    Patent number: 9616738
    Abstract: A hybrid vehicle includes an engine: a regenerative motor for use when the hybrid vehicle runs, the motor having characteristics such that motor efficiency is 90% or more at a rotational speed of 1.5 times of a rotational speed of the motor where the motor efficiency is highest when the load of the motor is 10% or more of the maximum load of the motor; and a transmission which transmits the power of the engine to a wheel drive shaft. The motor is coupled to the wheel drive shaft without being coupled to the transmission.
