The Buick LaCrosse is a four-door, front-wheel-drive sedan manufactured by Buick since model year 2005, and marketed variously across four generations for the North American and Chinese markets.

The first-generation LaCrosse replaced the Century and Regal in North America beginning for model year 2005 as a five- or six-passenger, four-door, front-wheel-drive, V6-powered sedan using GM's mid-size W platform—and marketed in Canada as the Buick Allure. Notably, the first generation was also offered with a V8 engine, as a high-performance sub-model marketed as the LaCrosse Super (2008–2009). LaCrosse production and marketing began for China with model year 2006.

The second-generation LaCrosse was introduced for 2010 as a larger premium sedan for North American and Chinese markets{{cite web|url=http://www.thecarconnection.com/overview/buick_lacrosse_2010|title=2010 Buick LaCrosse - Review|work=The Car Connection Review|access-date=September 17, 2017}}{{cite web|url=http://www.newcartestdrive.com/reviews/2010-buick-lacrosse/|title=2010 Buick LaCrosse|work=New Car Test Drive review of redesigned upscale version|date=March 13, 2010|access-date=September 17, 2017}} using a long-wheelbase (LWB) variant of the Epsilon II platform shared with the Cadillac XTS—and available solely as a five-passenger sedan with a range of four- and six-cylinder engines.

The third generation was introduced for North America and China for model year 2017 using the GM Epsilon platform shared with the Chevrolet Impala, notably offering a mild hybrid powertrain combining {{convert|20|kW|hp|adj=on}} electric and 2.5-liter Ecotec gasoline engine. North American production ended with the third generation, with model year 2019; however, it continued to be offered in China, with a 2019 facelift.

The fourth-generation LaCrosse, launched in 2023, is currently manufactured and marketed solely in China. It is powered by a turbocharged 1.5-liter or 2.0-liter four-cylinder engine.

Background and name

In 2000, Buick showcased a LaCrosse concept featuring styling features that referred to Buicks of the late 1940s including a descending swage line (featured on Buicks starting in 1940 and sporadically until the 1970s) and front fender port holes. Unique features included a removable rear roof and trunk panel (converting the trunk into a truck bed) and voice recognition instead of traditional switches for basic interior functions. The Buick LaCrosse concept was based on the GM G body shared with the Buick Park Avenue.{{Cite web|url=https://www.auto123.com/en/news/2000-buick-lacrosse-concept/43391/?page=2|title = 2000 Buick LaCrosse Concept Editor's Review | Car News | Auto123| date=9 December 2002 }}

As the Buick nameplate, the term lacrosse refers to the sport. Out of caution, GM chose to market the model in Canada as the Allure because the words "faire la crosse (make the cross)" are a slang Québecoise phrase meaning "to masturbate"—even though the words la crosse themselves translate as "the cross" in French and are not generally problematic.{{cite news|url=http://auto.lapresse.ca/actualites/201109/12/01-4442047-la-buick-lacrosse-un-nom-pas-dallure.php |title=La Buick LaCrosse ?

The first generation LaCrosse debuted in late 2004 as a 2005 model, replacing the Century and Regal—solely as a four-door, front-drive sedan. The nameplate was borrowed from the 2000 Buick concept of the same name.

Using the MS2000 variant of GM's long-lived front-drive W-body platform, the LaCrosse was initially available with two powerplants and three trim levels: a 3.8 L 3800 Series III V6 available in CX and mid-level CXL, and a 3.6 L HFV6 V6 in the CXS model. The CXS was replaced by the LaCrosse Super sub-model in North American markets, with the CXS available partly through model year 2008.{{cite web|url=http://media.gm.com/us/buick/en/product_services/r_cars/r_c_lacrosse/08index.html |title=2008 Buick LaCrosse & LaCrosse Super |work=GM Media Online |date=August 1, 2007 |access-date=2009-09-13 |url-status=dead |archive-url=https://archive.today/20081008080926/http://media.gm.com/us/buick/en/product_services/r_cars/r_c_lacrosse/08index.html |archive-date=October 8, 2008 }} Sales of the CXS continued in Canada until January 1, 2008.{{Cite web |title=2008 Buick Allure |url=https://media.gm.com/dam/Media/documents/CA/Archives/EN/Vehicles/buick/2008Allure.html |access-date=2023-11-05 |website=GM Media Online Archives}}

