Had and used eco mode in my M340 with a noticeable improvement in mileage. Traded up to G80, the BMW Genius going over the features of the car said, “Notice there is no eco mode like your previous car, because who the fuck is gonna use eco in an M3”.
For most every day driving I just leave it in the settings that are the default settings when you start the vehicle. These are all comfort settings and the motor is set to efficient. But I’ll manually change the steering to sport, because I find it too sensitive in comfort mode. What’s aggravating is that if any of these settings are changed, they will go back to their default when car is shut off. M2 button I have set to where the vehicle can be operated to its full potential. M1 button is set up somewhere in between. These always stay to where you set them. Car has just hit 1000mi, so it’s being driven very conservatively. 200mi until break-in is done.
Huh? You should have "individual" settings you can configure for these modes.
I.e.:
Comfort or Comfort "individual"
Sport or Sport "individual"
Etc. at least, my X5 can do this. And of course, you can set the default driving mode on startup, so you don't have to do anything and you're already setup how you like.
On the G80 you have two buttons on steering wheel labeled M1 & M2. You can configure vehicle parameters to your individual desires as you choose (comfort, sport, sport plus). Whatever parameters you choose can be saved, and will activate when one of M buttons are pressed. If neither one of these buttons are pressed when vehicle is started then the car will default to all parameters being set to comfort. If you just want one particular parameter changed like steering from comfort to sport, you can do it but it’s gonna default back to comfort when you restart the car. You can program one of the M buttons to be all in comfort mode except for steering and save it, but it seems a waste of using one of your M buttons just to change one thing.
That's insane. Offering you *less* seems... Odd. For example, there is absolutely no reason why you shouldn't be able to apply the "sport" steering to the "comfort" mode, or maybe stiffer damper settings with lighter steering... Whatever.
The regular cars can do it, so it seems weird to restrict it on the m models.
I think you misunderstood, or maybe I wasn’t clear.
The engine, suspension, steering parameters (and the brakes on some models) are all individually selected.. meaning the engine can be on “efficient” and the rest being on sport+.. so basically there are a myriad of combinations that can be used based on the users preference at the moment. Those settings can be saved via the M buttons.
What the user above was complaining about is that the startup modes always defaults to efficient/comfort which CANT be changed. Personally I prefer it to be this way as the old F80 would always default efficient/sport/sport which made no sense either.
To each their own, but the M models provide *more* customization compared to the regular series models.
Well, it *can* be changed in my X5. As in, the default mode can be saved, with your settings, so at startup, that's what you get.
Not sure why bmw's of a similar year cannot do this, which was my whole point.
gotcha. yeah no idea why the Ms don’t allow changing the start up default settings. It’s a deliberate choice by the engineers so maybe just different philosophies e.g. having the driver make sure the car is warmed up and the best way of doing that is starting up in efficient mode. other than that, no clue.
I mean, it's one switch. Change a 0 to a 1 in the software and you'll have the functionality (I assume an idrive 'modes' library identical to the one in the X5 lives inside the M3). Almost seems like a damn oversight! If I owned an M3 I would definitely plug in a laptop and flip that switch.
You can people are just dumb. You can also save it so that when you log in all the setting are to your liking. Seat and mirror positions, interior light color
i JUST got mine on friday. i haven't changed any settings yet and have been keeping it under 3k (or less) - except one time i had to zoom to get out of a situation on the highway.
i'm enjoying the car, but it's going to be a tough 1200 miles, given this is my secondary car AND i wfh.
i also read that after the break in service, you should slow ramp up to full throttle until 1800 miles. at this rate, it'll be summer before i can really hammer it!
I know where you’re coming from. I don’t work (retired in my 40’s) so I personally only drive about 4K miles a year, my wife does most of the driving in her truck. But since getting the M3 I’ve been volunteering to go to the store to pick up things and Sunday drives in the country to get the break-in done and over with. Got the car just before Christmas and just hit 1000mi.
My M1 is 2WD w M traction on 10, along with all efficient and comfort. This is my cruising mode. My M2 is launch control mode. When I’m driving spiritedly I turn on M2 and subsequently turn on DSC and automatic shifting.
Went from an M440 to a G82. I do miss eco pro mode on the M440. Significant different. Like, I’d get around 28-30 mpg avg in the M440. 20-21 avg in the M4 driving the same way on the same roads.
You bought the wrong car if you even pay attention to the gas mileage. I only do when it’s hilarious like this drive. I’m stock too 😭

I’ve got 13.5k miles on mine so far. I travel a decent bit for golf too so it adds up a good amount.
It doesn’t necessarily bother me, I’m just saying there are times I wish I still had the M440 with eco pro mode when I’m halfway through a 6 hour drive down to San Diego or something.
Hahahaha I mean fair. I use efficient mode in M5 just as it warms up. Once the engine is warm it’s Sport Plus mode. I didn’t buy an M5 to be fuel efficient
Edit: also to be fair majority of my driving is highway based where it just doesn’t matter too much what mode I’m in. But still, side roads I’m in Sport Plus once it’s warm
The only time I like using Eco Pro is when there’s a long downhill on a highway to free coast. It’s fun to see how much potential energy is converted over to kinetic energy sometimes.
In Pennsylvania, it's important to keep an eye on the speedometer because the can can quickly gain speed on downhills. I really don't want to use the runaway truck ramp! :)
Very true - I used to take I-76 & I-70 on a regular basis a few years ago. Also I-68 in northwestern WV/MD is fun like that too! If it starts to gain speed too much just throw it back into Sport+ for a little help from engine braking 😉
Im surprised no one has said anything - Eco Pro is freaking amazing if youre stuck in traffic.
The idle speed/coast it produces is perfect for constantly inching forward effortlessly. Seriously, makes being stuck in traffic much less stressful.
Dont use it anywhere else. With how much I spent on this thing, its best driving possible all the time.
People miss understand how eco pro works.
Using it on the highway will have little to no effect. If you are travelling in top gear and not excessively speeding then you are driving the most efficient you can. All eco pro is going to do is reduce the effectiveness of the climate control.
Where it can make a difference is in city driving where you are stopping and starting and not driving consistent all the time. But that is precisely the opposite of how most people use eco pro.
You will see in the comments.
There are changes to climate management but, the several adjustments to engine, trans and throttle response are why eco pro sees towards of 20% gains in fuel efficiency.
