Small overlap front: driver-side

Rating applies to 2020-25 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.

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 2020-25 models built after October 2019

Tested vehicle: 2020 Cadillac XT6 Platinum Premium Luxury 4-door 4wd

The Cadillac XT6 was introduced in the 2020 model year. This midsize luxury SUV is built on the same platform as the GMC Acadia. Beginning with 2020 models built after August 2019, the passenger-side front door hinge pillar and A-pillar were reinforced to improve occupant protection in passenger-side small overlap frontal crashes. Beginning with 2020 models built after October 2019, changes to the side curtain airbags were implemented to further improve occupant protection.

Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by General Motors.

Distance at which headlights provide at least 5 lux illumination:

Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.

The low beams created some glare.

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 good in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on the gradual right curve.
