Restraints and dummy kinematics

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 reasonably 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.

Footrest, parking brake, and instrument panel intrusion contributed to a significant risk of injury to the left lower leg.

Moderate overlap front

Rating applies to 2014-15 models

The low beams never exceeded glare limits.

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

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