What is the Cadillac DeVille?
The DeVille was a large Cadillac sedan and a central name in the marque’s American luxury-car range. Earlier in the period covered here, it was also offered as a coupe. Its spacious format and front-wheel-drive layout shaped its place in Cadillac’s lineup.
The sixth-generation DeVille marked a major change, moving to front-wheel drive with a transversely mounted V8. Later generations continued with front-wheel drive, and the Northstar V8 became a notable engine in the seventh and eighth generations.
DeVille generations
The sixth generation ran from 1985 to 1993 on the C-body platform. The seventh followed from 1994 to 1999 on the K-body platform, bringing a new design and Northstar V8 availability. The eighth generation ran from 2000 to 2005 on the G-body platform, continuing the front-wheel-drive sedan format.
Across these generations, the DeVille evolved from its front-wheel-drive redesign into a large sedan with updated styling and technology.
