A hybrid vehicle is provided which can produce a decelerating force without detriment to drive quality. The hybrid vehicle includes an internal combustion engine, an electromechanical unit, an electric motor, a decelerating operation detecting unit for detecting that a decelerating operation has been performed, a differential gear unit having at least a first gear element connected to the electromechanical unit, a second gear element connected to an output shaft and a third gear element connected to the internal combustion engine, an engine controller for bringing the internal combustion engine into a non-driving state when it is detected by the decelerating operation detecting unit that a decelerating operation has been performed. When it is detected by the decelerating operation detecting unit that a decelerating operation has been performed, the internal combustion engine is brought into the non-driving state, and the electromechanical unit control unit controls the electromechanical unit so as to compulsorily rotate the internal combustion engine.
