The Cadillac Converj Concept, a luxury coupe with extended-range electric vehicle technology, is moving forward as a production car that will be called the Cadillac ELR.

Development of the ELR is just underway, so details on performance, price and timing will be announced later, according to General Motors.

The Cadillac ELR 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. It uses electricity as its primary source to drive the car without using gasoline or producing tailpipe emissions. When the battery's energy is low, the ELR seamlessly switches to extended-range mode to enable driving for hundreds of additional kilometers.

The concept generated instant enthusiasm, the vice president of Cadillac Marketing, Don Butler, said. 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 selected the name ELR to indicate the car's electric propulsion technology, in keeping with the brand's 3-letter international model naming convention.

The Converj Concept sparked the idea of combining the desirability of a grand touring coupe with electrification, the GM vice president for Global Design, Ed Welburn, said. There's no mistaking it for anything but a Cadillac, an aggressive, forward-leaning profile and proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2, Welburn said.

Another new concept, the Cadillac Ciel, was revealed on Thursday, Aug. 18, at a special event prior to the annual Pebble Beach Concours d'Elegance. Cadillac also recently announced it will add two new vehicles to its product lineup in 2012, the XTS large luxury sedan and an all-new luxury compact sedan codenamed ATS.
