Cadillac Seville Models & History 1991

The Seville sedan and Seville Touring Sedan (STS) again comprised the Series 6K lineup.

Updates and revisions mirrored those charges listed for the Eldorado, with the exception of the following: The STS received new blue-tinted outside rearview mirrors as standard equipment and its seating area was revised.

In addition to redesigned seats, new full Beechwood leather front bucket seats included six-way power seat adjusters, power recliners and power lumbar support for driver and passen�ger. There was also a full-width rear leather seat with integral headrests. The previously seen rear console was eliminated to accommodate a third center rear seat passenger.

Final drive ratio for the Seville sedan was 2.97:1 while the SLS’s was 3.33:1.

The STS was equipped with the firmer ride and handling of a tour�ing suspension package. It included 23mm front and 16mm rear stabilizer bars, special 16-inch forged aluminum wheels with Goodyear Eagle GT4 P215/60R16 tires. A touring package with 15-inch cast aluminum wheels and Goodyear Eagle GT4 P215/65R15 tires was optional on the Seville sedan.

High-gloss birdseye maple wood was used to accent the Seville’s instrument panel and console, while the STS exclusively featured elm burl high-gloss wood in all door panels, instrument panel and console.

The 1991 Sevilles also received a new taillamp treatment and neutral density back-up lamps.
