When an enthusiast thinks of a performance sedan, Cadillac usually doesn’t come to mind. Well, Cadillac is trying to change that. The new 2006 STS-V is stepping into the arena and is well outfitted with a 4.4-liter, supercharged V8 that produces a stunning 469 horsepower and 439 lb.-ft. of torque. All of that power is run through a six-speed automatic transmission to the rear wheels. Notably, the 2006 Cadillac STS-V now holds the honor of possessing the most horsepower of any Cadillac ever created.
