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 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 2023-24 models
Tested vehicle: 2023 Subaru Solterra Touring 4-door 4wd
The Subaru Solterra and Toyota bZ4X, both all-new electric vehicles, were introduced for the 2023 model year. Passenger-side small overlap frontal ratings are assigned by the Institute based on a test of a 2023 Solterra conducted by Subaru as part of frontal crash test verification.

How the passenger-side small overlap front test is conducted
Moderate overlap front: original test
Rating applies to 2023-24 models
Tested vehicle: 2023 Subaru Solterra Premium 4-door 4wd
The Subaru Solterra and Toyota bZ4X, both all-new electric vehicles, were introduced for the 2023 model year.

| Driver restraints and dummy kinematics |
Action shot taken during the moderate overlap frontal crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.
Smeared greasepaint indicates where the dummy's head contacted the side curtain airbag during rebound.
Forces on the right lower leg were just high enough to indicate the possibility of injuries.

Side: updated test
Rating applies to 2023-24 models built after October 2022
Tested vehicle: 2023 Subaru Solterra Touring 4-door 4wd
The Subaru Solterra and Toyota bZ4X, both all-new electric vehicles, were introduced for the 2023 model year. Beginning with 2023 models built after October 2022, reinforcements were implemented to improve occupant protection in side impact crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the driver door or adjacent B-pillar.)

| 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 good on the gradual left and both right curves and fair on the sharp left curve.
The low beams never exceeded glare limits.
High beams
On the straightaway, visibility was good 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.
