The STS was Cadillac's highest-priced sedan, falling in size between the mid-size CTS and full-size DTS. In 2006, the DeVille nameplate was replaced by Cadillac DTS, an abbreviation dating back to 1986, when a "DeVille Touring Sedan" package was first available. The new name brought the DeVille into line with Cadillac's Art and Science-era nomenclature, which saw the Seville renamed the STS and the Catera replacement called the CTS. The last DeVille rolled off the Detroit/Hamtramck Assembly line on June 23, 2005.
