SYMMETRICAL ALL-WHEEL DRIVE
Continuous All-Wheel Drive WRX models equipped with 5-speed manual transmission utilize a viscous-type locking center differential with torque distribution normally
configured at a 50/50-split front-to-rear. If wheel speed differs between front and rear axles, the system helps distribute power to the
wheels with the most traction.
Active All-Wheel Drive WRX models equipped with 4-speed automatic transmission utilize an electronically controlled variable transfer clutch to distribute power to
where traction is needed. Sensors monitor parameters such as wheel slippage, throttle position and braking, to help determine torque distribu-
tion and direct it to the wheels with optimum traction.
STABILITY AND TRACTION
Vehicle Dynamics Control (VDC) 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.
Traction Control System (TCS) VDC also incorporates an all-wheel, all-speed traction control system which senses a loss of traction and applies braking force to the slipping
wheel or wheels as necessary to maintain vehicle motion.
