Small overlap front: driver-side
Tested vehicle: 2015 Buick Encore Convenience Group 4-door 4wd
Rating applies to 2015-22 models
The Buick Encore was introduced in the 2013 model year and the Chevrolet Trax was introduced in the 2015 model year. Beginning with 2015 models of the Encore and Trax, the front-end structure was modified to improve occupant protection in small overlap frontal crashes.
