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.
