Small overlap front: driver-side
Tested vehicle: 2021 Buick Encore GX Select 4-door 4wd
Rating applies to 2020-25 models
The Buick Encore GX was introduced in the 2020 model year as a replacement for the Buick Encore, while the 2021 Chevrolet Trailblazer returns after an 11-year absence from the market as a replacement for the Chevrolet Trax. Two small overlap frontal tests of the Encore GX were conducted, one by the Institute and the other by General Motors . Ratings are based on both tests, but the vehicle specifications shown below are based on the Institute’s test.
