The '''Cadillac STS''' (an initialism of '''Seville Touring Sedan''') is a [[Mid-size car|mid-size]]d [[luxury car|luxury]] 4-door [[sedan (car)|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.<ref name=6speed>[http://media.gm.com/us/powertrain/en/news/press_kits/05naias_kit/ GM POWERTRAIN LAUNCHES NEW HYDRA-MATIC SIX-SPEED AUTOMATIC TRANSMISSION] {{webarchive|url=https://web.archive.org/web/20090523111630/http://media.gm.com/us/powertrain/en/news/press_kits/05naias_kit/ |date=2009-05-23 }}. ''GM.com'' press release, January 10, 2005. Retrieved on August 1, 2009.</ref>

The STS succeeded the [[Cadillac Seville]],<ref name="newbury2006"/> 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 [[Cadillac DTS|DTS]], the more expensive STS was the flagship sedan of the Cadillac brand.<ref>{{Cite web|url=http://www.autozine.org/Archive/GM/old/STS.html|title=Cadillac STS|website=www.autozine.org|access-date=2019-11-22}}</ref>

== Safety ==
The Cadillac STS was rated with a four star frontal and five star rear passenger crash test rating from the [[National Highway Traffic Safety Administration]].<ref>{{cite web|url=http://www.safercar.gov/ |title=Safecar.gov |publisher=Safercar.gov |access-date=2011-04-25}}</ref>  It was given an overall "Good" score in the [[Insurance Institute for Highway Safety]] frontal crash test and an "Acceptable" rating in the side impact test.<ref name="iihs.org">{{cite web |url=http://www.iihs.org/ratings/rating.aspx?id=242 |title=IIHS-HLDI: Cadillac STS |publisher=Iihs.org |date=2008-11-25 |access-date=2009-08-22 |archive-date=2010-04-08 |archive-url=https://web.archive.org/web/20100408022321/http://www.iihs.org/ratings/rating.aspx?id=242 |url-status=dead }}</ref>  In the side impact test injury measurements to the driver's pelvis was rated "Poor" and for the torso "Acceptable."<ref name="autogenerated1">{{cite web |url=http://www.iihs.org/ratings/rating.aspx?id=828 |title=IIHS-HLDI: Cadillac STS |publisher=Iihs.org |date=2008-11-25 |access-date=2009-08-22 |archive-date=2010-04-08 |archive-url=https://web.archive.org/web/20100408022419/http://www.iihs.org/ratings/rating.aspx?id=828 |url-status=dead }}</ref>

== 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 [[Cadillac CTS|CTS]] sedan.

Available engines were a 3.6&nbsp;L [[GM High Feature engine#LY7|High Feature LY7]] [[V6]] with {{convert|255|hp|kW|abbr=on}} and {{convert|252|lbft|N.m|abbr=on}} and the 4.6&nbsp;L [[Northstar engine series#LH2|Northstar LH2]] [[V8 engine|V8]] which puts out {{convert|320|hp|kW|abbr=on}} and {{convert|315|lbft|N.m|abbr=on}} 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 [[Chevrolet Corvette C6|Corvette C6]].

Overall length was down 5" to 196.3", yet wheelbase grew by 4" to {{convert|116.4|in|mm|0|abbr=on}}, resulting in increased interior space. 

Cadillac offered the STS in six trims, with the STS-V trim added for 2006:
*STS V6 (1SA)<br/>
*STS V6 Luxury (1SB)<br/>
*STS V6 Luxury Performance (1SC)<br/>
*STS V8 Luxury (1SE)<br/>
*STS V8 Luxury Performance (1SF)<br/>
*STS V8 Premium Luxury Performance (1SG)<br/>

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 Corporation|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 [[Cadillac Escalade|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 [[USD|US$]]40,575 for the V6 model to [[USD|US$]]47,025 for the V8.

== 2008–2011 ==
[[File:2008-2009 Cadillac STS.jpg|250px|thumb|left|2008–2011 Cadillac STS]]The STS for model year 2008 received minor exterior revisions, including a larger grille and chrome fender vents. The interior received revised materials and a new steering wheel.

