Body Structure

Lightweight and Highly Rigid Body


1. High Strength Sheet Steel





The body of the Sienna has been made lightweight and highly rigid through the refinement of the shape and construction of each part, optimized allocation of reinforcements and members, and use of high strength sheet steel.

2. Body Shell





Reinforcements have been efficiently placed on the rockers, roof side rails, lower front pillars, and inside the center pillars to ensure proper body rigidity. As a result, road noise and vibration have been reduced and driving stability has been ensured.
