STORY

The LaCrosse was Buick's mid-to-full-size sedan from 2005 to 2019, replacing the Century and Regal. Early cars used GM's W-body, while later generations moved to newer GM platforms with V6 and eAssist mild-hybrid powertrains, growing more luxurious and technologically advanced. It was among the last Buick sedans sold in North America before the brand shifted entirely to crossovers and SUVs.
