The 2009 Cadillac DTS is a luxury sedan noted for its comfortable ride and spacious interior. Part of the third and final generation that ran from 2006 to 2011, it's powered by a 4.6L Northstar V8 engine generating either 275 or 292 hp based on the trim. Paired with an automatic four-speed transmission and a front-wheel drivetrain, it offers a smooth drive. The DTS comes with four trims: the Base, Luxury, Premium, and high-performance DTS Platinum. A host of safety features come standard, including antilock brakes, stability control, front-seat side airbags, and full-length side curtain airbags. Its tech highlights include OnStar, satellite radio, and an eight-speaker sound system with a CD/MP3 player.
