Small overlap front: driver-side

Rating applies to 2017-23 models

Tested vehicle: 2017 Subaru Impreza 2.0i 4-door 4wd

The Subaru Impreza was redesigned for the 2017 model year and the Subaru Crosstrek was redesigned for the 2018 model year. Two driver-side small overlap frontal tests of the Impreza were conducted, one by the Institute and the other by Subaru. Ratings are based on both tests and apply to both the 4-door sedan and wagon versions of the Impreza as well as 2018 and later models of the Crosstrek wagon.

The Subaru Crosstrek Hybrid, a plug-in hybrid electric variant of the Crosstrek wagon, was introduced in the 2019 model year. Ratings also apply to the Crosstrek Hybrid.

Action shot taken during the Institute's 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 very well (Institute test car shown).

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 (Institute test shown).

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

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2017-23 models

Tested vehicle: 2017 Subaru Impreza 2.0i Premium wagon 4wd

The Subaru Impreza was redesigned for the 2017 model year and the Subaru Crosstrek was redesigned for the 2018 model year. Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Subaru. Ratings apply to both the 4-door sedan and wagon versions of the Impreza as well as 2018 and later models of the Crosstrek wagon.

The Subaru Crosstrek Hybrid, a plug-in hybrid electric variant of the Crosstrek wagon, was introduced in the 2019 model year. Ratings also apply to the Crosstrek Hybrid.
