The Buick Lacrosse, a mid-size sedan produced by General Motors from 2005 to 2009, marked a significant departure from its predecessors. The 2005-2008 models, in particular, showcased Buick's attempt to reimagine its brand identity, moving away from the traditional luxury image associated with its earlier sedans towards a more contemporary and sporty aesthetic. The Lacrosse's sleek design, featuring sharp lines and a bold front grille, aimed to attract a younger audience seeking a sophisticated yet stylish driving experience. Inside, the cabin was designed with an emphasis on comfort and technology, boasting features such as a premium sound system, leather seating, and a well-equipped dashboard.

Under the hood, the Lacrosse offered a choice of two V6 engines: a 3.8L V6 producing 200 horsepower for the base model, and a 3.6L V6 generating 240 horsepower for the higher-end trim levels. The 2005-2008 Lacrosse also introduced a new, more refined driving experience thanks to its independent rear suspension, providing both comfort and handling capabilities. However, despite the improvements, the first generation Lacrosse received mixed reviews from critics, with some praising its sleek design and comfortable interior while others criticized its handling and fuel economy. Nevertheless, the model paved the way for Buick's subsequent success in the mid-size sedan segment with the release of the second-generation Lacrosse in 2010, which was better received and helped revive the brand's image.
