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.

Distance at which headlights provide at least 5 lux illumination:

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

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