well actually, that is the normal quattro diff assembly mike.
i understand that audi have invested a lot of time and dollars in low friction diffs
which minimise the frictional losses that awd cars have (2 extra diffs) over the fwd
and rwd ones.
remember that in fia class 2 where you have engine capacity limits
*and* rev limits, this severely limits the potential hp gains your engine might gain
over the opposition, and means that the premium is in minimising all frictional losses.
i was amazed to find the absolute science that went into oil pumps and scavengers
with a view to minimising engine frictional losses....