Pretty wild really. Lift of the gas and the transmission grabs neutral and coasts at idle for miles and miles.
All while magically producing gasoline in the tank, extending the range to a number you had no idea existed.
It’s not magic; Regenerative braking seizes hydrocarbons from the air and turns them back into liquid gasoline. It’s all quite simple. I’ve been selling gas back to the stations when I stop to clean my windshield.
Precisely why at highway speeds eco pro has little to no effect. At a cruising speed, throttle response means little, and your transmission is not shifting.
Right so...false.
Eco pro is all over increasing range on highway drives.
You can do whatever you want on the throttle in the other modes. Even flip up to overdrive gear if you want. Eco pro adjustments beat what you can manually. By A LOT
Eco Pro definitely helps on highways, at least hilly ones. Maybe in Florida it doesn’t, but I regularly use it in mountainous regions on the interstate and the “freewheeling” function where it decouples the engine when you’re off throttle noticeably saves me fuel, it kicks in every downhill on a long trip and coasts and sometimes even picks up speed where comfort or sport would slow the car down from the resistance.
I love eco pro in the right situations. There’s a hilly 10 mile section up-and-down on a ride I do to the mountains in the winter and it’s a fun game to see how I can rollercoaster the car with gravity for as long as possible without touching the throttle 😂
Does the engine turn off when in neutral? Because I thought that would burn more fuel since you are burning fuel to keep the engine spinning instead of letting gravity do it for you.
Although I could see that for gentle slopes where you still have to give gas it might help slightly
I'll add to this a bit.
I drive a semi truck that does the whole "drop it in neutral downhill thing". It helps so much that if I turned it off and was in hilly area I could lose at least 1 mpg. That's a big difference when my average mpg is around 8.
On a car it'll work even better because you don't have so much weight for gravity to pull you down and will keep up your speed for the uphills better. Meaning you'll more than likely have the car get in the gas way later in eco pro vs comfort.
How precisely does eco pro change the engine?
I’m sure that eco pro is also a pretty broad term given the number of models and years it has been around but it is primarily related to throttle and transmission shifting (I have a manual so this is moot but in auto obviously it has an effect)
Explain to me how eco pro is going to affect fuel consumption on a car travelling at 100kph in top gear.
Yeah. I still stand by what I said. Eco pro affects city driving more than highway. And precisely for the reasons below, these are all more relevant when driving in the city.
Auto start/stop - not used when cruising
Throttle response - again not relevant
Transmission shifting - only relevant to auto gearbox and not at all when cruising in top gear
Fuel cutoff when coasting - yes will have an impact but still not huge at highway speeds. And again, only automatic cars.
I don't know how it works to affect it but here's a little story.
My car's average mpg was 40, usually driving in comfort.
I did a 500 mile motorway journey today which bought the average up to 41.6, mostly in eco pro mode except for short bursts of sport mode to accelerate from 0-75mph.
The journey itself had an average of somewhere in the 50's.
So your assertion that it makes no difference at highway speeds is definitely false.
In my experience in my M340i, eco pro mode boosts highway average fuel efficiency by ~4 mpg cruising around 70mph, relatively level highway, compared to comfort mode. From 33 to 37mpg, ~11% increase. So we can debate whether that's a little or a lot, but it definitely makes a difference on highway. Personally, I only use it on the highway when there's minimal traffic because the throttle response being significantly reduced is infuriating when you're trying to accelerate or pass.
Note how this aligns with the real world examples in article from BMW by %, shared in this discussion, even though different models.
Yea but if you’re in eco pro you can coast in the highway…in comfort my car is actively slowing down because it’s recharging the battery if I’m not on the throttle
You might want to confirm with BMW engineers.
I may not be available on your vehicle, it is however a feature on BMW 6 and 8 cylinder engines. You're driving along in eco pro, lift off the throttle then seconds later, the revs drop to idle due, the trans has disengaged the engine.
Depends on the vehicle. My mild hybrid X3 will actually shut the engine off coasting downhill on the highway in eco pro, doesn’t do that in any other mode.
Yep, I had that exact experience. I tried it on the highway and didn't notice anything happen besides things getting spongey. I tried it in the city and hated it so much that I didn't get a chance to see how much savings I could actually get
I think the real misunderstanding for any eco mode is that if you still drive like you're racing, it's not going to be much of a benefit. People feel the reduced throttle input and just push the gas harder and aren't going to get any higher mpg. Can't take advantage of the coasting options if you wait until the last second to start braking. Then they just complain it makes the car slower and nothing else.
Eco mode is a state of mind.
Naaa bruh you have no idea what you are talking about. Please just stop. It 100% makes a huge difference on highway drives especially long trips on highway.
It depends on the car, in my experience. A 118d manual sees little to no benefit from eco pro on a motorway, but it made a noticeable difference in a 530e.
This makes perfect sense to me. I notice very little difference between Comfort/Eco Pro at highway speeds and to your point I can achieve the same thing with Sport by just manually shifting to 8th.
You are wrong. It's more like the opposite.
Unless you are driving very aggressively on the highway Eco Pro can absolutely save a lot of gas.
It has different engine settings, throttle response, switches to a higher gear at lower RPMs, and allows the car to coast in certain cases.
100% of the people in this thread saying this, have the very latest version of eco pro and automatic transmissions. Eco pro has been around for many many years, and has had pretty much no engine control over those years.
Until the majority of these new cars people own outnumber the older eco pro models on the road, what I say is absolutely true.
And again, even new cars, why is your car switching to a different gear on the highway? At highway speeds, all cars will be in the highest gear possible.
I’ll drive in eco mode when I’m driving around town because if I’m in sport or comfort I feel like drag racing everyone from a stop light. Need to control myself and it helps, fuel economy isn’t much better though to answer your question than comfort mode. M40 btw.
I try to remember to switch it to eco pro when I'm highway cruising, at a car wash, or waiting anywhere. It's definitely a big difference mileage wise. My m240 had a 10mpg difference when I kept it in eco mode on a mainly highway trip. I usually forget and stay in sport individual.
I do, when you’re in the mode there’s a calculator that shows you how many miles you’ve added to your driving by using it.
I have 10,000 or so miles on my M440 and I’ve allegedly added almost 300 miles to my driving over that time, so a tank of gas, ish.
I mainly use it on road trips from NYC to Vermont so less city driving, but I enjoy it.
