An electric drive system for a vehicle, such as a rail vehicle, has a plurality of different drive motors. The motors include at least one permanently excited motor as a drive and at least one further motor selected from the group of asynchronous motor and reluctance motor as a drive motor. The permanently excited motor is powered by an inverter whose power semiconductor has a greater band gap than silicon, and the further motor which is selected from the group of asynchronous motor and reluctance motor is powered by an Si inverter.
