Small overlap front: driver-side

Rating applies to 2016-19 models

Tested vehicle: 2016 Toyota Prius Two Eco 4-door

The Toyota Prius was redesigned for the 2016 model year and the Prius Prime was introduced in the 2017 model year.

Action shot taken during the 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.

How the driver-side small overlap front test is conducted

Small overlap front: passenger-side

Rating applies to 2018-19 models built after May 2018

Tested vehicle: 2018 Toyota Prius Two 4-door

The Toyota Prius was redesigned for the 2016 model year and the Prius Prime was introduced in the 2017 model year. Beginning with 2018 models of the Prius and Prius Prime built after May 2018, a structural brace was added to the passenger-side lower door hinge pillar to improve occupant protection in passenger-side small overlap frontal crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Passenger-side small overlap frontal ratings are assigned by the Institute based on a test conducted by Toyota as part of frontal crash test verification.

Passenger restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the right side, allowing the head to move far enough forward to hit the dashboard. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Low beams
On the straightaway, visibility was good on the right side of the road and inadequate 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 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.
