I think that the figures shown for new vehicles are blatant lies. My car is a new Fabia 1 1.2 (60) and wanted to do some fuel consumption tests. I was was informed by my dealer that you cannot get true MPG figures until at least 10000 mls on the clock. Yet according to the VCA "The cars tested have to be run-in and must have been driven for at least 1,800 miles (3,000 kilometres) before testing" So the published figures no matter how you drive are false.

You will never see the official figures.

Agreed

All manufacturers have to compete against each other.

They will only ever be a guide anyway, even if done in real-world settings. There are so many conditions, including driving style, that affect MPG that the car you have will never have the same MPG as another car of the same type.

Just browse through all the cars on the Spritverbrauch berechnen und Autokosten verwalten site. If all cars are benchmarked in the same way for MPG then they can be directly compared.

If you really want high MPG buy based on what is likely to get you an MPG figure you like, but don't expect to get MFR's figures.

If you want good mileage, get a vw polo bluemotion...

fuel consumption: 3,8 l/100km; CO2 emissions: 99 g/km.

Dave

fuel consumption: 3,8 l/100km

What does that work out in real money?

The MPG figures for my car are the one's carried out at the govrnment lab. So I have sold a vehicle that cannot do the MPG hat I was informed it could do (MISLEADING ADVERTISING) is it not. Pllease sign my petition at

The fuel consumption figures are only a guide.

They are done in strict conditions, all the cars are done exactly the same.

This shows the reletive difference between cars, so that we can see that car A is better than car B.

Now, if we left this to manufacturers to do on their own, who was to say they would strip the car out, use super premium fuel, tune the car etc to get max figures just for the test and look good on paper.

The tests are done on a rolling road, with an exact set of tests and speeds under scientific conditions.

There is none or little rolling resistance, no wind resisitance, no driver differences etc.

Everything is on an even keal for all manufacturers.

You also get manufacturing differences as the machines that make engines/components wear down themselves.

One car could come of the line and easily get 40mpg. One later that week, from the same line may get 35mpg, all down to the manufacturing process.

I used to have a 2.0DTi Zafira. Book figure was arounf 45, I could never get more than 38 from it, even if driving steady.

Xtrail, book was about 42, I could only get about 35 but a m8 in his Xtrail was getting about 44.

Navara I had was a book of 32. I could regularily get 35 if taking it easy.

My vRS book is 36.7 for urban/49.6 for combined cycle. Im getting anywhere between 40 and 50 when driven really hard on back roads to gently wafting along for 8 miles to SWMBO's parents.

So, how would you suggest it was done?

Why? Everyone will get differnt MPG from a car anyway, so any set of figures is only good as a relative comparison between cars. So long as the tests are all carried out to a standard, that's OK.

I suspect that if you used deliberate economy techniques you might get close to the figure, but by god, you'll be bored. And everyone else will overtake you .

i would say the most simple factor in getting less than manufacturer figures is the road surfaces and the actual driver of the car.

these 2 factors alone would make a massive difference. i mean i travel only 5 miles to work some days and i travel on so many different surfaces, at different angles, inclines, declines etc etc! it would be truely impossible to give a true set of figures unless all the roads and drivers in the world were the same as in the test situation!

you say they are misleading, i think the manufacturers would simply say prove it! after all they MUST have had at least one car do the figures in a test to publish them, so therefore they arent lying, or misleading anyone.

end of the day they are a good guide to compare different cars. but personally i drive a 1.9tdi fabia estate. it states on a urban run i should get 44.1mpg. i normally get somewhere between 42 and 45.

You will never see the official figures.

Why not? I've never failed to reach the manufacturer's mpg figures in any car I've tried to do so in. You have to try though, you can't expect to get both the 0-60 and the 50-whatever mpg every time you drive drive You have to choose, mpg or performance, you can't have both!

Look ahead and stop braking all the time - I've found mpg is more about how little you brake than how much you accelerate - brakes waste energy, so look ahead, leave a good gap and voila - decent mpg.

HTH

:+1:

You've put "bare" instead of "bear" in the wording of your petition. Probably worth correcting to improve credibility.

It's not correctable unless you know how?

I think the meaning will still be understood .

good advice there! just checked my mpg and im now on 52.5mpg. and thats still mainly urban roads. probably 2:1 in urbans favour. the combi figure on mine is 57mpg, but iirc thats 2:1 ratio in extra urbans favour?

Doesn't it bug you when people are unable to do something and they blame the car

All cars are tested under the same conditions, so should be used for comparing cars against each other... however because conditions are so variable, you can't expect to achieve those actual figures.
