Cadillac STS Used Parts Online

The STS (Seville Touring Sedan) is a midsize luxury car manufactured and sold by Cadillac. The STS is the successor to the 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 less performance-oriented SLS (for "Seville Luxury Sedan") trim lines. The next year, the STS got 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 model. 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, and is priced above the DTS. 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. The Cadillac STS is assembled at GM's Lansing Grand River facility in Lansing, Michigan along with the smaller Cadillac CTS sedan and Cadillac SRX crossover SUV. As of 2007, engines are a 3.6 L High Feature LY7 V6 with 255 hp (190 kW) and 252 lb-ft (342 N-m) and the 4.6 L Northstar LH2 V8 which puts out 320 hp (239 kW) and 315 lb-ft (427 N-m) in the STS. All engine models feature dual overhead camshafts with VVT. Remote ignition is standard. Cadillac now has different packages and car models, which no longer support this option. Wheelbase is 116.4 in (2957 mm), though overall length is shorter than the Seville. Interior space is greater than its predecessor, though. A heads-up display is optional, as is a 300 Watt Bose stereo system with MP3 capability. 2006 The 2006 V-series STS-V was introduced at the 2005 Detroit Auto Show. It features a supercharged 4.4 L version of the Northstar V8, along with handling upgrades. This engine is certified by the SAE to produce 469 hp (350 kW) and 439 lb-ft (595 N-m). In 2006, Cadillac introduced a stretched STS called the SLS. It is assembled by Shanghai GM, and in 2007 it was showed at the Middle East International Motor Show in Dubai. The SLS adds 3.9 inches (99.1 mm) of rear-seat legroom and has a different interior. 2008 For 2008, the STS has been updated. Changes include a refreshed exterior, with styling cues resembling the 2008 CTS, such as larger, more aggressive grille and chrome fender vents. The interior has also been updated, with new materials and a new steering wheel, though the overall interior design remains the same, despite previous rumors of an all-new interior similar to that of the Chinese-market SLS. The standard powertrain is now a direct-injected 3.6 L V6 mated to a six-speed automatic transmission, which in the STS will produce 302 horsepower (225 kW) and 272 lb-ft (369 N-m) of torque. It also offers enhanced safety features, including a lane departure warning system, a blind spot monitoring system, and an improved version of GM's StabiliTrak stability control system, which can now operate the steering system in addition to the brakes to help correct a skid. Additionally, options previously limited to the V8 model (such as HID headlamps and heads-up display) are now available with the V6. The 2008 Cadillac STS debuted at the 2007 New York Auto Show.
