according to my on board computer, i'm getting 27.7mpg over the last 800miles which i was amazed at. However, i am almost definitely driving it like a 'granny' but fast enough for me! (mixture of motorway and town driving and always let it warm up - shell v power)
I’m lucky to see 220 miles on a tank. My commute is 10 miles on the nose, but it’s stop start traffic for 2 miles then hilly A roads which doesn’t help matters.
I did get around 300 from a tank on a journey down the A1 to Stevenage and back, which wasn’t bad and gives me slight comfort. I’m planning a 3000 mile jolly for next summer so I don’t mind the thought of achieving 22mpg average over that.
On a run theyre actually really good considering the engine. I got from Calais to the Nurburgring on one full tank (300 miles or so) doing the speed limit.
Compared, my M5 needed 2 tanks on the same journey
firstly only had the car 2 weeks so getting used to life with the beast.
what fuels are you all using ? with the amount i fill up i opt for tesco 99 as it pumps up the clubcard points 2 weeks into ownership and iv noticed one thing they are pretty good on fuel if you can resist pressing the M button and listening to that snorkel calling for air in the bonnet ..
i had my car from sytner tamworth and the assured it was an approved used fsh etc but couldn't tell me when it had the plugs changed,
so i replaced them for a couple of reasons, firstly a slight unsteady idle when slightly lifting the throttle in neutral and hopes of giving it the best chance of economy as the plugs are used to feed data back to the ecu with regards to how the engine is running as well as creating a spark so they are a very relied on part..
after removing i noticed instantly the gap difference
after rebuilding i instantly noticed the difference with a more balanced engine/ faster throttle response and the effficiency at 70 mph will hit 30mpg
mine hovers around 22mpg but with fair bit of London driving...
Even if you could do 300 miles, how do you put up with the constant low fuel warnings?! I had to code that to 1/8 so it isnt so annoying!
Mine loves its washer fluid too
I get around 230 miles to a tank
I got 238 miles from my last tank. Equates to 18 mpg. Mixture of motorway and urban
I’ve got a 4hr Drive to Harrogate tomorrow so it’ll be a good test of economy. If I can resist blasting the fućker!
Average 20mpg on the nose over ownership, according to the on-board computer. Calculating using actual mileage covered vs litres used, this is more like 18.5mpg - the computer is generous and the 'range' it indicates after a fill up is an absolute joke, the car is dreaming. .
I used to get around 220-230 miles from a tank, mixed journeys and driving, daily driver.
I get roughly 18mpg but hoping to get nearer 11!
I get 180 miles between fill ups, I usually fill up on the second warning so 1/8 of a tank. Usually put in 54 litres, which equates to 15.5mpg.
Stretched it to 240miles once on a long distance run with only a little bit of fun, having just done the calculations that was only 18.8mpg fml
Depends what I'm doing. Short, local journeys kill the mpg, as does traffic. In my E90, I got anywhere from 220 to 380, depending on type of journey. Naturally, steady runs at motorway speeds realised the best mpg.
And for all those who say "You don't buy one and worry about mpg" or other such ********, it's very much a factor for 99% of people who buy something like an M3 or M5. I expect low mpg when I'm clogging it, but also expect a reasonable level of parsimonious consumption when I'm not. Sadly, neither my E90, nor my E60 M5 did the latter very well. :roflmao:
My E90 on a run to central London and back. Mix of traffic. Tank was full on departure.
That's brilliant that you can get over 300... Economy is definitely something that we need unless people enjoy throwing money down the drain.. I think the M3 does alright for what it is
You've hit the nail on the head Dan. For what it is, which is a relatively highly strung 4.0 litre V8, it does pretty well.
the more i read up about this the more i see how advanced the engine is along with the management system. driving to work this evening and its easy to forget you've got a 4.0L v8 race engine just chugging along at 1500rpm .. how bmw have made this work and able to daily drive smoothly is amazing
iv worked a few things out when in normal mode without the sharper throttle response (power button) pressed it feels lazy and sluggish but it changes the throttle map regardless of what you ask for below 50% throttle it jus gives an ample amount to get the car moving to maximize economy acceleration ratio
correct me if im wrong like
I always have power on now. Press option in m settings to adjust the starting configuration
