I just picked up my new M550i yesterday, and drove it ~200 miles. The start was rush hour, stop and go traffic coming out of Pittsburgh. The rest was highway cruising at 80-90, and there was more stop and go traffic due to construction for about 10 miles.
I averaged 25.8, which I'm fairly pleased with given the circumstances. I'll report back as I put more miles on the car. |

I too mostly go from Comfort to Sport Individual. Mix of city and highway commuting, I am getting about 19-20 mph. After 1200 miles passed, I definitely punch it every chance I get.
Slightly better gas mileage than my 2015 S6. |

I've gotten 30 mpg on an all highway trip! It's always 28+ highway if I drive conservatively. And 20-22 in mixed driving. This is comfort mode with stop/start enabled.

Just did a 454 mile trip (95% freeway, 5% city). I drove 82MPH (85MPH speedometer). The computer showed 27.6MPG... however, when I filled up the car, and manually calculated the mileage, it was only 25.5MPG.
Does this mean the odometer is also reporting higher, thus putting more miles on the car than is real?? |

While not a M550, I thought I would note that we just finished a 3,500 mile trip to Florida with as fair amount of local driving (plus 140 miles local since) in the 540xi and averaged 28.5 mpg for the trip. I thought that was pretty good. Drove in Sport mode the whole way. Haven't really used it around town enough to know but I 'll guess it'll average in the low 20s. We'll see.--Bob

Probably a good idea for more precise information. I am sure the mileage showing will be more favorable than reality. But I have to admit I have now gotten a bit lazy and will just enjoy the car and results it presents.--Bob

Ive got 16k on my M550xi. and i drive the S@#$. out of this thing. I think like most that got the M550I they wanted performance. At least thats what i wanted. but that also when driving conservatively she gets good MPGs. I would say when i go to N.C its about 400miles ill get 27mpg. but around home i am mostly in sport plus mode. shifter to the left in sport. and i have a piggyback tuner turned all the way up. and getting 17mpg. Now i always run 93 octane. The car runs the best on it. I can tell a difference between 92 and 93. I wouldn't think you could tell. but it does make a difference. maybe try a better quality fuel?

Now I'm over 18 MPG as the car probably breaking in as I approach 1500 miles.

I've been told the odometer is correct or at least more accurate than the speedometer. When calculated against mile markers, my speedometer is 3-4% off, 3 at 75 mph but the odometer is pretty close, even after 10 miles. The other side of MPG is the gallons. You need to make sure the fill up is the same. 1/2 gallon off can make the same difference.

I had my car coded and thought about coding the speedometer to be accurate (it can be done) but I opted not to as I like the security of keeping myself at a speed that won't normally incite a traffic cop. In my market you can go 9 miles over the speed limit and photo radar won't pick you up. So I set my cruise control for 10 or 11 miles over the limit. |

Just drove to NC, SC and back, along Interstate 85/10. Consistently, the car calculated my mileage around 31mpg, both ways. I was usually in ACC at around 75mph. The exception was in the NC mountains. On those twisties, where I grew up years ago, I was in Sport Plus, and the mileage dropped significantly! Imagine that! Love the M550i.

I know this is an old topic, but wanted to share my stats after driving from Florida to Ohio and back with my '21 m550i and Shell 93:
- First 3 hours in FL @ 80mph (flat roads) Eco mode cruise control: 31.5 mpg. Left early in the morning so there was no traffic. - Remainder of the trip (mix of cruise & spirited driving: 27.3 mpg (approx. 2300 miles). |
