillac's marketing VP, said, "The concept generated instant enthusiasm. Like other milestone Cadillac models of the past, the ELR will offer something not otherwise present--the combination of electric propulsion with striking design and the fun of luxury coupe driving."

Cadillac also announced plans to unveil a completely different, all-new concept car tomorrow at Pebble Beach. We'll bring you the details on that car as soon as possible. In the mean time, you can read our preview of the Converj concept here.
