The Buick LaCrosse is a mid-size luxury sedan produced by General Motors. The Buick LaCrosse, is a four-door sedan which replaced the Buick Century and Regal in North America beginning in the 2005 model year.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 Super's).
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') in Quebec French slang.[3] It was once Buick's best-selling vehicle in Canada until 2008, when the Enclave became the brand's best-seller, of 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, 2008.2008
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.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.
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, 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 GXP, Impala 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.
