The new engine marks Honda's first naturally aspirated DOHC V6 without VTEC since the original NSX. However, unlike the NSX's engine, the Pilot's V6 (engine code J35Y8) does not have VTEC's innovative variable valve timing system, which utilized two camshaft profiles for low-RPM efficiency and high-performance activation at a certain RPM. Instead, it utilizes cam phasers that continuously adjust timing for both intake and exhaust valves, resulting in a smoother power delivery. Power increases by 5 horses to 285 and torque remains at 262 pound-feet, both arriving at a slightly higher RPM.
The heads of the new V6 engine are borrowed from the TLX Type S and MDX Type S, featuring cast cam bearing caps in the valve covers to reduce the overall engine height by 1.2 inches. The direct-injection system has also been improved with a 50% increase in pressure, allowing for more controlled fuel delivery and three injections of gasoline per combustion cycle. This results in a 40-50% decrease in NOx and particulates, earning the V6 an SULEV30 rating for super-ultra-low-emissions according to 2030 standards.
Honda's focus with the new V6 was to improve fuel efficiency, not performance. As such, it is expected to be incorporated into Honda's large SUVs until the arrival of its electric vehicles.
