The de Ville was originally a trim level and later a model of General Motors' Cadillac marque. The first car to bear the name was the 1949 Coupe de Ville, a prestige trim level of the Series 62 luxury coupe. The last model to be formally known as a de Ville was the 2005 Cadillac Deville, a full-size sedan, the largest car in the Cadillac model range at the time. The next year, the Deville was officially renamed DTS (an abbreviation standing for Deville Touring Sedan, itself a trim level on earlier models).
