Well, I drove to the next town west of here for lunch, 145 km each way. It's hilly and lots of passing required with speeds mostly between 80 and 110 kph.
My previous two trips in the stock GV yielded 7.31 and 7.29 L/100km.
With my shiny new free-wheeling hubs I netted 7.04 L/100km, a 3.6% improvement.
The only variable that I can't confirm is the same is that I may have used the AC occasionally in the first two trips, while I did not use it today.

I tried to avoid too much heavy use of the accelerator, but still was well and truly out the front of the traffic (so not being ridiculous and trying for the best figures possible.) That's outer city driving too with mostly 17km trips to and from work.
Not as much use of the A/C now as the weather is cooling down.
