I average 19l/100KM. Most of it downtown toronto. With this car I am surprised how much driving style affects gas consumption. I have had 15l/100km on the same route with slower acceleration.

I haven't exactly pounded it in the city, but maybe I will try to granny it and see how much it changes.

You don't need to granny it, in fact you want to get out of first and second gears as quickly as possible and with a fairly wide open throttle (low throttle loss). After that it's more a function of smoothness and avoiding high revs/low load which is the black hole where most M3 drivers are throwing away gas. I'm now down to 11.1 l./100 km. average and I am not a slow driver - I generally drive 20 kph over everywhere and 30 or more over on the QEW and 401. After break in I expect to be in the high 10s.

I think there was a "JOKE" in there somewhere......

Here is my average:

I hope it was a JOKE when he said it's downhill both ways

I agree you don't need to granny it, but stop and go traffic, numerous traffic lights and trying to pass the TTC street cars ;-), will have a significant impact to fuel consumption. I have also found that using shell gas has improved fuel consumption.

Maybe the stroker should include a larger tank or a fuel cell in the trunk

Now I remember why I left Toronto!

What RPM should I shift at, should I shift low enough that I'm lugging third, or go to 3000 then shift?

Fortunately I have a Route that only has a bit of streetcar traffic, Stop signs are probably what kills me.

Pressing the M button too many time also kills my fuel consumption. But it is so much fun.

I can't be sure, since I'm still breaking it in and it's a DCT. I'm mostly driving it in D4 and shifting to S3 in traffic jams. With my E46 I shifted from 1st and 2nd at 3000 and kept the loudness button off. I averaged 9.8 with the E46, 9.2 with the 335i. The stop signs are tough.

The car is far too much fun to drive to worry about granny footing it to save a couple of bucks in gas... you might as well save real money and buy a 328.


If you drive 12,000 miles a year and get 15mpg, you are buying 800 gallons of gas a year. At 20mpg you are buying 600 gallons.

At 2.75/gallon, the additional 200 gallons will cost you just $550 per year, or about an additional 10 bucks a week.

Whether you lease you car or bought it, you are paying about 400 bucks a month extra to drive your M3 over the cost of a 328 (assuming a 3 year ownership).

Why pay all that extra $$ to drive an M car and then go limping around to save 10 bucks a week in gas? Pointless.

If you have to worry about an extra 500 bucks a year in gas, you have no business owning an M car.

Put me in the drive it like you stole it column.

GO YANKEES!!! They are crying in those towels in Philly.

Well, we need to do this in metric in Canada. I drive 60,000 kilometers a year. An extra 3.7 l./100 km. works out to an additional 2,220 liters, at a price of $1 per liter or more. But it isn't really about the money.
