2014 Toyota Prius
small car / 4-door hatchback
Award applies only to vehicles with optional front crash prevention built after November 2013
Small overlap front: driver-side
Tested vehicle: 2014 Toyota Prius Two 4-door
Rating applies to 2014-15 models built after November 2013
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.)

| Driver 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. |

Two tests of the Prius were conducted, the first by Toyota of a 2010 Prius 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.
