That's explicitly NOT what that is...
Edit: By "Integrated electric motor, inverter, and transmission" they mean just that. Those three components, the motor, inverter and transmission, are integrated into one housing that sits at the center of the axle both front and rear. Each one has to have a connection to each wheel, meaning four drive shafts. Since each wheel needs to move at different speeds there's literally no other way to do this aside from putting one motor in each wheel, which is not what they've done here.
