The G01 X3 30i's EPA numbers are 22 MPG City and 29 MPG Highway. My F10 535i's EPA numbers are 20 MPG City and 30 MPG Highway. My worst tank was 19.7 MPG in ubran/suburban driving. My best was 30.7 MPG, pure highway, 72 MPH, AC on, with a good tail wind.

You didn't say how many miles you have on the car. Fuel economy will improve after it gets broken in. It can take up to 10k miles for an engine to get fully broken in. Also, there are varying degrees of urban driving. Cars burn more gas before they're warmed up, too. When I mope down to the shopping mall two miles from my house, I'm in the mid-teens on MPG.

 

Thanks for the info! I currently have 2,600 miles on my x3

 

I'm glad you raised this thread - I was particularly interested in M40i real world.

I know most car manufacturers quote ridiculous controlled figures, which is not so bad as you could do comparative analysis - but I found in the past the delta from their figures to real world is vastly different. E.g. I had a Merc 220d 10 years back that quoted 55, I got 40. This bloody 35d now quoted about 54 ish and I get 32. Go figure.

Anyhow - back to the plot - M40i real world would be nice.

 

The US EPA adjusted their fuel economy testing and calculation methods for the 2008 model year, resulting in lower and more realistic numbers.

Fuel economy depends a lot on the driver. Frau Putzer says I drive like an old man. I am an old man, but my driving is the result of pursuing efficiency, not senility. A few years ago she had a Prius rental car. She was getting MPG in the low 40's. When I drove it, I could hit 50 MPG. ... in U.S. gallons.

I plan my stops. My philosophy is that braking is the result of either bad luck or bad planning. If I see a line of cars at an upcoming red light, I throw the car in neutral (I have a manual transmission) and start coasting. In addition to saving fuel, I also save brake pads and rotors. My previous BMW had the original brakes when I sold it at 115k miles. My current BMW is heavier and has smaller brakes. Based on the remaining life display, I should get somewhere between 90k and 100k miles out of the front pads.

Except when succumbing to my love of acceleration, I shift at just below 2000 RPM.

 

I get about 14mpg average. I do about 90% city driving 10% highway. Guess you can say i have a heavy foot and the car never leaves sport mode....:rofl:

Mostly commute to and from work, about 12 miles so its difficult to gauge all around.
600miles in.... sport mode really keeps lower gears readily available.

 

I am getting a average of 22.4 MPG on 60% highway and 40% city with ASS turned off.

 

So far I'm getting about 18.8-19.1 mpg in mixed urban and highway driving (but more highway) in NYC and the tri-state area. This isn't that different from my former X3 (2015) which I got about 17-18 mpg. This is mostly Comfort mode with ASS turned on. I only have 1800 miles so far, though.

 

Wow

 

Hey guys I was wondering what kind of mileage you guys were getting in your X3's. I do a lot of city driving and I'm currently averaging 16.3 mpg

The 30i is the one to get if fuel economy is your target.

M40i is certainly a fun vehicle and has more get up and go.

Here's an anecdote for you. I never got the advertised mileage on my M4. Know why? Because it literally begs/coaxes you to drive spiritedly ALL the time.

Is the engine in M40i the same as the other 40i, for example

http://www.fuelly.com/car/bmw/440i_gran_coupe

Doesn't look that bad compared to figures above. But there again I concur with Mr M4 above, I have a heavy right foot.

 

I am on my third fillup on a M40i and averaging 27mpg in mixed driving.

 

That;s really interesting - I could live with that esp. cos your US freaky gallon thing is like factor of something like 1:0.8 imperial. Thx, I'm not so disturbed now switching from the diesel .

 

I had to take our 30i xDrive in for repairs today. I live 92 miles from the BMW dealership I prefer to deal with. I leave the house before 5 a.m., avoiding most of the rush hour traffic and getting there when the service department opens at 7:30 a.m.

I keep records of our X3's OBC MPG and the actual "gas pump" MPG. Since new, the OBC MPG has been 3.7% lower than the actual gas pump MPG. But, the correction factor is slowly drifting from -3.7% toward zero. I had the dealership adjust the MPG calculation last week, reducing it by 3%. I didn't have them do the whole 3.7% because of the drift toward 0%. With the drift, I expect the error to eventually go away and then go positive.

