No.
Mixed consumption includes “urban” type consumption where the test cycles include accelerations.

The interest of standardized consumption is precisely that it is, standardized...
So comparable to each other.

you are looking for me! : Cry:

So why do we never reach building values?

Because these tests are done by machines: cheesy:

little parenthesis on GPS accuracy:

some researchers, specialists in continental drift now use it to measure movements of the order of 5 cm / year

You will never have a great precision with a civil GPS military GPS have a system of correction to align with the random errors, made voluntarily to the satellites. to thwart a use that intended evils could use the system
some misiles work with great precision on the order of a meter.
Currently we could make a GPS landing if there was not this random error that the Americans control on their satellite,
To have more precision we combine a (Laurenc C) ancestor of GPS we used it for air navigation until the arrival of GPS originally it is transmitters installed on the Atlantic coast (Caribou name code) for the navigation of boats, in operation since the last war, they are still in operation, but more for a long time, the device sold connects with the GPS and reduces the error much, although the gps certain day it is precise repetitive in 50 meters and other times ...
civil aviation is warned when they make big mistakes or modifications, most pilots in the north rely on GPS

Because these tests are done by machines : Cheesy:
We can approach the "extra-urban" values ​​on the road, with a very calm driving.
The fact that they are not reproduced just indicates that the test cycles do not really correspond to "real" driving ...

This is not very troublesome since the goal is, first of all, to be able to compare different vehicles with each other reliably.

Moreover, it is not "the manufacturers" ... : roll: who do the measurements, but certification bodies.

Maybe but when we have 99% of its figure (well I probably exaggerate a bit it would be necessary to see if the figures of UTAC are accessible ...) which comes from the manufacturer I do not know if we can always qualify them d 'independent.

You keep driving in BX, know that the consumption of the ZX-TD from 1992 is given for 4.3L at 100 to 90km / h? A nice joke, right?

I'm not riding a BX! : Evil:





: Lol: In XM, don't confuse!

For your ZX, if you are having fun making a flat journey on the motorway at 90 km / h, you will probably approach 5 l / 5,5 l per 100 km ...

Under the same conditions, my first XM (atmo) was given for 4,9 l / 100

What do I conclude from this? That my XM will consume more than the ZX, that's all ... 8)



For UTAC or other certification body in the automotive sector, I did not say that they were "independent", I said that they were not manufacturers, it is a little different in the sense that they have no interest in favoring one or the other even if they cannot do without it.

What, it's a BX !!! I had one and I was really happy with it: great handling, excellent braking (4 hydraulic disc brakes) and fairly low fuel consumption for the time (6,5l / 100 measured in extra urban for a 1.9l D atmo of 1991)

It's super ugly, okay. But the fact that it is so ugly makes it possible to buy them secondhand largely under the dimension.
When a moron dumped me in the ditch with, my insurance reimbursed me 13000F (it was not yet € uro) while I bought it 1 year before at 8000F.
In addition, there are parts in all the scrap yards.

I think it's a great value for money for small budgets.

It's still 20% "too much" ... an unacceptable margin of error in many other fields of activity ... but since the manufacturers are the strongest they can afford to give a damn about their customer. .

We understand each other well but the nuance is thin ...
