Moderate overlap front: original test
Rating applies to 2005-06 models
Tested vehicle: 2002 Subaru Impreza 2.5 RS 4-door
The Subaru Impreza was redesigned for the 2002 model year. Imprezas manufactured after September 2001 include structural changes to improve occupant protection in frontal crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). The Saab 9-2X was introduced in the 2005 model year and discontinued after the 2006 model year.
The Insurance Institute for Highway Safety has evaluated the crashworthiness of an Impreza with the structural changes in a 40 mph frontal offset crash test into a deformable barrier.
The frontal offset crash test ratings also apply to the station wagon version of the Impreza, beginning with 2002 models manufactured after September 2001. The 9-2X was available only as a wagon.

Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates the driver's survival space was maintained well.
Smeared greasepaint indicates where the dummy's head brushed the B-pillar during rebound. Head acceleration from this hit was negligible.
There was little change in the position of the dummy's feet following the crash test. Injury risk was low.

Rating applies to 2006 models
Tested vehicle: 2006 Subaru Impreza 2.5i 4-door with standard front seat-mounted combination head and torso airbags
The Subaru Impreza was redesigned for the 2002 model year. Side airbags designed to protect drivers' and front passengers' heads and torsos became standard beginning with 2006 models (optional in 2004-05 models). The Saab 9-2X was introduced in the 2005 model year, equipped with standard side airbags using the same design as in the Impreza. The 9-2X was discontinued after the 2006 model year.
Beginning with 2006 Impreza and 9-2X models, a reinforcement was added to the the pillar behind each rear passenger door to improve occupant protection in side impact crashes.
The side impact crash test ratings also apply to the station wagon version of the Impreza, beginning with 2006 models. The 9-2X was available only as a wagon.
