Caitlin Duncan Honda, October 19th , 2017. 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.
Shannon Griffin Honda, October 18th , 2017. 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.

Caitlin Duncan Honda, October 18th , 2017. In a first for Odyssey, Honda Active Shutter Grille system located below the front bumper reduces aerodynamic drag especially at cruising speeds, directly helping to improve fuel efficiency. Included on all 2018 Odyssey trims, the system uses an electric actuator controlled by a processor that tracks major temperature parameters, including engine coolant and radiator temperatures, intake air temperature, transmission oil temperature and air-conditioning requirements, all of which can vary due to weather, road conditions, vehicle speed, throttle and gear positions, and towing activity. The system either opens or closes the four shutters simultaneously to control the amount of air flowing through the engine radiator and the air conditioner condenser. The system is designed to keep the shutters closed as much as possible - even in city driving.
Millie Lowe Honda, October 19th , 2017. 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.
Mollie Slater Honda, October 19th , 2017. The Odyssey new engine - from the Honda EarthDreams® Technology powertrain series - is rated at 280 peak horsepower and 262 lb.-ft. peak torque. Peak engine output is up 32 horsepower and 12 pound-feet of torque from the previous model, with increased torque over the engine entire operating (rpm) range. The new, more efficient engine and transmissions, along with as much as a 75-pound reduction in vehicle weight (EX-L trim) and improved aerodynamics, among other reductions to running resistance, result in enhanced performance and fuel efficiency. With its 60-degree V-angle, the Odyssey V6 engine is inherently smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The engine has a high-pressure die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The engine also uses a high-tensile strength steel crankshaft is for minimum weight.
Paige Dodd Honda, October 19th , 2017. 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.
Caitlin Duncan Honda, October 19th , 2017. 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.
Eleanor Norton Honda, October 19th , 2017. The new Odyssey makes widespread use of structural adhesives in the unit-body, supplementing structural welds and significantly increasing rigidity without the additional mass of steel components. Structural adhesives are used at the roof edges and around the moonroof opening, in the front floor and cowl area, in the A- and B-pillars, around the front suspension upper mounts, and extensively throughout the rear of the body. Applied before the body panels are welded together, some 147.6 feet of adhesives (32.8 ft. more than in the previous Odyssey generation) account for approximately 3.5 percent of the entire unit-body stiffness.
Shannon Griffin Honda, October 19th , 2017. Included on the Odyssey LX, EX, EX-L and EX-L N/R, projector-beam-style halogen headlights feature round outboard low beams and round inboard high-beam illumination. The Odyssey LX headlights have an auto-off feature to protect the battery state of charge if the driver leaves the vehicle without switching off the lights, while Odyssey EX and above trims add the convenience and safety of auto on/off high beams (AHB).
