On the little POS that I'm currently driving I've measured 7.5 l/100kms, mostly during daily rush-hour traffic. I can't be bothered to do the conversion to MPG :mark: I figure that's about 35mpg.
My 100L tank takes a little over 100 litres and does up to 400 miles if I drive like a granny and don't tow too much.
If I'm towing (which I do about half the time) and it's windy, town driving or large loads, it's far worse.
In short - I dare not work it out :s
I get 12km/l I dont know how mpg that is but I dont think its much
I'm going for a record. My exhaust has fallen off so i'm getting a 100mile plus lift on a flatbed truck which should make for some great mpg figures. **** you car!
At Rally GB last year we got recovered from Cardiff to Fife, I wasn't happy, would rather have driven it :(Quote:

I just accept I have rubbish fuel economy and just get on with it. :)
A friend of mine recently said to me he got 1000 miles out of his tank and was quite proud of himself. I then asked him how much his tank of fuel cost him and he said £90. Doh, what a moron, thats not good fuel economy, infact it was almost as worse an mpg that I get. He then asked me how much my fuel tank cost and how far I could go but he didn't seem to get it. :s
Doing a lot of motorway driving you can really tell that in the last 6 or so months on average people have really slowed down on the motorways.
Its quite surprising how much you can get out of a gallon if you really try, and it doesn't necessarily involve driving like a granny either.
I run a 2.5 Boxster, and when I bought it, I looked at the official euro fuel consumption figures as that was one of the considerations when buying that car over something like an Audi TT. It's pretty easy to beat the 'official' numbers, so I looked into how the official numbers are arrived at.
It turns out, that there is a standardised procedure for doing an MPG test on each car, and all tests are done on a rolling road, by 'drivers' who are representatives of the manufacturer, and so they have a vested interest in trying to get the best numbers possible. So, you would have thought that the MPG figs produced by the manufacturer would be pretty hard to beat?
Not so!
After having had a think about it, a rolling road really isn't the best way to determine these things, as it can't take account of two major factors.
1, The weight of the vehicle
2, The drag (0r more simply how aerodynamic the vehicle is)
So, a car which is heavy, and with brick like aerodynamics will do comparitively well in the test, but give rubbish figs in the real world, and a car which is fairly light, and aerodynamic will do poorly on the test, but will give better figures on the road.
Now, I couldn't find much out about this rolling road test, but surely it can't be that simple, can it? The way I see it, the testing procedure must be flawed. Does anyone know anything about how the official mpg figs are arrived at?
It wouldn't normally matter much, but these days the car tax is calculated according to the CO2/km (a stupider measure would be hard to think of, what is wrong with plain old MPG which anyone can work out?) so there are financial consequences for car owners if the testing isn't properly accurate, especially if it means paying hundreds of pounds a year more or less.
Anyway, I never get less than 30mpg out of my Porsche, and on one motorway run, at a more or less steady 70-75mpg managed 36mpg. If I were to buy a post 51 reg model, then the road tax would go up from £210/yr, to £380-£400/yr, this would plainly not be fair, as I get better mpg than many, but would be taxed more highly!
Anyway, no point complaining about tax, 'they' will have your money off you whatever you do... Just don't expect me to be voting labour in the next election.
It's only taken me about seven years to catch you talking bollocks on here mate ;) Although maybe it was a typo! Still - it's amusing nontheless that you bought a 2.5 litre 6 cylinder sportscar and then started chasing economy!Quote:

My last car was a BMW 320d (e46 generation) and day to day driving it returned a genuine 49mpg (measured by me & a GPS unit - not the on board computer which always overread!). If I drove like a Nun on a long motorway journey (i.e. slap cruise control on at 65mph) it would actually return 60mpg!
Replaced this with a BMW 118d (cheaper co car tax due to lower emissions). Now, this is the same engine, detuned from 167hp to 138hp and 'cleaned up' to EU4. In 90,000 miles I have never had a better return than 47.4 mpg from this car. Interestingly it actually has longer gearing which should help economy.
Other cars we run at work have the same issue - I have two diesel Mondeo's on the fleet, neither of which clear 40mpg easily. Yet an old 1.9Tdi Audi clears 55mpg with ease...
I think the emissions equipment (whatever it may be these days) hurts fuel economy in the quest for lower carbon emissions. Yet we're actually burning more fuel, which has to be refined with a larger impact on the environment...
Net conclusion - it's not a green tax at all. It's just a tax.
Kneeslider - Subaru just built a 4 cylinder boxer turbo diesel. What price Porsche to produce a Flat 6 diesel?
Particulate filters absolutely murder fuel economy. My 406 gave 45 mpg over about 500 miles most of which was done with a broken exhaust as well as a lot of time sat still on the m60 and m62 on friday night not moving for a long time as well as an 80 mile thrash (if you can call driving a diesel a thrash) through Snowdonia. Not bad for an old school 1.9 turbo diesel 406. I've chucked some v power diesel in today and am back to nun mode so we'll see what it's really capable of.
I came back from Melbourne and used 35.3L to travel 830km. That's 23.51km/L or 55.301mpg US and 66.418mpg imperial.
