Yes, your dealer should be able to easily recode the car so the default setting leaves ASS off. I saw many people on this forum posting that they had it done.

Far from it. The test schedules include cold and hot starts, a great deal of acceleration, braking, etc. This is why many can easily beat EPA estimates, especially in freeway cruising.

The weighting on those extreme cycles is lower than you may expect.

We had someone a month ago complaining and swearing his car was broken because he was getting 16 mpg on this new 328i. Turns out he drove 5 miles to work and sits in traffic for 30 minutes on the way
I drive 5 miles to work in LA and do not sit in trafffic. Its 10-15 mins and literally a handful of lights and a few stop sign and average 16mpg. His car must be more efficient than mine. But im not complaining. 16 is better than 12. Havent even been able to reach ONE trip that averaged me 30mpg. But 27 is super green hybridish to me. Lol.

It seems to take 10-15 minutes to get the oil temp up to normal. If all you are going is 10 mile trips, you car is never getting fully warm and stabilized.

Take your car out on the open road and let it breath properly as suggested and see what it will do MPG wise.
Yeah andy fisher. Come to the track and let it breathe. You wont complain about your 16mpg after that session lol.

It sounds like people are mixed on how their own 328i's are doing with fuel economy.
But I can't imagine that our driving styles are THAT different.
There are many different driving styles!! You know the guy who is pissed and honks at everyone and tries to go fast in traffic by swerving in and out of traffic? (Im not that guy). Or the guy who quietly finds his way quickly through traffic? Or (dreaded) the dude who is causing traffic by going extra slow. Or the (even worse) guy causing traffic IN traffic?! Ha.

I absolutely regret my decision to buy my 2013 328i. I am getting 12 mpg in my 5 mile city commute to work. I got better than that in my previous car, a nine year old Lexus SC430 that I absolutely loved. Worst decision of my life.

Are you flooring it in between lights? I was averaging 25 on my 5 mile city commutes in Comfort.

My dealer will still only code to 'Last Setting'. I drive often in Eco Pro which renders that default of little use to me. Starting to think I should buy a coding kit for myself.

When AC is a necessity (Texas summers, yo!) ASS becomes completely impractical. AC ensures the engine will resume within 30 seconds of shutting off.

No I am a very careful driver. I drive in comfort mode. I watch the eco gage under the speedometer all the time and try to ease on the gas so it doesn't drop below 10mpg for very long. I have not tried the actual eco mode yet. I do have the engine start/stop on and it does turn the engine off at lights. I was so looking forward to getting better mpg then I had before.

Yeah, that can be frustrating, though 12 is hard to picture unless you're just in a constant state of stop'n'go.

My advice: Put away your MPG trackers and just drive your car however you want. The MPG tracker for me was like a leaderboard - I needed to beat my last high score. Once I let that go, my fun factor immediately improved.

City commutes can be tough on a car. 12 mpg is conceivable if you are just idling and going nowhere or accelerating from light to light.

Have you gotten the car out on the highway on a longer trip with a mix of driving? If its not over 20+ on the highway, there is a problem.

Traffic jams and short cycles are a mpg killer, obviously. The consumption can be worse by 20-25% in my own experience and it just falls out of EPA range. After 7000miles, the engines on our Honda loosened a bit and fuel economy improved significantly. It takes time.

Thank you for the reply. Yes your description of my commute is very accurate. I have done a small amount of highway driving and the mpg is much better. Unfortunately I live in a very urban area and hardly ever get on the highway. I'm just now glad to know that 12 mpg is not a defect.

I think it was just the shock of the low mpg that has me freaked. I'm going to try the eco mode at some point too. Hopefully like you say the mpg will improve slightly with time. I'm determined to get it at least above my last car. Thanks

Been there, done that. They might have to keep your car for a day as they have to get the ok from BMWNA. Any software upgrade will most likely be done at the same time.

I've had a 328i loaner for over a week now and I'm getting worse gas milage than I get normally in my 335. I'm getting about 16-17mpg in the 328 while I get about 18-19 in my 335. Yeah that's New York traffic for you.

About 1200 miles or so on my 328xi thrasher - I am impressed....I have been averaging 25 - 28 mpg on my 25 mile commute to DC and this weekend I did a quick 200 mile sprint up 95 and averaged 40 mpg when cruising between 65 - 70 mph and dropped to 38 mpg at higher left lane speeds. Just incredible to see miles-to-empty increase the further I go..... this is a very different experience than my M3.

I get about 26 mpg on my daily commute, which is about 5 miles of Southern California city driving and 10 miles of open road with little traffic. On a recent 3000+ mile road trip I averaged between 32 and 33 mpg.

HAHA yes in my M3 it will say 50 miles to go and then 3 miles later say 38 miles to go.

but honestly I never leave the dash showing on that - I always have it set on the oil guage. More important and I get around 180miles per tank. Sounds about right.

I'm getting about 18.5-19.0 mpg's on my 2007 328i. It has about 51K miles.

I live in the South Bay area and have a lot of frequent stops.

I guess there are certain things we can do to get the most mileage.

1)make sure car is tuned up, oil change, etc.
2)proper tire pressure
3)proper wheel alignment.

I agree, even in my 320i, on cruise im getting between 35-38mpg (alot of hills here and there). even in my little town, stop and go im getting mid 20's. hmmmm

Funny though, my 530i and the 320 get about the same city mileage, highway is where it makes the difference.
