  • The 325i (auto) I test drove today said 22-29 mpg on the window sticker. By contrast, the 650 next to it said 18-26, with it's big V8. How 'bout some real-world input from the 3-series owners?

    I'm getting 28.3 mpg in mixed (mostly city) use, which I'm exceedingly happy with.

    325i RWD, manual transmission - 25-ish in the city, a minimum of 30 on the highway.

    2006 330i auto 12k miles. Averaging 25mpg in mixed but mostly highway driving in a rather hilly area. Gets low 30s on long highway drives.

    330i, mostly highway miles in europe - 23 mpg averaging 100+ with runs above 140 for extended periods. Not bad given how hard the engine's working at those speeds.

    '05 E46 330i convertible....

    7K miles.... 22.9 MPG lifetime average in commuting/suburban driving..

    I don't get to drive it a lot... But, at steady 70 MPH speeds, it is around 29-30 MPG... Probably 15-18 MPG on grocery runs..

    I have a 2003 325i which i bought new, i have been averaging ~27-30 mpg in mixed-to-highway driving since i bought it. Very happy with the gas mileage.

    I have a 2006 BMW 325xi. For the first 4000 miles, I have been averaging 19-27 MPG. I am using nothing but premium gasoline. I wish it was better, but the car is so great that I can live with it right now.

    I've had 2 short highway trips from 27-28 at avg. speed 65-70. If you want to keep your highway mileage over 30, find a nice straight road and put the cruise on 65-70 max.

    In town, well under 20 without any agressive driving as I respect the breakin period so far. I'll post again later.

    Dont get me wrong, 28 on the hway is awesome! I love this car. We were going 90 today on I10 and when I told my wife and 12 yr old... they did not believe me. Smooth and quiet!
  • I have a 2001 330 ci, automatic with 225 h.p. It gets 18-19 mpg in city driving, including a DC commute,and 29 on the highway at 80+mpg (30 with the a/c off).

    Have a 2006 325i with manual and get about 18-20MPG in the city and about 32-34MPG on the highway. Recently drove 600 miles with a fairly big Thule box on the roof averaging 75MPH and got about 30MPG. I can consistently get about 34-35MPG on the highway if I keep it at about 55MPH. My last car was an SUV so I am very happy with this mileage.

    I've got the 330i. I get about 20 MPG in all city...23-24 MPG in mixed driving. Get about 30 MPG (cruise set on 80 MPH) on all highway.
  • I am getting about 12-14 mpg in the city, 16 - 19 on freeways. I am at 2000 miles now and the lifetime average is 16 mpg. (The EPA sticker says 19 - 27.) It's so strange to drive a car and get, like, 14 mpg, when I was really looking forward to getting in the 20's around town!

    I am disappointed to say the least. Would love to hear about other's experiences. New and after break-in. And how long was break-in?

    I am at about 60-65% of what to expect. There seems to be little I can do.

    I wish I had known this before I bought a new car sight unseen -- in my state, you sign away your rights to return the car before you drive you car off the lot. I special ordered my car through a broker. The same problem would apply to any car where you could not test for mileage on the spot before purchase, however.

    It's an agreement you have to sign, here in Cal., called, "there is no cooling off period", ie you cannot return your car even if you discover something like I did, seriously to your dislike immediately after purchase.

    I love my car in every other way. But I feel like either I was not informed of what's true about these cars, in general, or my car is an exception. At this point, I am not sure which is the case.

    In either case, personally, with what I have gone through, I would not buy a new car again, because I have learned that i have no recourse -- apparently BMW can make a car with any mileage they wish and not be legally accountable!

    Each time, I have to figure out when I want to make a trip, it's going to cost me 30 to 40 percent more in gas than I thought.

    I wish I knew what I could do. Any suggestions? Ideas would be gratefully received.

    Fuel consumption is very dependent on both traffic conditions and driving technique. That said, I'd still think that your 330ci should be getting 18-20 mpg in town and 25+ mpg on the open road- even if it's an automatic. Are you calculating fuel consumption at each fill-up or are you relying on the on-board computer? I would keep a log book or spreadsheet to document the fuel consumption. Are your tires inflated to the pressures indicated on the door jamb placard? Is the wheel alignment within factory specifications? If the car checks out OK, I'd still want to wait until your 330ci reaches @10,000 miles to see how the engine break-in affects the fuel economy- you HAVE been following the owners manual break-in procedure, correct? Some BMWs will pick up a couple of mpg(or more) once the engine is fully broken in.
  • HI, I am willing to take a driver's lesson. Tho I must say, I am a normal driver, in my opinion. How that is going to add 5 to 10 mpg to make me in normal range seems a little far fetched. And yes I did get everything checked out.

    SO thanks for your ideas...I do appreciate...

    It is unfortunate that BMW told me they refuse to stand by the car they produced.

    Would I buy a BMW again? Yes! Do i *love* my car? Yes. a new one? not a new car...especially a new BMW, never again. Wait ten thousand miles? And then what? What if then it isn't right? They've already told me they aren't going to do anyting about it.

    I have heard there are other cars out there, 330s,with this problem. I am wondering if this is an issue that goes far beyond just me?

    When I've asked the dealer and the manufacturer how many mpg the car should get, they say, they don't know. Now, do YOU believe that? I don't.

    All I can say? I would never buy a new car, especially one where I could not check the mileage first hand again, first. THere is no one to protect you or me as consumers.

    Thank you for your suggestions. I remain open minded for more ideas. Plain out of them over here and willing to try anything. I hate having to do math every time I want to take a road trip.

    Apparently you have no recourse if you get something way off the mark. A warrantee doesn't do it.

    Still would love to know what others are getting....

  • ps-- I am keeping a log... gas in, miles in and out... average miles is about 16 mpg. Exactly what it says on my nav system: lifetime mpg of 16 mpg!

    Although it is interesting to watch how the mileage counter does change when you drive, ie accelerate, decelerate, etc... .there are actually three mileage counters in my car... even one on the control panel! So I can see very well what happens every time I step on the gas, coast, brake, etc... I get a driving lesson just driving in my car on gas mileage!

    And I do mostly freeway.

    In town commuting, I get 20-22 mpg. Keep a "higher than what you would think" psi in the tires around 40psi), it makes at least a 2 gallon difference. In the winter, I get a couple less, either from gas or lower pressure in the tires for better grip. I drive all-season Michelins.
    Just finished a trip to San Diego from Colorado Springs. Interstate driving along with some city. With four in the car and luggage, with air on, and normally at about 80mph on Interstates, I got 28mpg for the 1,300 miles.
