An electric vehicle to automatically adjust output torque during travelling even when there is a difference in the output characteristic between two traction motor units that independently drive left and right drive wheels. The electric vehicle includes the motor units; a torque command unit that outputs torque command values to the motor units; a torque difference occurrence determiner that determines that a difference has occurred between actual driving forces TL, TR of the respective drive wheels even when the torque command unit applies the same torque command values TL*, TR* to the motor units; and a driving force difference reducer that, if the determiner determines that a driving force difference not less than a set value has occurred between the drive wheels, causes control of reducing the driving force difference to be performed during travelling.
