Cadillac STS

The STS (Seville Touring Sedan) was a full-sized four-door sedan manufactured and sold by Cadillac from 1988–2012. The STS was the successor to the Cadillac Seville.[3] That car used the STS name, standing for Seville Touring Sedan on upscale performance-oriented versions beginning in 1988. In 1992, Cadillac split the Seville line into STS and less performance-oriented SLS (for Seville Luxury Sedan) trim lines. The next year, the STS received Cadillac's then-new Northstar System, including the aluminium DOHC L37 Northstar V8 engine. Throughout its existence, the STS was Cadillac's highest-priced sedan. Worldwide, the STS is Cadillac's flagship model. In the United States and Canada, the STS is positioned between the mid-size CTS and larger DTS, but is priced above the latter.
