Two drive systems
Depending on the driver-selected drive mode and available electric energy, the two drive systems can be used either individually or in parallel.Both the internal combustion engine and electric motor can generate motive force directly to the wheels. An advanced control system combines the properties of both drive systems in order to provide optimum driving economy.

- Hybrid battery – The function of the hybrid battery is to store energy. It receives energy when charging from the mains power circuit, during regenerative braking or from the high-voltage generator. It provides energy for electric operation as well as for temporarily operating the electric air conditioning during the preconditioning of the passenger compartment.
- Internal combustion engine – The internal combustion engine starts when the energy level in the hybrid battery is insufficient for the engine power that the driver requests.
- High voltage generator – Charges the hybrid battery. Starter motor for the internal combustion engine. Can support the internal combustion engine with extra electrical energy.
- Electric motor – Powers the car in electric operation. If necessary, provides extra torque and power during acceleration. Provides electrical all-wheel drive functionality. Recycles brake energy to electrical energy.
