Motor plus engine.
Double power for smart operation.
So that the engine always operates at maximum efficiency, the motor provides backup and recovers surplus energy.
By efficiently switching between the two power sources, the vehicle combines high fuel efficiency with a comfortable driving style.
How It Works
Startup and low-to mid-speed range
Motor operation with outstanding energy efficiency and low-speed torqueIn normal cruising from vehicle start up to the mid-speed range, where engine efficiency is poor, the engine is shut off and the vehicle operates with the high-output motor alone (ⓐ).
High fuel efficiency operation using the engine as the main power sourceEngine power is divided between two systems by a power split device. One of these systems drives the generator to produce electricity, which in turn drives the motor (ⓑ). The other directly powers the wheels (ⓒ). The relative power distribution between the two systems is controlled to ensure maximum efficiency.
The two power sources provide the acceleration of a vehicle one class higherDuring rapid acceleration, electric power is also supplied by the battery. By adding the drive power from the high-output motor to the drive power from the engine, the vehicle delivers highly responsive and smooth dynamic performance for further enhanced acceleration performance (ⓐⓑⓒ).
Deceleration and braking
Deceleration energy is recovered by the batteryDuring deceleration and braking, the wheels drive the motor. This means that the high-output motor operates as a high-output generator to convert the vehicle braking energy into an additional source of electric power. This highly efficient process is known as regenerative braking, with the recovered electric power used to recharge the high-performance battery (ⓓ).
Constant battery charge level is maintainedWhen the battery charge level is low, starting the engine switches the generator on, and recharging begins. This system operates to maintain a constant charge level (ⓔ).
All power systems are shut downThe engine switches off automatically.
