Just as Chrysler previewed its next-gen 300 sedan and Jeep Grand Cherokee in its viability plan submitted to the U.S. Treasury today, General Motors, too, in its own plan, revealed the final design of the upcoming Cadillac CTS Coupe.

Apart from this official image, the only other details revealed were that the CTS Coupe would enter production at the start of next year at the company’s Lansing plant in Michigan. The viability plan also revealed that the CTS Coupe would be available with a 3.6L V6 engine and six-speed automatic transmission.

As expected, the production CTS Coupe is almost identical the concept version unveiled at last year’s Detroit Auto Show. The Coupe’s front-end is shared with the CTS Sedan but the rear quarters are all-new and the doors feature the same touch-pad releases as used by the Corvette. The rear of the coupe will be dominated by a centrally mounted exhaust stack, tall vertical lamps and an almost flat rear window.

Other important details revealed in the viability plan include plans for a dual-clutch transmission, a new range of four-cylinder petrol engines, and additional extended range vehicles such as the Opel Ampera and Cadillac Converj by 2012. Further down the track GM also plans to launch a new hydrogen fuel-cell powertrain and a more advanced third-generation hybrid system.
