You never know when you might be in a situation where you are forced to push that limit a little - it is good to know that there is less left when it hits "0" than my 135.

Like the Seinfeld episode where Kramer made the salesman see how far they could go?

Has anybody with a 228i 8speed gotten close to the advertised 36mpg highway mileage yet?

I nver understood why they got such terrible mileage, its just a 2-liter, why does it do so terribly on the highway where you're not using the turbo? My SRT4 was a 2.4-liter making over 450hp and I still got 30mpg highway.

Simple, drivetrain losses. Any full-time AWD vehicle will see comparatively less MPG than a similar RWD or FWD vehicle. Its science.

Agreed AWD is going to be lower, but my new car choice would have just been a lot harder of a decision for me if they could get mpg's as high as the CLA45 or the new Golf-R scheduled for next year.

I haven't had a BMW for many years (Euro 1979 635CSi) and have lately been driving Evo IX with E85 tune and bigger injectors (very reliable 425hp and 435 tq from 2.0L). Is this something that works well with the turbo Bimmers or it it recommended to stay with gas?

[Oyinko]

I do 20-22mpg mostly in eco mode and city.

I like the eco mode because it gives the ride smoother with the gas pedal.

@ 75mpg relatively flat highway mine was displaying anywhere from 37mpg to 50mpg in comfort mode.

displaying on the gauge? if your going off of that, thats not very accurate. you got to see how many miles you guys are getting on a full tank and how many gal. you guys put in

Yeah on the gauge. I dont drive highway normally so no way to get a # there. I havent actually filled up a full tank yet since getting the car but Ill see what it is when I do.

[dalrx]

First run highway today 200 miles round trip in echo pro 70mph avg got 35 mpg.

[PigWig]

I'm about halfway through my second tank, and my MPG is hovering between 19.5-20 MPG (auto, M235, ~350-400 miles).

[DanG]

I got 25 mpg on my first tank. Mainly city driving with start stop on in comfort mode.

[jhbjrpdx]

I got pretty awful 17 mpg on the first tank of gas. I had a Mini S and drove the crap out of it around town. It is hard to adjust.

[eric135i]

owned my '12 Impreza for little over 2 yrs, rated at 36mpg hwy and only gotten 27-29mpg. 80-90% highway @ 70-75mph avg. horrible to say the least, Subie forum members have reported same results.

For those reporting MPG use this calculation to get your exact MPG

Calculating Your Car's Miles Per Gallon (MPG)

1. Fill up your car's gas tank all the way.
2. If your car has a trip odometer, reset it, or record the master odometer mileage.
3. Drive your car as you normally would, and let your gas tank deplete to at least a half of a tank of gas.
4. Get to the gas station and fill your tank again.
5. Record the amount of gas it took to refill the tank.
6. Record the elapsed trip miles or new odometer mileage.

calculation
EX: 312miles ÷ 13gallons = 24mpg

I'm gunna be that Canadian troll who says that on my first half tank I have been getting 9.6 L/100 city. While diving like I just bought a new bmw. Not to bad really. Better than the 2.0T in my old VW.

You just blew my mind haha

My 335i w/AT averages between 25mpg to 28mpg (seasonal) on mixed driving, mostly suburban driving.
And I don't drive like granny at all.
My commute is in traffic that's going between 75mph to 85mph.

That AT makes a good bit of difference in MPG. Two over drive gears is no joke for increasing fuel mileage.
And the F30 is heavier than the 2 series.
How much, I haven't looked it up yet.

I'm surprised by this 20-22 mpg. Are these MT's?
My 135i MT was a bit better than that, around 23mpg consistently.

That's still well below 30mpg. Also, are you using the computer on the car or doing the real calc?

20-22 sounds right for someone driving the car hard, even low if they are having a whale of a time

Has anyone tested the accuracy of the fuel economy that the car's computer reports and the actual fuel economy? In my experience, most cars report about 1L/100km better than reality. However my last car (2014 IS350) was almost dead-on, with only 0.1-0.2 errancy. I'll be testing this when I go for my first fill-up.
