2014 Buick LaCrosse
large car / 4-door sedan
Moderate overlap front: original test
Tested vehicle: 2010 Buick LaCrosse CX 4-door
Rating applies to 2010-16 models
The Buick LaCrosse was redesigned for the 2010 model year. Frontal ratings are assigned by the Institute based on a test conducted by General Motors.

Side: original test
Tested vehicle: 2014 Buick LaCrosse 4-door with standard front and rear head curtain airbags and standard front and rear seat-mounted torso airbags
Rating applies to 2014-16 models
The Buick LaCrosse was redesigned for the 2010 model year. Beginning with 2014 models, side torso airbags became standard for rear seat occupants (they were optional in 2010-13 models). Also, the front door trim was modified.
Two tests of the LaCrosse were conducted, one of a 2010 model (without the then-optional rear side torso airbags) by the Institute and the other a 2014 model by General Motors. These vehicles are rated separately, except that the structure ratings for both vehicles are based on both tests.
