All my previous 7's I got about 270-290 miles per tank. With my new 2009 750i, I am barely getting 200-220miles per tank. Just wondering what you guys are averaging. Thanks!!

Oh my. I have a feeling that jerky start off the line is the result of a lot of fuel being pushed into the engine. I certainly noticed the quick to run engine that is probably going to affect fuel economy until you get the hang of the accelerator. 200 miles? Man, I hope this is an error.

The '09s have a smaller tank - by 1.6 gallons I believe.

2008 750 - 23.3
2009 750 - 21.7

Hmmmm gas milage seems lower but with a 90-110K car that wouldn't be my primary concern.

21.7 is darn good mileage considering the size of the car. My LS460L averaged 19.7, which I was very happy with.

Those numbers were the size of the tank. Sorry I was not clear.

yes gas mileage is not the concern. just want to make sure nothing wrong with the car.

yes of course, heavy foot will drastically reduce gas mileage. 240miles/tank I guess is normal since the tank is 10% smaller. Hmmm

my 740Li returns only 3.9kms per liter :( though its only 2 days old with 100kms on the odo.

Mine varies. In Sports+ mode for my everyday commute I average 15.4mpg. On a road trip in Comfort mode I average 22.3mpg.

All of the below was with a mix of city/highway driving, and mostly in "Sport".

First tank was awful - 225 miles
Second tank - 260 miles
Third tank (in progress now) - looks like it will be around 300 miles

Hopefully it will continue to improve :)

Do people see a difference in mileage between normal/sport/sport+?

Ah...thanks for posting. Now I feel better! I thought something wrong with my car. 260 miles/tank sounds about right. That is the most I ever got. I know I am a bit more aggressive. I could only dream to get 350 but then no more jack rabbit starts off the line:cry: .

yeah - even driving 'enthusiastically', i'd expect better than 225 on a tank if it stayed at that level, the m5 would start looking pretty good :)

yes you are right on...b/c 225 is like 10mpg which makes no sense at all. Keep us posted on your results. I am curious if this car is capable of getting 300/tank. I tried to change my driving habits but to no avail:cry: .

So here's my rather unscientific experiment:

- Last night I measured the gas mileage on my trip home. 25 miles door to door, mostly freeway driving, traffic was moving reasonably well, 750 in 'sport' mode, but drove in a rather "controlled" fashion (no rapid starts/stops, limited the rapid acceleration). Got home and the on-board computer read 18.8 MPG

- I repeated the experiment tonight, but kept the car in 'normal'. Surprisingly (LA freeways) the traffic was roughly the same, and I used a comparable driving style. Same route home. Got home and the on-board computer read 21.9 MPG.

I'm not sure if this really means anything.

I'm going to experiment with the suspension settings - drive on 'sport' for an entire tank, drive on 'normal' for an entire tank, and drive the way I normally would on both (meaning more aggressively :thumbup:) - figure it'll be interesting to see the results...

i'm now on my second tank since getting the car (2009 750Li), and i've slowly increased my average per on-board computer to 16.1mpg - always in 'comfort', trying to drive very smooth without any quick accelerations and including the trip home to LA from santa barbara. i'm rather surprised to say the least. i was in germany in november and rented a 740 diesel for nine days and averaged 22mpg - with a lot of city driving and autobahn sessions at high speeds. it's a crime for bmw to not offer the 5 and 7 as diesel versions in the US and instead opt for the hugely expensive hybrid with an even smaller trunk making any buyer the inevitable guinea pig. i'd like to know how many 7's are sold in the US to calculate the potential savings for a single production year - just in fuel.
curious to get your thoughts on a 7d, if you'd consider it.

I did the experiment I noted above on multiple tanks of gas -- ran the car on 'normal' exclusively or on 'sport' exclusively. About 65% highway, 35% city. Overall I'm not seeing a huge difference in mileage - close to 15MPG on 'normal', almost 16MPG when on 'sport'. Not great on either... (though I was getting a combined 19 in my '08 550i, guess I shouldn't expect the same mileage in a heavier car)

i've been getting a poor 14.2 with an ave speed of 29.5 mil. Pretty poor especially with a smaller tank on my 2010 Lix.

I concur with this post with the first tank being low mileage. My second tank averaged 14mpg in mainly city driving.

However I think the reason for the poor mileage from the first tank is 1) the dealership never fills the tank to max capacity and 2) they use regular not premium.

When I took delivery of my 2009 750LI 2 weeks ago I asked what is the minimum grade of fuel I should use? the SA told me that when the dealership hands the car over its always regular. However, the user manual states that the absolute minimum grade you can use is 89.

Well, based on driving the car for about 3 months now, if you're getting 14mpg in city driving, consider yourself lucky. When I'm doing mostly city driving, I'm getting closer to 10 (and I really don't think I'm driving the car THAT hard :). Maybe it's all the stop-and-go around Santa Monica - but I was expecting somewhat better (like I said in an earlier post - I'm thinking I could have gone with an M5)

I just refueled my third time. The tank was only half empty it took another 11 gallons to fill to the max, I had only done 107 miles. The on board computer stated that I had averaged 12 mpg but the hand held calculator states 9.7mpg. I am not that disappointed as my previous car FX35 only averaged about 10mpf in city driving. After all its a 4.4 liter V8

My second refuel averaged, according to the computer, 14 mpg


Moral of the story...don't rely on the on board comp....

