Located under the front floor of the new Honda Odyssey is a variation of the "3-Bone" structure used in the Pilot that improves impact load management, directing energy around the passenger cabin in the event of a frontal collision. The structure creates three different load pathways, or "backbones," that channel collision energy. One channels collision forces from the front of the vehicle directly underneath the passenger cabin; the other two channel collision forces under the vehicle left and right side frames. The result is an improved capability to safely channel energy during a frontal crash.
To further improve emissions compliance, the 3.5-liter V6 makes use of an after-catalytic-converter exhaust gas recirculation (EGR) system that allows cleaner, cooler EGR gas to be fed back into the intake system. An EGR system, especially one that delivers a cleaner, cooler charge, reduces pumping loss for better fuel efficiency. With its 60-degree V-angle and compact, rigid and lightweight high-pressure die-cast aluminum cylinder block assembly, the 3.5-liter V6 powerplant is exceptionally smooth during operation. Other factors that help reduce engine noise and vibration are a rigid forged-steel crankshaft, die-cast accessory mounts, and a stiff cast-aluminum oil pan that reduces cylinder block flex.
The new Honda Odyssey includes an underbody aero package consisting of a 2-piece undercover behind the front fascia and underneath the engine and transmission, flat underbody surfaces extending between the front and rear wheel areas, air-diverting strakes positioned ahead of all four tires, and an additional undercover behind the left rear tire (the tailpipe occupies the space behind the right rear tire). These undercovers directly improve fuel efficiency, particularly on the highway.
Based on Honda global light truck platform, the 2018 Odyssey body structure has 44-percent greater torsional rigidity than the previous model. High-strength steel comprises 58 percent of the body structure, contributing to both improved stiffness and reduced mass for the unit-body. Stiffening the body with ultra-high-strength steel, hot-stamped steel and adhesives in critical areas likewise directly contribute to reduced noise and vibration, and improved ride and handling. The structural improvements also help reduce mass, directly contributing to increased fuel efficiency.
