View of the vehicle and barrier just after the crash test.
View of the vehicle after the crash with doors removed, showing the side airbags 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.
