A circuit budgets torque among independent field-oriented motor control circuits. A desired vehicle yaw turning moment is received from an operator control input. The circuit determines a positive or negative torque target for each electrically powered drive wheel and transmits it to an adaptive field-oriented motor control circuit which provides voltage magnitude and voltage frequency to a poly-phase synchronous alternating current electric motor. When wheel loading, limited traction, or stability prevents any motor from attaining the torque target, that data is returned to the budgeting circuit and torque budget is adjusted for all adaptive field-oriented motor control circuits. Varying numbers of powered wheels are assigned torque depending on vehicle dynamics. Performance of the vehicle can be adapted to driver capabilities. A vehicle may serve as a driving simulator for diverse vehicles.
