cmon people you can do better.. I remember doing 73-74mpg on my old 2003 1.2 jazz in good summer weather while sticking to a bit under 90km/h speed limit pretty much everyday while going to work and pretty much gliding in neutral through cities/speed zones without touching the accelerator/brakes ,also No hills whatsoever down where I was.
If I reduced the speed to 70km/h while in some looooooooooooong ass german roadworks I remember getting 80mpg