Structurally, the engine cradle, previously steel, was replaced by a stiffer, stronger, and lighter extruded aluminum cradle, weighing 20 pounds less. The LaCrosse used more high-strength steel than its predecessors, as well as a magnesium cross-car beam behind the instrument panel, another cross-car beam behind the rear seats, steel reinforcements in the rocker panels, interlocking door latch system, high-strength steel door beams, and a double-thick Quiet Steel floor pan and firewalls.

CX and CXL models used the 4T65-E automatic transmission and Super models used the 4T65-E HD variant. The LaCrosse, along with all other GM vehicles powered by the 3.8 L V6, became the first SULEV-compliant vehicles for 2006. All models were manufactured at GM Oshawa Assembly. Front driver and passenger airbags were standard, with optional side curtain airbags — which became standard for model year 2006.

All LaCrosse models featured an acoustic package, marketed by Buick as QuietTuning, to reduce, block, and absorb cabin noise. Features of the system included acoustical windshield and front side laminated glass; steel laminate on the front-of-dash body area; expanded baffles in the roof pillars; melt-on sound deadeners throughout the entire lower body structure; and sound-absorbing material throughout the engine, passenger, and cargo compartments.

Buick offered the LaCrosse as a five-passenger sedan, using front bucket seats and a console-mounted shifter, the console integrating with the upper instrument panel. At extra cost, a six-passenger configuration was available where the front seats shared a center flexible console that could fold up for a sixth passenger or fold out to provide a storage console, the transmission using a column-mounted shifter.

Regarding its styling, noted automotive journalist Warren Brown described the Lacrosse as a "delightful rendition of the automobile as functional art."{{cite news

The final first-generation LaCrosse was manufactured on December 23, 2008.{{citation needed|date=January 2009}} North American sales reached roughly 290,000 for model years 2005–2009, and the 2009 model was the last GM car using the company's noted and long-lived 3800 V6 engine.

The LaCrosse received a facelift for 2008 with the vehicle's revised front design based on the Buick Velite concept and later used by the first generation Chinese LaCrosse.{{cite web|url=http://www.autoblog.com/2006/11/26/chinas-buick-lacrosse-is-cooler-than-ours/|title=China's Buick LaCrosse is cooler than ours|author=Nunez, Alex|work=Autoblog|date=November 26, 2006|access-date=September 17, 2017}}

All trim levels received a chrome exterior appearance package, factory remote start feature, XM Satellite Radio, telescoping steering wheel column, redundant steering wheel and climate control as added standard equipment (audio only post-MY 2006). CX included a leather-wrapped steering wheel, theft-deterrent system, illuminated vanity mirrors, driver information center personalization, and hydraulic struts supporting both the engine hood and trunk lid.{{cite web|url=http://www.autoblog.com/2007/03/27/new-york-preview-2008-buick-lacrosse-gets-facelift/|title=New York Preview: 2008 Buick LaCrosse gets facelift|author=Neff, John|work=Autoblog|date=March 27, 2007|access-date=September 17, 2017}}{{cite web

Resurrecting the Super nameplate from Buick's 1930s–1950s model, the model featured minor interior and exterior tweaks as well as a 5.3-liter, 300-hp V8 engine shared with the Pontiac Grand Prix GXP and Chevrolet Impala SS, and Monte Carlo SS—engineered under the direction of former Corvette engineer John Heinricy with the GM Performance Division.{{cite web

The Super's LS4 5.3 L V8 engine made {{convert|300|hp|kW|0|abbr=on}} and {{convert|323|lbft|0|abbr=on}}, used premium fuel, and featured variable displacement technology (marketed as Active Fuel Management),{{cite web|url=http://carsandracingstuff.com/library/articles/0424.php|title='Super' Buicks: The Return|work=The Crittenden Automotive Library|access-date=September 17, 2017}} capable of deactivating four of its eight cylinders to save fuel. It was noted for its factory top speed of {{convert|150|mi/h|km/h|abbr=on}} and a 0–60 mph time of 5.7 seconds.

