Driver restraints and dummy kinematics

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 pink and red greasepaint indicates where the dummy's head hit the roof rail during rebound. Head acceleration from this hit was low.

Forces on the lower right leg were high enough to indicate the possibility of injury.

How the moderate overlap front test is conducted

Side

Rating applies to 2008-10 models built after May 2007

Tested vehicle: 2008 BMW 528i 4-door with standard front and rear head tubular airbags and standard front door-mounted torso airbags

The BMW 5 series was redesigned for the 2004 model year. Beginning with 2008 models built after May 2007, modifications were made to the side tubular head protection 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). Door trim changes were also made beginning with 2008 model year production. The tested car was manufactured after the modifications had been made.

View of the vehicle after the crash with doors removed, showing the side tubular airbag and damage to the occupant compartment.

Smeared greasepaint shows where the driver dummy's head was protected from being hit by hard structures by the side airbags.

Smeared red greasepaint shows where the rear passenger dummy’s head was protected by the side airbag.
