My brother-in-law mentioned to me once that his truck would stop quicker in
the snow if he had the 4WD engaged [no ABS] and I thought he was nuts, it
just didn't add up. But then I bought and drove a 4WD truck in the snow, and
I now know it to be true. Don't ask me to explain it, and other people may
think I'm nuts [spider bite anyone?], but if I needed to stop fast in snow, I
would throw it into 4WD and pump the brakes, and the truck would seem to grab
better. So maybe Quattro does help to reduce braking distances in the wet
stuff [rain or snow]. Don't knock it til you try it. I can't wait to get my
hands on a Quattro equipped Audi and give it a try, for now my fwd with ABS
will have to do.
