Reasons Behind Systems High Performance
1. For Lightweight system, 1 Motor system -> 1 Motor operates both propulsion and generation
2. For Fuel economy, decoupling V6 engine in EV drive mode -> Equipped Clutch-1 between engine and motor
3. For Fuel economy and DIRECT RESPONSE, no torque converter -> Clutch-2 Control and Motor torque in place of torque converter

Low- / Mid-speed
Fuel Efficiency Improved efficiency by connecting/disconnecting engine
Frequent EV drive can be realized without engine friction to separate from the engine by the clutch
Mid- / High-speed
The engine can be used in the efficient operation range by generating power with the motor and the high final gear ratio
Highly efficient because the clutch transmits engine torque directly
Deceleration (regenerating)
Efficient motor-regenerating by disconnecting engine and eliminating engine friction
Efficient charging by Li-ion battery when regenerating

Lithum-ion battery
Achieves direct feel and good response by use of high-speed, precise motor control and a Li-ion battery capable of providing high power immediately
Linear and direct feeling due to motor assist and torque converter-less transmission
Adopted and enhanced the rev-matching technology onto the motor control
Power assist without compromising drivability by using compact Li-ion battery
Full acceleration/shifting (motor-assisted)
