The Fiat 500 was introduced in the 2012 model year. Two tests of a 2012 Fiat 500 were conducted. In the first test, forces recorded on the dummy's head were high when it hit the steering wheel through the airbag, indicating that head injuries would be possible. Postcrash investigation revealed that a steel cross tube in the seat structure was pulled out at one end and contributed to the seat pitching forward during the crash and the dummy's head moving too far forward into the airbag. In response, Fiat Chrysler modified the seat structure to improve occupant protection in frontal crashes beginning with cars manufactured after July 2011. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)
In the second test of a car built after the seat modifications were in place, forces on the dummy's head were reduced, but the driver door unlatched. Because the front end structure of the car was not affected by the seat modifications or the door opening, structure ratings are based on both tests.
Postcrash investigation indicates that the door opening occurred because the dummy's arm broke the interior door handle, and the access hole for a bolt at the dummy's elbow engaged and activated the door latch. The door opening in the second test is an artifact of the dummy arm construction. Therefore, it is unlikely that in an actual crash the door latch would be activated.
Measures taken from the neck and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the head when the dummy hit the steering wheel through the frontal airbag indicate that head injuries would be possible. Forces on the right foot indicate that foot injuries would also be possible.
Restraints and dummy kinematics
Dummy movement appeared to be well controlled even though the driver door opened. The driver side curtain and side torso airbags deployed during the crash. During rebound, the dummy's head contacted the side curtain airbag.
