I think it is because I do 90% highway and back road driving at speed that helps. I have gotten almost 400 miles on a tank on a long trip so I think my computer is working. I do not do much if any stop and go or city driving. Of course the faster you drive it the more gas it uses. But I bet city driving really drives down milage.....Steve

those are both too high. 12.5 is a solid avg' driving "hard"ish..

I'd say having the ///M for only the cost of the fuel is pretty lucky :zoom:

I mean I get close to 20l in my 325xi because its a fatty, I'd say profit from the HP and just enjoy it!

I guess you could try D instead of DS. :thumbup:

12ish as a average seems about right. Awesome drive. I'm going to cry when I have to give it back.

You are 100% right. It was just a bit of a shock after my E53 3.0d ... seems to use about twice the fuel and premium petrol costs an arm and a leg here.

I don't think my X5M would get 20mpg if i threw it off a cliff. And I don't care.

my consumption over the 6500k's I've driven mine (X6M) is 16.5L/100. they weigh the same as X5M's though

~3000k's of that was driving to townsville and back from brisbane, over which I avg'd 11.5L/100 - the rest is strictly suburban driving. using the second tripmeter I read around 18L/100 for the last few tanks

I went fairly easy on the pedal for the townsville trip, just to see how well it would do on the juice. driving around town though is a mix of easy driving until it's warm and then all bets are off

so 20+L/100 seems high from my perspective

I get about 14 with a mixture of steady highway and aggressive city driving.
For the weight of the car and how it doesn't show it.....I am amazed that it's not 10!

20 seems quite high, must have been very heavy with the fun pedal? My dealer also gave me an x6m loaner for a few days. It was apparently the first one in the country so they were treating the car like a baby, even delivering it to me on a flat bed truck!!

I managed to get 14L/100km. This was with mixed driving. Didn't really push it too hard as car had less than 500km on it. So i was actually quite impressed by the fuel consumption given what's under the hood.
