Just wrapped up my first trip (320 miles each way) in the F30.

Going to my destination I averaged 33.5 MPG, driving mostly in eco mode at speeds of 80-105 MPH.

Coming home I averaged 28.5 MPG, but I was driving aggressive (90-115 MPH) in sport due to many stalls along the way delaying my progress.

One thing I noticed is that the MPG really suffers in sport mode at higher speeds. On a separate trip, I averaged 90 MPH (according to the computer) over a 60 mile trip and returned a measly 21.5 MPG.

Oh yeah, 4 cyl or not, this car is quick.

i think my speed is broken. on the highway i'm always doing 70+ but the screen says like 46.2 and i don't know why. i reset it every time too.

That's average speed that includes any time the engine is on. Anytime you're sitting still has a huge effect on average speed.

I get 40+ mpg hwy @ 70 mph. 8AT, n20.

BMWinGE · 04-06-2012, 02:59 AM

i didn't get anywhere close to that on my trip. Even when I tried to be gentle. of course im typically driving faster. thats awesome.

Robin_NL · 04-06-2012, 04:16 AM

Dutch carmag autoweek.nl tested a 328i Luxury 8AT.
They were not impressed by the 4 cylinder engine sound and by the MPG numbers BMW stated.
They got real world US MPG : 25.5....(9.2 litres/100km).
But they found the engine just fast(which means less MPG logically) and the dynamics very good, as always. 4.5 stars out of 5.

But tbh that MPG is what I get with my 335i 6MT as well.

Robin_NL · 04-07-2012, 06:13 AM

So tomorrow, I'll be taking my F30 for the first big trip to Belgium and monday coming back , a total of about 450 miles.

90% is highway driving. So 30MPG US should be possible with cc speed of about 80mph.

Those are some pretty impressive numbers. A couple of things though- your speed was actually 65 mph, not 70 (based on your distance of 60 miles in 55 minutes). Also, have you verified the accuracy of your trip computer? Most often, the computer will overestimate your mpg, and rarely some cars will underestimate the mpg.

mhdelarosa · 04-13-2012, 07:40 PM

Just finished a trip in my f30 328i automatic using 100% highway from long beach to San Diego.

Avg speed: 70mph
Duration: 1:40 hr
Distance: 114 miles
Consumption: 38.8 mpg

Did it mostly in Eco mode, but downshifted several times here and there to vary my RPMs for break in.

Prior to that long trip, my avg speed was 25mph with fuel economy of about 31mpg. Prob 50% highway and 50%city.

Grumpy514 · 04-13-2012, 09:45 PM

I love what I am seeing here for gas mileage! I also absolutely love the resolution in the screens on these cars. So crisp!

malc410326 · 04-13-2012, 10:56 PM

Now up to 29.1mpg, mostly city driving....Completely satisfied so far!

justinnum1 · 04-13-2012, 11:32 PM

im avg 24.1mpg 1200 miles, 70% city 30% highway mostly comfort mode
