Gentlemen I have taken these lines from Wikipedia "In Japan, the 3-door series started with an R in the series ranging from RZ, RX, RS to RJ while the 5-door line-up started with T in the series ranging from TZ, TX, TS, to TJ. All models came with front double wishbone and 4 linked suspension as well as full-time 4WD.". My question is that what does full time 4WD mean? Does it mean even for normal running on black top roads it would have four wheels powered or something else which I,ve failed to register. I know a Corolla car model which is all time 4WD but heavy on consumption. Please excuse my ignorance if I,ve posted the question at a wrong thread.
