Road trip NC -> NJ, with some around town driving before I left, and spanning 3 days.
Still had 15 miles remaining on the trip computer, and another 20 miles or so past that, so could have gotten close to 650 if I really tried to push it. Confirmed also by "only" filling with 18.8 gallons.
Highway cruising speed around 78mph when possible.
15k miles on TDI now.
Zoomed in for just the Q5 TDI. Prior best was 31.7mpg:
I'm now running the VAGCOM fuel consumption accuracy at "107" to see how that does. 106 was clearly still too optimistic, but we'll see how 107 vs 108 compares after a few more tanks.
609 miles is new best. Previously it was 604:
"only" 18.8 gallons to fill up for these 609 miles:
Still driving the TDI a lot (and thinking about selling the 996TT):
