its for the theorical range. in last gear and in maximum engine rev the car can do 260 therotically because of the gear ratios. but in real life this car cant reach that speeds. my car has a very high number on speedo to but i barely reach 60kmh per hour in my daily commute lol
Keep in mind that it goes with the accelerator fully open at more than 200 km/h, it is normal that it shows those consumptions, I have seen diesel engines consume more than that.
