Development of new, high efficiency powertrain units for hybrid vehicles

We developed new powertrain units, P210 and Q210 rear transaxle for Mini-van Hybrid 4WD vehicles. They have achieved excellent performance in fuel economy. In P210 equipped with a motor driving the front wheels and Continuously Variable Transmission (CVT), our efforts were to reduce the driveline drag and the energy loss of the hydraulic control system, and also to highly integrate the CVT control scheme to the hybrid power management. For Q210, a motor is used to drive the rear wheels with the aim of reducing drag while optimizing the opportunity for 4WD operation.
