All versions of the SVX sold were equipped with automatic transmissions. Depending on the country, Subaru had two versions of their All-Wheel-Drive system for the automatic transmission, called ACT-4 or VTD. The first system, called ACT-4 (Active Torque Split) by Subaru, was the same setup commonly found on other Subaru models of the period, and used a variable clutch pack center differential using a 90% / 10% power split front to rear, which could transfer up to a 50% / 50% power split for maximum traction if the front wheels started to slip, allowing better fuel economy. This AWD system was offered throughout the entire production run, and was used in vehicles manufactured for sale in the USA, Canada, Germany, France and Switzerland. A sportier continuous traction delivery system, called VTD (Variable Torque Distribution) by Subaru, was used in vehicles for sale in Japan, England, the Benelux region of Northern Europe, Australia, Spain, Austria and Brazil. The VTD AWD system is a permanent AWD due to its 36% / 64% split. (Source: http://www.wikipedia.org )

2008 WRX STi is equipped with multi-mode VDC. Normally, the VDC button simply turned the stability control system on and off. Multi-mode VDC offers drivers three different combinations of stability control, traction control and ABS performance to suit any driving condition or driving style.

Full-time all wheel drive with 41/59 torque split front-to-rear under normal conditions. Driver-controllable Center Differential System (DCCD). A limited-slip, planetary gear-type center differential, augmented by an electronically controlled center limited-slip differential, provides a performance-oriented 41:59 torque split. The mechanical limited slip differential has a quicker response and activates just prior to the electronic limited-slip differential. In any of the three automatic modes, the electronically managed continuously variable transfer clutch can vary the distribution ratio through the center differential as needed to suit driving and road-surface conditions. The DCCD AWD System has three automatic modes in the 2009 WRX STI: “Auto” is the same as in the previous-generation model. The new “Auto (-) Active Sport setting shifts the torque bias to the rear and also opens the center limited-slip differential (no locking factor), which improves steering feel. For driving on slippery surfaces, such as gravel or snow, the Auto (+) setting tightens the LSD. In manual mode, which offers six driver-selectable settings, DCCD allows the driver to vary the front-to-rear torque distribution to optimize All-Wheel Drive performance to suit specific driving conditions.

“Helical-type” front differential (2004-... WRX STI), varies the torque delivered to the left and right axle shafts, depending on traction and engine load. Instead of locking the output shafts so that they rotate at the same speed, this differential sends more torque to the wheel with more grip. In addition, it makes a gradual adjustment for a more fluid response.

Some vehicles are equipped with Vehicle Dynamics Control (VDC). VDC operates like most electronic stability control (ESC) systems. It can adjust engine output and adjust individual brake pressure. Any vehicle, with MT, 4AT, or 5AT transmission can have VDC. On vehicles with automatic transmissions, to retain/regain vehicle stability VDC tries to adjust the front/rear torque split to balance the available traction, rather than applying brake force. If the total traction is still not enough for stability and wheels continue to spin, the system will then use braking and reduced engine power to reduce momentum and help regain control.

Full-time all wheel drive with 45/55 torque split front-to-rear under normal conditions. Electronically controlled hydraulic multi-plate clutch installed in conjunction with the center planetary-type differential. Sensors monitor parameters such as wheel slippage, throttle position and braking to help determine the amount of clutch lock. Optional viscous-type limited-slip rear differential.

Proactive automatic all wheel drive with 60/40 torque split front-to-rear under normal conditions. Electronically controlled hydraulic multi-plate transfer clutch installed instead of the center differential in the transaxle's tailshaft. Sensors monitor parameters such as wheel slippage, throttle position and braking, to help determine needed torque distribution to the rear axle before the wheels start to slip.

Proactive automatic all wheel drive with 90/10 torque split front-to-rear under normal conditions (80/20 from 1996; 60/40 on Subaru Forester from 2009 and on - Source ). Electronically controlled hydraulic multi-plate transfer clutch installed instead of the center differential in the transaxle's tailshaft. Sensors monitor parameters such as wheel slippage, throttle position and braking, to help determine needed torque distribution to the rear axle.

Full-time all wheel drive with 50/50 torque split front-to-rear under normal conditions. Viscous coupling locking differential in the center inside the transaxle case, activates when wheels start to slip. Torque apportion from 80/20 tro 20/80 ( source , because the coupling can't be locked completely?).