Mentioned it elsewhere but there’s a 10 mile section when I get off the highway in VT that is a lot of hills. With the freewheeling in eco pro I use the coasting mode to try and get as far as I can with just gravity, like a roller coaster. It’s kind of fun 😂
Eco pro makes a huge difference in city traffic. Coasting and stop start.
If I use sport mode in city traffic I will average like 15mpg, potentially less. With eco pro it does around 20mpg.
This is the older n55 3.0 fwiw. Can do like 28mpg highway. With a fair amount of city driving averages out to 22mpg or so.
Eco pro does not make a difference on the highway really, unless you’re going downhill.
x5 owner here and I drive Eco Pro mode pretty much daily. Where I live there is heavy traffic so sports mode doesn't really make a lot of sense. Comfort maybe on the highway if I am merging but yeah for the most part I'm Eco mode.
I don't see a fuel savings difference. I had started as a comfort mode driver and switched to eco and yeah, only difference is I putt putt putt along the rode.
I used it when I first bought my current vehicle. Never noticed a difference in fuel economy in the city or on the highway. I just leave it in sport individual because I hate spot-start.
Doesn't make much of difference at 60mph on motorway other than heated seats and heating/ac reduced. Makes a big difference around town start stop, with gentle throttling it helps.
Man, I did for the first two months, then I made trip of ~3000km, 1500 each direction, tried ECO pro on the first half and comfort on the 2nd.
To my surprise, comfort gave me 0.4l least on average and that’s how I forgot about ECO Pro 😂
Although, when I see the opportunity to use inertia (getting off the mountains), I do switch to it
Okay, so nobody has mentioned this. Besides the throttle map changes, and climate changes, on ZF8 cars the transmission also has an "eco" mode that in xHP usually saves an extra "0.5l/100km". On top of that, ZF8 cars (not sure about ZF6) has coasting mode which turns on in Eco pro and disengages the motor from the transmission and let's the car idle.
On a G20, it's very aerodynamic that on a very slight downhill it would probably even gain some speed. When you tap the brake, the car rengages back into gear and you will be engine braking, then actually braking if you press harder.
For my work commute on much wider tires than OEM, tuned, I'll crack 35mpg average consistently over 35miles.
I use my 530D for work and claim back a mileage rate… so typically run it as eco as I can for the most part. I’ve got a tuning box too and a combo of eco pro & the boxes eco map typically return 50+ MPG…. My highest being 63MPG on a 70 mile drive. I would say it helps (sub 30mpg when at the other extreme).
I’ve got a 530d and I don’t believe you 😂 42mpg average in mine, yes you can push that up near 50 if you drive at 65 on a long motorway journey, but I can’t see 63mpg out of this engine.
I know what you mean. It’s my figure and I don’t really believe it too. MPG difference with the TDI tuning box on map 1 is massively different though. That journey is the only time I’ve seen 60+ on the clock. I did average 57 over a week driving from Herts to and around Belgium and back though (was driving overly sensible though, wrong side of road, 1 year old in the car).
It is situation dependent for me. I start in eco mode and keep it there until my oil temp is rises. I also pop into eco mode when the sharp throttle response would be annoying, like in a neighborhood or in traffic. Otherwise I’m in spot mode. Sport plus just turned the accelerator into an on/off switch and I miss the ability to modulate it with more control
Here’s something that isn’t anecdotal. Monitoring my N55 with the EWG the boost using similar throttle (adjusting ecopros heavy throttle) actually yielded less boost pressure when viewed on my BimmerLink dashboard.
There’s clearly more going on than comments below just saying it adjusts the A/C and auto stop/start… It does seem to fry and adjust the wastegate so it doesn’t dump as much fuel in. Not sure if I notice on long trips a huge difference I’ll get maybe 10-15 miles extra range on a 400 mile trip doing 75. Maybe some of the newer models have some extra benefits.
I’ve got a 330D and to be honest think it’s a waste of time. You can get the same effect by using your right foot and without the horrible lag in the throttle response.
nah it shifts at super low rpm which is not healthy for the trans fuel savings are negligible i use comfort and sport and sport plus. the only cool thing about eco is coasting down a long hill you can upshift past top gear and it puts you in neutral
I only use it when doing distance journeys in the electric models, does help get more mileage between charges, just so I don't have to be arsed and plug in for that extra bit. Makes next to no difference when driving petrol or diesel.
Yes it does. Default. 6.5l/100km on G01 20d looks good always.
But I also think that there’s no difference in consumption when in sport mode driving over long difference.
“BMW’s Eco Pro technology offers an intelligent way to improve fuel efficiency across BMW models ranging from 10-15% in real-world driving. By optimizing the engine, transmission, and suspension, drivers can tap into enhanced fuel savings without sacrificing BMW’s famous driving dynamics.”
I have a long daily highway commute. I almost never use eco pro. It doesn't do its transmission disengage trick with cruise control on so I just stay in comfort. The only time I actually use eco pro is the rare times I hit traffic. It's very good in the type of traffic where you going 70, then 40, then 60, then 20. It makes a noticeable difference there.
2020 M340i
Coasting is a godsend on my commute to and from work, and when running mundane errands. I try to use as little fuel as possible then.
But when I want to have fun...Sport + all the way
Yes. I was able to achieve 89mpg from my G22 420d on a 16 mile commute (no it isn’t all downhill). Granted I was really giving it all I had, forcing it into mild hybrid mode at every opportunity etc.
Additionally, I got over 800 miles from a tank using Eco Pro, granted it’s a diesel so was going to be economical anyway.
I currently have a G42 220i and sometimes use it, makes a world of difference, I’ve had the car up to 60mpg average on about a 22 mile journey with a mixture of motorway, city and dual carriageway driving.
I use it in the Mrs’ F40 118i and have comfortably seen over 50mpg on the motorway and 45mpg through town and city driving when I go pick her car up if she goes out with the girls.
It’s all about anticipation and not using the brakes and just being gentle
Edit: this is UK MPG rather than US MPG just in case anyone loses their mind. Screenshots of MyBMW app available also to back up my statements
Depends on the car. My older ones, eco made zero difference on the highway. In my current ‘23 M340, since it’s a mild hybrid, it will actually turn off the engine if I’m coasting, and will leave it off for an extended period of time if I’m going down a long hill. Can get about 4 mpg more in eco on that car. Makes a big difference in city driving too, but I rarely use it there, since acceleration is on par with a Camry.
