The Cadillac DTS (DeVille Touring Sedan) replaces the Cadillac DeVille as that carmaker's largest luxury car for the 2006 model year. The DTS follows the naming and styling direction set by the earlier CTS and STS.
The design of the DTS was introduced in a unique way. A specially-designed and outfitted presidential DTS limousine was utilized during the second inauguration of George W. Bush in the January 20, 2005 parade. While details of the vehicle, codenamed Stagecoach, are highly classified, it is presumed to be heavily armored and feature advanced communication equipment. The production DTS was shown at the 2005 Chicago Auto Show on February 9.
