Measuring car consumption, EU combined cycle

[plasmanu]

"While the automotive industry is constantly seeking to reduce its CO2 emissions, especially to comply with new European standards, F1 surely has interesting lessons to provide to the largest companies in question.

Indeed, the current V6 hybrids are among the most efficient engines in the world (50% energy efficiency), even if they deploy a power approaching 1000 horsepower.

However, this great technological achievement is very little known to the public ... "

"The increasing electrification of vehicles in no way diminishes the interest of motor racing in testing technologies with the aim of applying them to production cars. New products which will be under our hood tomorrow. The example of Renault is emblematic.

ABS, disc brakes, seat belts, direct petrol injection ... all these elements that seem so essential to today's car come from racing. The next major changes in the sector will probably follow the same path.

more and more advanced technologies (but also more and more fragile and expensive in manufacturing and in troubleshooting) between 2CV and F1, these are two completely different worlds. and we went from vehicles of less than a ton to almost double.

[plasmanu]

I much prefer taking a wall facing 200km / h in F1 than 80km / h in 2CV.

Everything on your car comes from competition.
Monthlery is not for the endurance tests of Citroën at the base. And the 2CV is who.
Why would it change.
They are trying by all means to reduce the size of the tank and gain autonomy. It should speak in terms of efficiency.

You have to know how to live with the times.
My first motorcycle was 120kg 12cv 3l / 100 and I took the worst food bowls with it.
Now 199kg 140cv 5l / 100 I fell once to stop by accompanying him by making a U-turn in abutment on the handlebars while calling in slight cant in the middle of the national Ardèche only one Sunday morning around 10h.
I say bravo technology but zero turning radius

They speak of Dantesque condition over a weekend with 3 engines per year to adapt to the vehicle of Mr everyone reliable over a season.
And you answer "indeed the increasingly sophisticated technologies (but also more and more fragile and expensive in manufacture and repair)".
We must not have the same definition of "Dantesque" and "reliable"

[Janic]

We must not have the same definition of "Dantesque" and "reliable"

very probably! the truly reliable would put the garage owners out of work.
for F1 the materials, fuels and oil are not exactly those of everyone. However, it is true that these exceptional vehicles have interesting repercussions for the low and medium range car ... which must not exceed 130 on the highway, i.e. 3.000 / 3.500rpm, not 8.000 at 11.000 rpm !!!!

Ps: the word Dantesque is hardly adapted to this situation.

[plasmanu]

Oh yes.
Dantesque is who can do the most, can do the least.
A 4x4 capable of going through a sandstorm in the middle of the desert at the bottom without flinching, should be able to drive quietly on small roads for a very long time.
And I don't think that competition oils are very different from our commercial synthesis, especially if we add an additive.
I use meca-run P18, ECO 10000 and C99

[Janic]

Oh yes.
Dantesque is who can do the most, can do the least.

« which has the dark and sublime character of Dante's work
DANTESQUE, adjective. Synonyms for the adjective "dantesque". frightening • terrible • apocalyptic • terrible • formidable • tormented

A 4x4 capable of going through a sandstorm in the middle of the desert at the bottom without flinching, should be able to drive quietly or on small roads for a very long time.

Except that the 4x4 are not vehicles of average French and the consumption of these machines does not consume according to the NEDC.

And I don't think that competition oils are very different from our commercial synthesis, especially if we add an additive.

Neither oil nor fuel are those of the average consumer in France! Even if synthetic oils are also a technological advance.
So these sports in question, even if they allow certain improvements to the vehicles of the Lambda citizen, it is above all a lucrative business. and therefore without anything to do with the title of the subject from which they escape to pollute shamelessly.

It remains true that pushing an engine to its limits (limits) allows you to check its solidity.
Petrol is petrol. Kerosene is between gasoline and diesel and diesel is diesel.
There is an octane number OK, there I don't know for the competition.
Materials are available everywhere, carbon fiber and its hardener it costs nothing, the stuff to be vacuum-packed yes expensive enough to respect the perfect design of the engineer.
Steel, aluminum is available, titanium less.
And I would like to know the consumption / pollution for 1000hp, carried over to the same downsized engine at 100hp, to know who consumes and pollutes the most.
It's all very well to cry wolf pollution when you know nothing about it.

It makes me think of the fanatical ecologists who wander everywhere alone in the car consuming 8l / 100 and who want to ban the plane which consumes 1l / 100 per passenger when it is full. Who it is that pollutes the most. Supporting figures. But go change the mentality of a fanatic, it's a waste of time. Can't count
