A control system configured to control a rotating electrical machine of a battery electric vehicle (BEV), having one or more microprocessors that execute a low-efficiency mode of operation for the BEV, such that the low-efficiency mode of operation includes determining a high-efficiency mode current command corresponding to operation at a determined physical rotor angular velocity of a rotor of the rotating electrical machine at a commanded torque value, and increasing current supplied to the rotating electrical machine to a level corresponding to operation at an angular velocity higher than the determined physical angular velocity of the rotor at the commanded torque value.
