摘要： A front-and-rear-wheel-drive vehicle includes first and second electric drive motors which drive front and rear wheels, the second electric drive motor has a maximum torque greater than that of the first electric drive motor, a first speed reducer which reduces rotation of the first electric drive motor, a second speed reducer which reduces rotation of the second electric drive motor at a speed reduction ratio smaller than that of the first speed reducer, the speed reduction ratios of the first and second speed reducers are set in a manner that a maximum rate of rotation of one of the front and rear wheels corresponding to that of the second electric drive motor is greater than a maximum rate of rotation of the other wheel corresponding to that of the first electric drive motor.
