Hi/ I have owned 3 Q5s, & am now waiting on my first A6.(With 75 litre tank). Still donât have a build week L Can any existing A6 owner tell me:- How accurate was the prediction of range? On the Q5 it is worse than useless. I will fill up at Calais. It will predict a range of 970km. My driving style doesnât change. â That is the actual consumption has been, & remains constant. To reach the Dordogne, I should have a reserve of some 100km. I actually struggle to make it on the tankful. So? Are A6s better?
