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.
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).
Multiple grades of high-strength steel are used in the Odyssey body construction to help achieve excellent overall vehicle dynamics, optimize safety performance, reduce weight, and lower noise, vibration and harshness (NVH). The combination of advanced materials and evolved engineering processes save 75 lbs. in unit-body weight compared to the previous-generation Odyssey. The 2018 Honda Odyssey features several unique advancements in body design and materials that significantly improve overall rigidity, while reducing weight. This directly helps improve overall vehicle dynamics, crash safety performance, interior quietness, and long-term durability.

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.
