2018 Subaru Legacy
midsize car / 4-door sedan
Award applies only to vehicles with optional front crash prevention and specific headlights
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.

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.

Small overlap front: passenger-side
Rating applies to 2018-19 models
Tested vehicle: 2018 Subaru Outback 2.5i wagon 4wd
The Subaru Outback was redesigned for the 2015 model year. Beginning with the 2018 model year, the front-end and occupant compartment structure was reinforced to improve occupant protection in passenger-side small overlap crash tests. The small overlap frontal crash test ratings also apply to the sedan version of the Outback, known as the Legacy, also redesigned for 2015 and similarly modified in 2018.

Action shot taken during the passenger-side small overlap frontal crash test.
The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger’s survival space was maintained very well.
The frontal and side curtain airbags worked well together to keep the passenger dummy’s head from coming close to any stiff structure or outside objects that could cause injury.
The passenger’s space was maintained well, and risk of injuries to the dummy's legs and feet was low.

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, fair on the sharp left curve and inadequate on the gradual left curve.
The low beams never exceeded glare limits.
High beams
On the straightaway, visibility was fair on both sides of the road. On curves, visibility was good on both right curves and fair on both left curves.
High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on the sharp right curve.
