2014 Toyota Sienna
minivan
Small overlap front: passenger-side
Rating applies to 2011-20 models
Tested vehicle: 2018 Toyota Sienna LE
The Toyota Sienna was redesigned for the 2011 model year. Although Toyota reinforced the structure in later model years on the driver side to improve occupant protection in small overlap frontal crashes, no such changes were made on the passenger side.

Action shot taken during the passenger-side small overlap frontal crash test.
The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger's survival space was not maintained well.
The frontal and side curtain airbags worked well together to keep the passenger dummy’s head from coming close to any stiff structure or outside objects that could cause injury.
Extensive intrusion of the dashboard and door hinge pillar contributed to a moderate risk of injuries to the right hip and right lower leg.

Side: original test
Rating applies to 2014-20 models
Tested vehicle: 2014 Toyota Sienna LE with standard head curtain airbags for all three rows of seats and standard front seat-mounted torso airbags
The Toyota Sienna was redesigned for the 2011 model year. Beginning with 2014 models, the side torso airbags were modified to improve the protection of drivers and front seat passengers in side impact crashes. Side ratings are assigned by the Institute based on tests conducted by Toyota.
Two tests of the Sienna were conducted, one of a 2011 model and the other representing a 2014 model. These vehicles are rated separately, except that the structure ratings for both vehicles are based on both tests, as are rear passenger dummy injury and head protection ratings, because no changes were made affecting structure or rear seat occupants. (The vehicle tested by Toyota was designated as a 2011 model but included the side torso airbag changes of the 2014 models.)
