The Chevrolet Impala was reintroduced for the 2000 model year as a somewhat smaller front-wheel-drive sedan.
Injury measures
Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the right tibia indicate that injury to the lower leg would be possible. Acceleration on the left foot indicates that injuries to the foot would be possible.
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.
