Poor MPG
My X3 35D M Sport is not great on economy , is there any ecu software upgrades?.
My car was built september 2011, delivered November 2011. The MPG has steadily dropped from 40MPG too 33MPG now, no oil used and no faults indicated, drives great Just sh*t economy, it's going in next week to be checked if all is well it's going, I want more than this from this car. All my driving is "out of Town" so no stopping and starting.

I'd be happy if I could get 33mpg in my 30d but I can't keep off the throttle!
Worse still, got 15mpg on the same runs in the N20 328i loaner I had this week

Can do 6 litres 100km
Hi all
The 6 litres /100 km claim by BMW is possible!! You would have to doing under 100kph on flat road on cruise control with no interruptions. We have just completed a 14,000km trip as part of the 19283km done since new. Average consumption for the total travelled 7.75 lt/100km. Best 6.8 lt/100. When we crossed the Northern Teritory Boarder and found the 130kph limit we set cruise at 130 and the computer showed over 9lt /100km!! 110 km cruise seting we were doing under 7lt/100km. Head wind or tail wind could make 1lt/100 difference. We have got to remember that the BMW figures are on a rolling road with no interruptions and a prescribed resistance. All constant, no interruptions like a full throttle acceleration to pass other traffic etc, conditions that are unlikely on the road. We ar very happy with our 7.75 average, as it provides a level of performance and economy unlikely to to be bettered by a similar sized car. KF |

Our best of 6.8
Hi Our best consumption was 6.8 litres/100km was at about 5000km. did not exceed 100kph on high way cruise. No real difference now that we have done nearly 20,000, the the last fill was 7.0 lt/100. The driving conditions or wind seem to make more difference.
Hey guys the 7+ per 100km is great. Just check out a Q5 that does not have the grunt our X3 has, none were under 8lt/100, most over 9lt. Our Fabia, factory claim is 5.3 our best 5.7 but all other fills are in the 6 to 7 range. The factory claims are possible but I want to enjoy the performance at least some of the time. KF |

33 mpg UK is exactly my average since the beginning of time.
Observed minimum 60 mpg UK (at a tick over 50 mph on cruise control on an absolutely flat and empty autobahn with very smooth surface, no a/c or other electric consumer, counter reset after engine warmed up), observed maximum was 20 mpg UK (recently, crazy city traffic with a/c on). I also found - or at least think - that the higher roll resistance of winter tires in winter and the use of aircon in summer are a zero sum game. Realistically, everything that is under 35 mpg UK is very good and you'll rarely see it. Don't think the 35d is terrribly different from the 30d in that. |

For my 30D I get mid-20s if I thrash it. 35 to 37 with more normal driving on rural and main roads. 37 on the motorway at 70mph.
Driving really carefully on a 150 mile trip on a free flowing motorway I managed 47mpg but this was driving with the trucks at 60mph.

My 2000 4L petrol Jeep does 0-60mph in about 10 seconds and with average driving does 16.5l/100km or 17 MPG (UK)
I so can't wait for my 35D

Anything over 35mpg in real world driving is going to need a bit of restraint. Like keeping to speed limits with moderate acceleration. HighlandPete |

It's the wifes and it will do 68MPG, NO BMW does that.

MPG shortfall is getting even worse these days, as official figures are stretched by ED features, but real world driving still needs nearly as much energy to get about, unless we can tap into the ECO features. I've just been reading about the new releases for the F30 3-series. The 330d F30 M-sport is given a combined figure of 57.6mpg. Now think about it, that is almost a joke, we know there will be many disappointed drivers, as that sort of figure will need a very careful and easy driver. How many 330d M-sport drivers are going to drive like granny? What's the real figure going to be like for the average driver? About 40mpg I'd suggest. I note that Honest John reports about 27mpg for real world mpg in the F25 X3 35d. How big the data base I don't know, but the figure for the 3.0d at 34.9mpg gives a feel for where these cars are pitched. BTW, the E70 X5 is also turning in much lower figures than drivers expect, 27 - 29mpg are the sort of figures many report, even driving decent runs. We are well into stupid official benchmark figures, like we had years back, before we moved to the current test regime. That too became a joke, as manufacturers were aiming for 'headlines' rather than real world driving economy. It's now so flawed it needs revision, but it appears the official bodies just don't know which way to do it, as it has to be controlled and an 'honest' comparison across the makers models. It needs more data for the customer, but that can confuse even more. Peter de Nayer's test system is much more representative of reald world conditions. But if that was applied, car makers could have egg on the face, and the powers that be wouldn't be meeting CO2 targets. HighlandPete |

The little KIA 3 1.4 diesel is quite a revelation, the wife had the Ford Fiesta 1.4D Titanium before, this KIA knocks it into the sea, it's miles better in every dept. I can afford the fuel I just begrudge giving this government 25% of every gallon in TAX I am looking to down grade (engine wise) in the future as here in the UK speed restrictions are rife with old bill up every slip-road, so I find I have "fallen into the trap" and no longer enjoy my cars but just drive them sad days indeed.

after 7000 km with my 2012 X3-35d i am on average 38.6 MPG. This includes 3000 km with lots of runs in 200+ km/hr on the german Autobahn :-) . I'm very satisfied with the fuel consumption. And the car is a blast to drive.
I converted the MPG from Liter/Km on http://www.markporthouse.net/rangie/...onversion.htm# to be sure i had the correct UK Gallons. (1.2 US Gallons = 1 UK Gallon) Cheers.

The only way you ever get near to official figures is to accelerate slowly, and stay off the brakes. When you see a junction or traffic ahead, get off the accelerator ASAP and avoid the brake (unless you need to stop obviously!). Even then you will only get close to official figures, rarely will you match them.
Trouble is BMW buyers like us buy BMW's because we like to drive in a 'spirited' way and we perceive BMW to be a performance car brand. These days I'm afraid, 'performance' cars are not what the planet needs! Hence my 20d which can be coaxed to do about 46mpg on longish journeys, but struggling to get to the 50.4mpg claimed officially unless the journey has A LOT of 60mph-ish stretches with few interruptions, pretty rare. |
