Fuel consumption on X3

[Afc69]

Hi, just taken delivery on a new X3 and what a delight, cannot fault it.

Apart from from fuel consumption. It’s a petrol model so I wasn’t expecting 40mpg but I did expect over 28, as that’s what getting. I do mostly town driving with the odd country drive but is 28mpg what you’d expect in that scenario?

Done 1500 miles, will the mpg improve over time?

Should I use Eco mode to improve mpg?

Short journeys were it cools down before you drive again and has to warm up every time will really hurt mpg and stop/go town driving will do the same .That said the figures claimed now are impossible to achieve as they were probably calculated on a rolling road and also on the narrowest wheel/tyre options I suspect and wider wheels cause more drag . My x5 e70 claimed 34 mpg but in the carefullest of driving I seen 30 only once in a year , the narrowest tyres were 255 all round but I had 285 front / 325's rear tyre on so this won't help .
The only thing will improve it is a very careful driving style trying to brake as little as possible by anticipating the road ahead which will get quite boring very soon !!!!!!!

Just enjoy it and don't worry too much about the fuel bill, you should try running a 4.6 economically, lol.

Ours averages 33.9mpg (UK gallons), mostly.short around town journeys. On longer journeys it usually in the high 40s, once it was over 50. This is 2.0l petrol.

I was the first on here to post regards the G01 X3 2 years ago now
So far 35,000 klms done...20D X3 G01 From new Feb 2018 ….6.7 litres to 100 klms or 42.16 mpg overall
Almost identical to the Lexus 220D 2.2 I had before this BMW...being a larger heavier vehicle I class this as really good for the SUV.
