I know it is not the most important thing with this car but....



Not bad at all! A gentle drive round the M24 for 41 miles while running it in so may get better.

Given the power available it's still impressive.

lol my first few days run in was 18mpg. Nice to know there's another side to it.

So looking forward to getting worse than that!

I use this app to track costs and mpg over time when you fill up the tank. I think I can see a correlation with mpg and when my engine run-in period came to an end!

@srbs73 which app are using? I’d it iOS or Android? TIA

[Amos91]

Pointless stats, I expect 90% of m340i drivers wouldn't be driving for 40 miles on the motorway at an average of 54mph.

Shock horror that driving slowly yields higher mpg!

It's called Road Trip MPG - looks like iOS only.

Thanks

All stats can be pointless and manipulated to show what you want!

But I do find it useful to see what is possible. I have no wish to go gently with it once run in! I do always drive slowly to work but faster home!!!!!

After all, 73.6% of statistics are made up

Realistically get one if your happy with 20-30mpg on average. Best Ive had over a distance is 39mpg and that was real world driving, going with the traffic flow and overtaking when necessary.

I find it surprising you say that when all I EVER seem to do when I come over to the UK is sit doing 54mph through 40 miles of roadworks on the motorway, monitored by average speed cameras.

And, just because somebody has a "sporty" car it doesn't mean they have to drive it everywhere at 9/10ths. That's not the real world and it's what I would expect from someone who is IMAGINING what it's like to own a performance car, rather than actually living with one. A bit like thinking living with a supermodel would mean sex three times a day, rather than arguing over who's putting the bins out.

The M Performance cars are BMW's response to people who can no longer stomach high taxes on full-blown M cars, and who are looking for something which has the performance when needed, but which also give great fuel economy. So discussing achievable fuel economy is AS relevant as discussing 0-60 mph times.

I didn't buy my R8 to drive three hours up the M1 on cruise control, but it's nice to know I can get 21mpg when I do so.

Drive in sport plus all the time. Get 20-22 mpg mixed driving. On all highway get 28mpg. Not interested in maximizing mpg's. It's not a Prius.

That's a pretty normal drive really when you go from A to B. It's still interesting as not all performance cars can hit those figures on the same runs.

It’s not about maximising MPG’s, but if you’re having to commute a fairly long round trip in heavy traffic, you can’t enjoy the engine anyway, you’re just burning money.

I think it’s great how you can stick it in comfort or even eco-pro when you can’t enjoy the engine and get a decent MPG and then open it up when you can.
