"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.[4] The Japanese-spec SVX was equipped with four-wheel steering (4WS).

Subaru began to realize that the high selling price of the SVX was giving some buyers "sticker shock". In an attempt to attract more buyers, a Front Wheel Drive FWD version was offered on the SVX during the 1994-1995 model year, which cost about $1500.00 less than the AWD version. In 1994, FWD was offered on both the L model (X33 in the VIN) and on the LS model (X34 in the VIN). In 1995, only the L model was offered in FWD (X33 in the 5th, 6th and 7th digits of the VIN). Buyers avoided the compromised FWD version and weak sales figures led to its discontinuation after 1995."
