A method of improving braking performance through motor torque control of a vehicle includes: determining a relation between a vehicle wheel torque change amount and a driving acceleration change amount prior to a start of braking of the vehicle; calculating a target acceleration that is changed according to a driver's braking request when a driver presses a brake pedal to start the braking of the vehicle; detecting a real acceleration of the vehicle in real-time; comparing the real acceleration with the target acceleration; and compensating for a difference between the real acceleration and the target acceleration by increasing a regenerative braking amount through motor torque control when the real acceleration differs from the target acceleration.
