The strength of the "tailgate ring" (the circular metal structure surrounding the tailgate) is vitally important for superior vehicle handling, stability and ride quality. Debuting on the 2016 Honda Pilot and applied to the 2018 Odyssey for the first time, this advanced tailgate ring contributes to the new model gain in torsional rigidity, benefiting ride, handling and NVH. For the first time in the Odyssey, body stiffness is enhanced using structural foam inserts in key locations. These include the left and right C-pillar stiffeners, and within an inside bracket that connects the left and right side center frames under the front floor. The improved body stiffness pays dividends in handling precision, ride quality, NVH and crash safety.
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 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.
The Honda Odyssey new direct-injection system enables increased torque across the engine full operating range along with higher fuel efficiency. The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in the previous generation Odyssey), allowing for more efficient combustion. The multi-hole injectors can create the ideal stoichiometric fuel/air mixture in the cylinders for good emissions control. Theoretically, a stoichiometric mixture has just enough air to completely burn the available fuel. Based on the operating conditions, the direct-injection system alters its function for best performance. Upon cold engine startup, fuel is injected into the cylinders on the compression stroke. This creates a weak stratified charge effect that improves engine start-up and reduces exhaust emissions before a normal operating temperature is reached.
