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 very well.
Smeared greasepaint indicates where the dummy’s head hit the B-pillar, roof rail, grab handle, and head restraint. Head accelerations from these hits were low.
Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.
