Hi Everyone.

I'm after some owners experience as I'm considering changing from my E90 330D which is remapped to 287BHP.

I'm after something a tad smaller, and a hatch would be useful, plus I had an M135I as a loan car and really enjoyed it.

I'm currently averaging around 42 MPG with a mix of motorway, country and London City motoring.

I appreciate that it's not the be all and end all, but in owners experience, what sort of MPG can I expect in the real world on an M135I Auto, is 35MPG readily achievable with a bit all self restraint?

Thanks in advance.

Hmmm, I'll do some sums tonight at the sort of figures discussed to see what's what.

I do between 2000-2500 miles a month, claiming 45p per mile for the first 10k, then 25p for those thereafter, from my employer.

As a result, MPG isn't the be all and end all, but if I ended up averaging 25 rather than the best part of 45, the difference comes straight out of my wallet.

A quick finger in the air calc says I'll be around £1250 a year worse off running an M135i over a 330D, on fuel alone.

Hmmm.......I think I can think of better things to spend a grand and a quarter on per year.

Thanks for the replies everyone.

I like the 330D, but something a tad smaller would be useful for parking in London and a hatchback would fit into family life a bit better.

What really attracted me to the M135I I drove was that in 5 door form and in Grey, it was fairly non descript, and that really appeals!

Still, the whole big engine/small car thing is a winner in my book, and I'm struggling to think of something that would tick as many boxes for me.

I might try and get an extended test drive of one so I can use it properly for a day or so and see if I can make it work.

We went from E91 335d to M135i; in some situations, the newer car is better on fuel.
We get over 300 miles on a tank; the mpg for such power is amazing.
Even hooning across Europe to Germany, we got 30mpg.
It's also far more fun than any diesel.

We've gone from two diesels to two petrols; far better.
What range were you getting from the 335D?

I'm getting around 525 to a tank on average.

Really, I'm surprised at that.

Maybe my decision to go remapped 330D had some merit after all.

It's crazy really the importance we place on MPG when changing cars, as obviously it's only part of the equation.

I'd got myself in a frame of mind in the last few days that my current 330D was great, offering a fantastic compromise between performance/fuel economy so all was well with the world.

Then I came back to the car to find and M135I 5 door in black parked next to me and I'm undecided again....think it's just an itch I've got to scratch.

Yeah, I appreciate that ultimate fuel economy is not what the M135I is about of course, it's just that for what I want the car for, it is the only real sticking point, so if I can coax it into half decent economy figures when I need to then all is well.

Why stretch to have a car that you have to drive slower than you'd want? Id rather get a 125i and know that I can thrash the pants off it all the time!
Drive it slower than I'd want?

Not at all. My question was/is that in the event that I need to use the car on the motorway for a 200 mile slog sat at 70-80 for long periods, is the M135I capable of being relatively fuel efficient? The answer would appear to be yes.

With enthusiastic use obviously fuel economy will drop off massively, and that's fine, I just wanted owners opinions to avoid me being stuck with a car which was incapable of delivering any form of decent economy in any conditions.

Thanks for your help, I'm going to view one on Tuesday.

ha, just to clarify, the questions wasn't can I afford to, rather how much extra of my hard earned cash would it consume.

Quick calculation would suggest it will cost me between £1.2K and £1.5K extra to fuel to swap from my current car to use an M135I.

We'll see what tomorrow brings.
