A powertrain system for an electric automobile outputs a desired torque from a motor with an angle of an accelerator pedal that is easy for a driver to operate, regardless of traveling environments such as the road surface gradient and the wind direction. The powertrain system includes a paddle switch and a shifter that are mounted to be operable by a driver, and are electrically connected directly or indirectly to an electronic control unit (ECU). The ECU controls, based on a torque control map defining the relationship between an accelerator pedal opening and output torque of a motor in advance, the output torque of the motor according to the accelerator pedal opening, and changes, based on an operation on the paddle switch or the shifter, the torque control map to be used for controlling the output torque of the motor.
