[urq] "new" AWD systems (was: Mark Komanecky?)

[Brandon Rogers]

I don't know.  I'm not so sure about the open diffs.  Sure we can lock them 
but I like the _idea_ of the variable torque split....locked diffs are great 
on snow and ice, but I would guess variable is too.  My A4 is probably 
better in the snow than my urq - around town at least when I gun it around 
corners and such - it seems to hook up better....part of me wished I put the 
200 20V tranny in the urq when I did the swap...just to see the 
difference....

.....uh oh should we move this to the Torsen List???  ha ha
