Not available
Subaru Intelligent Drive (SI-DRIVE) enables three distinctively different modes of
vehicle performance characteristics by regulating the engine control unit (ECU) and
by fine-tuning the electronically controlled throttle.

SYMMETRICAL ALL-WHEEL DRIVE
Continuous 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
speed differs between front and rear axles, the system helps distribute power to the wheels with the most traction.
Driver Controlled Center
Differential (DCCD)
All-Wheel Drive
Exclusive to WRX STI, Driver Controlled Center Differential (DCCD) All-Wheel Drive uses an electronically managed multi-plate transfer clutch
and a mechanical limited-slip differential in conjunction with a planetary-gear-type center differential to control power distribution between
the front and rear wheels. Featuring manual and three automatic modes, DCCD splits power 41% front and 59% rear. Sensors monitor
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
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. Exclusive to WRX STI, VDC features Standard, Off and performance-oriented Traction modes.
Traction Control System (TCS)
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.
