1993 -

A 4.9-liter, 200-horsepower V8 fed an electronically controlled 4-speed automatic in the basic '92 Eldorado.
That engine continued into '93, but the Touring Coupe adopted a 32-valve, 4.6-liter Northstar V8, rated 295 horsepower.
A 270-horsepower version of the Northstar went into the Sport Coupe. Because that engine reached peak power at lower rpm and yielded an extra 10 pound-feet of torque, it was considered a better choice for around-town driving.
The Sport Performance package also used a shorter (3.11:1) final-drive ratio.


1994 -

For '94, the original V8 was gone, and Northstars powered all El Dorados. Horsepower ratings for both engines rose by five in 1995, and the Touring Coupe's V8 gained a bit of torque.
