Hi Peter:

Our conversation got me really curious and so I decided to poke around a bi=
t=2E The most detailed information is in German and after reading about 10 =
webpages and speaking with Mr. Kluge here is the final word on Torsens:

ALL Torsens split the torque 50/50 all the time. There is no difference her=
e=2E

There are only 2 Euro versions of the Torsen: 01E 409 751 and 751E. The dif=
ference is in the MAXIMUM torque split under conditions where the Torsen ha=
s to divide the torque (read: wheel slippage).

The 751 splits the torque up to 80% to one axle. It is installed in ALL V8 =
transmissions and the CRB.

The 751E splits the torque up to 75% to one axle and is installed in all ot=
her Quattro transmissions, even the new TDI ones and the S2.

The reason Audi changed the torque split for later models was twofold: one =
to prevent too much torque from going to one axle and causing damage. The h=
igher torque split also has more torque shock under those conditions with a=
ll 4 wheels spinning and so Audi lowered the torque split to keep the peak =
torque load and resulting shock within limits.

The average driver won't notice the difference.

Hope this helps.

Kind Regards

Rob
