Managed to get a fuel consumption of 5,1 l/100 km (according to the journey computer) on a approx. 1000km journey, including some stops, a lot of 70km/h and 80km/h speed limit zones, and some 100km/h motor way zones. Average speed: 70 km/h. Almost all the 100km/h zones were done with cruise control active. PS: all driving was done in Sport mode.
I'm sure I could get it lower (at least under 5,0) but didn't drive with fuel saving in mind all the time.

Drove from Stavanger and almost to Oslo and back to Stavanger again, around the south coast of Norway.

Have also done som real life consumption calculations (checked the gas receipt against the mile coverage on the tank), and it seems like real life consumption is always 0,2 l/100km higher than the journey computer says.

The computer in the middle of the dials says:
Avg. overall fuel consumption after 27500km distance covered: 7,1 l/100km. 70% city driving.
