Small overlap front: driver-side

Rating applies to 2016-20 models

Tested vehicle: 2016 Buick Envision Premium I 4-door 4wd

The Buick Envision was introduced in the 2016 model year.

Driver restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side, leaving the head vulnerable to contact with forward structure. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso to the extent the head hit the steering wheel rim. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects.

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 well.

During the crash, the dummy's head barely contacted the frontal airbag before sliding off to the left as the steering column moved to the right, and the seat belt allowed far too much forward movement of the dummy.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Action shot taken during the moderate overlap frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.

Smeared greasepaint indicates where the dummy's head contacted the frontal and side curtain airbags during forward movement.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

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

The low beams created some glare.

High beams
On the straightaway, visibility was inadequate on both sides of the road. 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 and on the gradual left curve.
