A flat towing technique for an electrified vehicle includes in response to a request for and during a flat towing operation, monitoring at least a back electromotive force (EMF) generated by an electric motor of the electrified powertrain, performing field weakening control of the electric motor such that the back EMF generated by the electric motor during the flat towing operation maintains a high voltage bus that powers the electric motor at a target voltage level, selectively isolating a high voltage battery system of the electrified powertrain from the high voltage bus based on a desired capacity of the high voltage battery system, and adjusting the target voltage level for the high voltage bus based on respective lower limits for electric motor speed and high voltage bus voltage and when the high voltage battery system is isolated from the high voltage bus.
