What is everyone getting on fuel consumption?
For me
- 29.1 mpg across mixed driving (about 60% London traffic, 40% longer drives)
- Worst tank 20.8mpg (a whole tank of very heavy London traffic, probably never exceeded 35mph)
- Best tank 37.8mpg (pure motorway)
To put that into perspective S205 C63 4.0 TT my commute 75 miles round trip I get around 28mpg & buying one of these used 4-5 years old will net you a lot of value + main dealer buy 2 years AMG warranty bumper to bumper. For me

My long term average was 30.3 prior to the world going to shut in March and has now dropped to 29.5, doing less long trips and a few more drives for fun / pleasure. For me

Brilliant car. Have the mods impacted cruising mpg at all?
That, is a great question. I realised that actually I have no idea. I used to log fuel economy with the Road Trip app on my iPhone but I fell out of the habit ages ago.So a perfect time for a test. I accessed the hidden menu on the dash this morning and checked how much fuel was in the tank, it showed 44.4 litres.
I've commuted to work, which is 18.1 miles, 80% dual carriageway, 20% urban roads. I didn't have the aircon on, and I couldn't really have driven it any more economically if I tried.
Pulled up at work and checked the menu again, the tank is showing 41.4 litres. I'm fairly sure my maths is correct but I make that 27.4mpg ish, which is a bit of a drop as it used to average well over 40. I might do a tank average sometime soon to see just how horrendous it these days. Interestingly I reset the trip computer and the car thought it had done 42.3mpg for the trip.
Another figure that should be interesting is the power output. It's going on the rollers this friday, so we'll see what it's actually making.
Closest guess wins a virtual pint.

Do they have cylinder deactivation? 28mpg average is light years better than I've ever achieved in a V8 Henry_b said:
481hp and 675nm is my guess - 27 mpg doesn't sound bad to me ear, or wallet being I can average less than 5mpg if I so wish in my beast of burden lol
Longer runs I did Manchester which was into 30’s but then M6 accident traffic pulled it down a lot. It’s got deactivation - coast mode.
Epic engine and as nice as a 3ltr I6 is a 4ltr v8
Dyno day yesterday. Enjoyed a really good day organised by Marc at Williams Performance. There were 7 cars ran in total:
My 2017 BMW M140i
2018 BMW M140i
2000 BMW E39 M5 Supercharged
Williams Performance 2004 BMW E46 M3 Track Car
2019 Hyundai i30N
2019 BMW M2 Competition
2016 BMW M3
Quick brew up before heading down to JM Imports in Newcastle, they primarily deal in JDM imports and building big power GTR's.
A quick peek inside the toy shop down at JM when we arrived. Jurgen's Huracan is twin turbo and Syvecs, and his white JUN GTR at the far right is I believe the fastest full weight street GTR in the UK. His 100-200km Dragy time in it is 2.40 seconds
Marc's M3 ran and made 351bhp which was pretty healthy for effectively a stock car with the CSL airbox.
Then mine went on:
Really happy with how the car performed. JM's dyno gives a wheel horsepower figure and they use a figure of 15% transmission loss to calculate power at the flywheel.
So the figures I got were:
At the wheels : 505whp / 493ft-lb
At the engine : 597bhp / 580ft-lb
Was a nice graph as well, shows just how mental the mid-range is.
Tim Williams came along for the day and ran his M140i, he does YouTube things so I think he's doing a video on the day which will be quite good to watch. He was a really sound fella and nice to chat to. He chucked me the keys for his car which has a Quaife LSD fitted, so that was quite interesting. Mine pretty much hooks just as well in a straight line, but his was far far more controllable to slide about, so I think that could be on the cards as a future modification.
Real world performance wise, I had a crack at a Dragy run with it yesterday, but the surface wasn't completely dry so I was struggling for grip and got some wheelspin. Still ran a 6.9 100-200km though. I think there's fairly easily a 6.5-6.7 in the car.
So there we go, finally got some figures after fitting the Pure800. Nice to see it's making good power and the graph is smooth and progressive. Obviously every dyno is different and conditions vary so it's obviously an estimation, but coupled with the performance of it I'm over the moon.
No plans for any more power, just maintenance and possibly some big boys suspension and an LSD next year, but we'll see.

Thanks for the update !
Great job on the cleaning, and dyno, I can't imagine how yours must pull. I am getting bored of mine at 411bhp/576nm and keep being tempted by a sports cat and hp fuel pump.
Thanks mate, appreciate it.Great job on the cleaning, and dyno, I can't imagine how yours must pull. I am getting bored of mine at 411bhp/576nm and keep being tempted by a sports cat and hp fuel pump.
It’s a really bizarre thing. When I take people out in it they’re really taken aback by the performance, but I think I’m just quite used to it now so it’s seems fairly normal, which is testament to how usable the car is.
I drove a 470bhp one on Friday with a Quaife diff, and it really felt quite tame, which is madness as a 470bhp hatchback is very clearly a quick car indeed.
What map do you have on yours currently?

I took mine to a BMW specialist tuning place called 'A Reeve Performance', in Kings Lynn. Great chap, very professional, and put his own custom map on my car.It’s a really bizarre thing.

Bit of a random period with the car over Christmas, I got very close to selling up.
I think part of me realised it's probably still worth a reasonable amount currently, as are the mods if I returned the car to standard, and I had thoughts of moving to an E61 M5 and a daily Citroen C1 or something. My thoughts were that the M5 would be likely to hold it's value better and still be a bit special. The overwhelming feedback generally from people was that an E61 M5 would be a terrible "nice day car" and I'd be better off with something sporty. I don't agree with that at all in fairness, that might work for some people but I have a serious barge habit and I love fast estates, so an E61 M5 was far more appealing to me than say a Boxster or something.
That said, over the past few days I've been re-reading the thread and thinking about the whole thing. I bought the car originally knowing fine well I do big miles and that it was going to depreciate accordingly. I also love driving the car and it has a real Jekyll and Hyde personality, you can mooch to work in full auto and eco-pro and it's basically any sort of cooking spec commuter with a decent sound system and comfy seats / cruise / all the stuff you need, or it's a right hooligan if you turn everything off and give it some stick. So really nothing has changed, my requirements for the car haven't changed, it still meets what I need and I've had no reliability issues at all with it, so there's absolutely no reason to change.
So it's getting a new seat of rear tyres this week, I haven't been able to get hold of Pilot Sport 4's so I'm going to try Eagle F1 Asymmetric 5's. It's also due an oil and filter change to that'll be happening shortly.
Then I think once the decent weather comes back, I'm going to look at getting a spare rear subframe and diff and polybushing it up, and building up an LSD then I'll swap it all in. I'd like to look at some decent suspension so probably a set of KW coilovers or something similar, perhaps the underbody brace and M4 lower control arms.
Marc at Williams Performance is also looking at sorting out an inline fuel flex sensor for accurate ethanol content monitoring, and I may look at full 3.5/4" exhaust system, then turn everything up a bit, at the moment the turbo is just ticking over really.
