Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Toyota Sienna was redesigned for the 2011 model year. Beginning with 2015 models, the front end structure was modified to improve occupant protection in small overlap frontal crashes.

Structure

The driver space was not maintained well, with maximum intrusion of the upper interior of 13-14 cm at the upper hinge pillar and instrument panel. Lower interior intrusion measured 12 cm at the parking brake pedal and 11 cm at the hinge pillar.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

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. The side torso airbag also deployed.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Toyota Sienna was redesigned for the 2011 model year. Frontal ratings are assigned by the Institute based on a test conducted by Toyota as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. The side curtain airbags on both sides of the vehicle deployed during the crash. After the dummy moved forward into the frontal airbag, its head contacted the driver side curtain airbag.

Side crash test ratings can be compared across vehicle categories.

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 as part of side crash test verification.

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.)

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
