The Cadillac STS (an initialism of Seville Touring Sedan) is a mid-sized luxury 4-door sedan manufactured and marketed by General Motors from 2004 to 2011 for the 2005 to 2011 model years. A version of the STS was marketed in China as the SLS through 2013.

It was equipped with a six-speed automatic transmission with performance algorithm shifting and driver shift control.[6]

The STS succeeded the Cadillac Seville,[1] which has been available beginning with model year 1987 in a performance-oriented trim, marketed as the STS, for Seville Touring Sedan.

While smaller than the full-size DTS, the more expensive STS was the flagship sedan of the Cadillac brand.[7]

2005–2007

The front wheel drive Seville was retired in 2004, succeeded by the "STS," using the rear wheel drive GM Sigma platform. The first Cadillac sedan to be offered with All wheel drive, the STS retained the Seville's high-performance Magnetic Ride Control suspension. The STS was assembled at GM's Lansing Grand River facility in Lansing, Michigan along with the smaller CTS sedan.

Available engines were a 3.6 L High Feature LY7 V6 with 255 hp and 252 lbft and the 4.6 L Northstar LH2 V8 which puts out 320 hp and 315 lbft in the STS. All engine models feature dual overhead camshafts with variable valve timing. Remote ignition is standard, as is a push-button starter borrowed from the Corvette C6.

Overall length was down 5" to 196.3", yet wheelbase grew by 4" to 116.4 in, resulting in increased interior space.

Cadillac offered the STS in six trims, with the STS-V trim added for 2006:

A heads-up display/adaptive cruise control package with road-sensing HID Xenon headlights was optional with the 1SG trim for early 2004 models. This package became a V8 option for 2005. A 300-watt, 15-speaker, Bose Dolby 5.1 Surround Sound touchscreen navigation system with MP3 playback capability, XM satellite radio, Bluetooth connectivity, in-dash 6-disc DVD changer (the first vehicle to ever offer an in-dash DVD changer,) video input jack, and screen tilt feature is standard for all Luxury Performance (1SC, 1SF) trims (which this system would later be shared with the third generation 2007-2014 GMT926/36/46 Escalade.) The 1SF trim also adds ventilated front seats as standard equipment. Other options included a one-touch power tilt/slide sunroof, a High Performance brake/tire package, and Tuscany leather interior.

AWD was introduced as a V8 option for early 2004 cars, and was added to the V6 for 2005. The AWD option can be identified by the "STS4" trunklid badge, and a narrowed front passenger floorboard (to allow space for the transfer case components.) The STS-V is not available with AWD.

Base pricing at launch ranged from US$40,575 for the V6 model to US$47,025 for the V8.

STS-V

The Cadillac STS-V is a high-performance executive car of the V-Series introduced at the 2005 Detroit Auto Show, and was available for sale in late 2005.

The STS-V uses a supercharged 4.4 L version of the Northstar V8, producing 469 hp and 439 lbft. This engine is mated to a driver-adjustable GM automatic transmission with two shifting modes, larger brakes by Brembo, larger 10 spoke alloy wheels (18"x8.5" front, 19"x9.5" rear), Pirelli run-flat tires, a faster steering ratio, and a stiffer suspension than the standard STS. The engine block and cylinder heads are aluminum, the camshafts are cast iron, and the crankshaft is forged steel. Suspension is fully independent and there are four settings for the traction control system and stability control. Also different from the standard STS, the STS-V has a cooler for the rear differential oil located on the underside of the car behind the 3rd member.

The STS-V had a 0-60 mph acceleration time of 4.6 seconds and a 13.2 second quarter mile time.[15]

The STS-V's primary visual difference from the standard STS was a wire mesh grille and a 'power-dome' hood as well as six lug wheels normally seen only on larger SUVs, trucks and pickups. In addition to the grille, the front differences include the bumper, the fog light and turning signal cluster, and the hood which is slightly domed to fit over the supercharger. In the rear, the bumper is different from the standard STS and includes a wire mesh insert at the bottom which is made of the same mesh material used in the front grille. The rear spoiler is taller and wider, and encompasses the third brake light.

For the interior, the STS-V also has upgraded leather and Ultrasuede[16] trim, by the German company Dräxlmaier, in either Ebony and Gray, both of which are offered on the standard STS as well, and a two-tone Ebony/Tango Red scheme which was unique to the STS-V.
