Nissan’s one-motor two-clutch hybrid system wins the Contribution Prize of Ichimura Prizes in Industry

Nissan Motor won the Contribution Prize of the Ichimura Prizes in Industry hosted by the New Technology Development Foundation for the development of the one-motor two-clutch parallel full-hybrid system. (Earlier post.)

The Ichimura Prizes in Industry, which is in its 44th year, is given annually to an excellent technology developer or an excellent group of technology developers who contributed to or achieved development in the industrial field. The award is given to outstanding technologies in various business fields in Japan. Nissan is the only automotive manufacturer awarded a prize this year.

The foundation recognized Nissan’s one-motor two-clutch parallel full-hybrid system due to its lightweight system and simple structure. The system was developed for passenger vehicles, yet it achieves compact-car-level fuel-efficiency while enabling acceleration performance and drivability equivalent to a vehicle equipped with a V8 engine. This hybrid system is available in the Infiniti M and Nissan Fuga models.

Prior to the Nissan development, hybrid systems with torque convertors were preferred over clutch systems in order to achieve smooth operation. However, Nissan engineers were able to achieve the desired smooth driving characteristics with motor and clutch control technology, high-output, high-response lithium-ion batteries and other technologies. This one-motor two-clutch parallel hybrid system—available in passenger cars for the first time ever—delivers more frequent use of the motor in high-speed and normal operation while the driver enjoys the exhilarating performance.

Nissan’s one-motor two-clutch parallel full-hybrid system has also won the following engineering awards:

  • The 61st JSAE Awards, the Technological Development Award by the Society of Automotive Engineers of Japan (May, 2011)

  • The 9th New JSPMI Prizes, Chairman’s Prize by the Japan Society for the Promotion of Machine Industry (February 24, 2012)

  • FY2011 Medal for New Technology by the Japan Society of Mechanical Engineers (To be given in April, 2012)



Cars have had a electric motor since the first electric starter system in 1913. Finally, it's bigger.

Yes Virginia, there IS a replacement for displacement.

..only a hundred years and not from US auto God, the agility..


Nissan and Honda both have some good patents on their new motor designs. It looks like Nissan may be developing a different design from the Toyota type design on the Altima hybrid.


HEVs components and design will continue to evolve for another decade or so or until replaced by PHEVs and BEVs. Some design features will be useful for the latter.