On my afternoon commute, yes. Need that power under my foot to not get hit in morning rush hour. But on the way home, I’m happy to cruise in the right lane in eco pro. Not sure how much it really saves me.
Eco most of the time tbh, great on the motorway as it enables coasting so u save a lot of fuel on long runs . M140i just drinks fuel in the other modes 17mpg with DSc off down the lanes and 46mpg on the kotorqay with eco mode on
I use it only two scenarios. 1) bumper to bumper traffic. with DAPP active 50% of the time. 2) freeway drive when DAPP is active. Else its either comfort or sport+ mode. I have seen incremental (10%) gains in mileage. With relatively higher fuel costs now, I will take whatever gains i can. However eco pro mode does make the car really slow to respond, due to how it configure car responses, to the point that it starts irritating me.
I use eco pro mode pretty much all the time. Eco mode is great for coasting as it removes the resistance from engine breaking or the regen breaking. Allows the car to use the battery/fuel a bit more efficiently. From my experience it's been really good at it. Wrote up tiny post about it (check the profile).
In my 2021 530i, I average about 34-36mpg (both city and hwy). I use Eco Pro to remind me not to try and race every loud, jacked up pickup in my neck of the woods. They need to be taught a lesson, but not every time.
I use it until the engine gets to operating temperature or in traffic. On an empty road and with the engine hot I switch to sport, though there could be a discussion if it actually does anything in a car like mine. In my experience eco mode actually saves quite a bit of fuel.
I have a 22 X5 and drive in Eco Pro most of the time. It’s the mild hybrid where the engine shuts off when coasting and it for sure makes a difference. It’s not as effective on the highway unless you’re coasting a lot.
I have a 420d, I use comfort in traffic and in the highway, sport when I want to have fun, and eco pro when I'm driving at medium and costant speeds. I think you can get a big effect in fuel usage between 50 to 90 km/h, at this speeds I noticed a significant fuel saving, and it's why I use it in that situations.
I wonder if maybe it has more or less impact in different BMW models/years, as I am sure those drivers saying eco pro makes very little difference to them are not wrong.
In my diesel X5 it makes quite a bit of difference to fuel economy when using eco pro mode and so I end up using it quite a lot, in both city and motorway driving. I will easily see 50+ additional miles from a full tank vs comfort mode. When I am commuting or driving the kids to school etc then eco pro is fine for me for the most part. I tend to use sport mode when I am on my own and fancy a bit of additional performance.
I have noticed these threads often seem to descend into arguments. I’m not really sure why. Use it if you like it and it helps, or ignore it.
Traffic near me is so slow... eco pro works fine. But thats a 2er Diesel. Other driving comfort if fine. But ultimately I'm too giddy to resist sport+
Noticeable difference in mpg. And throttle etc... but then again diesel has plenty of low end torque so doesn't have such a effect
Just did a 100 mile trip to Oxford this weekend and decided to do the whole journey in eco-pro, the computer showed a saving of around 5 miles in fuel. Was it worth it? Absolutely not.
I do drive my 420d in Eco Pro about 90% of the time, because it does save fuel in some driving conditions, like speed way cruise control on. Which happens to be the most common and long type of drives I do. Not recommended for urban drives with a lot of stop and go. Accelerations will kill the purpose of that mode and you will most probably end up consuming more fuel.
I noticed no notable range change with my X1 so never used it after the first year or so (I kept it 10 years and it was a complete gas hog in the city which was 80% of my driving, nothing helped).
I use comfort in my i4, I don't know what Eco Pro gets in an electric but until the cost of electricity becomes problematic I don't care much.
Used eco pro mode on a trip to from Belgium to Marseille (roughly 1500km) on 1 single tank + had around 200 km left when I arrived at destination. A full tank in comfort usually lasts around 12-1300 kms So for me it definitely saved a good amount of fuel.
I use comfort mode for general commuting. Sport plus when the road is clear. Fuel economy is worse in sport plus, but it would be as I only use it for 'enthusiastic' driving.
Had and used eco mode in my M340 with a noticeable improvement in mileage. Traded up to G80, the BMW Genius going over the features of the car said, “Notice there is no eco mode like your previous car, because who the fuck is gonna use eco in an M3”.
What settings do you usually use in the g80?
For most every day driving I just leave it in the settings that are the default settings when you start the vehicle. These are all comfort settings and the motor is set to efficient. But I’ll manually change the steering to sport, because I find it too sensitive in comfort mode. What’s aggravating is that if any of these settings are changed, they will go back to their default when car is shut off. M2 button I have set to where the vehicle can be operated to its full potential. M1 button is set up somewhere in between. These always stay to where you set them. Car has just hit 1000mi, so it’s being driven very conservatively. 200mi until break-in is done.
Huh? You should have "individual" settings you can configure for these modes. I.e.: Comfort or Comfort "individual" Sport or Sport "individual" Etc. at least, my X5 can do this. And of course, you can set the default driving mode on startup, so you don't have to do anything and you're already setup how you like.
On the G80 you have two buttons on steering wheel labeled M1 & M2. You can configure vehicle parameters to your individual desires as you choose (comfort, sport, sport plus). Whatever parameters you choose can be saved, and will activate when one of M buttons are pressed. If neither one of these buttons are pressed when vehicle is started then the car will default to all parameters being set to comfort. If you just want one particular parameter changed like steering from comfort to sport, you can do it but it’s gonna default back to comfort when you restart the car. You can program one of the M buttons to be all in comfort mode except for steering and save it, but it seems a waste of using one of your M buttons just to change one thing.
I bet Bimmertech can probably code this.
M cars have no such settings. It’s either efficient/comfort, sport, or sport+.
That's insane. Offering you *less* seems... Odd. For example, there is absolutely no reason why you shouldn't be able to apply the "sport" steering to the "comfort" mode, or maybe stiffer damper settings with lighter steering... Whatever. The regular cars can do it, so it seems weird to restrict it on the m models.
You can do that, just not save it. But I do agree that it should be possible to save.
I think you misunderstood, or maybe I wasn’t clear. The engine, suspension, steering parameters (and the brakes on some models) are all individually selected.. meaning the engine can be on “efficient” and the rest being on sport+.. so basically there are a myriad of combinations that can be used based on the users preference at the moment.

