Action shot taken during the frontal offset crash test.

The energy of the crash was absorbed by the front end of the car, preserving the driver's survival space very well.

Smeared greasepaint indicates where the dummy's head contacted the B-pillar, roof rail, grab handle, and head restraint during rebound. Head accelerations from these hits were low.

Forces on the lower right leg were high enough to indicate the possibility of injury.