The Super used the heavier duty 4T65-E HD four-speed automatic transmission, magnetically sensitive variable-effort power steering (marketed as Magnasteer), and a steering rack with closer-fitting gear teeth, tighter bushings, and a stiffer torsion rod controlling the variable-effort power assist.{{cite web

The exterior used faux vents and a falling swage line, marketed respectively as VentiPorts and Sweepspears—and making reference to styling elements Buick had incorporated in various forms since introducing them in 1949.

The second-generation used a long-wheelbase (LWB) variant of the Epsilon II platform, shared with the Opel Insignia, 2010–2012 Saab 9-5, and the Cadillac XTS.[http://www.leftlanenews.com/buick-lacrosse-invicta.html 2010 Buick Lacrosse revealed (with video)] – Left Lane News The design was based on 2008 Buick Invicta concept, and replaces both the Chinese and North American models.

=Technology and features=

The 2010 Buick LaCrosse CXS was the first North American car to incorporate a front suspension design, marketed as HiPer Strut, designed to improve ride and handling while reducing torque steer.{{cite web|url=http://media.gm.com/content/media/us/en/news/news_detail.brand_buick.html/content/Pages/news/us/en/2010/Mar/0324_hiper_strut |title= Buick LaCrosse's Innovative HiPer Strut Suspension Delivers Improved Ride And Handling |publisher=Media.gm.com |date=March 24, 2010 |access-date=2010-06-12}} The Buick LaCrosse CXS included a system marketed as Real Time Damping that adjusts the damping forces of the shocks and struts for improved ride and handling.{{cite web |url=http://www.buick.com/vehicles/current-vehicles/lacrosse/features-specs/trims.html |archive-url=https://web.archive.org/web/20101220143926/http://www.buick.com/vehicles/current-vehicles/lacrosse/features-specs/trims.html |url-status=dead |archive-date=2010-12-20 |title=2012 LaCrosse Luxury Car Specs and Features |publisher=Buick |access-date=2012-01-08 }}

The 2010, 2012, and 2013 models lacked an interior trunk release mechanism. The trunk was only accessible using the key fob (remote keyless entry) or a touch sensor between the trunk lid and the license plate. The 2011 model added a remote release button at the left of the steering wheel on the instrument panel. The 2014 model refresh returned the trunk release button to LaCrosse but placed it on the driver door.{{Cite news|url = https://www.foxnews.com/auto/buick-lacrosse-vs-buick-regal|title = Buick LaCrosse Vs Buick Regal|last = Nunez|first = Alex|date = 10 Sep 2010|work = Fox News|access-date = 28 Apr 2015|url-status = live|archive-url = https://web.archive.org/web/20150601131134/http://www.foxnews.com/leisure/2010/09/09/buick-lacrosse-vs-buick-regal/|archive-date = 2015-06-01}}{{Cite web|url = http://buickforums.com/forums/threads/21272-Opening-trunk-on-a-LaCrosse|title = Buick Forum: Opening trunk on a LaCrosse|date = 30 May 2011|website = Buick Forum|publisher = Jelsoft Enterprises Ltd.}}

==eAssist==

The 2012 LaCrosse features a new mild hybrid as its base model. Dubbed eAssist, the 2012 LaCrosse introduced GM's second-generation belted-alternator starter system. The non-hybrid 4-cylinder was no longer offered. The system consists of a 115-volt lithium-ion battery pack, a 15 kW electric motor capable of adding 15 horsepower of assist while accelerating, and the next-generation 6T40 GM Hydra-Matic transmission with reduced friction components over the previous generation. The eAssist LaCrosse delivers a class leading fuel economy of 25 mpg city and 36 mpg highway. In addition to providing additional power to the 182 hp 2.4L 4-cylinder, the BAS-II system allows for engine start/stop operation when the vehicle is not moving and allows for complete fuel cutoff to the engine during deceleration.{{cite web|url=http://www.cheersandgears.com/topic/73386-understanding-the-2012-buick-lacrosse-with-eassist-system/ |title=Understanding the Technology behind the Buick LaCrosse eAssist |publisher=CheersandGears.com |date=2010-12-05 |access-date=2010-12-05}}

