You can’t buy it, but it might just be the most amazing car that will make its debut at the 2011 Detroit Auto Show next week.

Several weeks ago Cadillac officially confirmed its return to the SCCA’s World Challenge GT series for the 2011 season with the CTS-V Coupe. At the time, only renderings of the track machine were available, but now Caddy has released a whole selection of photos of what could very likely be next year’s championship contender.

Cadillac will field two cars in the series, with three-time America Le Mans Series GT1 champ driving one car and 2005 World Challenge GT champ Andy Pilgrim piloting the other. Pilgrim’s ’05 championship, it should be pointed out, came behind the wheel of the CTS-V sedan race car.

Cadillac will begin track testing the new machine at Sebring International Raceway in the end of January, ahead of the season’s first race, March 25-27 in St. Petersburg, Fla

Stay tuned for more photos from the Detroit Auto Show on Monday, January 10th. Until then, check out AutoGuide’s 2011 Detroit Auto Show Preview here.
