Don't get the fuel savings, my long term average on my 140 is 35mpg over the last 8K miles with 40 on a run, manual box too.
Maybe because within a mile of leaving home I'm cruising at 50 to 60 mph and have little town stop start journeys and each journey is approx 50 miles.
It must be the say the 10 mile creeping journeys that suck the juice, if so, I wouldn't have such a performance car anyway as a daily.

Beyond that, fuel savings is false economics.
If you calculate actual consumption in € sense, it's not much.

Purely hypothetical, if you drive 10000 miles a year, the difference between 30mpg and 35mpg works out to €200 worth of petrol.
Even 25mpg bumps the consumption to €500.

That's a cheap price to pay for having more power on top, atleast to me. Even if 25mpg -> 35mpg seem like massive gap in efficiency.

Edit: not sure what exact taxes are in UK, but here we have one-time CO2 tax and annual taxes based on HP, and these may figure more significantly, than fuel consumption alone

I don’t think it’s a contest if you want driving pleasure with useable power the M135i is outstanding. I know I have one but I was in the same boat as you looking for it and after test driving the smile you get from a turbo 6pot is unreal. Mine is the Auto and over 6000miles I have had it I have averaged 34mpg on a run driving carefully I can see 41-44 MPG as it has the 8 speed auto. It’s not too much power at all even for B road thrashing it’s still usable power. For the difference of 4-8mpg is it worth the saving for economy going to a 2 litre? If you want economy then got for the 123d or 116d 😂

I've had a 125i ms and 240i back to back. On motorways the fuel mileage difference between the cars is negligible, though the 125i has the slight upper hand. The real difference is in town / b road driving. The m240i delivers between 18 to 22 mpg, the 125i between 26-30.

As has been said, if you're seriously weighing up fuel economy then either you do one hell of a lot of miles or, politely, it's the additional cost of the mx40is that 's the matter in hand. The difference between the engines isn't just flat out speed, though the turn of pace with the mx40i can be fun: for me it's as much about the creamy engine and the available torque - 2K at 80 is nuts. It's a more refined driving experience, even at low speeds. I will find it hard going back to a 4-banger when the time comes (though as mine's a keeper, I'm guessing most cars will be electric by then!)
