Cadillac STS

The STS (Seville Touring Sedan) is a luxury car sold by Cadillac.

Origins

The STS is the successor to the "import fighter" Cadillac Seville. That car used the STS name, standing for "Seville Touring Sedan" on upscale performance-oriented versions from at least 1988. In 1992, Cadillac split the Seville line into STS and more luxury-oriented SLS (for "Seville Luxury Sedan") trim lines. The next year, the STS got Cadillac's then-new Northstar System, including the aluminum DOHC L37 "Northstar" V8 engine. Throughout its existence, the STS was Cadillac's highest-priced sedan model.

2005

The front wheel drive Seville was retired in 2004, replaced by an entirely new STS model based on the rear wheel drive GM Sigma platform. All wheel drive is offered as an option, the first Cadillac sedan to be available with this drive system.

Engines are a 3.6L High Feature LY7 V6 with 255hp (190kW) and 252ft·lbf (342N·m) and the 4.6L Northstar LH2 V8 which outputs 320hp (239kW) and 315ft·lbf (427N·m) in the STS. Remote ignition is standard.
