A dual-motor electric vehicle (EV) drive system is provided that employs two different types of electric motors; at least one permanent magnet synchronous motor and at least one induction asynchronous motor. Under most low demand driving applications the EV relies on the permanent magnet motor(s), thus benefiting from the operating efficiency of this type of motor. Under high demand driving applications, for example during strong acceleration and high speed cruising, the EV is able to benefit from the output power capabilities of the induction motor(s).