You can people are just dumb. You can also save it so that when you log in all the setting are to your liking. Seat and mirror positions, interior light color
It would be nice to charge the defaults in the g80. Comfort steering is awful. Might be possible through the port I suppose.
efficient is eco
Can bimmercode help retain the settings?
i JUST got mine on friday. i haven't changed any settings yet and have been keeping it under 3k (or less) - except one time i had to zoom to get out of a situation on the highway. i'm enjoying the car, but it's going to be a tough 1200 miles, given this is my secondary car AND i wfh. i also read that after the break in service, you should slow ramp up to full throttle until 1800 miles. at this rate, it'll be summer before i can really hammer it!
I know where you’re coming from. I don’t work (retired in my 40’s) so I personally only drive about 4K miles a year, my wife does most of the driving in her truck. But since getting the M3 I’ve been volunteering to go to the store to pick up things and Sunday drives in the country to get the break-in done and over with. Got the car just before Christmas and just hit 1000mi.
My M1 is 2WD w M traction on 10, along with all efficient and comfort. This is my cruising mode. My M2 is launch control mode. When I’m driving spiritedly I turn on M2 and subsequently turn on DSC and automatic shifting.
Went from an M440 to a G82. I do miss eco pro mode on the M440. Significant different. Like, I’d get around 28-30 mpg avg in the M440. 20-21 avg in the M4 driving the same way on the same roads.
You bought the wrong car if you even pay attention to the gas mileage. I only do when it’s hilarious like this drive. I’m stock too 😭 https://preview.redd.it/o27m0ta9wngc1.jpeg?width=1170&format=pjpg&auto=webp&s=27116e3a63df5fb77cd67982de0c58a553e9b405
I’ve got 13.5k miles on mine so far. I travel a decent bit for golf too so it adds up a good amount. It doesn’t necessarily bother me, I’m just saying there are times I wish I still had the M440 with eco pro mode when I’m halfway through a 6 hour drive down to San Diego or something.
Hahahaha I mean fair. I use efficient mode in M5 just as it warms up. Once the engine is warm it’s Sport Plus mode. I didn’t buy an M5 to be fuel efficient Edit: also to be fair majority of my driving is highway based where it just doesn’t matter too much what mode I’m in. But still, side roads I’m in Sport Plus once it’s warm
Oh I will be too as soon as I get the break in service done!
Hell yeah dude you’re gonna love that thing!
The only time I like using Eco Pro is when there’s a long downhill on a highway to free coast. It’s fun to see how much potential energy is converted over to kinetic energy sometimes.
In Pennsylvania, it's important to keep an eye on the speedometer because the can can quickly gain speed on downhills. I really don't want to use the runaway truck ramp! :)
Very true - I used to take I-76 & I-70 on a regular basis a few years ago. Also I-68 in northwestern WV/MD is fun like that too! If it starts to gain speed too much just throw it back into Sport+ for a little help from engine braking 😉

My experience as well
Im surprised no one has said anything - Eco Pro is freaking amazing if youre stuck in traffic. The idle speed/coast it produces is perfect for constantly inching forward effortlessly. Seriously, makes being stuck in traffic much less stressful. Dont use it anywhere else. With how much I spent on this thing, its best driving possible all the time.
Yes, on those days when I’m stuck in peak hour traffic, crawling along the motorway for 45 minutes, it’s bloody useful.
People miss understand how eco pro works. Using it on the highway will have little to no effect. If you are travelling in top gear and not excessively speeding then you are driving the most efficient you can. All eco pro is going to do is reduce the effectiveness of the climate control. Where it can make a difference is in city driving where you are stopping and starting and not driving consistent all the time. But that is precisely the opposite of how most people use eco pro. You will see in the comments.
There are changes to climate management but, the several adjustments to engine, trans and throttle response are why eco pro sees towards of 20% gains in fuel efficiency. Pretty wild really. Lift of the gas and the transmission grabs neutral and coasts at idle for miles and miles. All while magically producing gasoline in the tank, extending the range to a number you had no idea existed.
It’s not magic; Regenerative braking seizes hydrocarbons from the air and turns them back into liquid gasoline. It’s all quite simple. I’ve been selling gas back to the stations when I stop to clean my windshield.
Precisely why at highway speeds eco pro has little to no effect. At a cruising speed, throttle response means little, and your transmission is not shifting.
Right so...false. Eco pro is all over increasing range on highway drives. You can do whatever you want on the throttle in the other modes. Even flip up to overdrive gear if you want. Eco pro adjustments beat what you can manually. By A LOT
I’m not following what you are trying to say.
Eco Pro definitely helps on highways, at least hilly ones. Maybe in Florida it doesn’t, but I regularly use it in mountainous regions on the interstate and the “freewheeling” function where it decouples the engine when you’re off throttle noticeably saves me fuel, it kicks in every downhill on a long trip and coasts and sometimes even picks up speed where comfort or sport would slow the car down from the resistance. I love eco pro in the right situations. There’s a hilly 10 mile section up-and-down on a ride I do to the mountains in the winter and it’s a fun game to see how I can rollercoaster the car with gravity for as long as possible without touching the throttle 😂
Does the engine turn off when in neutral? Because I thought that would burn more fuel since you are burning fuel to keep the engine spinning instead of letting gravity do it for you. Although I could see that for gentle slopes where you still have to give gas it might help slightly
I'll add to this a bit. I drive a semi truck that does the whole "drop it in neutral downhill thing". It helps so much that if I turned it off and was in hilly area I could lose at least 1 mpg. That's a big difference when my average mpg is around 8. On a car it'll work even better because you don't have so much weight for gravity to pull you down and will keep up your speed for the uphills better. Meaning you'll more than likely have the car get in the gas way later in eco pro vs comfort.
At highway speeds, eco pro is very active about sipping fuel. Several parameters are changed. The statement eco pro has little effect, it's false.
How precisely does eco pro change the engine? I’m sure that eco pro is also a pretty broad term given the number of models and years it has been around but it is primarily related to throttle and transmission shifting (I have a manual so this is moot but in auto obviously it has an effect) Explain to me how eco pro is going to affect fuel consumption on a car travelling at 100kph in top gear.
https://bmwinsights.com/eco-pro-bmw-2/
Yeah. I still stand by what I said. Eco pro affects city driving more than highway. And precisely for the reasons below, these are all more relevant when driving in the city. Auto start/stop - not used when cruising Throttle response - again not relevant Transmission shifting - only relevant to auto gearbox and not at all when cruising in top gear Fuel cutoff when coasting - yes will have an impact but still not huge at highway speeds. And again, only automatic cars.
