Drive systems
Volvo Twin Engine combines a gasoline engine with an electric motor.
Two drive systems
Depending on the selected drive mode and power available in the electric motor, the drive systems can either be used separately or in tandem.
The electric motor gets its energy from a hybrid battery located under the tunnel console. The hybrid can be charged from a wall outlet or in a special charging station.
Both the combustion engine and the electric motor can generate power directly to the wheels. An advanced control system coordinates both the drive systems to help optimize driving economy.
Hybrid battery - The hybrid battery's function is to store electrical current. This current is provided by plugging the charging cable into an electrical outlet or through regenerative braking. This provides current to power the electric motor and to temporarily power the electrical air conditioning to precondition the passenger compartment.
Combustion engine - The combustion engine starts when the charge level in the hybrid battery is too low to provide the power output requested by the driver.
Super capacitor – Supplies current to start the vehicle, which saves current in the regular 12 V battery.
Electric motor - Powers the vehicle using electricity. Can provide extra torque and power during acceleration. Regenerates braking energy into electrical current.
