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.
During rebound, the dummy's head hit only the head restraint.
Although intrusion into the footwell area was minimal, left foot acceleration was high, indicating the possibility of injury.
