Small overlap front: driver-side

Rating applies to 2020-24 models

Tested vehicle: 2020 Subaru Legacy 2.5i Premium 4-door 4wd

The Subaru Legacy was redesigned for the 2020 model year. Driver-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Subaru as part of frontal crash test verification.

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 2020.

How the driver-side small overlap front test is conducted

Small overlap front: passenger-side

Rating applies to 2020-24 models

Tested vehicle: 2020 Subaru Legacy 2.5i Premium 4-door 4wd

The Subaru Legacy was redesigned for the 2020 model year. Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Subaru as part of frontal crash test verification.

The passenger-side small overlap frontal crash test ratings also apply to the station wagon version of the Legacy, known as the Outback, also redesigned for 2020.

Passenger restraints and dummy kinematics
The dummy’s head contacted the right side of the frontal airbag but began to move into the gap between the frontal and side curtain airbags, leaving the head vulnerable to contact with forward structure. The inflated side curtain airbag has sufficient forward coverage to protect the head from contact with side structure and outside objects.

Low beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was good on both right curves and fair on both left curves.

The low beams created some glare.

High beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was good on the gradual left and both right curves and fair on the sharp left curve.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and on both left curves.

Low beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was fair on the sharp left and both right curves and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was inadequate in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on the gradual right curve.