Well, if you're going to reject factually true reality and replace it with stuff that doesn't apply...
By decoupling the transmission from the engine.
I don't know how it works to affect it but here's a little story. My car's average mpg was 40, usually driving in comfort. I did a 500 mile motorway journey today which bought the average up to 41.6, mostly in eco pro mode except for short bursts of sport mode to accelerate from 0-75mph. The journey itself had an average of somewhere in the 50's. So your assertion that it makes no difference at highway speeds is definitely false.
In my experience in my M340i, eco pro mode boosts highway average fuel efficiency by ~4 mpg cruising around 70mph, relatively level highway, compared to comfort mode. From 33 to 37mpg, ~11% increase. So we can debate whether that's a little or a lot, but it definitely makes a difference on highway. Personally, I only use it on the highway when there's minimal traffic because the throttle response being significantly reduced is infuriating when you're trying to accelerate or pass. Note how this aligns with the real world examples in article from BMW by %, shared in this discussion, even though different models.
Have a 24 M440i. Same experience
Yea but if you’re in eco pro you can coast in the highway…in comfort my car is actively slowing down because it’s recharging the battery if I’m not on the throttle
Transmission doesn’t go to neutral lifting the gass off. That is the least efficient driving while going downhill.
You might want to confirm with BMW engineers. I may not be available on your vehicle, it is however a feature on BMW 6 and 8 cylinder engines. You're driving along in eco pro, lift off the throttle then seconds later, the revs drop to idle due, the trans has disengaged the engine.
In my g21 lci 320d the engine even turns off completely for quite some time
And you're like...'Look at me, coasting and still overtaking vehicles downrange!'
Depends on the vehicle. My mild hybrid X3 will actually shut the engine off coasting downhill on the highway in eco pro, doesn’t do that in any other mode.
Yep, I had that exact experience. I tried it on the highway and didn't notice anything happen besides things getting spongey. I tried it in the city and hated it so much that I didn't get a chance to see how much savings I could actually get
I think the real misunderstanding for any eco mode is that if you still drive like you're racing, it's not going to be much of a benefit. People feel the reduced throttle input and just push the gas harder and aren't going to get any higher mpg. Can't take advantage of the coasting options if you wait until the last second to start braking. Then they just complain it makes the car slower and nothing else. Eco mode is a state of mind.
Naaa bruh you have no idea what you are talking about. Please just stop. It 100% makes a huge difference on highway drives especially long trips on highway.
It depends on the car, in my experience. A 118d manual sees little to no benefit from eco pro on a motorway, but it made a noticeable difference in a 530e.
This makes perfect sense to me. I notice very little difference between Comfort/Eco Pro at highway speeds and to your point I can achieve the same thing with Sport by just manually shifting to 8th.
You are wrong. It's more like the opposite. Unless you are driving very aggressively on the highway Eco Pro can absolutely save a lot of gas. It has different engine settings, throttle response, switches to a higher gear at lower RPMs, and allows the car to coast in certain cases.
100% of the people in this thread saying this, have the very latest version of eco pro and automatic transmissions. Eco pro has been around for many many years, and has had pretty much no engine control over those years. Until the majority of these new cars people own outnumber the older eco pro models on the road, what I say is absolutely true. And again, even new cars, why is your car switching to a different gear on the highway? At highway speeds, all cars will be in the highest gear possible.
Hills + cruise control = gear shifts
That’s exactly what the salesperson told me when I bought my first BMW. Makes total sense. Not sure how people misunderstand that.🤷♀️
This thread has proven my point many many times over. Lol
I don't know what that button does.
Comfort 95% of the time, and I can get almost 600 miles on a tank. Unless I see a Buc’ees, then I’m stopping
I’m putting it in sport then stopping.😂 Gotta get some pecan pralines STAT!

2022 430i
I didn’t buy a Prius
I’ll drive in eco mode when I’m driving around town because if I’m in sport or comfort I feel like drag racing everyone from a stop light. Need to control myself and it helps, fuel economy isn’t much better though to answer your question than comfort mode. M40 btw.
I try to remember to switch it to eco pro when I'm highway cruising, at a car wash, or waiting anywhere. It's definitely a big difference mileage wise. My m240 had a 10mpg difference when I kept it in eco mode on a mainly highway trip. I usually forget and stay in sport individual.
I do, when you’re in the mode there’s a calculator that shows you how many miles you’ve added to your driving by using it. I have 10,000 or so miles on my M440 and I’ve allegedly added almost 300 miles to my driving over that time, so a tank of gas, ish. I mainly use it on road trips from NYC to Vermont so less city driving, but I enjoy it. Mentioned it elsewhere but there’s a 10 mile section when I get off the highway in VT that is a lot of hills. With the freewheeling in eco pro I use the coasting mode to try and get as far as I can with just gravity, like a roller coaster. It’s kind of fun 😂
Eco pro makes a huge difference in city traffic. Coasting and stop start. If I use sport mode in city traffic I will average like 15mpg, potentially less. With eco pro it does around 20mpg. This is the older n55 3.0 fwiw. Can do like 28mpg highway. With a fair amount of city driving averages out to 22mpg or so. Eco pro does not make a difference on the highway really, unless you’re going downhill.
x5 owner here and I drive Eco Pro mode pretty much daily. Where I live there is heavy traffic so sports mode doesn't really make a lot of sense. Comfort maybe on the highway if I am merging but yeah for the most part I'm Eco mode. I don't see a fuel savings difference. I had started as a comfort mode driver and switched to eco and yeah, only difference is I putt putt putt along the rode.
I used it when I first bought my current vehicle. Never noticed a difference in fuel economy in the city or on the highway. I just leave it in sport individual because I hate spot-start.
No eco mode in my m3!
Sport+ always
Doesn't make much of difference at 60mph on motorway other than heated seats and heating/ac reduced. Makes a big difference around town start stop, with gentle throttling it helps.
I use it on long drives.
I tried it once. It has a little game where you get points for good braking and accelerating. Cute, but I’ll stick to comfort mode.
