I don't own a N20 or 26, but having had at least 4 loaners with the N20/N26 I get between 24 and 25 MPG with 50% City/50% Highway driving in sport with a heavy foot (8-speed auto). In comparison, I get about 23-24 MPG driving in the same manner and in the same conditions with my 435i MPPK with a 6-speed MT. The only BMW loaner that I actually got really good gas mileage with was a 328d, where I got 35 MPG combined, driving like a j-hole.

20 mpg with 90% city of SF driving 10% freeway

N 20. 24 MPG mostly around town, average speed 32MPH. Despite being 600 pounds heavier that's 4 MPG better than my '07 Altima.

I'm don't exactly drive the car gingerly and do spend a lot of time in traffic during the week which should be considered with my numbers:

20ish. I drive around town a lot, when I'm on the highway my mileage is nothing short of incredible though.

I just went thru an entire tank driving in Sport Mode on the streets and Eco Pro on the highways. I got 285 miles, 90 of which were highway. 21 total mpg.

[Jay757]

About 23mpg... I can drive pretty sporty at times.

Hi,
I have 2014 F30 with 41K miles on it and use Fuel Buddy on my Samsung phone to track MPG & some other auto related expenses.

Car's average MPG currently is 30.3; get about 34 on highway & 24 around town

[spuntyb]

20k miles. 22.3mpg. NYC.

[johnsonlwu]

Cold start. 5 minute commutes are terrible to mileage even if you simply hop on freeway and exit to destination.

I think that you're using the modes backwards, if you're trying to higher fuel economy. Acceleration is what kills mileage; maintaining speed is pretty efficient (discounting wind resistance at high speeds). Eco Pro works, in part, by moderating throttle response so that you can't "take off" from a stop sign or traffic light.

So, moderating throttle response during highway driving, which is typically more about near-constant speed than it is about stop-and-go driving, does little to help mileage. Worse yet, using Sport for city driving boosts acceleration from stops, dragging mileage down even more than Comfort would.

You'd be better off (but a bit soulless) using Eco in the city (to drive more calmly) and Sport on the highway (for the times when you need to pass).

Lifetime of my 320i is 27.8mpg

I don't know how to get more out of here really... I'm around 75% highway 25% street.

What's more impressive, is when I drive her hard, the MPG barely changes.

[kadify]

N20 average 25.3 mpg atm, have about a 48 mile daily roundtrip with 42 of those being on the highway. Hopefully in the summer it will improve if I use the AC less. TBH I don't drive that crazily and really thought I'd get better gas mileage than I do.

I understand where you're coming from. I'm going to try Comfort Mode on the highways just because I can get 8th gear. It's difficult for me to drive in Eco, or even Comfort, in the city simply because I enjoy having the ability to zip in and out of traffic with ease when in Sport.

What mode do you usually drive in?

I'm always switching between Sport and comfort in City. If on freeway and it's moving, I'll have it in Comfort.....

^^ this.

I like to be able to pull away from lights spiritedly at times.

[pentagon]

19.6 mpg in NYC with average speed of like 12miles/h

[thornfrog]

328i xDrive ~12k mile so far. Avg 28.8 mpg. Comfort mode mostly.

[LMK5]

N26; comfort mode; spirited driving at all times:
25MPG at 28.7MPH average speed over the long term--this includes my 12 mile round trip commute over semi-urban streets and an occasional highway drive.

In my typical short term driving, I'll get around 300 miles and then fill up with 13.5 gallons, resulting in about 22.2MPG.

The N20/26 must have the best performance+efficiency characteristics in the business.

[subrven1]

400 to 430 Miles full tank of gas.

28/29 MPG

Comfort/Sport mode mix

Highway/City mix


Drive about 60 miles a day
