Small overlap front: driver-side
Rating applies to 2020-24 models
Tested vehicle: 2021 Buick Encore GX Select 4-door 4wd
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.

Action shot taken during the small overlap frontal crash test.
The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.
The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.
The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.
