The present invention provides a front-and-rear-wheel-drive vehicle which can reduce weight and cost of a vehicle while maintaining ability to travel at high speed. A vehicle (10) comprises a front motor (41) which drives front wheels (11), a rear motor (51) which drives rear wheels (12) and has a maximum torque greater than a maximum torque of the front motor (41), a front-wheel speed reducer (43) which reduces rotation of the rear motor (51) and transmits the reduced rotation to the front wheels (11), a rear-wheel speed reducer (53) which reduces rotation of the rear motor (51) at a speed reduction ratio smaller than a speed reduction ratio of the front-wheel speed reducer (43) and transmits the reduced rotation to the rear wheels (12). The speed reduction ratios of the front and rear-wheel speed reducers (43, 53) are set in a manner that a maximum rate of rotation of the rear wheels (12) is greater than a maximum rate of rotation of the front wheels (11).
