Located behind the instrument panel, the Honda Odyssey cast magnesium steering hanger beam replaces the multi-part steel unit in the previous Odyssey. Its purpose is as a structural attachment point for the steering column and instrument panel, as well as a structural element that helps the passenger cabin retain its shape in certain collisions. For the first time, the Odyssey body structure also utilizes composite materials to further reduce weight while enhancing rigidity and noise dampening. One example is inside the C-pillars, where composite stiffeners, together with the structural foam mentioned above help improve body rigidity. Another example is the base that supports the Odyssey battery. Created from a single composite casting, it holds the battery securely while adding minimal weight to the overall body structure, saving 2.9 lbs. over the previous Odyssey.
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.
The Odyssey Electronic Control Unit (ECU) monitors engine functions to determine the best ignition spark timing. Two engine block-mounted acoustic detonation/knock sensors "listen" to the engine, and based on this input, the ECU can retard the ignition timing to prevent potentially damaging detonation. The engine has an ignition coil unit for each cylinder positioned within each spark plug access bore. To help improve fuel efficiency, the Odyssey Touring and Elite are equipped with Idle-Stop capability. When the system is enabled by the driver and certain operating conditions are met, the Idle-Stop system will automatically shut off the engine when the vehicle comes to a stop. The engine is automatically restarted when the driver releases the brake pedal after a stop, or if the steering wheel is turned. If the Brake Hold system is in use, the engine quickly restarts after the throttle is depressed.
Wiper-linked auto on/off headlights are included on the Odyssey EX and above trims. When the headlight function is set to the AUTO mode, the headlights turn on after the wipers have completed five wipe cycles; they then automatically turn off 2 ½ minutes after the last wipe. Included on the EX and above trims, Smart Entry simplifies approaching, entering and operating the Odyssey - especially when the driver has his or her hands full. To gain entry to vehicle, the driver simply pulls one of the two front door handles while the remote is in his or her possession. The 2018 Odyssey LX retains the previous remote entry system.
