Re: Audi Kool-Aid, Pt. II (long)



Matt you are a brave man!!!!!!!!!!!!
As a fellow lister who regularly got flamed (less lately, with the exception
of 1 or 2 very UNDISGUISED listers), I can relate to your bravery making
this point.
I do remember Scott (of Q ship) making a similar statement a while back (yes
as far as I know, Scott is still alive).

Now comes my point:
in the hands of an average +- every day driver, a Q will perform BETTER than
a car not equipped with AWD.....(most of us fit in this category)....
in a racing condition (none stock, high power) the article agrees that the
AWD is superior due it its ability to deliver power via 4 wheels.....

Your thoughts.....

the

a

>times:  q 39.9, fwd 40.1.  Wet lateral G was .70 for the q and .69 for fwd.
