Cadillac's dramatic luxury coupe with extended-range electric vehicle technology. (08/17/2011)

General Motors says production is set to begin late in 2013 of a luxury version of its Chevrolet Volt hybrid.

The automaker said on Tuesday the Cadillac ELR would be assembled at the Detroit-Hamtramck Assembly plant, where the Chevrolet Volt, Opel Ampera and Holden Volt are produced.

The Cadillac will run on electricity.

It will also carry a four-cylinder petrol engine to generate power when the batteries run out of juice. It's based on the Cadillac Converj, a concept car unveiled in 2009 at the Detroit auto show.

GM North America president Mark Reuss said the car was “further proof of our commitment to electric vehicles and advanced technology”.

The company will invest $35 million (R310 million) at the plant, which hasn't produced a two-door car since the 1999 Cadillac Eldorado. - Sapa-AP
