Bearing a name that traces back half a century in Cadillac culture, the flagship DeVille sedan contains an array of electronic controls and computer-managed mechanical systems designed to improve vehicle stability and safety, visibility, communications, even passenger comfort. A base DeVille shows fabric seat upholstery on a bench-style front seat split in 40/20/40 sections with fold-down center armrest. The DeVille High Luxury Sedan (DHS) contains the same seat but piles on comfort and convenience items, while DeVille Touring Sedan (DTS) installs front buckets clad in leather with internal heat elements and massaging lumbar action. Powertrains consist of the NorthStar 4.6-liter V8. It delivers 275 hp in DeVille and DHS but 300 hp in DTS.
