SYMMETRICAL ALL-WHEEL DRIVE
WRX models utilize a viscous-type locking center differential with torque distribution normally configured at a 50/50-split front-to-rear. If wheel
Continuous All-Wheel Drive
speed differs between front and rear axles, the system helps distribute power to the wheels with the most traction.
Exclusive to WRX STI, Driver Controlled Center Differential (DCCD) All-Wheel Drive uses an electronically managed multi-plate transfer clutch
Driver Controlled Center and a mechanical limited-slip differential in conjunction with a planetary-gear-type center differential to control power distribution between
Differential (DCCD) the front and rear wheels. Featuring manual and three automatic modes, DCCD splits power 41% front and 59% rear. Sensors monitor
All-Wheel Drive parameters such as wheel slippage, steering angle, throttle position and braking to help determine torque distribution and direct it to the
wheels with optimum traction. DCCD also features a limited-slip helical front and Torsen® rear differential.
STABILITY AND TRACTION
VDC electronic stability control utilizes sensors which constantly monitor wheel speed, steering angle, brake pressure, vehicle yaw rate and lateral
Vehicle Dynamics Control (VDC) 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
Traction Control System (TCS)
engine torque to the slipping wheel or wheels as necessary to maintain vehicle motion.
