At the end of my holidays I have some (not-so-precise) measurements, and I found it quite interesting. No surprisingly the best mpg is measured around 90-100 km/h (around 60mph). At lower speed the engine did not like to pull the car with the 6th gear. What was surprising to me though is that at 150-160km/h consumed just as much as at 120-130km/h. Actually at the higher speed it was better in terms of going uphill and could less press the pedal downhill. Also figured out that with right foot can save more than with cruise control. I think this was mentioned already. The reason is that if you allo= w the car slow down uphill and accelerate downhill then it takes less than just keeping the same speed all the time. What I was thinking if that is possible to write a firmware to save fuel based on intelligent acceleration= ? Anyway, at 110km/h I could achieve around 6 l/100km (47 uk-mpg) while at 150km/h was around 8 l/100km (35 uk-mpg) which is also not that bad in my opinion.