This morning, the car showed an indicated 36.2 MPG for the 92 miles drive. That was in EcoPro, but with the air conditioner on. Accounting for the remaining error after adjustment, the real MPG still would have been 36.0 MPG. A previous morning trip over to the dealer yielded 34.7 MPG, adjusted for OBC error. I started today's trip 15 minutes earlier and had good luck with traffic lights.

I'm running the tire pressures at four PSI over what the door jamb decal says, to have the tires wear down evenly (another of my efficiency and math games). I also have the OE non-run-flat tires, which adds ~1% to MPG.

Coming home, I had more traffic, made three stops, and was lugging 270 pounds of bottled water from Sam's Club. (Our tap water tastes horrible. Even our cats don't like drinking it, and they lick their own butts.) On the return leg my trip computer MPG was 29.5 MPG (so maybe actual 29.3 MPG).

The dealer's service manager said that I'm the only customer who's asked to have the OBC MPG calculation adjusted.

 

92 miles and it takes 2 1/2 hours to drive? No highways, just streets?

 

I am averaging 24-26 MPG 70/30 city/hwy while running the AC and driving about 75% in comfort mode vs sport or eco. I haven’t really found eco pro to save much fuel as I experimented on a recent road trip mode with cruise control on. Maybe 2-3% percent savings but I’ll run this mode when I want to feel like I am being thrifty. My preference is sport for the acceleration boost but it can be a little jerky in stop and go city driving. Either way I didn’t buy this car because I prioritized fuel economy not to mention I have a lead foot (when I am not in soccer mom mode).:rofl:

 

M40i, 10k miles on it, With Bridgstone Dueler RFT 19" tires, 33psi front and 36psi rear. At an indicated 80mph, which is really 77mph (normal BMW speedo error), 31mpg, going from Illinois to Wisconsin. At first I couldn't believe how good the mileagae was so I watched it closely coming back and it was about the same. All in all I ended up with about 30.5mpg on the expressway. And I'm not a lightfoot driver given any opportunity I'm passing someone and I'm comfortable at 100mph, although on the expressway in little traffic I do like to use cruise control and then relax. Everyday suburban driving to and from work, 10 miles with about 12 stops, i get about 18.5-20.5mpg depending on season. City driving I'm well under 17mpg probably in the 15mpg range.

 

I have just shy of 19k miles. according to the OBC I average 27.2 MPG. My commute is approx. 7 miles with a mix of freeway, and city. My wife's 2015 Toyota Rav4 limited AWD averages just over 24 according to it's OBC. I am thrilled with the mileage. I leave the X3 in comfort mode, and seldom mess with the ASS system. I also use the brake hold feature, which I love.

 

I set a new record this week. I took Frau Putzer to a doctor's appointment in downtown Bubbaville, 15 miles from home. I caught every light green except one. My displayed MPG is drifting in accuracy. After being adjusted, it's now again drifted to the actual MPG being 2.0% less than the displayed MPG.

After adjustment, the MPG going over was 41.9 MPG. I lost one MPG between letting Frau Putzer off at the front door and driving around to the back of the parking lot to avoid door dings. Round trip was 36.9 MPG. I got a few red lights on the way home. That was all with the AC on, because this is Floriduh and it's August.

 

I get 46.6 mpg. but mine is a 2.0 litre Diesel 👍

 

... and Imperial gallons (1.2 U.S. gallons), too.

Since new out X3's got 24.1 MPG, since it does a lot of short trips. We never got a diesel G01 in the U.S. BMW stopped selling diesels here right before the G01 started production.

 

According to the readout on the instrument panel and with only 3,400 miles on the car, I'm getting 28 mpg combined city (85%) and highway (15%).....and I ALWAYS TURN OFF the ridiculous "start-stop" function. I'm not a "slow poke" on starts from stops but I also don't try to spin the wheels either...LOL. If I see the stoplight turn red and I'm half a block away I ease up on the peddle, I don't coast I just ease up....just basic common sense. I'm not trying to get better mpg.......just driving like normal.......and I'm very pleased with the MPG. My trade in was a 2013 V6 Nissan Altima which got about 27mpg on regular fuel.

