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

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

How the moderate overlap front test is conducted

Side: original test

Rating applies to 2007-10 models

Tested vehicle: 2007 Jeep Grand Cherokee Laredo 4-door 4wd with standard front and rear head curtain airbags

The Jeep Grand Cherokee was redesigned for the 2005 model year. Beginning with 2007 models, side airbags were made standard (they were optional in 2005-06 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 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 curtain airbag.

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