The new Odyssey greatly benefits from a much more rigid and tightly sealed body with substantially increased use of structural adhesives and sealers, as well as new front and rear suspension subframes and extensive aerodynamic tailoring to form the basis for a quiet vehicle. Additionally, the 2018 Odyssey uses a refined, multiple-tier insulation package that takes noise, vibration and harshness (NVH) countermeasures to the next level, positioning it at the top of its competitive set.
Like other Honda V6 powerplants, the Honda Odyssey engine 4-valve cylinder heads are a single-overhead-camshaft design, with the cams driven by the crankshaft via an automatically tensioned timing belt. Made of low-pressure die-cast, low-porosity aluminum, each cylinder head incorporates a "tumble port" design that improves combustion efficiency by creating a more homogeneous fuel-air mixture. An integrated exhaust manifold cast into each cylinder head reduces parts count, saves weight, improves flow and optimizes the location of the close-coupled catalyst on each cylinder bank for quick "light off."
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).
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.
