I've been browsing around on www.patentstorm.us searching for patents filed by "Fuji Jukogyo Kabushiki Kaisha" (aka Fuji Heavy Industries, parent company of Subaru) around the time that the SVX was being developed, approx 1988-91.

Many of them come from other branches of FYI, relating to trucks, trains, aircraft etc. But there are some that seem to relate specifically to the SVX.

One that particularly caught my attention is 5018594 "Rear-wheel steering system for four-wheel steering vehicle". I reckon this provides probably the best description we will ever find in english for how the 4WS works on the version L.

There are several relating to the specific parts of the engine and AWD system and even some relating to "active suspension" and the "anti-frost windscreen" that were supposedly seen on the SVX concept car.

Interesting stuff, if only they were a little easier to comprehend.
