10.6/l per 100 km!

[BimmerBoomer]

That's a solid 22.2 mpg. My use is 40% major highway, 40% secondary highway, 20% urban. By comparison, my E46 M3 averaged 9.8 l/100 km. and my 335i (Dinan tune) 9.2 over the same roads.

[Green///Hell]

Way to go you! Wish I could consume the same, I can't get my tach to read above 18mpg

[graider]

are you shifting at 1k rpm? hehe

[SlammedR8]

Thats great,
Mine is way worse. So how many km do you get per tank?

Btw, DCT guys - in 7th gear, at 120km/h. what does the car rev at?

on my commute I shift to 2nd at 2,000 and 3rd and 4th at 3,000 (2,000 in traffic jams). Mostly I'm in D4 and smooth on the gas. I try to keep the speed under 150 kph.

A calculated 594 km. based on 63 liter tank.

WOW!!!!

Im getting about half that. I used to get about 300-320km per tank. (I reset trip meter every fill up).

I filled up earlier this week, and I promised myself I won't pass 4000 rpm to see how much better mileage I get. Im at around 300km now, with about 90 km on the range.

By the way, its mostly city with a little bit of highway. maybe 20% highway.

[frenchM3dreamer]

in my car i've noticed a HUGE difference, even on highway trips depending on how i drive...
if i stick to 120 kph in 6th, no downshift to pass (not that i need to, but it sounds damn better), i get up to 750 km per tank (V6, 3.8L, 60 L tank)...
same trip, 140-160 kph, downshift to 4th to pass every slow car (just for fun) and i barely go over 420 kms on that same tank
so yeah sometimes it makes you think: is the poor mileage worth the fun ON EVERY TRIP?...
mhm, let me think... YES IT IS
i didnt even think the M3 could get over 20 mpg, that good to know i guess

Had me wondering, but the 22.2MPG is for US gals, it would be 26.65 in Imperial gals.

All of which is pretty good, I do not get that kind of mileage, but I know it is far more efficient on the hiway. The stop/start of urban driving is a mileage-killer. Of course, it takes strong discipline to resist driving the car aggresively, wait a minute, that's why I bought it......

[Dieselino]

Im getting a good consistant 15 MPG, this car drinks gas.

[Doru in Romania]

i got 13.5 average on open road and 18-22 in the city. you can get 10l/1ookm at 100/h with cruise control. that's not real world m driving.

don't get the idea that I don't drive fairly fast tuco. But the E46 was much the same: use the loudness button, the throttle and the brakes with abandon and the gas goes straight out the pipes.

[jbeene]

I'm astonished by how bad the city gas mileage can get but then I didn't buy the car for any reason other than the fact that it is exceptionally efficient at gathering and maintaining speed no matter how curvy the road gets

In the winter, over my 15 km commute, I have routinely seen 20 litres per 100km and often get less than 300km out of a tank.

On the highway I think the best I've seen is 11.0 per 100.

Usually after a year of driving a car I find some excuse to get a new one, not the case at all with this car. Absolutely love it.

[Vise]

My last two tanks I've been averaging around 15.0L/100kms. Mostly highway driving (DVP for people in the Toronto area) too.

Wish I was getting anything close to 10.6L/100km, I think my best tank ever was about 12.5 per 100.

You and me both my friend!
But like you said, worth every penny!!

[r53s65e90]

This is the best I ever saw on 101 northbound from San Jose to Redwood City under nearly ideal conditions:
1) Super granny driving
2) Ideal morning traffic density good for 50 mph average
3) 99.9% highway driving

Otherwise average is 15-16mpg

[JCtx]

Yeah, I could get 22 mpg on the highway on my M3, but RVs would be passing me . I get 19+ on the city, which is pretty good (driving mildly, of course), but with the engine screaming at 4K at a paltry 90+, no way in hell I can even break into the 20s. I get better mileage in the city than the highway .

hhahaha! very good point, it can be worse on the highway if your going above 70mph (130 km/h)++

What does the DCT rev at in 7th gear at 60mph (100 km/h) ??? Can anyone verify?

[E90M3CDFR]

Best I've seen has been around 11-12l/100km driving at a semi-constant 130km/h from Paris to the south of France at night. Worst is when I am in Germany on some of the longer unrestricted stretches of autobahn when I see the high side of 20l+/100km.

I expected the fuel consumption to be high so not a big deal. What I would have liked was having a bigger fuel tank, say 80 liters?. That would make the longer trips much faster.

[Atny286]

We have those annoying speed cameras that tracking you over an interval of several miles... so I am bravely driving at 65mph. Then I get in 6th approx 23mpg. On the Autobahn about 8mpg and on average I get 16mph. what did BMW NA tell us? 14-20mph (city-highway) or so?

24.6 mph per 1000 rpm. 2439 @ 60 mph vs. 2600 with the 6 speed. So the DCT has a 6.6% gear advantage on the highway.

My car turns exactly 2,500 rpm at 60, but in a 'real life' comparison, my 6MT turns 72 mph at 3K, compared to 76 mph on a DCT (7th), both with 19s (don't know where's the speed sensor on the M3, by the way) which equates to a 5.5% difference. Pretty close to your mathematical number, even though it seems to be off in my car at 60 mph (tolerances).

There's absolutely no reason why our cars were not geared to turn 80 mph at 3K rpm in top gear, which I consider the absolute minimum speed at 3K for semi-decent highway mileage. And to be specific, my beef is with RANGE, so either higher gearing or a larger tank would have been fine with me. Good day.
