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.
