If wheel speed differs between front and rear axles, the system helps distribute power to the wheels with the most traction. WRX models feature a viscous-type limited-slip rear differential. Active All-Wheel Drive 2.5i and Outback Sport 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 distribution and direct it to the wheels with optimum traction. Variable Torque Distribution (VTD) All-Wheel Drive WRX models, equipped with 4-speed automatic transmission utilize an electronically controlled variable transfer clutch in conjunction with a planetary-type center differential. Torque distribution is normally configured at a performance-oriented rear-wheel-biased 45/55 split frontto-rear. Sensors monitor parameters such as wheel slippage, throttle position and braking to help determine torque distribution and direct it to the wheels with optimum traction. WRX models feature a viscous-type limited-slip rear differential. Driver Controlled Center Differential (DCCD) All-Wheel Drive Exclusive to the WRX STI, Driver Controlled Center Differential (DCCD) All-Wheel Drive, featuring both manual and automatic modes, uses an electronically managed multiplate 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. Normally, 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 helical-type limited-slip front differential and mechanical limited-slip rear differential. CHASSIS Steering Engine-speed-sensing variable power-assisted rack-and-pinion.
