A system and a method for reducing the acceleration shock of an electric motor vehicle are provided. A backlash torque range is determined based on a coast down value indicating the motor torque for maintaining a vehicle speed. A slope of the motor torque that falls within a backlash torque range is reduced and corrected, considering that the motor torque for causing backlash is changed as the motor speed changes, thereby reducing the shock due to the backlash at the acceleration (start-up) of a vehicle.
