Small overlap front: driver-side

Rating applies to 2014-15 models built after November 2013

Tested vehicle: 2014 Toyota Prius Two 4-door

The Toyota Prius was redesigned for the 2010 model year. As in earlier models, the Prius is a hybrid with both a gasoline engine and electric motor. A Prius Plug-in model was introduced in the 2012 model year. This variant also uses a gasoline engine and electric motor, but the motor's lithium-ion battery can be charged by connecting it with an electrical cord to a standard household outlet. The Plug-in is designed to operate primarily in electric mode for 11 miles from a full charge. Beyond this range, it operates in the same manner as the standard Prius.

Beginning with 2014 Prius and Prius Plug-in models, the front structure was modified and the side curtain airbags were lengthened to improve occupant protection in small overlap frontal crashes. Then, starting with 2014 cars built after November 2013, the 15-inch alloy wheels standard on most models were sourced from a single supplier to provide a more controlled crush during the small overlap test. (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.)

Restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side, leaving the head vulnerable to contact with forward structure. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects.

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 not maintained well.

During the crash, the dummy's head barely contacted the frontal airbag before sliding off to the left, and the seat belt allowed the dummy to move too far forward, as is evident from the gap between the dummy's torso and the seat back.

Despite considerable intrusion of the door hinge pillar, parking brake pedal (see arrow), and instrument panel, risk of injuries to the dummy's legs and feet was low.

Tested vehicle: 2010 Toyota Prius 4-door

The Toyota Prius was redesigned for the 2010 model year. As in earlier models, the Prius is a hybrid with both a gasoline engine and electric motor. A Prius Plug-in model was introduced in the 2012 model year. This variant also uses a gasoline engine and electric motor, but the motor's lithium-ion battery can be charged by connecting it with an electrical cord to a standard household outlet. The Plug-in is designed to operate primarily in electric mode for 11 miles from a full charge. Beyond this range, it operates in the same manner as the standard Prius.

Two tests of the Prius were conducted, the first by Toyota of a 2010 Prius as part of frontal crash test verification and the second by the Institute of a 2012 Prius Plug-in. Ratings are based on both tests and apply to both Prius variants. Vehicle specifications are provided for the 2010 Prius from the Toyota test and photos are provided from the Institute's test of the 2012 Prius Plug-in.

Restraints and dummy kinematics

Action shot taken during the Institute's moderate offset 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 (Institute test car shown).

In both tests, intrusion into the driver's space was minimal, and all leg and foot injury measures were low (the yellow strip is marking tape that came off the instrument panel during the Institute's test).

Dummy movement was well controlled in both tests. During rebound in the Institute's test, the dummy's head hit the roof rail, as indicated by smeared greasepaint.
