The high-end trim level connected to the DeVille from 2000 to 2005, the DTS nameplate was applied across their full-sized sedan line starting in the 2006 model year. At 207.6 inches in total length, the Cadillac DTS was the longest car-based vehicle offered from the General Motors luxury car division from 2006 to 2011. Catering to executive luxury car duties, comfort as well as performance was both well represented in the four-door, front-wheel drive sedan. DTS boasted impressive V-8 power and a body shape adhering to an aerodynamic 0.32 drag coefficient. Propelled by a 4.6-liter Cadillac Northstar V-8 engine, the 2006 DTS delivered standard power output at 275 horsepower or up to 292 horsepower when opting for the Performance package.
Available between 2006 and 2009, the DTS Performance package also featured standard 18-inch wheels and Magnetic Ride Control suspension. The Cadillac DTS passenger compartment could be configured for five occupants or be ordered with a six-passenger interior through the addition of a front bench seat. Leather seating, dual-zone climate control and an eight-speaker AM/FM stereo system with CD player was standard equipped on the large luxury sedan. The 2008 DTS Performance trim package was replaced by the Platinum model that added a DVD navigation system as well as LED interior ambient lighting.
Advanced accident avoidance features such as Lane Departure Warning and Side Blind Zone Alert were made optional in 2008. Serving as a state car or limousine, a DTS-L model of the Cadillac sedan was offered as a lengthened vehicle starting in the 2007 model year. DTS has also acted as the basis of exterior design for the limousines built for the president of the United States. The DTS was discontinued in 2011 and marked departure for the Northstar V-8 engine and technology family. In 2012, the XTS sedan replaced the Cadillac DTS.
