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 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.

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).
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.
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).
