Small overlap front: driver-side

Rating applies to 2015-21 models

Tested vehicle: 2015 Subaru WRX Premium 4-door 4wd

The Subaru WRX was redesigned for the 2015 model year. Although the car shares some of its design elements with the Subaru Impreza, there are now sufficient differences for the WRX to be rated separately.

Driver restraints and dummy kinematics

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Driver restraints and dummy kinematics

Action shot taken during the moderate overlap frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

Small greasepaint marks on the side curtain airbag show that the dummy's head motion was well controlled as it moved forward into the frontal airbag and then back toward the seat during the crash.

Forces on the lower left leg were high enough to indicate the possibility of injuries.

About the original moderate overlap front test

Tested vehicle: 2017 Subaru WRX Premium 4-door 4wd

The Subaru WRX was redesigned for the 2015 model year. Although the car shares some of its design elements with the Subaru Impreza, there are now sufficient differences for the WRX to be rated separately. Beginning with 2017 models, the side curtain and side thorax airbags were modified to improve occupant protection in side impact crashes.

Two tests of the WRX were conducted, one of a 2015 model by the Institute and the other of a 2017 model by Subaru. These vehicles are rated separately, except that the structure ratings for both vehicles are based on both tests.
