the differential is a very simple, well understood and well documented
mechanical device. audi's quattro system is also simple to understand
and relatively well documented, but unfortunately the american press
has in countless occasions flaunted their stupidity on the subject.
(i sometimes wonder why people recognize the shortcomings of american
cars and go on to buy foreign products while they steadfastly stick
to low standards of american automotive journalism)
a conventional differential such as those used in the mk1 quattros has
absolutely no capability of sending power to the axle with more grip,
(while unlocked) neither does it have any ability to "sense" anything.
it is just a dumb device made up of maybe 4 or 5 major components in
the way a mk1 quattro behaves cannot be attributed entirely to its
center differential. it is the total combination of drivetrain,
weight distribution, suspension geometry and setup. a fwd car can be
coaxed to kick its tail out and we know that there is no drive going
to the rears.
i am quite surprised that there is even an argument emerging about how
the quattro system works. after all this is documented even in the
owner's manual of the cars.
