Conflicting customer demands for reduction of CO2 emissions (fuel economy improvement) and enhancement of driving pleasure are continuing to become more rigorous all the time. Against this backdrop, JATCO launched the transmission for hybrid system with Nissan in 2010, followed by the development of a hybrid system for use on a front-wheel-drive midsize SUV in the North American market. Among the various types of hybrid systems proposed to date, this one-motor two-clutch (1M2CL) parallel hybrid system achieves high efficiency with no engine friction loss during the EV mode and energy regeneration. This paper describes the new Jatco CVT8 HYBRID (CVT8 HYBRID), it is newly developed packaging technologies for compactly mounting the 1M2CL parallel hybrid system on front-wheel-drive vehicles.
