The Cadillac CTS-V coupe has been back on ever since GM vice chair Bob Lutz said it was back in July.

Today we learned the production 2011 CTS-V coupe will be in Cadillac's booth at the 2010 Detroit Auto Show, so we'll expect full details and photos to be released in early January. And we'll expect the car to follow the CTS-V sedan in every detail, 556-horsepower supercharged V8 and all.
