I know this can vary but im just after a rough guide. I don't drive my cars that hard and have a good mix of town and motorway driving.

Is 20 mpg about right???

 

it'll do more than that if youre not kicking its head in all the time i expect

 

Agree more than 20mpg. much more!

from memory I think mine used to do 17mpg at a constant 150mph that I used to set the cruise control to whilst driving through France every weekend last year!

 

awesome

 

I got 36 mpg out of mine on the run.............was only doing about 70mph mind you

 

My friend had one after driving a 1.6CVH, it was better on fuel averaging about 33mpg, not bad for an engine with twice the capacity and two more cylinders!

 

I'd expect it to top 30 if you're doing decent runs, averaging at least 25 under normal use. IE/ Not ridiculously short runs each day and/or always caining it, just a nice blend.

 

When i bought mine 4 months ago,the computer showed the previous owner averaged 21.5 mpg. I have averaged 22.7 in the last 4 months with a mix of town and dual carraigeway driving,taking it relatively easy and i rarely floor it...Bmw quote combined at 22 mpg iirc
There is no way you will get some of the figures mentioned here unless you do 99% motorway driving at 70mph,i have taken it really easy on one tank and the best i got is 25mpg, driving like a pensioner.

my pal had one (smg) and he doesn't drive fast and he only did about 20mpg......

 

It will be better on petrol than you think when i sold mine & got a focus st3 06 plate i thought the focus had a hole in the tank compared to my m3

 

i can get 32mpg out of my e36 at a steady 80mph. average since i have had the car is 25mpg,thats over the last 12 months and includes a ring trip and a couple of track days.

 

M3s are pretty good on fuel considering the size and power of them. You should get about 26mpg on average.

 

I almost bought one but got a Vectra 2.6 V6 instead as a cheap but nice runabout, that only does 21 - 22mpg round the doors and a bit of motorway use. If you drive like a total fairy it can do 27.4 average but thats no fun.

 

My E36 was always on about 30, no town driving really.
Most I saw was 34 on the motorway with my mate racing things.
Seemed to be better the faster you went according to computer anyway.
Good power to weight, effortless and 6th gear, will do 30 on a run.

 

I drive mine every day. Mostly motorway miles.

Example of the fuel economy as follows.

Warm up, no more than 2500 rpm till 75 degrees on oil temp, motorway run, fast, around 120-130 whenever possible (lots of it), runs to limiter maybe 3 to 4 times a tank. A little bit of traffic movement due to getting in and out of Edinburgh. It invariably returns 24mpgs

If you cruise at 70 on motorway, u get 30-35mpgs.

Edited to say - to get as low as 20mpg u must be roasting it around towns, or u must be sustaining more than a constant 130mph. |I have seen 18mpg on cruise control as per porkies comments. That is usually around 140+ on cruise
