| 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 side structure. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag deployed. |
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 not maintained well.
During the crash, the dummy's head and torso barely contacted the airbag before sliding off to the left. The side curtain airbag did not extend far enough forward toward the A-pillar.
Despite considerable intrusion of the door hinge pillar and instrument panel, risk of injuries to the dummy's legs and feet was low.
