Moderate overlap front: original test

Rating applies to 2004-10 models

Tested vehicle: 2004 Toyota Sienna LE

The Toyota Sienna was redesigned for the 2004 model year.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the Sienna in two 40 mph moderate overlap frontal crash tests into deformable barriers. Two tests were conducted because a major fuel leak occurred in the first test. Toyota identified a defect in the manufacturing process of the plastic fuel tank and recalled the affected models. A second test was conducted to assess the effect of the manufacturing fix. For this test, Toyota retrofitted a redesigned fuel tank into the van. Due to the similarity of results (except for the fuel leak), the evaluation of the Sienna is based on both tests.

Driver restraints and dummy kinematics

Action shot taken during the second of two frontal offset crash tests.

The dummy's position in relation to the steering wheel and instrument panel after both crash tests indicates that the driver's survival space was maintained well (second test shown).<strong> </strong>.

Smeared greasepaint indicates where the dummy's head hit the B-pillar and head restraint during rebound in the second test. The head rebounded similarly in the first test. Head accelerations from these hits were low in both tests.

Intrusion into the driver's space was minimal, and forces on the legs and feet were low in both tests (second test shown).
