2014 Toyota Sienna

Tested vehicle: 2018 Toyota Sienna LE
Rating applies to 2011-20 models

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.

About the original moderate overlap front test

Tested vehicle: 2014 Toyota Sienna LE with standard head curtain airbags for all three rows of seats and standard front seat-mounted torso airbags
Rating applies to 2014-20 models

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.)
