In a vehicle of the invention, a sun gear, a carrier, and a ring gear of a planetary gear mechanism are respectively connected to a first motor, to an engine, and to a drive shaft and a second motor. When the combination of measured accelerator opening and measured vehicle speed is in an ordinary acceleration area, the vehicle of the invention sets a torque demand to decrease with an increase in measured vehicle speed at a specific reduction rate that ensures the substantially constant output power to the drive shaft corresponding to the accelerator opening. When the combination of the measured accelerator opening and the measured vehicle speed is in an acceleration feel improvement area, on the other hand, the vehicle of the invention sets the torque demand to an extent of or below a maximum allowable value of the torque demand to decrease with an increase in measured vehicle speed at a lower reduction rate than the specific reduction rate. The lower reduction rate decreases against the accelerator opening closer to a center opening. The torque demand in the acceleration feel improvement area is also set to increase with an increase in measured vehicle speed with regard to the accelerator opening practically equal to the center opening. The vehicle controls the engine and the first and the second motors to ensure output of a torque equivalent to the torque demand to the drive shaft.
