An optimized control system for a multi-motor propulsion system of an electrified vehicle is configured to access a calibrated surface that defines operating points corresponding to different torque requests and for enabling/disabling first and second electric traction motors of an electrified powertrain, determine an operating mode for the electrified powertrain based on the torque request and the calibrated surface, wherein the operating mode is one of (i) enabling the first electric traction motor and disabling the second electric traction motor, (ii) enabling the second electric traction motor and disabling the first electric traction motor, and (iii) enabling both the first and second electric traction motors, and control the electrified powertrain according to the determined operating mode such that the one or more enabled electric traction motors satisfies the torque request and thereby improves an efficiency of the electrified powertrain.
