Origins [ edit ]

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 was Cadillac’s flagship model. In the United States and Canada. the STS in its day was positioned between the smaller mid-size CTS and larger full-size DTS. but was priced above the latter.

2005 [ edit ]

2005–2007 Cadillac STS

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 STS carries on the Magnetic Ride Control suspension, which has bragging rights as being the ‘fastest reacting suspension ever,’ before it was ever utilized on newer Corvettes and Ferraris .

Available engines were a 3.6#160;L High Feature LY7 V6 with 255#160;hp (190#160;kW) and 252#160;lb·ft (342#160;N·m) and the 4.6#160;L Northstar LH2 V8 which puts out 320#160;hp (240#160;kW) and 315#160;lb·ft (427#160;N·m) in the STS. All engine models feature dual overhead camshafts with VVT. Remote ignition is standard.

Although most 2005 and 2006 Cadillac STS models offer a 255#160;hp (190#160;kW) engine, an option for a 4.6#160;L 320#160;hp (239#160;kW) engine was available at the time through Cadillac’s performance packages. As of 2007, Cadillac now has different packages and car models, which no longer support this option.

Wheelbase was 116.4#160;in (2,957#160;mm), though overall length was shorter than the Seville. Interior space was greater than its predecessor. A heads-up display was optional, as was a 300-watt Bose stereo system with MP3 capability.

Base pricing started at US$ 40,995 (slightly higher than the DTS. which was longer but had front-wheel drive ), and extended to US$52,240 for the AWD V8 model.

2006 [ edit ]

The 2006 V-series STS-V was introduced at the 2005 Detroit Auto Show. It features a supercharged 4.4#160;L version of the Northstar V8. along with handling upgrades.

This engine is certified by the SAE to produce 469#160;hp (350#160;kW) and 439#160;lb·ft (595#160;N·m).

In 2006, Cadillac introduced a stretched STS called the SLS . It is assembled by Shanghai GM. and in 2007 it was shown at the Middle East International Motor Show in Dubai. The SLS adds 3.9 inches (99.1#160;mm) of rear-seat legroom and has a different interior with higher quality materials.

2008 [ edit ]

2008–2010 Cadillac STS

For 2008, the STS was updated. Changes included a refreshed exterior, with styling cues resembling the 2008 CTS. such as larger, more aggressive grille and chrome fender vents. The interior was updated, with new materials and a new steering wheel, though the overall interior design remained the same, despite previous rumors of an all-new interior similar to that of the Chinese-market SLS.

The standard powertrain was a direct-injected 3.6#160;L V6 mated to a six-speed automatic transmission. which in the STS produced 302 horsepower (225#160;kW) and 272#160;lb·ft (369#160;N·m) of torque. It also offered enhanced safety features, including a lane departure warning system developed by Mobileye. a blind spot monitoring system. and an improved version of GM’s StabiliTrak stability control system, which could 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) were available with the V6. The 2008 Cadillac STS debuted at the 2007 New York Auto Show. [ 8 ]

A 2010 update for the STS removed the GM badges, although early 2010 models still retained GM badging. [ 9 ] For 2011, the V8 was entirely dropped from the Cadillac STS lineup. [ 10 ]

Chinese Cadillac SLS [ edit ]

For the 2007 model year, the Chinese market received the Cadillac SLS. Compared to the STS, the SLS has a longer wheelbase, unique interior appointments, and a near-identical exterior appearance. Engine choices are the 2.8-liter V-6, 3.6-liter V-6 (the non-direct-injection version shared with the 2005-2007 STS V-6), and the same 4.6-liter Northstar V-8 as in the STS V-8. [ 11 ]

The Chinese-Spec SLS received a facelift at the end of 2009, and was sold as a 2010. The grill, bumper and many other details were revised. Shanghai-GM also introduced the OnStar system to the model.

Two SIDI engines were introduced, a 272#160;hp 3.0L and a 310#160;hp 3.6L. The SLS is priced from 448,000RMB to 698,000RMB.
