Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Chevrolet Impala was redesigned for the 2014 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by General Motors as part of frontal crash test verification.

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 lower leg injuries would be possible.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain airbag deployed during the crash. After the dummy moved forward into the frontal airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

Side crash test ratings can be compared across vehicle categories.

The Chevrolet Impala was redesigned for the 2014 model year. Side ratings are assigned by the Institute based on a test conducted by General Motors as part of side crash test verification.

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof and a side airbag that deployed from the seat.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
