A torque control system for a multi-motor range-extended electrified vehicle (REEV) having an electric all-wheel drive (eAWD) system includes a control system configured to utilize an unfiltered driver demand for engine torque determination and for predicting a front/rear axle torque split of an electrified powertrain of the REEV, the unfiltered driver demand being indicative of a torque request to be satisfied by the electrified powertrain, obtain a filtered driver demand that is damped or delayed compared to the unfiltered driver demand, and utilize the filtered driver demand for controlling a front/rear axle torque split by actuating electric motors of the electrified powertrain, wherein an engine torque delay is mitigated or eliminated thereby increasing the electrical energy to a battery system for increased availability in actuating the electric motors to control the front/rear axle torque split.
