A four-wheel drive vehicle includes: (a) main drive wheels and auxiliary drive wheels; (b) a rotating machine as a drive power source; (c) a drive-power distribution clutch configured to allocate a part of a drive power outputted to the main drive wheels from the drive power source, to the auxiliary drive wheels, so as to distribute the drive power to the main drive wheels and the auxiliary drive wheels with a drive-power distribution ratio between the auxiliary drive wheels and the main drive wheels, such that the drive-power distribution ratio is variable with an engaging force of the drive-power distribution clutch being controlled; and (d) a control apparatus configured, when determining that a heat load of the drive-power distribution clutch is large during deceleration running of the vehicle, to limit a regenerative torque of the rotating machine, as compared with when determining that the heat load is small.
