This is the distribution of real world drive ranges based on consumption between each fill up if I had run the tank from 100-0.
Biggest GOM I have had is 386km/239mi.
The average is 334km/207mi but we mostly do city driving. only dips down in winter and country road trips
Big advantage for us in AUS is that for most of the year we are at optimum battery operating temperature.
Here is the differ between what the GOM says and what we actually get. This is pretty much the Misses' work as she does most of the driving. I tend to pull the averages down with my lead foot on the weekends. Jan was outrbig country trip around the south west so lots of long drives on country roads at 110kmh
