Drive systems

Volvo's Twin Engine combines an internal combustion engine that drives the front wheels with an electric motor that drives the rear wheels.

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.

The electric motor is supplied its energy from a hybrid battery fitted in the tunnel console. The hybrid battery can be charged in a wall socket, or in a special charging station. The internal combustion engine can also charge the hybrid battery with a special high-voltage generator.

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.

P5-1717-XC60H-Hybrid drive system
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

CISG (Crank Integrated Starter Generator) - Combined high-voltage generator and starter motor.

- 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.
