Been pretty happy with the economy of my 325D Touring.. 3 litre straight six with a remap (~250bhp) returns ~43mpg (tank to tank) in mixed driving - not too far off the 47mpg official figure. Seems to respond well to the occasional thrashing too..

Poor fuel economy from a diesel - does this sound right to you?

I find some of your mpg claims basically incredible. How slowly do you drive? Are these real figures?
Hire car this weekend - 250 mile trip across two cities, 40 miles of A road rest motorway. 28 mpg

My 2003 Passat TDI used to regularly exceed it's quoted book figure, with one memorable occasion averaging 67mpg on a long, slow drive from Manchester to Devon. The BMW, however, quotes up to 70mpg and averages, even being driven carefully on the motorway, 42.

My thoughts exactly. The only place I have ever got close to the supposed MPG figures of any of my cars has been in France on very quiet roads.

I drive at the speed limit almost all the time, and usually avoiding heavy traffic. You can easily gain 10% fuel economy by paying attention to fuel economy techniques, I reckon.
Oh and on the motorway I use cruise control.

I drive six inches from the bumper of the car in front to maximise the slipstream effect and don't bother with unnecessary power drains like indicators etc..
Seriously though.. real-world figures. I don't drive particularly slowly ('keep up with traffic') but I do try and drive as smoothly as possible and anticipate the road ahead - leaving plenty of space on the motorway to minimise the amount of braking/accelerating needed etc. That and the right tyre pressures (a bit over if anything) and no unnecessary crap in the boot.

What engine was it? I think they do a 1.6 Petrol in the Zafira and it wouldn't surprise me if that managed fairly poor mpg figures lugging a heavy MPV about with a large frontal area. The cold weather won't help either.
With the amount of miles I do, I keep a close eye on the mpg figures my car is achieving. It always takes a dive in the cold weather, but I am currently getting about 57mpg give or take. That's calculated from fill-ups. I drive on the A1 mainly on the way to work, and there are two roundabouts where I probably sit for a total of 20mins/day at least. At the moment I stick to 60mph. From last year, I know that during cold weather if I drive at 70mph, then the fuel consumption is probably nearer 52mpg.
In the summer just gone, driving frugally I regularly used to get over 60mpg over a tank, with a high of 63mpg, I think. The computer shows nearer 67mpg though, but I ignore that.
The car is a 1.9TDi Ibiza, with 130bhp & 6 speed gearbox. 70mph sees it revving at about 1750rpm, so on long motorway cruising it's not really trying at all. Still plenty of grunt for overtakes though, just knock it down to fourth and off it goes.....

thanks for all your advice guys, its helped me to realise that I shouldnt have expected quite so much from my car - and that I have been a little naive with regards to potential figures.
I love the way the Megane drives (honestly) so will put up with 40mpg until I can no longer afford to do so!I've also started to nitice a slight increase in efficiency since the sub zero temps started to fade.

I've got a 1.9 TD Signum, 04 plate and I get on average 46mpg per fill up with keen driving and a little less if heavy footed (reset the average every fill up). Thats a mixture of country lanes, town and duel carridgeway.
Like you said though, as soon as the weather drops my MPG goes really low, annoys me when I have been super keen all the time and it goes down driving exactly the same as before.
My driving style has really changed since caring about MPG and it's surprising how many cars I catch up with over the total journey after they overtake or speed off on the fast bits.

I have a 1.5dci megane estate and currently gettign between 51 and 57 mpg driving it normally. I expect this to go up when the weather impoves and we go back to summer diesel as this seems to make a big difference. For a change the on board comp is indicatting lower than the actual (brim to brim).

I'm not saying anything that could be used in a court of law
The biggest saver on the motorway is to use cruise control.

reading this thread is making me regret ordering a 170bhp passat estate... if it does 40 MPG ish then I should have just gone for the Golf GTI, or the 210bhp petrol passat. fuel economy would have been comparable..I got 35 MPG out of teh test golf I borrowed and ragged the tail off of that! I get 32 MPG in my civic type r driving normally and diesel is more expensive!!! Grrrrr.

I get more MPG up teh motorway driving my car myslef than letting the computer do it!

I agree. Cruise holds at steady speed. When I drive, I hold at steady throttle position or lift off a bit.

Trying not to willy wave too much (mainly as it's impossible to willy wave when you drive a polo) but most of those figures quoted above look a bit rubbish to me.
Admittedly most of my miles are accumulated on my commute which is virtually all dual carriageway. but my 2000 Polo 1.4tdi does an annual average of 65mpg with a high of nearly 71mpg in August last year (although its down to ~63mpg in this cold.) All tracked on fuelly.com with as accurate brim to brim fills as I can (even down to almost exclusevely using the same petrol station - not because I'm anal, I'm just lazy and its the closest one to my house).
Now I've learned to drive a bit more economically I fully expect the average to go up a bit this year.
Now, where did I put my pipe and slippers...Posted 3 months ago # -
BMW 520D M Sport 2008 model and I have got 63mpg on some long trips just cruising along at 55 to 60 mph (all dual carriageway or motorway) Average overall is 55mpg, very impressive for a car of that type, even a years road tax is only £115. Cheap motoring indeed.

If you can get 40mpg (or anything close to it) from a 210bhp petrol Passat, I'll eat your hat as well as my own.
