2017 Toyota Prius c
minicar / 4-door hatchback
Small overlap front: driver-side
Rating applies to 2015-19 models built after May 2015
Tested vehicle: 2015 Toyota Prius c Two 4-door
The Toyota Prius c was introduced in the 2012 model year and is derived from the Toyota Yaris. Beginning with 2015 Prius c models built after May 2015, the front-end and occupant compartment structure was modified and the side curtain airbags were lengthened to improve occupant protection in 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.)

Driver restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso, contributing to the head hitting the instrument panel, and the driver's seat tipped forward and toward the B-pillar. 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. |
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 reasonably well.
During the crash, the dummy's head barely contacted the airbag before sliding off to the left. The seat belt allowed the dummy to move too far forward, and the head hit the instrument panel.
Intrusion of the door hinge pillar and instrument panel contributed to a moderate risk of injury to the left lower leg.
