The base trim is equipped with dual-zone automatic climate control, leather seats, OnStar, bi-xenon headlamps, a power front seat, remote vehicle start, and a CD/MP3 audio system with satellite radio. Upper DTS trims add heat to the front and rear seats, the steering wheel, the windshield washer, and the exterior mirrors. Also, on the upper trims the front seats are cooled and the driver's seat features memory settings. Front and rear parking assist, StabiliTrak, and brake assist are also part of the upper trim equipment groups. The DTS's interior is voluminous, with seating for five or six, depending on whether a front bench or bucket seats are specified. In either configuration, passengers are ensconced in plush leather. You'll find generous legroom in any seating position, as well as a commodious 18.8 cubic foot trunk. The suspension is clearly tuned for smooth freeway cruising, but the DTS keeps its composure when the road turns twisty in a way your father's DeVille never could. Cadillac's Northstar 4.6L V8 delivers 275 smooth horsepower to the DTS's front wheels. With excellent crash test ratings, respectable 15 city/23 highway mileage estimates, a long list of features, a strong powertrain, and room for the whole family, the DTS remains a solid choice for the luxury car buyer set.
