Great review and content as always.. I've always prefer Audi over BMW or Merc, but definitely it's not as popular in Malaysia.. And this more or less impact consumer decision mainly on typical aspects like parts and resell value..
The comments on this quattro dont really so the system justice. Its 4wd by default not fwd. It only disables the rear drive when not needed e.g. cruising in a dry motorway. It can react and go 4wd but it also predicts and is proactive using the cameras to look ahead and the satnav to know bends are coming etc.
