Arriving as a 2010 model, the new Buick Lacrosse is built upon the mid-size Epsilon II platform, which is also the basis for the Opel Insignia and the 2010 Saab 9-5. The design was based on 2008 Buick Invicta concept, and replaces both the Chinese and North American models. Buick states that the new LaCrosse will be "America's Lexus fighter". With the new 2011 Regal and the coming demise of Lucerne, the LaCrosse is no longer seen as Buick's entry-level model, but as its premium sports sedan. All models are equipped with the Hydra-Matic 6T70 6-speed automatic transmission. The LaCrosse was unveiled at the 2009 North American International Auto Show in Detroit, Michigan. The Chinese version was shown at Auto Shanghai in April 2009. The car was also shown at the 2009 Montreal International Auto Show as the Buick Allure. The LaCrosse will be sold in Mexico starting in 2010, as the Buick brand returns to the country after 13 years of absence. The GM Daewoo Alpheon was introduced at the 2010 Busan International Motor Show on Thursday, April 29 and is essentially a rebadged Buick LaCrosse.Second generation (2010–present)