 

In my brand new xDrive30i I've been getting better MPG's than expected, at least within my gentle-driving 1,200 mile break-in period (as I write this I have 1,179 miles on the vehicle). I was shocked to see that in 70/30 highway/city driving the MPG gauge peaked at 29.2 for my last tank, which is higher than the all-highway rating. I also turn off the start-stop function. I'm sure things will change when I start to air it out.

 

My 2020 X3 gets 99+ mpg in town and around 42 mpg on the highway. Oh yeah, meant to say, I have a 30e hybrid!

 

Show off!! I don't have my X3 yet but I'm looking forward to the "raise" I'll get from improved gas mileage compared to my M3!

 

One other thing with the 30e. There is NO spare tire option. In the 30i, the gas tank sits under the rear seat. The spare tire option sits in the cargo area and raises the deck about 2". In the 30e, The battery is mounted under the rear seat and the gas tank is under the cargo area, raising the deck about 2" so there is no place to put the spare. I don't have a lot of experience with the "run flat" tires yet but so far, so good. We will see how they wear. The ride is more comfortable than one would think, keeping in mind that one does not buy a BMW for a soft, cushy ride. We find the ride to be comfortable, even on 400+ mile trips.

 

Since the space still exists under the rear deck but is too small for a spare, get a 12 volt air compressor, jack, lug wrench (they don't give you one) and a tire plug kit.

The commonly accepted myth is that run flat tires cannot be repaired under any conditions...none... not at all.. if you get a nail in the center of the tread then you need a new tire.. That is not true.

Look up the details on the tire manufacturers web sites; some do allow repairs with a few caveats;
1) The tire cannot be driven on while flat. It still must have at least 15 psi while driving on it. Driving on run-flat tires is very hard on the sidewalls of the tires, they heat up and the stresses begin to break down the belts.
2) The repair cannot be anywhere near the sidewall.

So, if you are zipping along on the highway and suddenly get a low pressure warning on one tire you need to pull over immediately and get air back in to that tire. Do not let the pressure drop all the way down while the car is moving.

The tire can be patched (ideal) or plugged (less than ideal, and it depends upon the method). Tire shops may not like working on run-flats because they have a different bead design and are very difficult to break the bead (when removing the tire).

Personally, I carry a plug kit, jack, air compressor, lug wrench and a bottle of soapy water.

Some of this can be done on the vehicle, find the hole (probably a nail or screw still stuck in it) and depending upon how much of a hole I will remove the object and insert 1-2 plugs. Then put the tire at full pressure and squirt soapy water to see if bubbles form, that would indicate that the plug has not completely filled the hole.

What I use is this; Dynaplug® Online Store | Dynaplug® Pro Xtreme - Tubeless Tire Repair Kit

I have plugged tires in the field before. If you do off-roading or own an ATV where you are going to be away from facilities its always a good idea to carry a tire repair kit.

At the worst, you are out the cost of the little rubber plugs that get inserted in to the tire. At the best it saves you $250- $400 for the cost of a new tire. Maybe when you are in some really remote area where they do not stock run-flat tires and you have to wait for a day for a new one to arrive.

 

I just wish they could have figured out something with the battery placement that did not eliminate the option of getting the spare tire. That was an issue for me too.

 

I got a hankering for some turnip greens and lima beans tonight. So, I hit Cracker Barrel, ~32 miles round trip. It's finally down in the 60's at night here, so I turned off the AC and opened the sunroof. I left the house at 7:30 p..m., missing the Friday night traffic and dinner crowd at Cracker Barrel.

I had my displayed MPG adjusted last year, but it's drifting again. For the last tank of gas, the actual MPG was ~2% less than the displayed MPG.

I drove "hybridly" in Eco Pro, with with Auto Start/Stop (AS/S) disabled. With that ~2% error, a displayed 41.2 MPG would really be 40.4 MPG.

 

If I am to believe the computer, my last average over nearly 400 kilometers was 31.8 mpg of highway and city driving strictly on Sport mode.

 

Wife gets 25+in town-28+ on the road with 30.

 

I got all immersed in my rant and forgot to post that my wife gets 15.5 mpg city in the xdrive30i. Totally not representative only because her commute is 3 miles all hills. Car doesn’t get a chance to warm up. I have to drive the car once a week to make sure the oil gets a chance to get hot and burn off fuel dilution and condensation. During my commute (65% city and also hilly) I average 24.5 mpg with her car. I tried ecopro one day leaving auto stop start on and got 27 mpg.
