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.

This vehicle has 2 rear seating positions with complete child seat attachment (LATCH) hardware. It has 1 additional seating position with a tether anchor, a single lower anchor and the ability to borrow the second anchor from another position. Note: When anchors are borrowed, they aren't available to use in their designated positions.
