Powertrain Options and Availability
DeVilles began the decade with a 4.5-liter, overhead-valve V8 engine that sent 180 horsepower to a 4-speed overdrive automatic transmission. Compression ratio of 9.5:1 demanded premium unleaded fuel, and the V8 produced 245 pound-feet of torque. A new 4.9-liter V8 for 1991 was accompanied by an electronically controlled automatic. Horsepower grew to 200, torque to 275 pound-feet. A single "powertrain control module" computer coordinated operation of the engine, cruise control, and transmission. Cadillac claimed more precise and smoother operation. A new interlock in '91 prevented shifting out of park unless the brake pedal was applied.
