The 2009 Cadillac CTS-V is a limited-production, very high-performance sedan based on the mid-size CTS sport sedan. The model is the latest in a series of Cadillac V-Series cars, all oriented toward top performance, motorsports, and exclusivity. The new CTS-V returns completely redesigned for 2009, with an appearance that borrows heavily from the standard CTS but adding, most notably, a supercharged, 6.2-liter V-8 engine making 556 horsepower--enough to take on the best sport sedans from Germany.
