Two tests of a 2010 Mustang convertible were conducted. In the first test, forces recorded on the dummy's neck were high, leading to a poor head/neck injury rating and a poor overall rating. In response, Ford modified the convertible's front structure and the doors to improve occupant protection in frontal offset crashes beginning with cars manufactured after December 2009 (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

In the second test of a car built after the structural modifications were in place, the head/neck and overall ratings improved to good.

Injury Measures:
Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints / Dummy Kinematics:
Dummy movement was well controlled. The driver side airbag deployed during the crash. After the dummy moved forward into the frontal airbag, its head contacted the side airbag.

Driver Injury Measures:
Measures taken from the dummy indicate that rib fractures would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Passenger Injury Measures:
Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.
