34 MPG on 2nd tank

I just got this car and have only put two tanks of gas through it so this is really preliminary insofar as the assessment goes. But there are a lot of things I like about it, and some things I do not (the gongs-can't get rid of them, hate them). But the gas mileage in my 2014 s-drive is really excellent. First tank display readout average was 29.2 mpg. Actual mileage computed from gas pump was 29.8. So the car computer underestimated the real MPG by a small amount. This is with 90% highway miles and 10 % city.

Second tank was 95% hwy and 5% city, ave speed on hwy 74 MPH (love that cruise control-can set it within 1 mph of the usual and customary pull over and fine 75mph), AC on most of the time and added weigh of wife, Budgie bird and two suitcases and we eked out 34 MPGs on the car computer. Real world MPG based on fuel added was 33.8 MPG. Not bad!

I am impressed that the car computer is rather accurate. The MPG meter is nothing more than a vacuum guage.

I know this seems to contradict everyone else's experience with MPG but am just reporting what I am getting.

You do realize that when you set cruise for 74 in a BMW, you're probably going about 71. (Don't trust me on this--verify first with a gps, but I think that's what you'll find.)

I do not doubt this. Actual MPH was not verified and it is probably in my best interest to have the speedo make me think I am going faster than I am really going.

Congrats on the great gas mileage. I'm very jealous - getting on average around 24. I really need to stop driving so aggressively. And perhaps move to an area that is less hilly.

One word of caution - you should not be using cruise control during the break-in period. The engine wants varying RPMs to help with the break in and you are not going to get that with cruise control. Also, the cruise control isn't smart enough to keep it below 4,500 RPMs if it needs to climb a steep hill or accelerate quickly.

How was that MPG calculated? Where did the figure come from?

+ It varies a bit car to car, and on my BMWs it's been a bit of a sliding/percentage so the error is smaller at lower speeds. GPS is the best way to verify. Don't forget it changes depending upon the tires (re-verify if you put winter tires on).

The error is intentional (due to some EU/US regulations), your dealer can't correct this.

BTW, the odometer is usually dead-accurate, and there is some coding you can do to get the "real" speed displayed.

Mileage divided by gallons pumped starting with a full tank.

Let me add something. If you have ever used a Scan Gauge is gives you a fairly precise way of knowing where the best fuel efficiency is. These little gadgets are kind of fun if you do not mind the nerd factor. They plug into the car under the dash as you know.

Most if not all of my driving is done in the manual mode because I find the transmission shifts into high too soon for my liking. Driving in 7th or 8th gear below 1500 rpms is less fuel efficient if you put any load on the engine than using a lower gear, which is to say 5th or 6th gear at 2000 RPMs is more fuel efficient than 8th at 1300 or 1400 rpms (according to the scan gauge). I also wonder if it is hard on the engine, accelerating in a higher gear at 1300 or 1400 rpms. I don't do it.

Using the ASS does not save much fuel by my calculation.

Edman is right about the cruise control, probably not a good idea to use it this early on. I just got lazy.

When you say any load, does that include your highway cruising/speed maintenance load, or are you just referring to acceleration?

I have found that while the analog spedo reads high, the digital cruise control display is pretty accurate on my vehicle.

Maintenance load and light acceleration below 1500 rpms in the higher gears, 7th and 8th. But let me qualify that this observation is really hard to infer from the Scan Gauge data because any light acceleration decreases the MPGs real fast, just as it does with the vacuum gauge on the display. And...it is probably very close, but the higher RPMs seem to have slightly better fuel mileage vis--vis the scan gauge.

I have done these comparisons extensively on my other car, an '02 Toyota Rav4 which has the gauge permanently mounted on the dash. It has a manual transmission and if you accelerate in a higher gear below 2000 rpms the mileage drops off considerably vs 2500 rpms in a lower gear. But this car does not have a turbo and it is revving 3000 rpms at 65 mph, much higher than the X1, as it is designed to be.

I might add it is very impressive to me that a car with twice the HP, weighing 500 pounds more and having an auto transmission gets better gas mileage than my manual Rav4.

Just a quibble. I have seen several references recently to the mpg gauge being a vacuum gauge. I doubt that very seriously. It's pretty much useless, I agree, but I'm almost certain it's based on a computerized signal related to actual fuel consumption.

Do you have a picture showing your Scan Gauge setup in the X1? Curious to see how it looks on the dash or console.

If it was a computed readout it would read 0 MPG at idle. I do not think it does that.

I do not have the gauge mounted in the X1, the console and dash look too nice to clutter up with gadgets. I do have one mounted permanently in my other car, a RAV4.

Actually, what it does is swing all the way to the left at idle. If you watch it, as you brake, you may see it swing to the right and as you approach 0 mph all of a sudden it swings all the way the left. Here's something to try--give it a little gas when stopped with your foot on the brake and see what happens. If it were a vacuum gauge, it would move. I will try to remember to give this a try.

34 MPG on 2nd tank

I noticed this for the first time today. I was driving with some ASS and while stopped it swung all the way to the left.

If I recall correctly without any ASS it swings right.

I guess the bottom line is you can swing either way depending how your ASS looks. (No puns intended...ok maybe one of them)

Mein Auto: 2014 x1 28i
I have had my 2014 X1 for about a week and a half now. Yesterday i took it for a long drive. Not a road trip by any means, but a nice 386 mile round trip. Road conditions were good, no rain or heavy winds and relatively flat. I set the trip computer at the start and at the end, it registered 32.3mpg. Gas tank took 11.8 gallons with a couple extra clicks. 386 / 11.8 = 32.7. I am pleased with the result. Yes, i had to be conservative to get it..but those numbers were not achieved by the EPA while having fun, however, it is possible get the result. Your results may vary!

Mein Auto: 2013 335i xDrive
I have just completed a 900 mile drive through northern Italy on a 2014 X1 X drive 28i (dropped it off in Munich yesterday) and found that at 80+ mph which is very easy to do on the Italian auto routes I was getting just under 25 mpg (about 24 mpg. on the German autobahns at higher mph) I had expected somewhat better mileage since I also have a 335i Xdrive which we drove for 1400 miles through Germany, Latvia & Lithuania last September. It did 29+ mpg on similar roads. I am attributing the lower mpg to the X1's higher ground clearance. I hope that the X1 improves when we get it home and drive at slower speeds. On a happier note, the X1 handling was superb.

Lucky you! My X1 X drive 28i gives 26mpg on freeways (2200mi driven in 1 month)

My combined comes around 22-24. Any tips???

I have filled my 2013 328i (6 speed plus optional sport suspension) twice since buying it and have averaged just over 29MPG (Imperial) in fairly spirited city driving. I always drive with the sports setting engaged and the Start/Stop feature off. I haven't had a chance to do any extensive highway driving as yet. I think that this works out to just over 24MPG (U.S.). Are these numbers typical?

Two more fillups with the identical results - 29MPG~. I'll be doing some highway driving next week and will see how I do then. Hoping for 40MPG~!
