Miles per gallon?
 

I've had my '09 Cayenne turbo s for a couple years now and I'm getting antsy. With a number of other M cars in the stable and being disgusted with how Porsche charges, an X5M is looking pretty good.
But, I'm reading about real life reports of 9 miles per gallon. My Cayenne's averaging 14 to 16. It isn't about the fuel cost, just inconvenience and the principle. Is that really what you guys are getting?
Thanks for the info!

I regularly get about 15 mpg.
I do a fair amount of 80mph highway driving. Without that, 13 would not surprise me. It is a very heavy vehicle. Wish they had made a bigger gas tank. I'd rather get 12 mpg but get 350 miles between stops versus 15 mpg but have to stop 100 miles earlier.
I never mind the fill ups however. The X5M is a pleasure to drive and super practical.

14mpg with a nice mix of city and highway. I feel, I don't get to open it up enough though.

90% of time i think im pretending i am going around the Nürburgring so i avg.12.5 mpg

Over 12,000 i've averaged 13.4 miles with about 60% city 40% highway but a lot of stop and go highway. On pure highway miles at about 75 mph I can get 20 mpg. It really is not much worse than my 2008 4.8 and about the same as my Cayenne GTS. Well worth the cost now but gas is cheap....

Mswaz:
Do you keep in in M and Sport mode or vary it?
My understanding is that Normal mode gives the best mileage, M mode reduces it slightly and Sport mode reduces it a good chunk.

I look more at smiles per gallon. I get 4 smiles per gallon and around 14 miles per gallon.

I mainly keep it in normal with spurts of M mode with sport shifting. Cloverleaf freeway on ramps are the best.

My average is 11 but I really wouldn't care if I got less, the driving experience is absolutely worth it.
