A control device that controls an internal combustion engine, a first rotary electric machine, a first engagement device, and a second engagement device performing first transition control when transition is performed from a first mode to a second mode. The first transition control includes first control, second control, and third control. The first control is control in which the second engagement device that connects and disconnects power transmission between two rotary elements selected from among three rotary elements of a distribution differential gear mechanism is changed from an engaged state to a disengaged state while a third engagement device of a transmission mechanism is maintained in an engaged state. The second control controls a rotational speed of the first rotary element to is changed from a disengaged state to an engaged state and the internal combustion engine is started by using drive power transmitted from the first rotary electric.
