Those whoe think that Audi's Quattro is superior, have you ever tracked your Quattros??? Audi's quattro is known for its understeer specially in tracking conditions, but it's fixed with the new R8 ,which transfers more power to the front wheels only after the back is loose, unlike the older version when the cars didnt allow oversteer.
EDIT: Lets put it this way, EVO X AWD system > BMW Xdrive > Audi Quattro .
