View of the vehicle after the crash showing the airbags and damage to the occupant compartment.

The rear passenger dummy's head came close to contacting the front seatback, which increases the risk of head injuries.

Rear passenger dummy injury values indicate a low risk of injury to the head or neck and chest. During the crash, the shoulder belt remained in an ideal position on the dummy’s chest.

The rear passenger dummy's lap belt remained in the ideal position on the pelvis.

Headlights

Ratings are given for 2 different headlight variations available on this vehicle.

(1) Trim level(s): eDrive35 trim equipped with Shadowline package, eDrive40 trim equipped with Shadowline package, xDrive40 trim equipped with Shadowline package, M50 trim

Evaluation criteria	Rating
Low-beam headlight type	LED projector
High-beam headlight type	LED projector
Curve-adaptive?	No
High-beam assist?	Yes
Overall rating
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 inadequate on both sides of the road. On curves, visibility was good on the gradual left curve and fair on the sharp left and both right curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the sharp left curve.

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 excessive glare.

High beams
On the straightaway, visibility was inadequate on both sides of the road. On curves, visibility was fair in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the gradual left curve.