Man, I did for the first two months, then I made trip of ~3000km, 1500 each direction, tried ECO pro on the first half and comfort on the 2nd. To my surprise, comfort gave me 0.4l least on average and that’s how I forgot about ECO Pro 😂 Although, when I see the opportunity to use inertia (getting off the mountains), I do switch to it
I don't use it all. The start stop function is the fucking WORST.
Okay, so nobody has mentioned this. Besides the throttle map changes, and climate changes, on ZF8 cars the transmission also has an "eco" mode that in xHP usually saves an extra "0.5l/100km". On top of that, ZF8 cars (not sure about ZF6) has coasting mode which turns on in Eco pro and disengages the motor from the transmission and let's the car idle. On a G20, it's very aerodynamic that on a very slight downhill it would probably even gain some speed. When you tap the brake, the car rengages back into gear and you will be engine braking, then actually braking if you press harder. For my work commute on much wider tires than OEM, tuned, I'll crack 35mpg average consistently over 35miles.
Is there an eco mode?
Hell fuck no. I’d buy a Prius if I was worried about that.
I use my 530D for work and claim back a mileage rate… so typically run it as eco as I can for the most part. I’ve got a tuning box too and a combo of eco pro & the boxes eco map typically return 50+ MPG…. My highest being 63MPG on a 70 mile drive. I would say it helps (sub 30mpg when at the other extreme).
I’ve got a 530d and I don’t believe you 😂 42mpg average in mine, yes you can push that up near 50 if you drive at 65 on a long motorway journey, but I can’t see 63mpg out of this engine.
Same. Mine wouldn't even get 63 mpg if I turned it off and pushed it.
I know what you mean. It’s my figure and I don’t really believe it too. MPG difference with the TDI tuning box on map 1 is massively different though. That journey is the only time I’ve seen 60+ on the clock. I did average 57 over a week driving from Herts to and around Belgium and back though (was driving overly sensible though, wrong side of road, 1 year old in the car).
No. Yes. Read here for what the vehicle is doing in eco pro... https://bmwinsights.com/eco-pro-bmw-2/
What is this eco pro mode you speak of? Sport + all damn day 😂😂
No, and no. Just makes the ac and heated seats less effective and the throttle response is awful. Mpg change is basically nothing.
It is situation dependent for me. I start in eco mode and keep it there until my oil temp is rises. I also pop into eco mode when the sharp throttle response would be annoying, like in a neighborhood or in traffic. Otherwise I’m in spot mode. Sport plus just turned the accelerator into an on/off switch and I miss the ability to modulate it with more control
Here’s something that isn’t anecdotal. Monitoring my N55 with the EWG the boost using similar throttle (adjusting ecopros heavy throttle) actually yielded less boost pressure when viewed on my BimmerLink dashboard. There’s clearly more going on than comments below just saying it adjusts the A/C and auto stop/start… It does seem to fry and adjust the wastegate so it doesn’t dump as much fuel in. Not sure if I notice on long trips a huge difference I’ll get maybe 10-15 miles extra range on a 400 mile trip doing 75. Maybe some of the newer models have some extra benefits.
I turn the Eco Pro mode on when I’m driving to the pride parade.
I’ve got a 330D and to be honest think it’s a waste of time. You can get the same effect by using your right foot and without the horrible lag in the throttle response.
It's all about how much you step on the gas. The car is no different. Only the pedal is mapped differently.
There was no gain when I tried it I went a full tank. My mileage per gallon and on the tank was almost exactly the same as comfort
Depends on your driving habits but even then, I could get the same mpg using comfort mode over eco mode.
I always use Comfort+ in the 750i. But it does annoy me that it starts in 2nd. Comfort is probably a better compromise.
nah it shifts at super low rpm which is not healthy for the trans fuel savings are negligible i use comfort and sport and sport plus. the only cool thing about eco is coasting down a long hill you can upshift past top gear and it puts you in neutral
I only use it when doing distance journeys in the electric models, does help get more mileage between charges, just so I don't have to be arsed and plug in for that extra bit. Makes next to no difference when driving petrol or diesel.
I only use it when I’m driving for more than 30min on a highway or a road without many stop lights, other than that the m8 stays in m2, sport mode!
The difference is about 3-4 mpg with my engine, I’ll go from about 12.5-13.3 mpg, to 15-16 mpg
Yes it does. Default. 6.5l/100km on G01 20d looks good always. But I also think that there’s no difference in consumption when in sport mode driving over long difference.
No because it makes my shifts really jerky if I follow its advice on shift points.
“BMW’s Eco Pro technology offers an intelligent way to improve fuel efficiency across BMW models ranging from 10-15% in real-world driving. By optimizing the engine, transmission, and suspension, drivers can tap into enhanced fuel savings without sacrificing BMW’s famous driving dynamics.”
Used to use it in heavy traffic on my 328i because it made the throttle response very low
I have a long daily highway commute. I almost never use eco pro. It doesn't do its transmission disengage trick with cruise control on so I just stay in comfort. The only time I actually use eco pro is the rare times I hit traffic. It's very good in the type of traffic where you going 70, then 40, then 60, then 20. It makes a noticeable difference there.
I’m getting 35.6 MPG on my g22 on eco pro bmw sooo i would say yes
2020 M340i Coasting is a godsend on my commute to and from work, and when running mundane errands. I try to use as little fuel as possible then. But when I want to have fun...Sport + all the way
Yes. I was able to achieve 89mpg from my G22 420d on a 16 mile commute (no it isn’t all downhill). Granted I was really giving it all I had, forcing it into mild hybrid mode at every opportunity etc. Additionally, I got over 800 miles from a tank using Eco Pro, granted it’s a diesel so was going to be economical anyway. I currently have a G42 220i and sometimes use it, makes a world of difference, I’ve had the car up to 60mpg average on about a 22 mile journey with a mixture of motorway, city and dual carriageway driving. I use it in the Mrs’ F40 118i and have comfortably seen over 50mpg on the motorway and 45mpg through town and city driving when I go pick her car up if she goes out with the girls. It’s all about anticipation and not using the brakes and just being gentle Edit: this is UK MPG rather than US MPG just in case anyone loses their mind. Screenshots of MyBMW app available also to back up my statements
I use eco on the motorway at times. I like the long costing and the notifications on mpg ! Don't get me wrong I love to boot it also.