The standard powertrain was a [[gasoline direct injection|direct-injected]] 3.6&nbsp;L [[V6 engine|V6]] mated to a six-speed [[automatic transmission]], which in the STS produced {{convert|302|hp|kW|abbr=on}} and {{convert|272|lbft|N.m|abbr=on}} of torque. Optional safety features included 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. Options previously limited to the [[V8 engine|V8]] model (such as [[HID headlamp]]s and [[Automotive head-up display]]) were available with the [[V6 engine|V6]]. The 2008 Cadillac STS debuted at the 2007 [[New York Auto Show]].<ref>{{cite web |url=http://news.windingroad.com/body-stylesmarket-segment/sedans/cadillac-ups-sts-horsepower-rating-to-302 |title= Magazines - Winding Road|website=news.windingroad.com |archive-url=https://web.archive.org/web/20070523102225/http://news.windingroad.com/body-stylesmarket-segment/sedans/cadillac-ups-sts-horsepower-rating-to-302 |archive-date=May 23, 2007}}</ref>

A 2010 update for the STS removed the GM badges, although early 2010 models still retained GM badging.<ref>{{cite web|url=http://www.detnews.com/article/20090825/AUTO01/908250320/1148/rss25 |title=GM to drop corporate logo from vehicles - Detroit News |publisher=The Detroit News |access-date=2011-04-25}}</ref>  For 2011, the V8 was dropped from the Cadillac STS lineup.<ref>{{cite web |url=http://blog.caranddriver.com/2011-gm-order-guide-changes-for-chevrolet-camaro-corvette-hhr-malibu-cadillac-sts/ |title=2011 GM Order Guide: Changes for Chevrolet Camaro, Corvette, HHR, Malibu; Cadillac STS |access-date=2010-04-30 |archive-date=May 3, 2010 |archive-url=https://web.archive.org/web/20100503032821/http://blog.caranddriver.com/2011-gm-order-guide-changes-for-chevrolet-camaro-corvette-hhr-malibu-cadillac-sts/ |url-status=dead }}</ref>

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

The STS-V uses a [[supercharged]] 4.4&nbsp;L version of the [[Cadillac Northstar engine#Supercharged|Northstar]] V8, producing {{convert|469|hp|kW|0|abbr=on}} and {{convert|439|lbft|Nm|0|abbr=on}}. 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 tire]]s, a faster steering ratio, and a stiffer [[Suspension (vehicle)|suspension]] than the standard STS. The [[engine block]] and [[cylinder head]]s 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-{{convert|60|mph|km/h|0|abbr=on}} acceleration time of 4.6 seconds and a 13.2 second quarter mile time.<ref>{{Cite news|url=http://www.caranddriver.com/comparisons/2006-bmw-m5-vs-2006-cadillac-sts-v-vs-2006-mercedes-benz-cls55-amg-comparison-test|title=2006 BMW M5 vs. Cadillac STS-V, M-B CLS55 AMG|last=Swan|first=Tony|date=January 2006|work=Car and Driver|access-date=May 4, 2017}}</ref>

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]]<ref>{{Cite web |title=2006 Cadillac STS-V Photo Gallery {{!}} Autoweb |url=https://www.autoweb.com/2006-cadillac-stsv-photo-gallery |access-date=2025-08-01 |website=www.autoweb.com}}</ref> 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.

[[File:Cadillac SLS facelift 01 China 2012-04-08.jpg|250px|thumb|left|2010–2013 Cadillac SLS]]
The Chinese-Spec SLS received a facelift at the end of 2009, and was sold as a 2010 model year. The grille, bumper and many other details were revised.

The SLS was priced from 448,000RMB to 828,000RMB  ($94,835 to $175,160 US - August 2022 exchange rate).<ref>{{Cite web|url=https://car.autohome.com.cn/config/spec/2656.html#pvareaid=3454541|title=【SLS赛威 2007款 4.6 旗舰型参数配置表】价格单_凯迪拉克_汽车之家|website=car.autohome.com.cn|accessdate=14 May 2023}}</ref>
