I doubt that a 750CV vehicle like the adventador will only be 24,7 - 10,7 - 16 L / 100 km except according to the NEDC, but at 350km / h it is an abyss of consumption and subsequent pollution. Same thing for high speed diesel. So these standards are phony and company.


Hey Ho reveil .... According to the NEDCC ... on the 750CV ... only 1/10 are used ...

rather counts in the 100l / 100km ... like for example the bugatti veyron : Mrgreen: the autonomy of the tank at 400km / h corresponds to the wear of the tire train ... 12mn : Mrgreen:

Even much less.
It probably takes 20 to 30hp to pass the NEDC cycle.

The problem is that the more powerful vehicles we offer, the more their owners will tend to use a fraction of this superfluous power and therefore WASTE ...

Displaying higher and higher power characteristics combined with lower consumption and increasing masses is nonsense ...

Decreasing wastage is one thing (through "hybridization"), but this principle quickly reaches its limits ...

Comes a moment or to move a mass at a given speed, it will take a quantity of energy, therefore of minimum fuel which cannot be less than the quantity of energy necessary to provide this work ...

I think that the ecological bonuses should apply to virtuous vehicles in terms of REASONABLE power.

That is to say, vehicles restrained so as not to overconsume.

I find scandalous, irresponsible and untrue the words we often hear from motorists who claim that "comfortable" power increases their "safety". Superfluous power is a push to crime, to excess, to unnecessary pollution ...

On the contrary, a "standardized" power, in connection with the recommendations of THE ROAD CODE, puts everyone on an equal footing so that everyone respects the rules for themselves and for safety and health (pollution, noise and accident-prone behavior. ) of all.

Yes Citro, I understand.

However, I banned the displacements below 1,6l. precisely for safety reasons and also durability.

Indeed, "small" engines break more often. And have problems due to the expansions / retractions of materials that the bigger ones have too, but much less. (Cylinder out-of-round problem, Nissan Micra, assemblies including the pressed valve seats so less resistant, Renault Mégane broken engines, etc.)

And especially on the highway, I feel a lot safer with a reserve of power when you have a sick person a few meters behind you, big lights on flashing to death and completely pissed off to force you to fold back to pass you, while you are already donations within regulatory speed limits! In these cases, as I still have some under my feet, I put full pot and easily pass the other guy on my right and who prevents me from falling back and at the same time I increase the safety distance in case emergency braking! Then it's me who follows the guy who unwittingly becomes "ram car" and who opens the way for me : Mrgreen: (not too fast anyway ...)
Do that with a 1 liter or 1,3 I don't even think about it!

1,6 liter ??? do you need so much

I am afraid that some manufacturer willfully make low-end low quality to push to buy bigger

at the time where the gendarme went to bed like the hens, and where there was no automatic radar I crossed France at 150km / h with GS 1220cm3 then at 180km / h with GSA 1300cm3 ... it held up without weakening up to 300 km ... they are in my garden because of too rusty bodywork but the engines still work

they were able to drive quickly thanks to good aerodynamics and in safety thanks to very good brakes, and they became economical at low speed without any mechanical progress! I saw my consumption decrease exactly like the modern cars of other people around me! to save money just slow down

You are undoubtedly right, it must be possible to make durable engines in smaller displacement! But it depends on the alloy because to consume less, always less and even less, today you need lighter engines, so necessarily more fragile, I imagine ...

By the way, believe me if you want but if you go towards Grenoble, over there they drive like crazy and you can be happy with a 1,6l to get out of the embarrassment ... And that's right still a "reasonable" displacement.

without forgetting that the weight of vehicles has almost doubled for the same use. Panhard PL17 very bulky approx 900kg, a 2cv less than 500kg

Rather than the size of the engines, we could look at the technical solutions adopted and the associated reliability. Out-of-competition vehicles are not borderline for the holding of materials / mechanisms / assemblies etc ..., they are supposed to do like 200000 km. But on "cheap" vehicles, manufacturers seek more to optimize their costs and certain known more reliable and more expensive solutions are not retained.

For example, rocker arm covers or intake manifolds can be made of plastic instead of aluminum. It's lighter, much cheaper for the manufacturer ...... but after x years of use in hot oil and or under an overheated hood, the aluminum has not moved but the plastic can deform, allow oil to escape or allow air to enter which disturbs the carburation. In both cases, we can end up with a breakage "for stupidity".

And especially on the highway, I feel a lot safer with a reserve of power when you have a sick person a few meters behind you, big lights on flashing to death and completely pissed off to force you to fold back to pass you, while you are already donations within regulatory speed limits!

In this case, I let the excited go around without modifying my speed in the least, the road is for everyone and the plum for those who exceed the speed limits. By doubling me further, if he makes me an obscene gesture, I send him a kiss, which does not calm him more often : Mrgreen:

Obviously you send him a kiss with the hand ... but being careful to keep the middle finger upright. : Cheesy:

180kmh on the odometer ...
The fastest of the GS, the GSA X3 topped out at 163kmh ...
At these speeds, the GS was a fuel sinkhole.

Obamot I too have been the subject of similar acts of road violence comparable to those you describe. I refuse to react by changing my way of driving, that would be to prove them right. Foreign heavyweights are also often guilty of such behavior.

I don't think downsizing is a good solution and I share your point of view on the mechanical wear of small engines, unless they equip light vehicles.
A naturally aspirated 2-liter petrol engine running between 1500 and 3000rpm is a relevant choice in that it allows the fuel to be more completely burned if heavy throttles as well as under and high revs are avoided.

My old 260.000 km petrol MPV thus consumed an average of 9.33 lites during my last vacation in the Alps and in Italy on 2200 km of motorway and mountain journeys, fully loaded and air conditioning on the move.
The "co-financing" allows us to travel at a reasonable price by dividing the costs per household, i.e. 4.67l / 100km and 6.30 € / 100km for each family as well as the toll costs divided by 2. 8)
