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

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.

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

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