![]() The gasoline engine is off when the i-MMD is in EV Drive mode and is decoupled from the drivetrain to reduce friction. An animated visual display of current operation power flow, including regeneration, can be displayed on the Multi-Information Display (MID) in the center of the instrument cluster.Īll-electric drive EV Drive operation occurs when starting from a stop, during light cruising and acceleration, and when braking. The Accord Hybrid's powertrain shifts seamlessly and smoothly among the three driving operations, utilizing power from the Atkinson-cycle i-VTEC® 4-cylinder engine and the electric motor to suit the driving conditions moment to moment. To help maximize efficiency on the road, the Accord Hybrid seamlessly shifts between three distinct drive operations: EV Drive (100 percent electric motor), Hybrid Drive (electric motor and gasoline engine ) and Engine Drive (gasoline engine). Detailed energy management for each component, as controlled by the Power Control Unit (PCU), enables this system to make the best use of both the electric propulsion motor and the gasoline engine to seamlessly provide smooth and responsive performance and to garner top EPA fuel economy ratings in the midsize hybrid sedan class. The 2017 Accord Hybrid's second-generation i-MMD two-motor hybrid system is a highly efficient powertrain that selects the optimal drive operation under a wide range of driving conditions to combine a fun-to-drive character with excellent fuel efficiency. Second-Generation Intelligent Multi-Mode Drive (i-MMD) Two-Motor Hybrid System 24-hour roadside assistance (during initial warranty period).Eight-year/100,000-mile or ten-year/150,000 mile Li-Ion battery limited warranty, depending on the state of purchase/registration.Electric motor output: 181 hp (up from 166 hp).100,000+/- miles engine tune-up interval.Close-coupled dual bed catalytic converter.i-VTEC® (Variable Valve Timing and Lift Electronic Control) + Electric VTC.Gasoline engine output: 143 hp (up from 141 hp).Two-Motor Intelligent Multi-Mode Drive (i-MMD) Hybrid System Features These EPA fuel economy ratings are based on new, more stringent ratings requirements enacted by the U.S. The Accord Hybrid has EPA fuel economy ratings of 49/47/48 mpg (city/highway/combined) – giving it by far the best-in-class ratings for midsize hybrid sedans. The result of the 2017 Accord Hybrid's cutting-edge powertrain technology is a fun-to-drive character, aided by a new Sport mode and an 8.2 percent increase in total system power to 212 horsepower (as measured by the peak, concurrent output of the two electric motors and gas engine), coupled with fuel efficiency unmatched in its segment. Furthermore, to enhance the fun factor, the i-MMD includes a new Sport mode. These second-generation refinements reduce weight, size and complexity, and increase power and efficiency, all of which have packaging and performance benefits. In Engine Drive Mode, used mainly during medium- to high-speed cruising, the vehicle can operate on gasoline engine power only.Ĭhanges to the two-motor i-MMD for the 2017 Accord Hybrid include upgrades to the gasoline engine, electric generator, electric motor, Power Control Unit (PCU), Intelligent Power Unit (IPU) and lock-up clutch. Under certain conditions, the Accord Hybrid can operate on electric power only, with the engine shut off. Under most conditions, the vehicle operates in Hybrid Drive mode, in which the gasoline engine operates as a generator, supplying electric power to the hybrid batteries, with motive power supplied by the electric propulsion motor. Honda's second-generation i-MMD uses a two-motor hybrid approach with three operating modes – EV Drive, Hybrid Drive and Engine Drive – responding to the demands of the driver while maximizing fuel efficiency. ![]() This sophisticated, refined and seamlessly operating system further extends the Accord Hybrid's advantages over its competitors with even more power and fuel efficiency. Offering a significant powertrain upgrade from the previous Accord Hybrid, the 2017 model features the second-generation Intelligent Multi-Mode Drive (i-MMD) two-motor hybrid powertrain.
