Small overlap front: driver-side

Rating applies to 2015-19 models

Tested vehicle: 2015 Subaru Legacy 2.5i 4-door 4wd

The Subaru Legacy was redesigned for the 2015 model year. The driver-side small overlap frontal crash test ratings also apply to the station wagon version of the Legacy, known as the Outback, also redesigned for 2015.

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 very 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.

How the driver-side small overlap front test is conducted

Moderate overlap front: original test

Rating applies to 2015-19 models

Tested vehicle: 2015 Subaru Legacy 2.5i Premium 4-door 4wd

The Subaru Legacy was redesigned for the 2015 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Subaru as part of frontal crash test verification.

The moderate overlap frontal crash test ratings also apply to the station wagon version of the Legacy, known as the Outback, also redesigned for 2015.
