* 4.5L V8 (HT4100): This was the standard engine, producing around 160 horsepower. It was known for its reliability but was somewhat underpowered for the DeVille's size.
* 4.9L V8 (HT4500): This engine was optional and offered more power than the 4.5L, producing around 200 horsepower. It was often found in the DeVille's sportier "D'Elegance" trim level.
* 5.0L V8 (HT4500): This was a later iteration of the 4.9L engine with a few refinements. It was also offered in the D'Elegance trim level.
