The Buick LaCrosse is classified as a full-size sedan produced by American carmaker General Motors. Production of this vehicle started in 2004 and it effectively replaced both the Century and Regal in the North American market starting with the 2005 model year. This car became a top level sedan in North America at the beginning of its second generation and replaced the Buick Lucerne. The LaCrosse was first introduced in 2004 and a revised version of the W-body, also known as the MS2000, was used.
This vehicle initially came with two different powerplant options in three trim levels, including the 3.8 liter 3800 Series III V6, available as the base CX and mid-level CXL trims, and the 3.6 liter HFV6 as the higher end CXS model. This vehicle’s power is routed to the front wheels by a 4T65-E automatic transmission. The name for the LaCrosse comes from a Buick concept car of the same name that was first displayed in 2000. This sedan was first sold as the Buick Allure in Canada, where it was at one time Buick’s top-selling vehicle until 2008.
The LaCrosse, as well as all other GM vehicles, is powered by a 3.8 liter V6, becoming the very first SULEV-compliant vehicle for 2006. The 2008 model LaCrosse received quite a few updates, starting with its front end design, which was based on the Buick Velite concept. There were also some new body color choices made available for this vehicle, including Scarlett Red, Gold Mist Metallic, Dark Mocha Metallic, and Dark Slate Metallic. All of the trim levels that were initially offered for this vehicle gained a chrome exterior appearance package, including XM Satellite Radio, factory remote start, telescoping steering column, redundant steering wheel controls, and dual-zone climate control as a standard feature. The CX trim level for this vehicle came with a leather-wrapped steering wheel as well as a theft deterrent system and illuminated vanity mirrors.
The second generation LaCrosse was built on the mid-size Epsilon II platform in its long wheelbase version. The design for this vehicle based also based on the Buick Invicta concept car from 2008, and it effectively replaced the Chinese and North American models. Buick has stated that the new LaCrosse will easily be able to go up against some of Lexus’s current models with its innovative and unique design as well as a variety of features.
Buick’s VentiPorts and Sweepspear made a reappearance with the second generation model, a styling feature that is unique to Buick and dates all the way back to the late 1940s. The second generation of this vehicle was first displayed to the public in 2009 at the North American International Auto Show in Detroit, Michigan. This car was also displayed at the Montreal International Auto Show as the Buick Allure in 2009. Production of all the North American models of this vehicle was moved from Oshawa to the Fairfax Assembly plant, located in Kansas City, Kansas.
A 2.4 liter Ecotec 4-cylinder engine was used for the second generation LaCrosse, replacing the 3.0 V6 as the standard engine on the CX model. The old 3.6 liter V6 is still an option on the CX as well as front-wheel drive on the CXL, and it is a standard feature on the CXS trim level. A HiPer Strut front suspension design was used for this vehicle, which was a substantial departure from anything that had been seen in Buick’s vehicles in the past. A mild hybrid version of the LaCrosse came out in 2012, called the eAssist. This vehicle introduced GM’s second generation Belt-Alternator-Start system and was released to very positive reviews from critics.
