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

Motor

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)
