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.
The Odyssey V6 engine combines Variable Cylinder Management (VCM) with Variable Valve Timing and Lift Electronic Control (i-VTEC), which changes the lift profile, timing and lift duration of the intake valves. A switching mechanism allows each cylinder to operate with low-rpm valve lift and duration or high-rpm lift and duration. While operating in 3-cylinder mode, the rear cylinder bank rocker arms deactivate, closing all intake and exhaust valves to minimize pumping losses. The "intelligent" portion of the system is its ability to vary valve operation based on the driving situation and engine rpm. At low rpm, the i-VTEC intake valve timing and lift are optimized (low lift, short duration) for increased torque, which allows a wide range of 3-cylinder operation. As engine rpm builds past 5,350 rpm, the i-VTEC system transitions to a high-lift, long-duration intake cam profile for superior high-rpm engine power.
The 2018 Odyssey receives the most thorough and intensive array of aerodynamic refinements of any Odyssey generation to date. This comprehensive approach boosts aerodynamic efficiency and reduces wind noise. Examples of the aero efforts found on the 2018 Odyssey include extensive under covers, the Active Shutter Grille system, hidden windshield wipers, wind-sculptured side mirrors (power folding on Elite), and many small but pertinent details such as under-body strakes, shark fin-type antenna, and a rear spoiler (black on LX, EX, EX-L and Touring trims, body-color on Elite).
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.
