The 2018 Honda Odyssey 3.5-liter V6 engine meets the tough EPA Interim Tier 3/Bin 125 and CARB LEV3/ULEV-125 emissions standards, and is certified to this level of emissions performance for 150,000 miles. Numerous advanced technologies are factors in the emissions performance. The unique cylinder head-mounted close-coupled catalytic converters light off quickly after engine start up, and a 32-bit RISC microprocessor within the Electronic Control Unit (ECU) boosts computing power to improve the precision of spark and fuel delivery. The engine features Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.
Located under the front floor of the new Honda Odyssey is a variation of the "3-Bone" structure used in the Pilot that improves impact load management, directing energy around the passenger cabin in the event of a frontal collision. The structure creates three different load pathways, or "backbones," that channel collision energy. One channels collision forces from the front of the vehicle directly underneath the passenger cabin; the other two channel collision forces under the vehicle left and right side frames. The result is an improved capability to safely channel energy during a frontal crash.
The 2018 Honda Odyssey incorporates a wide range of halogen and light-emitting diode (LED) exterior lighting features. LED headlights are available for the first time, joining available LED Daytime Running Lights (DRL), available LED side mirror turn signals and LED taillights to provide the brightest and most visually distinctive array of Odyssey exterior lighting yet.
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.
