TORSEN's in racing?

[Joe Yakubik <75363.2524@compuserve.com>]

Either Eric F. or Scott (PDQSHIP) wrote that TORSEN's weren't used in racing.
What did the A4Q's in the DTM and the BTCC use?  

Phil, you were in the car, did you ask?  Thompson (are you out there?) you've
got the photo montage breakdown, does it say what kind of diff in the text?
Anyone else with a spec sheet, or does it just say "quattro system"?

I've got the '91 200qw  w/ TORSEN and have experienced primarily understeer.
Never too intrusive, easy enough to control, both with power on and off, varying
road surfaces and conditions.  I wouldn't exactly call the wagon balanced
though....
