During the 1976 Frankfurt International Auto Show the Cadillac Seville introduced its advanced engineering and sophisticated design to the public to move Cadillac forward. The Cadillac Seville began production on the GM rear-wheel-drive K-body platform from 1976 to 1985 and then moved to the front-wheel-drive C-body platform starting in 1986 for better efficiency and expanded interior space. A 5.7 liter Oldsmobile V8 engine with 350 cubic inches enabled the original Cadillac Seville model to deliver outstanding performance. Throughout its development stages the Seville introduced various engines which boosted power output while enhancing fuel efficiency. The first Cadillac Seville model operated with a three-speed Turbo-Hydramatic 400 automatic transmission while subsequent models received an upgraded four-speed automatic to enhance efficiency and acceleration smoothness. The Cadillac Seville produced outstanding interior space with its 114.3-inch wheelbase and 204.0-inch length that allowed it to keep a streamlined profile. The model offered two distinct version configurations between the SLS and STS Sedans to meet the demands of several customer groups. Seville vehicles benefited from continuous updates to authentic parts which Cadillac provided to ensure dependable performance quality. The Cadillac Seville stands as a standard for luxury sedans because of its sophisticated engineering and superior materials which result in a polished driving experience.
