Caitlin Duncan. Honda. October 19th , 2017.
For the first time, the new 2018 Odyssey has 1500-megapascal (MPa) ultra-high-strength steel door reinforcement beams and ultra-high-strength front door outer stiffener rings made of 1500-MPa hot-stamped steel. Laser welded and significantly stronger than ordinary steel, the ultra-high-strength steel reinforcements are designed to help better protect occupants in a frontal or side impact. Their increased strength allows the components to be made lighter which also helps reduce overall vehicle weight for improved fuel efficiency.
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.
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).
To provide extra sound insulation by blocking off hollow pillars, acoustic spray foam is applied in 14 locations in the Odyssey body for the first time in Honda history. The areas include the base of the A-, B-, C- and D-pillars, as well as the base of the windshield frame and at the top of the C- and D-pillars. In addition, acoustic tape is applied at base of the A-, B- and C-pillars, and a foam stopper is applied to the bottom of the B-pillar. Altogether, the use of these body sealing techniques results in a 55-percent reduction in body leaks, which significantly reduces noise entering the cabin in critical sections. All foam and acoustic tape application is done while the unit-body is in its just manufactured "body-in-white" form - before attachment of key components and assemblies.
