Mazda6 wagon: Actual = 24-26 mpg (EPA highway = 24) Murano: 22 (EPA 23) G35 Coupe: 24-25 (EPA 23) Forester: 25-27 (EPA 26) Q5: 28-30 (27) I'm averaging 27 to 29 mpg highway in the X1. I'm simply not accustomed to seeing 15-20% below EPA ratings. I don't have a right to be disappointed by that? The car goes in for its first service Friday, and I've asked them to look for issues that could be hurting fuel economy. But based on what many other owners are experiencing, I don't expect them to find anything. I think I'm just one of the unlucky ones. |

Also low tire pressure, open windows, headwind would harm. Lastly, did you notice if there's any elevation difference between the start line and finish line? It could be bloody.....say, climbing the hill while testing. I'm not familiar with Holland area

That my wife, who is very far from an aggressive driver gets about half the mileage that I do in the 35i leads me to believe that yes, it is the driver. If the 35i can show that big a difference, I would think the smaller engine 28i can show even more of a difference, given the same car. And the conditions cars are driven under may vary too, which also isn't a fault of the vehicle. Of course, there could be unknown reasons that only occur in some vehicles some of the time, but somehow I doubt it. Introducing unknown reasons on top of the known reasons goes against Occam's razor. |

I started paying more attention to my mileage recently and admit it is not as good as I expected. But I have a roof rack on it and even without bikes, it affects the mileage a lot.
My thought is this, I bought a BMW for the driving experience and honestly don't care about the mileage that much. And yes, I drive a lot. I have had the car for 2.5 months and have 5,700 miles on it. Just put your foot in it and put a smile on your face. |

But how? I want to hear from those who do true city driving (not the EPA sub-urban cycle) how they can achieve better then 20 mpg. |

I believe I do "true" city driving, in the heart of Los Angeles. I have the sDrive281. My morning commute is 18 miles (mostly open freeway, because I leave at 5:30am for the gym before work). Coming home, traffic is pretty bad. The rest of my driving is local/street driving. I have had exactly one longer trip since I got the X1, about 200 miles round trip. Otherwise - city driving, LA style.
So my trip computer - never reset - shows on approx. 8000 miles, average speed 33.5 and avg MPG 27.3. I am satisfied. I think the xDrive28s seem to be the ones with a lot of variability... |

Are you guys calculating mileage using the on board computer or by dividing mileage driven by gallons of gas? Having to go from liters to gallons is a pain... But that is the most precise way of getting the mpg. I do not trust the computers in the car to give accurate readings.

Well I would guess that I am doing close to 50/50 on city/highway driving. The 18 mile morning commute Monday through Friday is highway, at speeds around 70. Takes me 20-22 minutes on average. Coming home the same route takes me 40-45, so that should show how bad traffic is then. A lot of crawling along, accelerating briefly and then slowing again, etc.
But the rest of my driving (shopping, errands, etc) is city streets, with the badly synchronized traffic lights and so on. And my residential area is full of stop signs. So if it's fair to say I drive about 50/50 city/highway, I'm getting just around the EPA estimate of 28mpg overall. |

Less in a 35i, obviously, but still around 350-400 miles, depending on driving. That's not bad at all. I can fuel the car for two weeks for less than a restaurant dinner costs.
But speaking of refueling... is it just the 35i that's extremely cautious and will tell you it's on the reserve when there's over a sixth of a tank left? I hear the DING, look, and think "On the reserve? With 70 estimated miles left?" I can drive two days to and from work on that, and still not get near empty. Or is it the fuel warning that's wrong (bad translation?), and that it's really NOT on the reserve, or anywhere near, but letting you know you might want to refuel soon? |

Mine x28i get 360-380 miles, mostly city drive with 2-3 times 20 miles hwy drive. The tranny is built for hwy driving. Now that I get stuck in city life, I'd rather go wild in driving pattern and not worry about gas meter.

On a driving trip from Sacramento to San Diego - down Hwy 99, up and over the Grapevine on I-5, then cut east on the Foothill Fwy to Rancho Cucamonga (80+ mph in the carpool lane!) and finally landing in San Diego - averaged 34 MPG by the trip computer - peaked over 36 while on the flat land from Sacramento to Bakersfield. I'm very happy with the economy and the go-fast capability of the N20 engine. 2013 X1 28i Sportline.

Want better mileage in miserable stop and go L.A. style traffic? Buy a smaller, lighter, less powerful car. Simple as that. |

My commute is only about 23 miles return daily and only 7 miles of that are over 60mph. I am in my 30th tank and avg speed is 24.8miles (40km), avg 22.1mpg (10.8L/100) by on board computer. My own calculation shows 20mpg (11.76L/100). That's right, not even getting the City EPA, off by 30% by my calculation, left alone the Hwy EPA. I am trying to change my driving style (coast more) and see if it makes any difference. Vancouver might claimed to be a world class city but not when it comes to road system comparing to the US. Vancouver's highway speed (2 lane wide is common) isn't that high most of the time due to traffic, and those live in the city tends to just travel within the city to get all things done. All I really wanted was to high the city EPA. Low file consumption surely should't be the main decision factor when one purchased a BMW. However, EPA to Performance ratio certainly is on most people's mind. I think it's fair to expect the vehicle to perform up to spec within a reasonable tolerance. I think the Prius drivers would also be unhappy if 0-60 takes 18 sec. even they never expect the car to fly. |

They're measured after the fact, and are not numbers that manufacturers need to meet or approach. Quote:
And they got that; what they didn't understand, and what one of them still refuses to understand, was that it doesn't deliver all of that at the same time. EPA classified the X1 as a mid-sized car, not an SUV, and not a sports car. They never tested it for occasional spirited driving, nor with load exceeding one skinny driver; both features you expect from the car, and which it's advertised for. And which you cannot have at the same time as good mileage. If you think the numbers are off, complain to the EPA. Unless you think BMW cooked the numbers by delivering a "special" X1 version to EPA for testing, I cannot see what beef you would have against BMW or the X1. tl;dr: If you're disappointed because of the mileage, you should be disappointed with the EPA, not with the car. It delivers. |
