Facelift Buick LaCrosse (US, 2009; rear view)

The LaCrosse debuted in late 2004 as a 2005 model, replacing the Century and Regal. The name was borrowed from the 2000 Buick concept of the same name, referencing the sport of lacrosse.

Using the MS2000 variant of the 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 base CX and mid-level CXL forms, and a 3.6 L HFV6 V6 in the top line CXS model. The CXS was replaced by the Super in the US market for the 2008 model year.[13] Sales of the CXS continued in Canada until January 1, 2008.[14]

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’s Oshawa Assembly South.

LaCrosse models featured an acoustic approach, marketed by Buick as QuietTuning, to reduce, block and absorb cabin noise. Features of the system included acoustical windshield and front side glass laminate; 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.

The first generation LaCrosse was marketed in Canada as the Buick Allure, as the verb crosser is a French Canadian vulgarity that can mean either "masturbation" or "scam".[15][16]

The final first-generation LaCrosse was manufactured on December 23, 2008.

The LaCrosse received a facelift for 2008. The vehicle's front end design was based on the Buick Velite concept, which was later used by the Chinese LaCrosse.[17] Ventiports were deleted on all models equipped with the Series III 3800 V6.

All trim levels received a chrome exterior appearance package, factory remote start feature, XM Satellite Radio, telescoping steering wheel column, redundant steering wheel controls and dual-zone climate control as added standard equipment. CX added a leather-wrapped steering wheel, theft deterrent system, illuminated vanity mirrors, driver information center personalization and more.[18]

For the 2009 model year, the last of the first generation, heated outside rearview mirrors became standard on all models; a 60/40 split folding rear seat added to Driver Confidence Package; Bluetooth became available on all models with includes integrated steering wheel controls; 16-inch painted aluminum wheel were standard on CX models and 17-inch chrome-clad wheels became available on CX models.

2009 Buick LaCrosse Super

Buick offered the Locrosse Super for model years 2008-2009, engineered by the GM Performance Division; resurrecting the Super nameplate from Buick's 1930s-1950s model; and positioned as a higher-performance model.

The Super's LS4 5.3 L V8 engine featured Active Fuel Management technology,[19] able to use four of its eight cylinders to save fuel. This engine was shared with the Grand Prix GXP, Impala SS, and Monte Carlo SS.

Mechanically, the Super featured recalibrated steering and chassis tuning with Bilstein monotube struts; magnetically sensitive variable assist power steering, marketed as Magnasteer; larger rotors at all four disc brakes; full-range, powertrain- and brake-modulated traction control; revised suspension tuning with standard electronic stability control, marketed as Stabilitrak; dual 3.5-inch-diameter chrome exhaust tips and 18-inch cast aluminum wheels with P235/50R18 all-season tires.

Exterior features included fender Ventiports, rear spoiler, revised front fascia incorporating a chrome lower grille trim and chrome bezels for projector beam fog lights, rocker moldings, and revised rear fascia with integrated park assist sensors. Interior features included a Super-badged, blue-faced instrument cluster, faux chestnut wood trim, enhanced front seatback bolstering, split fold-down rear seats, leather seating surfaces with embossed inserts marketed as Dream Weave and optional bluetooth wireless technology. Interior colors were Platinum and Mocha Brown, while exterior color choices were brown, black, red and silver — marketed as Mocha Brown Metallic, Black Onyx, Red Jewel Tincoat, and Platinum Metallic.

The Super model was noted for its factory top speed of 150 mph (240 km/h) and 0–60 mph times of 5.7 seconds — and was discontinued in 2009.

The LaCrosse received a Good overall score in the Insurance Institute for Highway Safety's frontal impact crash test and a Marginal overall rating in the side impact test.[20] Injury measurements for the side-impact crash test include a Poor mark for the driver's torso and a Marginal score for the driver's pelvis and leg. Side airbags are limited to the curtain type for both front and rear rows; the torso-type side airbag is unavailable.[21] 2007 models also earned one out of five stars in a National Highway Traffic Safety Administration side-impact crash test.[22] The IIHS also found that the 2006–08 model year LaCrosse had the second-highest fatality rate in the large four-door car class; only the Buick Lucerne fared worse.[23]

Shanghai GM introduced the Buick LaCrosse in February 2006, as a more upscale companion to its Buick Regal sedan.[25] Designed by Shanghai GM's Pan Asia Technical Automotive Center (PATAC), the Chinese LaCrosse is based on the same architecture as the North American model, but possesses different exterior and interior designs, and a different engine lineup. The car is also built in Taiwan by a joint Yulon-GM venture.

The 2.4 L Ecotec four-cylinder replaced the 3.0 V6 as the standard engine on the CX model in the first quarter of 2010.[36] The 3.6 L V6 continues to be an option on the CX and front-wheel drive CXL and standard on the CXS and all-wheel drive CXL.[37]

All V6 models are equipped with the Hydra-Matic 6T70 6-speed automatic transmission.

