Cool, I guess when I did 700 miles on a single tank of fuel driving Switzerland to Italy and then again driving Italy to Austria and then again Austria to Netherlands this summer I just imagined it. My total for the 3000 miles was 38mpg(imperial).

Also you are quoting a value for the B5, which is not what I have, mine is a T8(and before you ask - no, I didn't have any opportunity to charge it anywhere on the way).
