From the outside, the 2012 Buick LaCrosse looks like a big, roomy sedan, and inside the cabin it's fully in accord with that impression. The LaCrosse has room for five, as well as one of the few back seats where (thanks to a little added width) you can fit three across. And its relatively tall, not-too-swoopy roofline and front-wheel-drive layout bolster the impression of space. Trunk space is vast as well.
Front seats in the LaCrosse are nothing to grumble about—they're a bit soft but long-distance comfortable nevertheless. A wide range of materials, including plastic, wood and leather, with quality rising as you move up the model line—although the faux wood in some models feels a little out of place.
The interior in top models feels lavish, with nice detailing and trim, as well as ambient lighting, and rivals Lexus interiors, but base models especially can feel just a little bit simple and plasticky. The faux stitching on the dashboard and well-upholstered and bolstered seats make for a more luxurious setting than might be expected from the LaCrosse's mid-market pricing, and the top-level CXS gets upgraded perforated leather and ventilated heating and cooling features, along with more adjustability and memory settings.
The LaCrosse has a ride that's smooth but not floaty, and in keeping with Buick's 'Quiet Tuning' philosophy, nearly all the wind and road noise are nicely damped out. But we have noticed that models with the larger 19-inch wheels have some noticeable road noise.
Our one criticism of the LaCrosse with the 3.6-liter V-6 is that it's a little raspy-sounding in this application—more vocal than the four, it seems—and its character doesn't marry so well with the otherwise sophisticated and supremely muted and isolated character.
