1. An electric vehicle, comprising:
a drive motor configured for generating power required for driving of the vehicle;
a twin clutch that includes a first clutch and a second clutch and configured to adjust distribution of the power supplied from the drive motor to a first drive wheel and a second drive wheel of the vehicle through the first clutch corresponding to the first drive wheel and the second clutch corresponding to the second drive wheel; and
a controller electrically connected to the twin clutch and configured to, when a control condition for a deceleration turning of the vehicle is satisfied, determine a control torque of the twin clutch as a larger value of an initial torque to prevent slip of the twin clutch and a base torque determined based on output torque of the drive motor, and distribute the control torque to the first clutch and the second clutch depending on a drive mode of the vehicle in a clutch torque distribution rate.
