At the time the nameplate was first applied in 1975, Seville represented Cadillacs smaller sedan. By the 1990s, the addition of the Cadillac Catera and later the CTS, the vehicle became mid-level sedan in the luxury brand. For 1998, the front-wheel drive Cadillac Seville entered a new generation with a longer wheelbase than its previous model. Standard features found on the 1998 Seville include dual-zone climate control, self-leveling suspension, traction control, cruise control and 16-inch alloy wheels.
OnStar, CD changer and rain sensing windshield wipers were also available on the 1998 Cadillac Seville. Both the SLS and STS received the Cadillacs 4.6-liter V-8 Northstar engine paired with a four-speed automatic transmission. The Seville SLS was powered by 275 horsepower while the STS model delivered higher output with 300 horsepower. With the Cadillac Seville STS appealing as a more performance-oriented model, the more powerful engine was accompanied in 2000 by styling touches such as a monochromatic exterior appearance. For the 2001 Seville line-up, HID headlights, 17-inch chrome wheels and a hands-free cellular phone system was made available on the high-end variant. In 2003, fast-reacting Magnetic Ride Control was introduced to the Cadillac Seville. The Seville SLS look also incorporated more STS style details during the same model year. Cadillac discontinued the high-end Seville STS after 2003 with production of the SLS concluded one year later. The Seville name was retired after the 2004 model year by Cadillacs redesigned mid-level luxury car called the STS.
