M240i city gas mileage
My car has ~1500 miles on it now and I’m getting on average 17.3mpg, that’s 100% city in Normal mode, engine start/stop OFF and not driving with a heavy foot. Seems a bit low?
What are you guys getting around town? Seems like it should be around 20-25mpg. I’ve read mileage and performance gets a bit better after a few thousand miles, maybe there’s some truth to this?

It really depends on how much creeping along you are doing and how long the trip is. I have to make a 3 mile trip in Chicago’s bumper to bumper traffic a couple times a week to take my kid to MMA practice and I get 11.5 to 14 depending how backed up it is. On the way back when traffic has calmed down, I get 17. I just broke 1200 miles.

Non highway and heavy foot will bring you to high teens & low twenties. I fill up once a week and commute to work 3 of those days which is 98% highway. I average 26-27mpg which is exactly as the window sticker specifies for mix between city/hwy.
On weeks where I do not take non-work commutes (100% hwy), I get around 30mpg. It doesn't help that I'm usually sitting at 85mph on the highway. The good thing about this car is if you want good mpg you can get it, you just can't have fun. |

When asked what kind of gas mileage I get, I always reply I don't care about mpg but only spg.....SMILES per gallon 😀😀

26 combined city/highway MPG City MPG:22 city Highway MPG:32 highway 3.8 gals/100 miles Link: https://www.fueleconomy.gov/feg/noframes/45477.shtml Based on your mileage your mileage seems a bit low compared to the numbers provided by the EPA. But the EPA numbers are not real world but are obtained in a setting/environment that ensures each vehicle tested is tested under the same conditions. I sort of suspect you are driving with a heavier foot than you think. But to be sure the engine's gas mileage will improve as miles accumulate. Lab and field tests have found via closely monitoring fuel consumption among other things that engine break in continues long after the nominal break in mileage is reached. (As an aside I bought a new 2020 MINI JCW in Loveland CO last Feb. 27. I drove it home (to NW Arkansas, Benton County) 873 miles. I followed break in guidelines and when freeway traffic permitted it -- which was often as I70 east of CO and through KS is not that busy for a freeway -- I'd let the car coast down to 50mph then accelerate up to 3K RPMs or higher. I did this a few times each time I had the room. And I picked up an up hill section of freeway to coast as this slowed the car's speed quicker. Towards the end of the road trip the JCW engine was running noticeably better. While I have broken in new engines a number of times I have never experienced nearly 900 miles of 1200 miles of break in over the span of 2 days. I recorded gas mileage but I didn't pay it any real mind. But with the engine clearly "loosening up" I'm sure gas mileage improved.) Be sure tires are inflated to their proper cold inflation pressure. As for auto stop/start you can enable it for a tank of fuel and note if there is any real benefit. I'm sure during the EPA test auto stop/start is enabled. |

Normal might mean comfort, since that's default?
17 MPG seems awfully low. I normally drive about 20mi a day and it's all city driving except for a 1.5 mile strip down the highway. In January i was averaging around 22.5, and that includes letting the car warm up in the morning and the end of the day leaving work. Now I'm seeing between 23-23.5. Always running 93 octane fuel. Most of the time I'm in comfort, sometimes eco pro, sometimes sport.

keep in mind anytime you are stopped you are getting 0 miles per gallon. To move from a stopped condition to say 10 mph you are also getting extremely low MPG due to overcoming inertia of the mass of the stopped car. Here's were the weight of the car affects the mpg...if i recall initial moving from a static stopped condition even with a mild throttle will only get ya 5-8 mpgs.
note: the above mentioned 0 mpg is of course if you don't have auto shutdown enabled. Still to move from shutdown to say 10 mpgs is extremely low mpgs. |

I drive in sport individual (everything sport+ except steering) and average 15-17 MPG city. my commute is basically all city with less than 5 minutes freeway. now, on roadtrips in comfort mode I get close to 30 MPG with all freeway. I could care less about the MPG because it's so enjoyable driving the car in sport+ mode.

yup, that's why you see such a variance in reported city driving mpg. Its all a matter of how much stop and go you have on your city route, huge degree of variability depending upon route circumstances, thus huge variability in city mpg comparisons.
