Driver restraints and dummy kinematics Dummy movement was reasonably well controlled. During rebound, the dummy's head leaned partway out the open side window and hit the top and rear portions of the window frame.

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.

Action shot taken during rebound shows the dummy's head leaning partway out the open side window.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.
