1981 CADILLAC DEVILLE

Standard engine for DeVille and Fleetwood Brougham was the "modulated displacement" 368 cu. in. (6.0-liter) V8-6-4, with digital fuel injection. Optional: a 252 cu. in. (4.1-liter) V-6, provided by Buick. That V-6 had Computer Command Control and a knock sensor to adjust spark advance, as well as diagnostics. The Olds diesel V-8 was also offered.

Externally, DeVilles and Fleetwoods carried a new forward-peaked grille with heavy wide upper header bar (Cadillac script again at the side) over an undivided tight crosshatch pattern. Quad headlamps sat above quad amber parking/signal lamps, with wraparound clear/amber cornering lights. Standard wheel covers displayed a Cadillac crest on dark red background. New standard Electronic Climate Control offered digital accuracy. Standard equipment also included a six-way power passenger seat, power windows, and low-fuel warning. New pillow-style seating came in rich Heather cloth (four colors); or leather in ribbed seating areas (ten colors). Sedan DeVilles could have automatic lap-shoulder belt for driver and front passenger. Other options: a Heavy-Duty Ride package, wire wheel covers, and Elk Grain vinyl roof.
