This application discloses a powertrain system and an electric vehicle, to reduce a structure size of the powertrain system. The powertrain system includes two subsystems. The two subsystems are disposed side by side in a first direction and are symmetrical to each other. Each of the subsystems includes a motor, a deceleration mechanism, and an output shaft. A rotation shaft of the motor is disposed in a second direction. The deceleration mechanism includes a cylindrical gear pair and a bevel gear pair. The cylindrical gear pair includes an active cylindrical gear and a driven cylindrical gear, and the active cylindrical gear is connected to the rotation shaft of the motor. The driven cylindrical gear is located on a side that is of the active cylindrical gear and that is away from the other subsystem. The bevel gear pair includes an active bevel gear and a driven bevel gear. The active bevel gear is located on a side that is of the driven cylindrical gear and that is close to the motor, a small end of the active bevel gear is disposed close to the motor, and the active bevel gear is connected to the driven cylindrical gear. The driven bevel gear is located on a side that is of the motor and that is away from the other subsystem, and the driven bevel gear is transmittedly connected to the output shaft.
