Small overlap front: driver-side

Rating applies to 2019-20 models

Tested vehicle: 2019 Subaru Ascent Premium 4-door 4wd

The Subaru Ascent was introduced in the 2019 model year.

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.

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 very well.

Smeared greasepaint indicates where the dummy's head contacted the side curtain airbag during forward movement and rebound.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were 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 the gradual left and both right curves and fair on the sharp left curve.

The low beams created some glare.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.

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