After unveiling the production version of the CTS Coupe at the LA Auto Show just a few weeks back, Cadillac is set to unveil the high-powered version of the very same car at the Detroit Auto Show in January. Plus, it will be joined by an all-new concept car.

As for the V, it will get the Coupe's basic lines plus some more aggressive aero work. Under the hood will be a familiar supercharged 6.2-liter V8 that pumps out an incredible 556-hp and 551 ft-lbs of torque. Also expect some big wheels and tires, massive Brembo brakes and magnetic ride shock absorbers.

The debut of this car was pretty much a given and so we're more excited to see the new concept vehicle. Cadillac says it will be the, "latest in its series of dynamic designs." Past designs have included such impressive machines as the CTS Coupe Concept, Converj and let's not forget the Cadillac Sixteen. Could this new concept be an idea of what Caddy has in store for the ATS 3-Series fighter or the XTS flagship, or is it, perhaps a look further into the future at some sort of sports car or a serious luxury sedan competitor to cars like the BMW 7 Series and Lexus LS?

AutoGuide will bring you live coverage of the Detroit Auto Show starting January 11th.