The New York Times said the new LaCrosse combined design elements from classic American cars of the 1930s and 1950s with traditional Chinese aesthetic elements:[33] U.S. News & World Report aggregated the following ratings based on numerous reviews of the models years, also for the 2016 model year. Results of the analysis were given on a scale of 1 to 10, where a higher number indicates positive reception. The overall result for the 2016 model year was 8.7, critics' rating 8.8, performance 8.1, interior 8.4, and safety 9.7.[39]

The 2010 Buick LaCrosse CXS is the first North American car to incorporate a front suspension design, marketed as HiPer Strut, designed to improve ride and handling and reduces torque steer.[40] The Buick LaCrosse CXS includes a system marketed as Real Time Damping that adjusts the damping forces of the shocks and struts for improved ride and handling.[41]

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 year 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.[42][43]

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

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 is 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 Hydramatic 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 2.4-liter 4-cylinder, the BAS-II system allows for engine start/stop operation when the vehicle isn't moving and allows for complete fuel cut off to the engine during deceleration.[44] The LaCrosse was sold in Mexico starting in 2010, as the Buick brand returned to the country after 13 years of absence.[45]

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

The 2nd generation LaCrosse debuted to the Canadian market at the 2009 Montreal International Auto Show as the Buick Allure,[46] and soon after production began, General Motors Canada renamed the Allure to LaCrosse, to correspond with the car's global marketing.[16] GM Canada has offered existing Allure owners the option to change nameplates to LaCrosse.[47]

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 3.0-liter V-6 engine, six-speed automatic transmission) was unveiled at the 2010 Busan International Motor Show.[48]

Production began on August 9, 2010 at GM Daewoo's factory in Bupyeong, Incheon. Market launch began in September 2010. Early model includes a model with 3.0-liter engine (from 2010 Buick LaCrosse) in mid-September, followed by two models each with 2.4-liter engine in October.[49][50]

The Alpheon was discontinued in 2015, after monthly sales fell below 500 cars. GM Korea replaced it with the Chevrolet Impala.[51]

The Roewe 950 is a licensed restyled Chinese version of the Buick LaCrosse produced by Roewe of SAIC. It is sold alongside the Buick LaCrosse in China, and has a price range similar to that of the LaCrosse. The sheet metal, while similar in appearance, is unique to the Roewe.

In late February 2012, the Chinese government took the Buick LaCrosse (along with all other foreign vehicles) off of the list of vehicles approved for government procurement.[52] Though popular among government officials the LaCrosse also thrives via private purchases. Effects on sales remains to be seen.

Buick unveiled a revised 2014 LaCrosse at the 2013 New York Auto Show. Redesigned front and rear fascias, new wheel designs, a reconfigurable 8 inch TFT instrument cluster, semi-aniline leather seating, and radar- and camera-based safety features such as forward collision alert and side blind zone alert highlight the changes for this mid-cycle refresh.

Production of North American models moved from Oshawa to the Fairfax Assembly plant in Kansas City, Kansas, where it runs down the same production line as the Chevrolet Malibu.[53] Delivery of 2010 year models was delayed a few weeks in order to assure quality control.[54] Production for China started a month later.

The 2017 LaCrosse received a Top Safety Pick in the Insurance Institute for Highway Safety's Crashworthiness test and a Poor rating for headlights, which prevented a Top Safety Pick Plus.[60] The LaCrosse comes standard with 10 air bags including front air bags, roof rail-mounted head-curtain air bags, seat-mounted side-impact air bags for both front and rear outboard seat passengers, and knee air bags for front seat passengers. Additional standard safety features include Ultra-sonic rear parking assist, and backup camera. Optional safety features include a following distance indicator, forward collision alert, forward collision braking, front pedestrian detection, blind spot detection, lane keeping assist, and rear-cross traffic alert.[61]

Car and Driver's said the Lacrosse had an "elegant exterior, much-improved interior materials, impressive ride and handling with up level suspension,"[62] while U.S. News & World Report listed the 2017 LaCrosse as a Finalist for Best Large Car for Families.[63] Motor Trend said "the car drops about 300 pounds and rides on a new platform, which contributes to a better driving experience and a much quieter ride. Buick also separates the LaCrosse from most competitors by offering all-wheel drive on the highest trim level," and listed the Kia Cadenza, Nissan Maxima, Chrysler 300, and Lexus ES as competitors.[64]

Consumer Reports was critical of the gear selector, saying "our biggest gripe about the controls is the new electronic gear selector. Drivers used to a traditional PRNDL configuration—in other words, those drivers who kept the lights on for Buick for many years—will be puzzled, if not angered."[65] In addition, reviewers were critical of the sticker price on top trim, heavily optioned models with Bloomberg saying "by the time you spend the $48,395 it costs to get the LaCrosse to this level, you're creeping into Audi/BMW/Mercedes territory."[66]

The Buick LaCrosse was one of six vehicles GM discontinued after the 2019 model year amid a global restructuring effort. The discontinuation of the LaCrosse affected the North American market[67][68] and Buick will continue to manufacture the LaCrosse in China, where the sedan remains a best seller.[69] Production of the Buick LaCrosse for North America ceased on February 15, 2019.[55]

2019 Buick LaCrosse facelift (China)

A facelift was introduced for the 2019 model year in the Chinese market, with the facelifted LaCrosse featuring a new 2.0-liter turbo engine to the powertrain options. The new 2.0-liter turbo engine is one of GM’s eighth-generation Ecotec engines and delivers a maximum output of 237 hp and 350 N-m (258 lb-ft) of torque. The 2019 LaCrosse is available with a nine-speed Hydra-Matic automatic transmission with an average fuel consumption of 6.9 liters per 100 kilometers (34 miles per gallon).[70] Trim levels for the New LaCrosse model are known as the 652T Elite, 652T Luxury and 652T Distinguished.[71] From 2021 onwards, the 552T trim level was available where a 1.5 litre turbocharged engine was also introduced as standard.
