Small overlap front: driver-side

Rating applies to 2017-23 models

Tested vehicle: 2017 GMC Acadia SLT1 4-door 4wd

The GMC Acadia was redesigned for the 2017 model year. It is smaller and lighter than the earlier design and therefore is now classified as a midsize SUV.

The earlier design remained in production for only the 2017 model year, available new only to fleet buyers, and was called the GMC Acadia Limited. The ratings on this page do not apply to the Acadia Limited.

These ratings also apply to the Cadillac XT6, a midsize luxury SUV introduced in the 2020 model year.

Driver restraints and dummy kinematics

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 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.

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2020-21 models

Tested vehicle: 2021 GMC Acadia SLE 4-door 4wd

The GMC Acadia was redesigned for the 2017 model year. It is smaller and lighter than the earlier design and therefore is now classified as a midsize SUV. Beginning with 2020 models, a new passenger-side airbag was implemented to improve occupant protection in passenger-side small overlap crashes.

The earlier design remained in production for only the 2017 model year, available new only to fleet buyers, and was called the GMC Acadia Limited. The ratings on this page do not apply to the Acadia Limited.

Action shot taken during the passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger'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 passenger’s space was maintained well, and risk of injuries to the dummy's legs and feet was low.

About the small overlap front test

Moderate overlap front: original test

Rating applies to 2017-23 models

Tested vehicle: 2017 GMC Acadia All Terrain 4-door 4wd

The GMC Acadia was redesigned for the 2017 model year. It is smaller and lighter than the earlier design and therefore is now classified as a midsize SUV.

The earlier design remained in production for only the 2017 model year, available new only to fleet buyers, and was called the GMC Acadia Limited. The ratings on this page do not apply to the Acadia Limited.

Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by General Motors on an Acadia. These ratings also apply to the Cadillac XT6, a midsize luxury SUV introduced in the 2020 model year.

Low beams
On the straightaway, visibility was fair on both sides of the road. On curves, visibility was fair on the sharp right curve and inadequate on the gradual right and both left curves.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was inadequate in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
