The X1's Gas Mileage (ECO PRO vs. Normal mode)

Good Morning/Afternoon/Night my fellow BMW siblings.

Hope everyone is having a good day/evening/night

The topic i have today, is the X1's gas mileage.
According to the EPA, the S-Drive 28 model is rated at 23 city and 34 highway.
I believe the X-Drive model loses 1 MPG on both, not much of a sacrifice for AWD.

For the past 5 months that i have owned my X1, i have noticed that my average MPG is around 20 MPG, with 90% of it being stop and go city traffic.

I recently took a trip to see my brother in San Diego. I was driving around 70 MPH and i had no traffic what so ever. i was mainly driving in ECO PRO and watching those "Extended Range" miles just rack on up.

Upon returning back to L.A., i had racked up 50 miles of extended range and i was in the MPG range of 24.5 miles to the gallon. Rather disappointing, considering the X1 is rated to achieve up to 34 on the highway.

i would say that 95% of the time i am always driving in ECO PRO mode, even in the city. I would get as much as 11-14 Miles of extended range when i would drive in the ECO PRO mode. Problem started to arise when I started to not like the feeling of the car struggling to get up to speed, mainly because of throttle response to be similar to a Prius. (No offense to Prius owners out there)

Anyway, upon further inspection i started driving in the normal mode, and soon came to realize that my car is getting much better MPG than in ECO PRO mode

I think i stumbled upon a post on this forum, and someone said that it is better to drive the car in normal and get up to speed, then making the car struggle to get up to speed due to the lack of response of the throttle.

Typically in cities, the average speed limit is usually between 30-40 MPH. I noticed that once i get up to speed, much faster due to more response, the needle that displays my instantaneous MPG, now typically stays between the upper 50's and the 30's, when i am casually driving and or coasting. I like to assume that if you keep that needle out of the 20 range, than your average MPG would go up, and sure enough, i was correct

So i went from 20.3 MPG to a now whopping 22.3 miles to the gallon, and let me remind you that I drive in a lot of stop and go city traffic with auto start/stop enabled.

Thus i have proven, at least for my X1, that normal mode is better for city driving, in both performance and MPG. ECO PRO is better suited for freeway driving, as proven when i drove to San Diego and i got 50 Miles of Extended Range.

I would like to hear if anyone else has played around with the X1's driving dynamics and what MPG do they get?

The reason i am sharing this article is to see if anyone else can relate when driving in ECO PRO vs. normal. I know that there are some MPG forums out there, but I am just curious to see what other people experiences are.

Thanks for reading



BTW, my car's name is Elliot, so if by chance you are wondering who Elliot is? It's my X1 HAHA

Interesting post, thank you.
I wouldn't be surprised that ECO PRO does not bring anything in city. It makes the engine too unresponsive and therefore not only you tend to push it more and more and more, but it finally switches 3 gears down and accelerate lik you didn't want to..
I just got my car 2 weeks ago, so I have no figures to report yet, but I'm starting a new excle file i'll report results here.

I personally do a lot of city driving, so the ECO PRO option does not do much for me, if anything. I save maybe ~5-10 miles per tank by leaving it on. The Start/Stop function is useless to me here based on the amount of "Rolling" stops everyone does here in my area. I've found that, due to local traffic patterns, I often have to brake hard and accelerate hard in order to mesh with other vehicles. There's nothing economical about New York driving.

I've only owned the vehicle for a couple months, but to contribute to your post, here are some concrete numbers that I've obtained from my first 5 Fill-ups. I track this stuff religiously.

2014 X1 28i (AWD) I pretty much drive like a grandma. I do not have any engine modifications (At this time)

Total Miles per Tank of Gas (Miles Actually Traveled plus Miles Remaining on dash)
Fill-Up 1: 362
Fill-Up 2: 371
Fill-Up 3: 381
Fill-Up 4: 372
Fill-Up 5: 364
Average : 370 Miles Traveled per tank of fuel

Miles Traveled per Gallon
Fill-Up 1: 22.63
Fill-Up 2: 23.76
Fill-Up 3: 24.41
Fill-Up 4: 25.14
Fill-Up 5: 24.82
Average: 24.15 MPG

Gallons required at Fill-up
Fill-Up 1: 16.00
Fill-Up 2: 15.62
Fill-Up 3: 15.61
Fill-Up 4: 14.80
Fill-Up 5: 14.67
Average: 15.34 gallons required per fill-up

Hope this info helps.

An extra piece of info, if it helps anyone. I live roughly 7 miles from my work. I work 5 days a week. I do not drive a ton aside from going to work, but I do go shopping a couple times a week, play sports three nights a week, go to dinner a couple nights a week. Here is how many days I go between refueling:
Fill-Up 1: N/A (Car was new to me)
Fill-Up 2: 17 days
Fill-Up 3: 14 days
Fill-Up 4: 19 days
Fill-Up 5: 17 days
Average: 16.75 days traveled between fill-ups

Ok, I changed the metrics in my car to make it easier to compare with you :-)

I don't think I will be anywhere close to you.

It went up to 35.4 mls...:






...but then huge traffic jam to go back home and 17 mls...





I live in mountains so it is unlikely that I can do much better.

That said I am doing 31 mpg.

Cheers

I can't peg the cars mpg display to any of my driving. It's worthless.

So is Eco Pro and ASS.

