2003-2007 Cadillac CTS: Year-to-Year Changes

2004 Cadillac CTS: A new, larger V6 engine choice and a revised suspension highlighted 2004 changes to Cadillac's entry-level model, which was positioned as a sporty near-luxury sedan. The new engine was a 255-horsepower, 3.6-liter V6, available only with a five-speed automatic transmission. It joined a 220-horsepower, 3.2-liter V6 that was now available only with manual shift. Cadillac said CTS's suspension revisions were designed to smooth the ride. Available with either engine was a Sport Package that included 17-inch wheels, an antiskid system, speed-variable steering assist, upgraded brakes, and a rear load-leveling suspension. Midyear brought a high-performance CTS-V model with a V8 borrowed from the Chevrolet Corvette.

2005 Cadillac CTS: Cadillac introduced a new 2.8-liter V6 for 2005, developing 210 horsepower and slotted below the 3.6-liter. At the other end of the spectrum, heavy-footed fans could choose the CTS-V with its 400-horsepower, 5.7-liter V8 and six-speed manual gearbox. A six-speed manual transmission was standard for either V6, with the five-speed automatic an option. Leather upholstery was optional for the CTS 2.8 and standard on 3.6 and CTS-V models. Xenon headlamps and an antiskid system were standard on the CTS-V and optional for V6 versions. Cadillac's CTS-V featured unique exterior and interior touches, a sport suspension, and 18-inch run-flat tires. Satellite radio and a sunroof could be installed on all models.

2006 Cadillac CTS: Cadillac's smallest sedan gets revised sport and performance packages for 2006. For '06, the available Sport Package adds to V6s a limited-slip differential, antiskid system, xenon headlights, sport suspension, and 17-inch wheels vs. 16s. The revised Wheel Performance Package adds to the 3.6 model speed-variable steering assist, uprated brakes, sport suspension, load-leveling suspension, and 18-inch wheels. Added during the model year, the Wheel Sport Appearance Package gives the 3.6 CTS-V-style trim elements.
