Interesting thought.  The Torsen-equipped ur-quattro has a longtitudinal
accelerometer in the ABS system.  However, the "Torsen-equipped
ur-quattro" has quite a few things that the non-Torsen car has not.

Is the accelerometer just a "running improvement", or is it associated
with the adoption of the centre Torsen?  Do late-model cars without
centre Torsens still have accelerometers?
