The present disclosure provides a control method for front and rear wheel torque distribution of an electric 4 wheel drive (E-4WD) hybrid electric vehicle. The control method includes: determining one of a fuel efficiency optimization mode and a 4WD mode from vehicle state information and driver's driving manipulation input information; calculating a driver request total torque amount; when the 4WD mode is determined, calculating a rear wheel torque amount for the 4WD; calculating a front wheel torque amount for the 4WD; calculating a front wheel engine torque amount for the 4WD; and controlling a torque output of an engine for front wheel driving and a torque output of a driving motor for rear wheel driving according to the calculated front wheel engine torque amount for 4WD and the calculated rear wheel torque amount for 4WD.
