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

The Subaru Impreza was redesigned for the 2008 model year. Frontal ratings are assigned by the Institute based on a test conducted by Subaru as part of frontal crash test verification. The frontal ratings also apply to the 4-door sedan version of the Impreza.

Injury measures

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

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.

Side crash test ratings can be compared across vehicle categories.

The Subaru Impreza was redesigned for the 2008 model year. The side impact crash test ratings also apply to the 5-door (wagon) version of the Impreza.

Injury measures

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

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.

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.
