How accurate is the MPG calculation on these cars?
As I understand it the car has a 65 lite (14 gallon imperial) tank and so to be getting 30mpg you would need to achieve 420 miles to the full tank. Is anyone getting anything near that??
Looking on fuelly there is pretty much no one getting above 20mpg out of 34 registered owners.
I have fallen into the trap of believing the lying b*stard computer myself thinking I was getting 32mpg on my current S5 till I did the maths and realised its actually 23mpg.
I am pretty keen on switching to a facelift ISF but dont want to drop any lower than my current 23mpg really
