For 1994, the De Ville was redesigned to share the K-body platform with the Seville. The body was redesigned, although the wheelbase remained 113.8 inches—rather than the 111 inches used on the Seville. Production moved to Hamtramck, Michigan. The name was shortened from Sedan de Ville to DeVille.
The DeVille Concours was available with the new 270 hp (201 kW) LD8 Northstar V8, while lesser models retained the 4.9L L26 V8 until 1996. That year, the base model took on the lower-output Northstar while the Concours moved up to the high-output L37 Northstar, with 300 hp (220 kW). The DeVille Concours replaced the 1987–93 Cadillac Sixty Special.
The DeVille received a minor redesign for the 1997 model year, and added the d'Elegance trim line to replace the Cadillac Fleetwood. New headlights and a new grille were added, the rear wheel skirts were removed, the interior door handles were redesigned, and the black/chrome trim was replaced by a double chrome trim in the base DeVille, chrome and gold trim in the d'Elegance, and chrome and body colored trim in the Concours. The interior gained a new dashboard design that hid the passenger airbag seams and new door panels with front side-airbags and the availability of OnStar system. Production of this generation ended in July 1999.
