Located behind the instrument panel, the Honda Odyssey cast magnesium steering hanger beam replaces the multi-part steel unit in the previous Odyssey. Its purpose is as a structural attachment point for the steering column and instrument panel, as well as a structural element that helps the passenger cabin retain its shape in certain collisions. For the first time, the Odyssey body structure also utilizes composite materials to further reduce weight while enhancing rigidity and noise dampening. One example is inside the C-pillars, where composite stiffeners, together with the structural foam mentioned above help improve body rigidity. Another example is the base that supports the Odyssey battery. Created from a single composite casting, it holds the battery securely while adding minimal weight to the overall body structure, saving 2.9 lbs. over the previous Odyssey.
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.
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.
The 2018 Odyssey enhanced Advanced Compatibility Engineering™ (ACE™) body structure is the second generation of Honda proprietary ACE structural design. ACE is an exclusive body design that enhances occupant protection and crash compatibility in frontal crashes. It uses a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle, helping to reduce the forces transferred to the passenger compartment. It can help to more evenly disperse the forces transferred to other vehicles in a crash as well. ACE also helps reduce the chances that one vehicle will override or underride another, improving crash compatibility of vehicles that differ in size. ACE goes further by offering additional strength and protection in small overlap frontal collisions, which are among the most severe. Multiple material grades, including ultra-high-strength steel, are used in the Odyssey body construction to help optimize safety performance.
