This rating applies to vehicles other than the specific model and body style tested.
The Pontiac Trans Sport (renamed Montana in 1999), the Chevrolet Venture, and the Oldsmobile Silhouette were redesigned for the 1997 model year. The Silhouette was dropped after the 2004 model year, and a limited number of Pontiac Montanas and Chevrolet Ventures were manufactured for the 2005 model year.
Injury measures
Measures taken from the chest indicate low risk of injuries to this body region in a crash of this severity. Forces on the neck indicate that injuries to the neck would be likely. Forces on both tibias indicate that injuries to the lower legs would be likely. The forces on the left lower leg were so high that the dummy's metal foot broke off from its leg at the ankle.
Restraints and dummy kinematics
Dummy movement wasn't well controlled. After moving forward into the airbag, the dummy's head and neck were snapped rearward as the steering wheel intruded. Then the dummy's head was hit from behind by the seatback and head restraint as they tilted forward because of floor buckling. The seat continued moving forward and pushed down on top of the dummy's head, bending its neck back even farther.
