Can somebody link me to a page that describes how the quattro system works in this vintage of A4?
As I understand it, this year of the car of course uses the torsen but there is no locking differential at this point; any wheel slip that makes it's way through the torsen is counteracted by braking at a wheel? Were they also incorporating any kind of throttle control at this time (i.e. if wheel slips, throttle is backed off) or did that not get implemented until the drive-by-wire throttle was installed?
And what's the story with the ESP? When was usage of that system begun? Best I know, that's not included no my vehicle.
I'm all the more curious these days as I recently had my first snow driving. The car generally felt much more stable or maybe I'd say "dumbed down." It was very difficult to get any wheel-spin in the snow, but tracking was good on and off the throttle and brakes. Just trying figure out what exactly is going on where the rubber meets the road.
