How's your fuel economy?

A267839885568 · 08-26-2014, 07:51 PM

1300 miles, 23.4 MPG

jbraslins · 08-26-2014, 07:53 PM

I always run sport plus, s2. Been wringing its neck pretty good since 1200 mile service.

Daily commutes with some spirited accel, i am getting 16.9 mpg.

Took two decent length trips to the beach (~300 miles each round trip) on interstate crusing tad over 80mph. Reset mpg each time. Averaged 26.2 mpg.

TurboSid · 08-26-2014, 08:15 PM

good point to say what we run our cars on. 99% of the time my car is in all S+ and tranny lvl3 manually shifting. 20-22mpg

Miko M3 · 08-26-2014, 08:17 PM

I am averaging 20 mpg. Took a family of 4 to Wisconsin Dells. 2 hour trip (most highway) full trunk and had 30.7 mpg

4MULA_1 · 08-26-2014, 08:27 PM

Does anyone calculate their MPG by filling up a full tank, and than zeroing the mileage counter, and filling up again and dividing the miles driven since last fill up/gallons filled the second time? I think that is a more accurate way of measuring real MPG vs trusting what the computer tells you.

Still on my first tank..... onboard computer says 4.4 kms/l which translates to 16.6kms per galon under mostly traffic jams, and just a few short spirited runs on a highway, my car has only 170kms (106 miles) on the odometer so far

Dasm3nd · 08-26-2014, 09:08 PM

On board CPU-->23-26 on highway set at sport/comfort/comfort.

AYF80 · 08-26-2014, 09:11 PM

18-22 mixed. 29-32 on cruse control

SteveSpy · 08-26-2014, 09:27 PM

1500 miles in, I drive in efficient mode most of the time. I'm averaging 20.3 mpg right now.

M3ryder55 · 08-26-2014, 09:33 PM

13.8 initially

15-16 for a little

got around 18.8

back down to 16.8

425 miles on the clock. haven't even really gotten on it but my foot is a bit heavy. i averaged 12-13 on my E90.

Jmiller007 · 08-26-2014, 10:29 PM

I am running at 21-22'overall. I took a trip(pre-break in) which was 320 miles each way. I averaged 90, and still got 24 mpg.

Brady1984 · 08-26-2014, 10:41 PM

It's obvious that the car gets decent but not great mileage. Better than can be said about the E9x which was terrible. If it got great mileage it would be one of the most popular things posted. Yeah 20 to 25 is good for a performance car. Corvettes are known for their great highway mileage (7th gear anyone?) the F8x has a small tank (not unreasonably small) and decent mileage (good mileage) for its performance level and is a much better partner for long trips than the previous iteration. Is it a long distance GT car? Hell no.

Wah · 08-26-2014, 10:42 PM

I'm at around 20.5 mpg, still in break in. Tomorrow I take it in for break in service and after that, we'll see.

aperng · 08-26-2014, 11:29 PM

17.9 mpg, 860 miles total on car. Not great, but better than e92 mileage.

Mud · 08-27-2014, 05:22 AM

Picked mine up yesterday (approved used with big discount) and drove 200 miles home, mostly motorway.

Got 40.1mpg on the motorway with traffic and a few speed restriction zones and that dropped to 36.3 when i got into town and played around a bit.

Staggered

CanAutM3 · 08-27-2014, 05:39 AM

I am happily impressed so far. During our ED I was able to do several 650km stints on a single tank. This translates to about 8.6 l/100km or 26 us mpg. This is with the cruise set between 120 and 140km/h (depending on the highway stretch) and a few spirited passes

.

NavyBeeker · 08-27-2014, 07:57 AM

Any new F8x owners on this thread who previously drove an E60 550i? Wonder what the MPG delta is like -- My '08 550i is my current DD but "planning" to go to M3 next year.

Thinking there will definitely be a little improvement, probably not as drastic were I coming from an E9X M3. I can get 25-26MPG on the hwy cruising with the 550i, but typically see more like 19-20 overall with a little fun in "sport" mode now and then.

01ON19 · 08-27-2014, 08:05 AM

Have filled up 6 times. Cumulative mpg is 22.7 ranging from 19-26. Calculated using odometer versus computer.

Onetime237 · 08-27-2014, 08:18 AM

Did about a 500 mile highway drive... not killing it, but averaging 82 mph...27.2mpg.

Clark_Kent · 08-27-2014, 10:44 AM

Are the figures with Start/Stop enabled?

-JLT- · 08-27-2014, 11:21 AM

the lower the mpg, the higher the rate of fun

JeffM-Houston · 08-27-2014, 11:41 AM

We've only had the car two weeks, but we made 2 short day trips out on country two lane roads as well as my daily work driving. I've made sure to fill up and measure mileage for each of the road trips and I have the start/stop disabled.

Daily driving - 19.4 mpg, suburban, 12 miles each way to work, lots of traffic lights with an average speed of probably 24-25 MPH, speed limit is 45.

Road trips - 26.3 mpg, primarily two lane roads driving 55-75.
