The Cadillac DTS (DeVille Touring Sedan or D-Series Touring Sedan) is a full-size luxury car that was produced by Cadillac. The DTS replaced the Cadillac DeVille as Cadillac's largest luxury car for the 2006 model year. This renaming followed new styling conventions set by the earlier CTS and STS. The DTS remained in production until 2011, when it was replaced by the XTS.
The first version of the DTS was initially shown at the 2005 Chicago Auto Show on February 9.