=Korean market: Alpheon=

The Alpheon was a localized version of the Buick LaCrosse for the South Korean market. Alpheon was a standalone brand from GM Korea. The cars were additionally fitted with amenities such as controls in the rear armrest, mood lights and more. A version of the vehicle (with 3.0L V6 engine mated to a six-speed automatic transmission) was unveiled at the 2010 Busan International Motor Show.{{Cite web|url=https://www.autoblog.com/2010/04/30/buick-lacrosse-rebranded-as-daewoo-alpheon-in-south-korea/|title=Buick LaCrosse rebranded as Daewoo Alpheon in South Korea|website=Autoblog}}

Production began on August 9, 2010, at GM Daewoo's factory in Bupyeong, Incheon. Market launch began in September 2010. Early models included one with a 3.0-liter engine (from the 2010 Buick LaCrosse) in mid-September, followed by two models each with a 2.4-liter engine in October.[http://english.chosun.com/site/data/html_dir/2010/08/10/2010081000322.html GM Daewoo Starts Production of Alpheon Luxury Sedan] in The Chosunilbo, 10 August 2010.{{cite web|url=http://www.gminsidenews.com/forums/f13/gm-daewoo-announces-alpheon-luxury-sedan-91423/ |title=GM Daewoo Announces Alpheon Luxury Sedan – GM Inside News Forum |publisher=Gminsidenews.com |date=2010-04-28 |access-date=2010-06-12}}

The Alpheon was discontinued in 2015, after monthly sales fell below 500 cars.

=Chinese market: Roewe 950=

The Roewe 950 was a {{citation needed span|licensed restyled|date=March 2023}} Chinese version of the Buick LaCrosse produced by Roewe of SAIC. It was sold alongside the Buick LaCrosse in China, and had a price range similar to that of the LaCrosse. The sheet metal, while similar in appearance, was unique to the Roewe.

In late February 2012, the Chinese government removed the Buick LaCrosse (along with all other foreign vehicles) from the list of vehicles approved for government procurement.{{cite web |url=http://www.autoblog.com/2012/02/28/china-issues-list-of-approved-vehicles-for-government-purchase/ |title=China issues list of approved vehicles for government purchase, excludes imports for first time |first=Jonathon|last=Ramsey |work=Autoblog |date=February 28, 2012 |access-date=2012-05-16}} Though popular among government officials, the LaCrosse also thrived via private purchases.

Buick unveiled a revised 2014 LaCrosse at the 2013 New York Auto Show. Redesigned front and rear fascias, new wheel designs, a reconfigurable eight-inch TFT LCD instrument cluster, semi-aniline leather seating, and radar- and camera-based safety features such as forward collision alert and side blind zone alert are among the most notable changes for this mid-cycle refresh.

For 2016, the LaCrosse added a new Sport Touring Edition which included unique 18" aluminum black pocket wheels, and a rear lip spoiler.

The platform switch and use of high-strength steels reduced weight by about {{convert|300|lb|kg}}, despite slightly growing in length and width.

The car was powered by a GM Small Gasoline Engine and GM Ecotec engine in China for tax credit purposes and by a fourth-generation GM High Feature engine in North America. Since 2018, the LaCrosse came standard with an eAssist drivetrain, consisting of a mild hybrid {{convert|20|kW|hp|adj=on}} electric and 2.5-liter Ecotec gasoline engine sending power to the front wheels through a 6-speed automatic transmission.{{Cite web | url=https://media.buick.com/media/us/en/buick/home.detail.html/content/Pages/news/us/en/2017/jun/0605-2018-lacrosse.html | title=Light Electrification Leads 2018 Buick LaCrosse Updates | date=5 June 2017 }}

In order to make room for an upcoming new product in the Kansas City facility, the production of the LaCrosse was moved from GM Fairfax Assembly to Detroit/Hamtramck Assembly.

The main difference between the North American and Chinese model LaCrosse was the drive system. Models sold in the Chinese market were front-wheel drive vehicles only, compared to their American counterparts which were available in front-wheel drive or all-wheel drive.
