The second generation of the Buick LaCrosse was introduced in 2009 at the North American International Auto Show in Detroit as a 2010 model.
It was more of a revolution than just an evolution of its predecessor. GM used the Epsilon II LWB platform for it, shared with other cars from the group such as the Opel/Vauxhall Insignia, Buick Regal, or Chevrolet Impala. GM completed the new design language with a new engine lineup that provided either more powerful or more fuel-efficient powerplants.

The angled, swept-back headlights with tight corners formed an aggressive look for the big Buick sedan at the front. The waterfall grille was already a common aesthetic concept for the American premium brand. On its sides, the sculptured beltline resembled some older vehicles from Buick’s lineup. In the back, the enlarged taillights cut a big chunk of the rear quarter-panels.

Inside, Buick emphasized the accent on technology and introduced a new infotainment system with an option for DVD-player for the rear seat passengers was available on the options list. Theaters seats inspired the elegant cabin with wide seats at the front and curved center console. GM enhanced the safety in the LaCrosse. Its adaptive headlights, which ensured 15 degrees illumination on curves, introduced more airbags for side protection.

Under the hood, GM installed a wide choice of gasoline engines paired exclusively to a 6-speed automatic gearbox. Power went to the front or in all corners for selected versions.
