In a hybrid vehicle 20, when the ECO switch 88 is turned on, an intermittent permissive ceiling speed Vref for permitting an intermittent operation of an engine 22 is set to a second vehicle speed more than a first vehicle speed used on a turn-off condition of the ECO switch 88 (S130). The engine 22 and a motor MG2 are controlled so that a driving power equivalent to a torque demand Tr* is ensured with the intermittent operation of the engine 22 when a vehicle speed V is not more than the intermittent permissive ceiling speed Vref (S250,S270,S200-S230).
