Injury measures

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

Restraints and dummy kinematics

Dummy movement was well controlled. After the dummy moved forward into the airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

Side crash test ratings can be compared across vehicle categories.

The BMW 3 series convertible was redesigned for the 2007 model year. Beginning with 2007 models built after April 2007, design changes were made to the side airbags to improve occupant protection in side impact crashes (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).

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures would be possible in a crash of this severity. In addition, loading to the shoulder was excessive.

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

Head protection

Driver — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side airbag that deployed from the seat.

Passenger — The dummy's head was hit by the interior side trim. This impact did not produce high head injury measures, but the head protection is inadequate.
