Small overlap front: driver-side

Rating applies to 2018-21 models

Tested vehicle: 2020 Chevrolet Traverse High Country 4-door 4wd

The Chevrolet Traverse and Buick Enclave were redesigned for the 2018 model year. They are smaller and lighter than the earlier design and therefore are now classified as midsize SUVs.

Action shot taken during the driver-side 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 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.

Despite some intrusion of the door hinge pillar, risk of injuries to the dummy's legs and feet was low.

Moderate overlap front

Rating applies to 2018-21 models

Tested vehicle: 2018 Chevrolet Traverse LT 4-door 4wd

The Chevrolet Traverse and Buick Enclave were redesigned for the 2018 model year. They are smaller and lighter than the earlier design and therefore are now classified as midsize SUVs. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by General Motors as part of frontal crash test verification.