To reduce the overall capacity of the fuel tank makes no sense. This is a full size luxury car and it should be able to go the distance.

ESPECIALLY in light of the fact that they've eliminated the spare tire well- they should have INCREASED the fuel tank size! I can only imagine that they've saved millions by eliminating the spare and jack on our cars.

Just to throw in my .02 worth. I'm averaging 25mpg in the city and 29-30mpg hwy in my activehybrid7. And that's with a not-so-light pedal. I am pretty amazed so far. Getting around 450-500 miles per tank before my reminder fuel "DING"

That's pretty awesome. I average just over 17 mpg in mixed driving in my 750i.

25mpg in the city compared to my 10mpg in the city and 17mpg on a recent run to Atlantic city.. I wanna a Hybrid!!!

Have 2400 miles on my new 2011. Before i talk MPG just let me tell u that this car is a masterpiece - and this from a guy who's owned four 7-series.

Ok. MPG. My 2004 745Li would get 15.9MPG consistently. My 2011 is getting 13.5 MPG. Why do i care when i can afford a $111K car? Range! I used to fill up my 2004 every 14 days, this thing is every 8-10 days. MPG is lower AND gas tank size is lower. Getting 250 miles of range. And that is OUT of sport mode.

Dealer told me that it does improve as the engine "loosens up" which could take as long as 8,000 miles. I hope so, kind of a pain. Heaven help someone that gets the 550 - same engine with 18 gallon tank! Even with it being lighter i'd be filling up every 6 or 7 days.

Still doesn't make not love this astounding vehicle.

I know you have mentioned this before and I was wondering after I posted have you tried resetting the counter while your driving at highway speed, say 70-75 MPH and if so is it still reading that low? I cannot imagine how hard you would have to push the car to average that low. Recently the roads around here have been clearing up and I have intentionally pushed my B7 much harder and have pushed my average down to 17 mpg, mind you I have about 75% of my daily drive on uncongested interstate highway.

To average 10 there must be a lot of 5-6 mpg coupled with 13-14.

dbs600: I think that 10 mpg is definitely possible if you do a majority of your driving in the city. I drive to and from work everyday in Chicago city driving but I have taken a few long drives (about half the time), which brings my average to around 14 mpg. So, if we assume that I get an average of 22 mpg on the highway 50% of the time to get to my average of 14 mpg, then it must be that I average 6 mpg in city driving 50% of the time. However, had I not taken those long drives I am pretty sure my consumption would be around 10 mpg. Supposed if I apply the 6 mpg city and 22 mpg highway and changed the percentages to 80% city and 20% highway, I would have been looking at an average of 9.2 mpg. Note that those numbers are with a smaller engine (my 3.0 I6 vs your 4.4 V8), so it is definitely much possible to get lower mpg numbers in your vehicle.

I haven't calculated my mileage yet because it's still the break-in period for my car. However, with driving primarily in Sport Mode, I seem to be doing much better gas mileage-wise than my previous M6 and that's a good thing!

So I have 2,900 miles on the clock and I'm still getting sub 10 MPG's. I've yet to discuss same with my dealer, as I've focused on my steering and transmission woes - so they do not have opportunity / reason to confuse / relate supposed driving habit with same. Does anyone have any idea what could be causing such bad numbers!?

Yikes...sub 10 MPGs!!! That's not good. Is your driving mostly in-city (stop and go)?

03-21-2011, 05:14 PM
as I'm approach the 1st thousand miles, I can't get more then 16.5mpg. that is mix of city/highway, with very light foot on the gas too ! guess, that is the price when you get 8cyl !

Coming from a 2004 745i to a 2011 750i has been a mileage shock. I thought that the lighter engine and improved engineering was supposed to confer a mileage improvement or, at the last, keep it the same, but I went from an average 19 mpg with the 2004 to barely 16 with my 2011. Could it be the twin turbo chewing more gas? Dunno... It does seem harder to keep the horsies in the 2011 confined to the speed limit corral, I must admit..

Cruse active @ 83mph or 77mph, on board calculation typically 22.4-22.9 MPG from the computer, premium Shell.
Around town or local highway 17-20 MPG non active cruse.

Im getting just over 400miles out of a tank (varied driving city/hwy). I use sport mode a lot and generally use the engine through all its ranges. Not too soft, but only use the kick when needed. Im using the 740iL with the 3.0 TT and while I was a little concerned leaving a 2007 750i, this baby has way more torque, better driving characteristics, and runs about 5mpg better overall. The 6 is more than enough car for me - I can save the rest for the track!

Mixed city/highway:
2003 745i 16-17mpg.
2006 750Li 16mpg.
2011 750Li 14mpg (only 2K miles so far).
Call me environmentally unfriendly, but I don't really care about the mileage since I don't put a ton of miles on the car.
However, I do miss the larger tank :(
