[V8] Quattro vs Haldex

[urq]

A standard open diff has a 50:50 torque split, a welded diff isn't really a
diff any more ... and it can send 0 to 100% of the torque to either output,
and any torque build up due to the difference in track length between the
two outputs has to be dissipated via tire scrub.

That predictability factor of Audi makes sense to me and by welding the diff

I guess they are splitting the torque 50/50?   Fuel efficiency is not such a

concern racing, but then in the real world it's huge now.