I can idle without AC on for 4 hours to use one gallon; .25 gph on guage.

I use a scanguage, and on a 408 mile segment last month at 70 mph, I used 11.85 gallons for 34.4 mpg figured with pen and paper.

On 70 miles of that segment, my scanguage said 42 mpg.

The secret was that it was good weather with almost no AC, and I had a 20 mph tailwind most of the way.

I've also driven 80 mph with headwind and AC on and gotten 23 mph.

I figure I'll average 25mpg over the life of car even with track days or driving fast.

Try to get that kind of mileage and performance out of any other car.

mileage

My '13 has been steady at an average 26.7 miles/gallon fuel consumption, letting ASS do its thing most of the time, but no EcoPro mode (I do like to accelerate with traffic, not create slow downs).

S-drive, 28i. Driving is mostly ~20 mile trips with mix of freeway and surface streets.

After about 10,000 miles the consumption settled in to what is reported above. Odometer currently 26,000+ miles.

+50 miles!? The best I've achieved is +19 around town. When I do the long commute to work on the autobahn (50 miles each way) I lose any additional miles I've "earned."


I've also learned that gas mileage drops a LOT when going from 90mph cruising to 110mph cruising.

Now try one tank driving in 'M' around town.
A few tips:
Get into highest gear ASAP
Coast in high gear toward stops

This car does not coast well in any other mode, lots of engine breaking.

If the engine breaks, you bought a Merc, not a BMW...

And you can put it in neutral for even smoother coasting.
Brake early, so your minimum speed is as high as possible, just as you start accelerating again. If you brake down to 30 as you approach a stop, and can go from a rolling 30 to 50 when the light turns green, you save a lot of gas compared to if you approach the stop so fast that you have to brake to a complete stop.

Had mines 2 weeks and I'm doing 400 miles a week to and from work.

Average MPG = 50.4 (uk gallons) which is 42mpg in american gallons.

I do have the 2L diesel x-drive though

I have a 15' sDrive28i. ~25MPG mostly highway at 80MPH.

The economy figures are calculated from air resistance, transmission loss, and rolling resistance and sustaining that load in a lab environment where the turbo hardly ever kicks in.

At 70MPH, the X1 has a drag of 470 newtons. At 45MPH, the X1 has a drag of 200 newtons. A gallon of gas has 130 mega joule which at 200 newtons, will last you about 400 miles. You take out ~80% loss via heat and within the engine (since the engine is not in the optimal efficiency range 3000-4000 RPM) and 5-10% loss between the engine and the ground. That gets you to about 50MPG which is roughly what you'll get at 45MPH. At 70MPH, some of the static losses do not scale linearly so you save some but lose out since you're expending more than twice the energy on air resistance.

Also to consider, the turbo kicks in a lot since the N20 has a small displacement and low compression ratio.

I have a 2015 X 2.8 and I drive 80/20 favoring highway driving (if you can call it that).
I average 24mpg.
No matter how I drive, whether or not I use eco pro mode, this is what I get.
The 34mpg rating is hogwash. The only way to achieve anything close to it is to not drive the car.
To be honest, it's the single most disappointing thing about this car. Otherwise I enjoy it.

The EPA city number is hogwash, we have 21,000 miles on our 2013 X1 sdrive and we are at 22.1 mpg total since purchase. 90% city and 10% hwy miles, a recent 320 mile hwy trip netted 29 mpg at about 80 so that's not terrible and if I actually drove the speed limit could probably get 30 or 31. Our city driving which is 1-5 miles trips is consistently 20.5-21 mpg and that's my wife driving fairly easy not using ECO. I see no way possible to get close to 24 in true driving of short trips so it depends on what the EPA considers "city". It has to include quite a bit of true 50-65 mph road/hwy travel of over 3-4 miles. True stop and go with stop signs and a lot of traffic lights no way.

My 2013 sDrive is at 36700 miles. I live in LA, have had a few short road trips (Palm Springs, etc). For a long time my total MPG was showing as 28. But after a long period of only city driving (which can include flowing freeway traffic), it has dropped to 27.6. When I'm doing mostly street driving, I get a tank MPG average of 24-25.

So it was those few longer road trips that got my overall average as high as it shows now, 27.6. My X1 at least must have been achieving 34 mpg during those trips.

But for now I"m trying not to recklessly pile on any more mileage. I'd like to make it to four years with 50,000 miles and take advantage of as much free maintenance as possible. I purchased it November 2012 so I've got to make it through 16 months or so on 13,000 miles...

Definitely part of the numbers depend on the terrain, LA is pretty flat compared to Columbia, SC which is mostly hills but also LA is mostly hwy driving although slow hwy driving. If I go 2-3 miles it's no true hwy and it's constant lights. So everyone is really comparing apples and oranges and we can't compare totally different areas of the U.S.

Sorry to hear about the MPG issues. I just wanted to say that I have actually experienced MPG's inline with the EPA's ratings of 23 city/ 34 highway. Typically, I drive mostly city miles with a couple of highway trips and have averaged 25 MPG overall.

Recently, I took a trip with winding roads and hills using the A/C and averaged 34 MPG, not too shabby in my book. Nothing like our TDI wagon, but we look at our little X1 as a sports car, so it's to be expected.

I have noticed that the MPG varies greatly if you use the A/C full blast and if you race to red lights. Although the EcoPro appears to have little effect. I'm still not sure about Stop/Start.
