An input shaft of the CVT unit is connected to the engine and is drivingly connected to the second input element. An output shaft of the CVT unit is connected to the first input element. The motor is connected to the output shaft of the CVT unit. According this configuration, motor torque is amplified and transmitted to the final shaft when the first clutch is engaged, while motor torque is transmit directly to the final shaft when the second clutch is engaged.
