Subaru Hybrid System
Creeping conditions: EV operation
Driving slowly with just the motor itself(*4).
Taking off and low-speed driving: EV operation
At low engine speeds where ordinary engines operate at low efficiency, only the motor itself is used for driving(*4). This produces a new driving sensation that is quiet and nimble.
Accelerating and medium-speed driving: motor-assist operation
The engine starts operating and the motor assists with driving. Great acceleration is achieved with two power units working in tandem.
High-speed driving: engine operation
At high engine speeds where ordinary engines operate at a higher efficiency, only the engine is used for driving. The motor is used when required to generate electricity and recharge the battery.
Decelerating: regenerative braking
When braking or if the accelerator pedal is not being used, deceleration energy is converted to electricity to recharge the battery efficiently. The system also provides a completely natural braking feel.
Stopping: idle stop
Pressing the brake to stop the car will automatically stop the engine(*5). This helps to limit wasted fuel consumption.
*4: The engine might restart depending on driving conditions.
*5: The engine might not stop depending on driving conditions.
* Various different conditions affect system operation, which may differ depending on driving conditions or the state of the car.
