The LaCrosse made its debut in late 2004 as a 2005 model to replace the Century and Regal. Riding on a revised version of the W-body known as MS2000, the LaCrosse was initially available with two powerplant choices in 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. Power is routed to the front wheels via a 4T65-E automatic transmission (4T65-E HD on Supers).

The name was inspired by a Buick concept car of the same name shown in 2000 and also used as a reference to the sport of lacrosse, seen as popular with a younger, more active demographic to which Buick sought to market.

It was originally sold as Buick Allure in Canada because "la crosse" means 'self-love' (or 'swindle'[3]) in Quebec French slang.[4] It was once Buick's best-selling vehicle in Canada until 2008, when the Enclave became the brand's best-seller (which it remains as of 2010).

The LaCrosse, along with all other GM vehicles powered by the 3.8 L V6, became the first SULEV-compliant vehicles for 2006.

The last first-generation LaCrosse rolled off the assembly line on December 23, 2008.[citation needed]


The LaCrosse received a minor refresh for 2008. The vehicle's front end design was based on the Buick Velite concept, which was later used by the Chinese LaCrosse.[5] New body color choices included Scarlett Red, Gold Mist Metallic, Dark Mocha Metallic and Dark Slate Metallic.

All trim levels gained 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.[6]


2008 Buick LaCrosse Super

A new trim of the LaCrosse bearing the Super moniker debuted for 2008. The LaCrosse Super was positioned as a higher-performance model of the sedan with revised front end styling influenced by the 2004 Velite concept car, as well as 4 ventiports (reflecting a V8 engine under the hood), a rear spoiler, projector beam fog lights, Magnasteer, larger brakes, and revised suspension tuning with standard Stabilitrak. Interior changes included special Super badged cluster with blue face, a wood grain shift knob, and dream weave leather seating. Interior colors for the Super were Platinum and Mocha Brown, while exterior color choices were Mocha Brown Metallic, Black Onyx, Red Jewel Tincoat, and Platinum Metallic. Power came from the 5.3 L LS4 small-block V8 engine featuring Active Fuel Management technology,[7] which is routed to the front wheels. The combination of a V8 and front-wheel drive are not often utilized due to torque steer which is present in any front-wheel-drive car. This powertrain was also found on the Grand Prix GXPImpala SS, and Monte Carlo SS. The Super model was the fastest modern production Buick ever built, with a factory top speed of 150 mph (240 km/h), and 0-60 mph times of 5.7 seconds. Only the Buick GNX of the 1980s was given such performance ratings until the Super was introduced.


In the Insurance Institute for Highway Safety's crash tests the LaCrosse received a Good overall score in the frontal impact crash test and a Marginal overall rating in the side impact test.[8] 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/leg. Side airbags are limited to the curtain type for both front and rear rows, the torso type side airbag is unavailable.[9] 2007 models earned also only one out of five stars in a National Highway Traffic Safety Administration side-impact crash test.[10]

The CXS was replaced by the Super in the US market for 2008.[12] However, sales of the CXS continued in Canada until January 1, 2008.[13]

For the 2007 model year, Shanghai GM introduced the Buick LaCrosse as a more upscale companion to its Buick Regal sedan.[14] 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.


In 2008, Shanghai GM introduced a mild hybrid system on the LaCrosse. Using the Belt Alternator Starter system, it is the first hybrid vehicle in the Chinese market as well as the first hybrid in its segment.[15]







The Buick LaCrosse envelops you in luxury. Available premium leather-appointed seating, ice-blue ambient lighting, and the soft-touch instrument panel surround you to make your ride more comfortable and enjoyable.

Your passengers’ comfort isn’t left to chance either. In fact, our engineers designed first-class rear seating in this luxury sedan to have more rear legroom than even the Lexus ES 350, Acura TL, and Infiniti G37 sedans.



The design philosophy of the 2013 Buick LaCrosse can be summed up with one word: flowing. From end to end, this luxury sedan delivers a stunning body that is taut and sculpted. Everything from the striking waterfall grille and wraparound headlamps to side sweep spears flows seamlessly. Four available wheel options let you customize your look.



The optional push-button start ignites LaCrosse’s responsive performance. Inside, a 6-speed transmission with Driver Shift Control allows you to switch from automatic to clutchless manual operation. Engine choices and an advanced suspension system give you the tools to maximize your performance.



Optimize your driving experience by choosing either the 2.4L ECOTEC Direct Injection 4-cylinder engine with eAssist technology that offers an EPA-estimated fuel economy of 25 mpg city/36 mpg highway—or opt for the 280 horsepower V6 with EPA-estimated highway fuel economy of 27 mpg.


Drive with confidence with LaCrosse’s StabiliTrak and full-time traction control. This system monitors the road and steering input to help LaCrosse grip the road when you need it most.


When driving conditions demand more traction, LaCrosse’s intelligent All-Wheel Drive (AWD) constantly monitors traction at all four wheels. Whenever it detects slip, it automatically delivers power to the wheels with the best grip.


Our newest Buicks are designed to cater to your needs inside and out. Case in point: Buick IntelliLink,7 standard on the 2013 Buick LaCrosse. This high-definition color touch screen offers you a host of infotainment and navigation options, including intuitive voice command, Bluetooth®3 connectivity, smartphone integration, and Pandora® and Stitcher™ streaming Internet radio.

The 2013 Buick LaCrosse leads the way in passenger entertainment, with an available rear seat DVD system,5including dual screens that both feature an input jack for video games and other electronics.

The 2013 LaCrosse with eAssist is all about maximizing your fuel efficiency and your drive. Thanks to advanced technology, LaCrosse vehicles with eAssist offer an EPA-estimated fuel economy of 36 mpg highway,11 making them the most fuel-efficient sedan in their class. Because there’s nothing more exhilarating than a car that performs beautifully, yet sips gas.



When it comes to safety, this luxury sedan is fully committed to bringing the smartest thinking forward. See the road more clearly with available xenon High-Intensity Discharge (HID) articulating headlamps. Stay focused with the available Head-Up Display and Side Blind Zone Alert8. Drive more confidently with the available AWD. And breathe easier knowing you won’t find this combination of available collision avoidance technologies on Acura TL, Infiniti G37, or even Lexus ES 350. For more on the technologies Buick is innovating to help keep you safe, visit our Safety Page.



Highway driving has never been easier. The available system uses radar to watch where you can’t—in your blind zone. When a car enters your blind zone, it will display a signal in your outside mirror.

The 2013 LaCrosse was named a Top Safety Pick by the Insurance Institute for Highway Safety. The Institute rates vehicles based on high-speed front and side crash tests, a rollover test, and evaluations of seat/head restraints.
