The 2003 CTS almost had it all, but the engine wasn't strong enough to fill the promise of the superb new chassis, and the competition from BMW and Audi demanded more than 220 horsepower. The 2004 CTS responds with two punches, a left jab (255-horsepower V6) and right cross (400-horsepower V8).
2004 also brings some needed softness into the interior, and tweaks the suspension to balance that additional horsepower on the road. The handling of the '03 CTS was widely praised, and now it's even better.
