Tested vehicle: 2010 Buick LaCrosse CX 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
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). The car tested was a 2010 model without the option.
