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.

Loading of the head into the airbag is shown in this photo taken during the crash test.

Smeared greasepaint indicates where the dummy's left knee and shin hit the instrument panel and knee bolster. Intrusion into the driver's space was minimal.
