Spied: 2009 Cadillac CTS-V

Spy photographer Chris Doane caught the 2009 Cadillac CTS-V in testing late Wednesday. So far, we've seen several shots of "ordinary" 2008 CTS test cars. These are the first images to date of the high-performance V-series variant. The prototype has a huge bubble in the hood, performance wheels, wide tires, unique (larger) exhaust pipes and -- our photographer swears -- an obvious "supercharger sound."

According to spy Brenda Priddy, one of the most dependable sources claims the CTS V Series will be powered by a 4.6-liter non-supercharged V8, while others insist -- as the photos seem to show -- a supercharged V8 is in store for the hot CTS. Some sources even claim this car will share the "Blue Devil" Stingray's supercharged V8 -- which could explain why these two vehicles have been spotted in the same general area.

Horsepower estimates have also been all over the board, but it's safe to assume the CTS-V will have somewhere between 550-600 hp. Production should start in the fall of 2008, according to Priddy, with an annual run of 7500 V Series units is expected.
