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 and head restraint during rebound. Head accelerations from these hits were low.
There was little change in the position of the dummy's feet following the crash test. Footwell intrusion was minimal, and injury risk was low.

Tested vehicle: 2005 Mercedes-Benz C 240 4-door with standard front and rear head curtain airbags and standard front and rear door-mounted torso airbags
The Mercedes C class was redesigned for the 2001 model year. Modifications were made to the front seats and side airbags beginning with 2005 models to improve occupant protection in side-impact crashes. Beginning with 2006 models, the side airbags designed to protect rear passengers' torsos became optional (standard in 2005 models).

View of the vehicle and barrier just after the crash test.
View of the vehicle after the crash with doors removed, showing the side curtain airbag and damage to the occupant compartment.
Action shot taken during the side impact crash test showing the driver dummy's head was protected from being hit by hard structures by the side airbags.
Smeared greasepaint shows where the rear passenger dummy's head was protected by the side curtain airbag. Also shown is the door-mounted torso airbag, standard on the tested 2005 model, but optional beginning in 2006.
