Just returned from a 500 mile, each way, trip, and my mileage was above and beyond expectations!

Drove my F56 Justa with manual, in Green mode, and recorded 45-46 mpg the whole way. On my last fill-up, it gave me a range of 508 miles, based on this.

 

Like!

 

The same thing happened to me recently except halfway through the tank I switched it into sport mode and well.. yeah lol. In all seriousness though I am really happy with the numbers I've been achieving. My avg is 37-38 which is 25%+ better than my GTI was.

 

Out of curiosity were you driving nomally? At the speed limit and not a lot of coasting?

 

As you can see, my average speed was 61 mph, and you cannot coast for 500 miles :-)

I would say that it was very normal driving, except in Green Mode, and all highway.

 

I'm averaging 40MPG in my Cooper S, pretty impressed as I've only done about 300 miles and haven't reset it since I got it...

I live in London too so a large amount of driving has been crawling through traffic...

I did do about 200 miles of motorway driving though...and whacked it on cruise at 70 in green mode.

 

The 3 cylinder is amazing!

I've seen a trip avg as high as 50.3 mpg in green mode....on a trip between LA and San Diego

 

Did you use hypermiling techniques? Or did you just set cruise and leave it up to the car?

 

F56 in Green mode employs 'hypermiling' on its own. When in green mode, when you're not actively accelerating and are over 30mph, the transmission and engine de-couple, the engine reverts to idle, and the car coasts. If you've set the cruise, it'll do this as often as it can (pretty much any flat surface or slight decline). The cruise even lets you drop 1mph or so during the coast and then re-engages to return you back up to speed.

Its fun to watch, set the dash display to current MPG, and it'll be trucking along at 35mpg range and then suddenly jump up to 99.9 and the RPMs will fall to ~800.

So if you're traveling somewhere that is mostly a decline the entire way, it can coast A LOT and get you amazing mileage. I bet that's what happened for Thumper?

 

Does the car display MPG with reference to the size of the gallon? We have gas mileage comparisons on this thread based in US and UK I think..
Maybe I'm missing something, have BMW finally solved the MPG language barrier?

 

The UK and US gallons are still different. I'm pretty certain that darex's numbers are US, I'm not sure on ryanm8655.

I'm getting 42mpg, US, highway, and low 30s city on my Justa so far.

 

I trust you have an automatic. That is amazing, I never heard of a car shifting itself into neutral before.

 

Yes I've got an automatic. I think it is specific to automatic as the owner's manual states that they car has to be in D for it to work. Strangely the standard still gets a better EPA mileage rating doesn't it? I don't think green mode is accounted for in those numbers.

 

I'm friends with the Automotive Director at Consumer Reports, and I shared this with him. He suggests that I do an independent GPS comparison to see how accurate the speedometer is, but my casual observations suggest it's close to being accurate, at the very least (highway radar signs match my display numbers).

I asked him if they're done testing their Coopers, and he told me the final reports are being written now. Unfortunately, their Justa is an automatic model, so it won't be a direct corroboration of my experience. I asked him, so as to make sure they do their own highway mileage testing too, which I think is pretty standard practice for them.

It seems clear, though, that the F56 easily bests the official EPA numbers promised, and by "real life" owners, too! An added bonus in my book.

(And yes, Sepp, I am US-based.)

 

I love getting up to speed on the highway and allowing the car to coast... then watching the Tach fall down to idle as it decouples.

Here's something in the press release from last year (3rd paragraph)

 

I'm in the uk so not sure how the mpg compares to the us.

Combined, it is claimed the car will do about 49 mpg in the uk, actually I believe it if you drive nicely in green mode.

 

Another reason why I should have purchased the automatic. Sigh....

 

At least you can drive a manual. I can't.

 

According to the radar signs set up on the side of the road and the GPS speed on my dash cam the speedometer shows 1.5 to 2 mph higher than actual speed (about the same as my previous car).

Nope!

 

I applaud your efforts. I drove to work this morning in Green mode and I wanted to punch that smug little fish in the face. It was the most infuriating, boring commute ever. Green mode is for people with much more patience than me.

I have just about 1000 miles on my F56 MCS manual. I am seeing just a little above 29mpg average right now with mixed driving. I have about a 25 mile commute to work. When on the freeway I drive in green mode but will use sport mode when out and about the city streets which may explain my lower average. I guess if I wanted great gas mileage I could have bought a Justa or an automatic but I bought this car to have fun and I really like driving around in sport mode for spirited driving. I thought I would give my 2 cents on mpg when not driving it practically every day.

 

Not sure how accurate the onboard dash instant MPG display is...
But I'm seeing 99.9 MPG too often when driving my MCS auto, way more often than any other vehicles I've driven with the instant MPG reading feature on the dash
Regardless how accurate it might be... seeing 99.9 MPG makes me very happy!

BTW, the dash shows 36.6 MPG average for my daily 60 mile round trip commute in Los Angeles traffic. Terrific!

 

This is most likely due to the coast feature that the auto transmission has. When coasting the transmission will disengage, your rpms will drop, and your MPG will read 99.9 MPG. This is why the auto is rated at a higher MPG than the manual.

 

No engine braking?!

I don't mind since it's not too hilly here, but others might...

 

Switch out of green mode, go to mid, and the coasting is disabled. See my post a bit above on how coasting works in green mode on autos.
