nope, I did it in US MPGs as most people here are american. If you do the math, 7 l/100 is 34 MPG. I never understood why people have to be rude about things.

Not what the OP asked for but, my 335d has a record high of 36.04 mpg (downhill from Blacksburg Va to Trenton NJ @ cruise control 77 to 80 mph) and the record low is 29.89 (suburban Atlanta expressways with traffic). The average over the last 13 tanks is 32.66 (Road Trip iphone app). I've found that the brand of fuel used may make a bit of difference too. THe recod high was on Hess (but way downhill) with Exxon and Chevron close behind. Record low and generally low were Shell fill ups. Texaco also produced lower fuel milage. There are too many variables in my driving patterns to rely on this information as much more than random data points.

Mein Auto: X5d
I have heard/read great mileage claims since before I purchased my 2011 X5d (it was a consideration in the purchase) and am yet to see anything close to what a lot of people report. After 20K miles, I am consistently in the 18-20 range in the city and 25-27 on the highway. Am not an aggressive driver although I typically set the cruise control 7-10 MPH over the speed limit on the interstate. So I give, what is the secret to such great mileage (other than driving 60 MPH)?

my secret...slow on the acceleration...i try and keep my acceraltion to 30mph slow...i find if i do that, I add a tone of extra mileage. my wife doesn't and she takes a big hair cut on the milage. Plus, I don't use cruse. i work with gravity. if its a little up hill, i maintain ruffly the same consumption and will slow down, and on the downhill i'll pick up my speed. being a big car that isn't aerodynamic will also affects you. If i have a fat head wind, i'll keep it at 60...but if its normal wind, or a tail wind, anything up to about 70-73 mph will give you about a 32-34 mpg average. City, when I cruse, I'm either just holding my 5th gear at 30ish mph or just holding my 6th gear at about 45. this typically returns 45-49mpg. all that combined gives me a total life of car average of 30.5 mpg hope that helps

Most of people post very optimistic or wanna be numbers

My real world numbers after 2 years and 17k miles

Highway easy driving 70-75mph 29/30mpg
Highway ticket driving 85-90mph 26/27mpg
City normal driving 21/22mpg
New England winter city normal driving 18/19mpg

Panic, I think your numbers are more realistic.

I just don't see how folks are getting these 30+ mpg with an X5 when I'm barely getting 29 in my 335d. I do have a heavy foot though.

Purely highway or city FE does not interest me.
I only go by miles driven per tank which I log on Fuelly.

Our vehicles are meant to be driven for enjoyment rather than like a granny.
What's the point of buying a performance vehicle if you are scared to drive it like it's meant to be driven.
I've tried cruise control a couple of time initially but found it too boring and have not touch that again.

If FE is the main concern then a Prius or a Jetta/Passat TDI is the better choice.

Despite driving my vehicles hard most of the time I am pleased with the driving range of a diesel vehicle 'cos of it's better FE.

Just enjoy your X5, as no matter how you drive it, it's 30% more fuel efficient than the gas version.

I had on 2010 BMW X5 diesel a 24 mpg in city and 29-30 mpg on interstate with cruise control on. If you drive around 60-65 mph that increase mileage per gallon about 2-3 mi up. I confirm it on all cars diesel and gas engines, big SUV and small cars!

has anyone modded the exhaust systems, like taking the DEF ,DPF if there is one), resonator, muffler, and ecu mod so engine lights dont come on??

on my Chevy 6.6L ,removed all the exhaust system(came down as a complete assembly), went with 4" full length, MPG 3 more to a gallon US, much improved power and engine response, maybe the X535d can better the improvement!?

not turned up the fuel on it YET! so far NO smoke. i like the sound also.

Consistently get 28 mpg on the highway, with the occasional 29-30 mpg. Don't do enough city driving to get an accurate number, but it seems to be in the range of 19-23 mpg with short trips. I've noticed that short trips really impact the mpg of the diesel... much more than I've noticed with gasoline engines in the past.

It also drops a bit in the Winter, probably due to Winter formulation of diesel.
