VDC electronic stability control utilizes sensors which constantly monitor wheel speed, steering angle, brake pressure, vehicle yaw rate and lateral g-forces. If VDC detects a difference between the driver's intended path and the one the vehicle is actually taking, VDC applies braking power and/or reduces engine torque to help correct vehicle path. Exclusive to WRX STI, VDC features Standard, Off and Performance-oriented Traction modes.

VDC also incorporates an all-wheel, all-speed traction control system which, when sensing a loss of traction, applies braking force and reduces engine torque to the slipping wheel or wheels as necessary to maintain vehicle motion.
