Shocking MPG...

Did you have someone push it half way? I can get 36 or 37 on the highway if I set cruise and go into "Granny" mode.
 
Had my car 3 weeks, done 1400 miles and my average is 36.2, but blimey 42.8 that's some going :)
 
Nope guys. I was pushing it! Had cruise on all the way at around 75+

Since I had cruise retrofitted my mpg has improved a fair bit. it seems the engine prefers cruise rather than my right foot!
 
Must have been downhill all the way and a trailing wind! Joking aside that is very impressive although have you checked how accurate the OBC is by brimming the tank and calculating manually, my daily commute entails about 35 miles of motorway and stop start traffic at either end and I generally average around 33-34mpg. This normally drops significantly when I have a bit of fun at the weekend. :D
 
Trip from Brentwood to Norwich this weekend. On A12 managed 42 at 60. On return, managed 33 whilst driving like I had Jacques Cousteau's diving boots on!
 
~40MPG on a long run within the speed limits is about right for a 3.0i I would say. In mine I used to get mid-high thirties without trying at 'normal' ;) third lane motorway speeds. Good work for getting what you did, very impressed!

When my O2 sensor went on the M I drove down the motorway to the dealership at 55-60 the whole journey. I oOnly managed 35mpg! :D
 
That is good - noticed my MPG is better on motorway now using cruise too but nothing like that!
 
In my 3.0l coupe I cant seem to get the average above 25mpg ; thats not hoofing it either but involves a traffic laden commute ? Is this 'normal'?

Since i picked up my Z, in 3k miles i have averaged 28.9mpg - which includes a daiy 13mile commute with some traffic (but as i leave before 7.30 not much) and a monthly motorway drive from Derby to London; on Vpower fuel.

On my motorway sprints at 70-75 i average 40+mpg.

So if you do a lot of short rush hour driving 25 mpg sounds normal to me.

BMW's pump a lot of fuel into the engine when accelerating, which is why MPG is not very good on short runs and/or stop/start traffic. with the CC you're cruising at a particular speed and not accelerating, which you would still do if you were driving without the CC. Therefore better MPG. You'll end up getting your money back on the amount you spent for it.

P.S. that's over twice the MPG I currently get, which is around 20-ish. :cry:
 
reset my MPG when I picked the car up. Now showing 27.1mpg after a few weeks of mostly just phutting around, not really 'hard' driving, but used the sport button more often than I should :)

Thats still 0.5mpg more than my previous 330Ci was showing.

Yup completely agree Peddy. Around town i am lucky to see 25-27mpg when accelerating back and forth

On a hard run with "sport" on, i have had it down to 18mpg. Stuck dawdling in traffic for a few hours it was down to 9mpg :cry:

It does seem that the cruise pays dividend in the long run. The motor comes into its own on the motorway..

Where did you hear this? Interesting peice of info, but with an NA petrol, i thought this was basically impossible as running the car over-rich looses power... Are you sure youre not talking about a Diesel?
 
I average 22mpg roughly. But I was amazed last week, in 6th gear going through the 50mph zone roadworks on the A1 it read 47mpg!
 
Mine averages 28.6 to 30.6 mpg,on a variety of short to medium/longer journeys
tho it can go down to 18mpg when stuck in traffic or town/hard driving

the best i have had from it was 46-48mpg on way home from south england after i bt it,3yrs ago(more recently max has been 42) :D
 
I always keep track of my MPG across fill-ups, ie: note the litres I put in and the odometer readings (using a piece of software on the iPhone called "Road Trip").

My minimum MPG over a tank has been 17.61mpg, maximum has been 24.34, average is about 19mpg.

My daily drive is a 1.5 mile trip either way though, with spirited weekend drives of about 70 miles or so. I think the highest I've seen on the fuel computer is about 37mpg, lowest I've seen is about 19mpg or roundabouts.

Generally speaking the fuel computer over-estimates against the readings I've taken from measuring the distance between fill-ups.
