Restraints and dummy kinematics
The dummy’s head remained in contact with the frontal airbag, but the head was still vulnerable to contact with forward side structure because the steering column moved 13 cm to the right as the dummy moved to the left. The driver's seat tipped forward and toward the B-pillar. Furthermore, at forwardmost excursion the head had moved outside the open side window, partially due to the lack of a side curtain airbag deployment and leaving the head vulnerable to 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 wasn't maintained well.

Intrusion into the occupant compartment was extensive. The dummy's left foot was trapped by intruding structure as the left front wheel was forced rearward during the crash. The right foot was trapped beneath the brake pedal.

Although the dummy's head remained engaged with the frontal airbag during the crash, it became vulnerable to hard contacts because the steering column moved too far to the right and the head moved outside the open side window.

Restraints and dummy kinematics

Action shot taken during the frontal offset 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 hit the A-pillar, sun visor, and roof rail during rebound. Head accelerations from these hits were low.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.
