Well, according to the computer, i drove 470 miles on the last tank of diesel (1.6tdi 2010), and i put 41 litres in, so by my estimates that means i had 4l left in the tank... so say about 500miles tops, and thats probably about 40-42mpg average...

Exactly... the distance isn't wrong, so therefore the mpg must be wrong, i never got over 45mpg (according to the computer) on any trip..!
I've tracked neatly 8000 miles on 1.2tsi FR which got from new, I know it night be a bit OTT but just really interested in what car can achieve. The car does mainly motorway drives during week and short and a roads during weekends and achieved on average over approx 8000 miles 40mpg. My best being 51.2.
Here's a link to my data for those interested

This thread has been interesting reading for someone that's just bought a 1.4tsi fr. I have a 3 mile each way commute every day so engine not really getting up to temp for long but the computer is reporting anywhere between 25 and 35 this week so far - but I see people are saying it's not to be trusted.
Gaffer - you were looking for experience with other cars - I just traded in a 2010 Clio with the 1.5dci in the 86bhp guise that I'd owned from new. It was probably lifetime averaging 54mpg over 22,000 miles. It was sorely lacking a 6th gear that some other models get as doing a motorway run at a decent speed would take the economy down to low 40s.

Thanks for the info, my ex girl friend from a couple of years ago used to achieve 68-70 mpg at 70 mph from her 2003 Clio Dynamique DCI 80PS. That was the most economical car I've ever driven. Only 5 gears though.
I have pasted below the procedure for measuring the urban driving cycle. However, I can't see my car achieving it's claimed urban figure if I was to follow this procedure.
The european driving cycle seems suspect and it wouldn't surprise me if car manufacturers are cheating.
Urban Test Procedure:
The Urban Driving Cycle, also known as ECE R15 cycle, has been first introduced in 1970 as part of ECE vehicle regulations; the recent version is defined by ECE R83, R84 and R101. The cycle has been designed to represent typical driving conditions of busy European cities, and is characterized by low engine load, low exhaust gas temperature, and a maximum speed of 50 km/h.
When the engine starts, the car pauses for 11 s - if equipped with a manual gearbox, 6 s in neutral (with clutch engaged) and 5 s in the 1st gear (with clutch disengaged) - then slowly accelerates to 15 km/h in 4 s, cruises at constant speed for 8 s, brakes to a full stop in 5 s (manual: last 3 s with clutch disengaged), then stops for 21 s (manual: 16 s in neutral, then 5 s in the 1st gear).
At 49 s, the car slowly accelerates to 32 km/h in 12 s (manual: 5 s in 1st gear, 2 s gear change, then 5 s in the 2nd gear), cruises for 24 s, slowly brakes to a full stop in 11 s (manual: last 3 s with clutch disengaged), then pauses for another 21 s (manual: 16 s in neutral, 5 s in the 1st gear).
At 117 s, the car slowly accelerates to 50 km/h in 26 s (manual: 5 s, 9 s and 8 s in the 1st, 2nd and 3rd gears, with additional 2 × 2 s for gear changes), cruises for 12 s, decelerates to 35 km/h in 8 s, cruises for another 13 s, brakes to a full stop in 12 s (manual: 2 s change to the 2nd gear, 7 s in the 2nd gear, last 3 s with clutch disengaged), then pauses for 7 s (manual: in neutral with clutch engaged).
The cycle ends on 195 s after a theoretical distance of 1017 meters, then it repeats four consecutive times. Total duration is 780 s (13 minutes) over a theoretical distance of 4067 meters, with an average speed of 18.77 km/h.

If you were the computer on the low friction rolling road used to do this test you would have no problem achieving the numbers.
A computer is the only way that the test can possibly be accurately repeated.
There are NO hills in the test, no variations of tyre ( they will use the hardest tyre they can ), and more importantly NO corners ( cornering is less ecanomical than straight line driving )
The test is complete bo**ox and nothing to do with real world driving.
What's more there is no wind and although the first part of the test is done from a cold start, the car is already at a temperature of 20 degrees I believe.
By the way, over the 6000+ miles from new my 1.2 TSI SE has averaged 45.1 mpg. The claimed figure is 55.4.
My previous Honda Civic 1.4 averaged about 43 mpg from new and the claimed figure was 44.1.
Perhaps the makers are getting better at tweaking their cars to suit the Euro test?

Completely agree - In three generations of VAG diesel cars I am finding it harder and harder to get the same fuel consumption.
But the cars are claiming better and better mpg figures.
Why can't car peeps give us 'real' world figures, with a decent test route/ conditions? If What Car? can do it, and Which? why can't they? I always read the road tests, and how they achieved those results. Not too impressed with the MPG from my Ibiza. It's a great car, but the MPG is a worry. Fuel is going up and up, so may have to consider going smaller, or an older diesel( wound up a tad...)
Not that simple I'm afraid.
Will the test route match your driving conditions or mine?
How will you ensure there is no wind for all tests by all makers?
How will you ensure that the same temperature and humidity is present for all tests run by all makers?
Will you have just one test route for all of Europe? If so there will be a queue to use it. If not it will be hard to ensure that all such routes are identical - same road surface same layout, same hills same bends etc.
There can be no traffic since traffic is not repeatable. So it can't be representative of real world driving can it?
etc. etc. etc.

They do simulate wind resistance with the rolling road resistance, but I've never thought about corners. Changing direction uses a fair amount of energy so that should be included. Doesn't explain why some cars are better at getting close to the test figures than others. The C3 air dream is very economical in real world driving.
Yes but not the wind itself. Driving into a 30 mph head wind for example will result in air resistance the same as driving 30 mph faster.
But some cars will produce more energy sapping tyre scrub as they corner than will others., so how will you account for that?
Some cars have all electric power steering which may be more efficient than electro-hydraulic. No power steering will be better still.

I get about 35-40mpg, on a 1.6 petrol..... I got that 17 inch alloy however road noise is bad...
