showing 980km when you refilled and even with topspeed ending up with about 700+ km in range you start thinking if you really need a more powerful car. Even the acceleration and topspeed is absolutely OK, the chassis makes fun enough for all kind of needs. The appearance of the interior is a little better than MB and BMW, but therefore the leather is more vulnerable to liquids and dirt. As a fan of rearwheel-drive I would choose BMW and I even like the iDrive more than Audis Entertainment-system, but there is no way to say the one car is better than the other. And anyway you do not race an Avant or Touring through curves as you would do with a M5 or RS6 sedan... The 2,7TDI is a real great choice!
