The Buick LaCrosse is a mid-size car produced by the Buick division of American automaker General Motors since 2004 as the 2005 model year. The LaCrosse, only available as a four-door sedan, replaces the Buick Century, Buick Regal and the Oldsmobile Intrigue after General Motors discontinued the brand. Its namesake is the Buick LaCrosse concept car shown beginning in 2000.
The original 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. However, la crosse means masturbation or swindling in Québecois slang, so it is sold as the Buick Allure in Canada.