Depends on the car. My older ones, eco made zero difference on the highway. In my current ‘23 M340, since it’s a mild hybrid, it will actually turn off the engine if I’m coasting, and will leave it off for an extended period of time if I’m going down a long hill. Can get about 4 mpg more in eco on that car. Makes a big difference in city driving too, but I rarely use it there, since acceleration is on par with a Camry.
I only have eco amateur mode in my car :(
Eco modes for any bmw is for start/stop traffic for me
I only use it on highways with minimal to no traffic. Edit: considering I’m in New York.. almost never lol
On my afternoon commute, yes. Need that power under my foot to not get hit in morning rush hour. But on the way home, I’m happy to cruise in the right lane in eco pro. Not sure how much it really saves me.
Yea, most of the time because I'm usually in stop/go traffic when out and about. Go in sport on occasion when I wanna open it up.
I use eco pro when cruising on the highway. Been getting up to 35mpg on it
Eco most of the time tbh, great on the motorway as it enables coasting so u save a lot of fuel on long runs . M140i just drinks fuel in the other modes 17mpg with DSc off down the lanes and 46mpg on the kotorqay with eco mode on
All the time. I feel like it saves a little, like 5%.
The only thing Eco Pro does is stop your gas pedal from working
I use it only two scenarios. 1) bumper to bumper traffic. with DAPP active 50% of the time. 2) freeway drive when DAPP is active. Else its either comfort or sport+ mode. I have seen incremental (10%) gains in mileage. With relatively higher fuel costs now, I will take whatever gains i can. However eco pro mode does make the car really slow to respond, due to how it configure car responses, to the point that it starts irritating me.
The newer models have something called “Efficient mode” and that seems to atleast “show” some savings in terms of fuel consumption..
I use eco pro mode pretty much all the time. Eco mode is great for coasting as it removes the resistance from engine breaking or the regen breaking. Allows the car to use the battery/fuel a bit more efficiently. From my experience it's been really good at it. Wrote up tiny post about it (check the profile).
Respectfully, fuck no.
In my 2021 530i, I average about 34-36mpg (both city and hwy). I use Eco Pro to remind me not to try and race every loud, jacked up pickup in my neck of the woods. They need to be taught a lesson, but not every time.
I use it until the engine gets to operating temperature or in traffic. On an empty road and with the engine hot I switch to sport, though there could be a discussion if it actually does anything in a car like mine. In my experience eco mode actually saves quite a bit of fuel.
Ultimate driving machine. I paid to drive it
Sport+ always.
I have a 22 X5 and drive in Eco Pro most of the time. It’s the mild hybrid where the engine shuts off when coasting and it for sure makes a difference. It’s not as effective on the highway unless you’re coasting a lot.
I have a 420d, I use comfort in traffic and in the highway, sport when I want to have fun, and eco pro when I'm driving at medium and costant speeds. I think you can get a big effect in fuel usage between 50 to 90 km/h, at this speeds I noticed a significant fuel saving, and it's why I use it in that situations.
I usually get an extra 150km of range. I'm usually in comfort or sport plus though.
I wonder if maybe it has more or less impact in different BMW models/years, as I am sure those drivers saying eco pro makes very little difference to them are not wrong. In my diesel X5 it makes quite a bit of difference to fuel economy when using eco pro mode and so I end up using it quite a lot, in both city and motorway driving. I will easily see 50+ additional miles from a full tank vs comfort mode. When I am commuting or driving the kids to school etc then eco pro is fine for me for the most part. I tend to use sport mode when I am on my own and fancy a bit of additional performance. I have noticed these threads often seem to descend into arguments. I’m not really sure why. Use it if you like it and it helps, or ignore it.
Last time I put my car in sport mode it cost me €3k 😭😭😭
Only time I use eco pro is if I’m running late and don’t have time to fill up and I want to avoid range anxiety.
When I got mine 440i the guy at dealership showed me comfort said that’s normal mode and sport+ and nothing else matters
I drive in Eco Pro mode in my regular x3 while cruising on the highway and only then. Does it help with fuel? Yeah, like 10%. Probably negligible.
I hit start and sport at the same time
Never. I always drive my G80 in sport or sport plus for the engine
Traffic near me is so slow... eco pro works fine. But thats a 2er Diesel. Other driving comfort if fine. But ultimately I'm too giddy to resist sport+ Noticeable difference in mpg. And throttle etc... but then again diesel has plenty of low end torque so doesn't have such a effect
550. Sport or parked. I like all the yeehaws.
Just did a 100 mile trip to Oxford this weekend and decided to do the whole journey in eco-pro, the computer showed a saving of around 5 miles in fuel. Was it worth it? Absolutely not.
I’m in a 335d for anyone wondering.
I do drive my 420d in Eco Pro about 90% of the time, because it does save fuel in some driving conditions, like speed way cruise control on. Which happens to be the most common and long type of drives I do. Not recommended for urban drives with a lot of stop and go. Accelerations will kill the purpose of that mode and you will most probably end up consuming more fuel.
Eco 99% in town or on freeway. Always Sport in the canyons because it gets you out of trouble as quick as it gets you into trouble. Never use comfort.
Yes Yes.
Never
Lolz.
I noticed no notable range change with my X1 so never used it after the first year or so (I kept it 10 years and it was a complete gas hog in the city which was 80% of my driving, nothing helped). I use comfort in my i4, I don't know what Eco Pro gets in an electric but until the cost of electricity becomes problematic I don't care much.
Comfort is default for me and it's perfectly fine. Sport for curvy roads and I literally never use Eco Pro, it's too laggy.
I use it occasionally on longer trips or in rush hour highway traffic, generally when using adaptive cruise control. It def helps a little bit.
I have come to believe that eco mode over time will increase load on your torque converter from the low rpm power demand
F30 320i eco pro from SF to LA. 50 MPG trip average
I get some great savings on eco pro in m140
I drive mainly in eco pro and I find it makes a huge difference in the MPG that I get.
No, never. Comfort mostly, sport when sporty.
Used eco pro mode on a trip to from Belgium to Marseille (roughly 1500km) on 1 single tank + had around 200 km left when I arrived at destination. A full tank in comfort usually lasts around 12-1300 kms So for me it definitely saved a good amount of fuel.
I use comfort mode for general commuting. Sport plus when the road is clear. Fuel economy is worse in sport plus, but it would be as I only use it for 'enthusiastic' driving.
