Honda to Release All-New Accord Hybrid and Accord Plug-in Hybrid Premium Sedans in Japan

Advanced models offer ultra-high fuel economy and a completely new driving feel

Accord Hybrid fuel economy: 3.33 L/100km

Accord Plug-in Hybrid fuel economy: 1.42 L/100km

Honda Japan announced it will release the all-new Accord Hybrid on June 21 in Japan. Featuring the revolutionary new Sport Hybrid iMMD*1 powertrain, the Accord Hybrid offers refined driving worthy of a premium sedan and ultra-high fuel economy of 3.33 L/100km*2.

Based on the Accord Hybrid, the Accord Plug-in Hybrid can be charged using an ordinary household electrical outlet. Delivering spectacular fuel economy of 1.42 L/100km*3, the advanced plug-in hybrid system allows drivers to do most of their daily driving in EV mode. Also set for release on June 21, the Accord Plug-in Hybrid will be available for lease, primarily to corporations and government agencies.

The all-new Accord Hybrid features Sport Hybrid i-MMD (intelligent Multi-Mode Drive), a revolutionary Honda-developed powertrain. This advanced hybrid system belongs to the Earth Dreams Technology series of next-generation powertrain technologies, which combine enjoyable driving with outstanding fuel economy.

Sport Hybrid i-MMD uses three different engine modes to power the Accord Hybrid. For off the-line starts and low- to mid-speed cruising, EV Drive uses the battery to provide power and the drive motor to propel the vehicle. For acceleration, Hybrid Drive uses the gasoline engine to generate electricity and the drive motor to propel the vehicle. Finally, for highspeed cruising, Engine Drive uses the gasoline engine to provide power directly. By switching automatically among these three modes, Sport Hybrid i-MMD is able to deliver fuel economy of 3.33 L/100km, making the Accord Hybrid competitive with high-fuel economy mini-vehicles. In addition, the drive motor is able to produce maximum torque in off-the-line starts and Sport Hybrid i-MMD offers powerful acceleration performance and a completely new driving feel along with a smooth, comfortable ride and exceptional quietness.

Also leveraging the power of Sport Hybrid i-MMD and its high-output, high-torque drive motor, the Accord Plug-in Hybrid features a newly developed plug-in hybrid system with a high-capacity lithium-ion battery. At full charge, this battery allows the vehicle to travel up to 37.6 km in EV mode, making EV driving possible for a wide range of daily uses. Beyond the EV driving range, the Accord Plug-in Hybrid offers the same efficient cruising as the Accord Hybrid, turning in spectacular combined fuel economy of 1.42 L/100km.

 

Sport Hybrid i-MMD

Featuring a simple structure, this hybrid system comprises a newly developed exclusive gasoline engine; an electric CVT enclosing two motors (drive and generation) and a clutch directly linked to the gasoline engine; and a lithium-ion battery that efficiently stores regenerated electricity.

The system automatically selects among three drive modes to maximise efficiency at all times. The result is best-in-class*4 acceleration responsiveness and ultra-high fuel economy. The three drive modes are as follows:

 

EV Drive

  • For off-the-line starts and normal cruising, the battery provides power to the drive motor, which propels the vehicle. During deceleration, this motor serves as a generator to regenerate electricity from kinetic energy.

Hybrid Drive

  • For acceleration, the gasoline engine operates in its high-efficiency rpm range to turn the generation motor. This electricity flows to and turns the drive motor. When more powerful acceleration is needed, electricity from the battery combines with electricity from the generation motor to provide maximum torque instantaneously. The result is smooth, powerful acceleration.

Engine Drive

  • For high-speed cruising on the highway, the clutch in the transmission directly links the output axis of the gasoline engine with the drive axis of the vehicle. This mechanism makes possible high-speed cruising at the optimal gear ratio and highly efficient operation of the Atkinson cycle engine.
