|Restraints and dummy kinematics|
Important: Frontal crash test ratings should be compared only among vehicles of similar weight.
The Toyota Prius c was introduced in the 2012 model year and is derived from the Toyota Yaris.
The driver's space was seriously compromised by intruding structure. Lower interior intrusion measured as much as 30 cm at the lower hinge pillar. Upper interior intrusion measured as much as 20 cm at the hinge pillar and instrument panel. The steering column was pushed back 7 cm toward the driver.
Measures from the dummy indicate that injuries to the left lower leg would be likely in a crash of this severity. The risk of significant injuries to other body regions is low, including head injury risk from the instrument panel hit.
Restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved 12 cm to the right. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso, contributing to the head hitting the instrument panel. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects, and the driver's seat tipped forward and toward the B-pillar. The side torso airbag deployed.
