Hello macro, there is a little joke for the owner of the quote

Not on modern cars! For a long time, the "fan" is no longer driven by a belt connected to the engine and therefore proportional to the engine speed ... It is electric ... It was true with "daddy's" cars, where it was necessary to make the mill. for this reason, indeed ... (well, in summer).

So the cooling is 3/4 of the time (even more) free, that is to say linked only to the speed. And not at the engaged speed (3rd, 4th ...) and at engine speed ...

: Mrgreen:

To return to cooling, on certain prepared 4 x 4 or all-terrain vehicles, they directly wire a command to trigger the electric fan manually. This avoids breakage when the radiator has lost its efficiency, when it is partly covered with earth, mud, leaves, etc. : Mrgreen:

The 4 X 4 covered in mud, we are far from eco-driving ... Let's move on.

Tonight, the last episode of my consumption tests: same flat route, same car, speed stabilized 130 km / h, consumption rose to 8,2 l per 100 km.

So :

90 km / h stabilized: 5,7 to 6 l per 100
110 km / h stabilized: 6,8 to 7,2 l per 100
130 stabilized: 8,2 to 8,3 l per 100 [NB: consumption is more stable, more energy consumed to fight against the air; the "micro-relief plays less]; we also see that these 20 km / h more cost more than the previous ones ...

It's still roughly + 35%!

Your C5 is a real fuel pit ...

That said I am not too surprised my brother (taxi in rural areas) had told me about the maddening consos of the 607 and the C5 of are old box compared to the cars he uses today

Personally I do not come back in mixed routes (highway highway city) a 140cv car of the same size as the C5 which drinks between 5.4 and 6.2 / 100 ... Yet the manufacturer in question is pinned as a big polluter And the franginui it does not do too much in eco driving ...

Effectively.

It is an "old" engine, overhauled. And a 5-speed gearbox that is much too short! (she "mills") ...

It is, I remember, gasoline and not diesel (HDI). And it's the old model, the "ugly one" ...

It was bought secondhand (more than 3 euros cheaper than the same C500 in Diesel and more than 5 euros less expensive than "equivalent models" of more famous brands - Peugeot, VW), at a very low mileage , to be converted into GPL ...

But whatever, this is not the debate. The incidence of speed is, proportionally, roughly the same.

To reassure you, I drive on a daily basis with a C1 GPL. Otherwise, I would look a little ridiculous on this "eco-driving" thread! But she doesn't have a computer to give the instant numbers.

Flat / precision ...

Speed ​​becomes the main force of resistance to the advancement of a vehicle from around ... 90 km / h not before!
We have a subject on speed and consumption with a study to download.

The minimum consumption speeds are currently between 70 and 90km / h (depending on vehicle). We consume more at 30km / h than at 80 ... at steady speed.

Yes, yes, you do well to specify it. I was implicitly in the 90/110/130 km / h.

And I wanted to say that the increase observed with my C5 is reproduced in principle with other vehicles, but of course proportionally to their consumption at 90. So it will not be 1 l more, for example, when we go from 110 to 130 with a car that consumes 4,5 l to 90, but 0,5 l ...

Hi everybody!
Here is my vision of eco-driving that I have been practicing for almost 2 years:

context:
we live in the mountains, I have a drop of 400m to do from the bottom of the valley then our job is 20-25km (highway + town).
Car used: kangoo 2 (diesel dci) and clio 2 (petrol).

We NEVER exceed 90-95km
Considering the short distance, and the traffic, it doesn't change anything in the schedules which can vary by 5 minutes: negligible.

It made us drop the cons. in addition there are lots of advantages:
It makes less noise,
it's cooler,
the risk of a serious accident is reduced, etc ...


You will tell me, yes but to go far, it sucks ...
it's true ... but you have to adapt.
We just made a round trip in the jura (350km one way) max speed: 110kmh.
Similarly, the difference in travel time did not shock us.
You just have to be stuck behind a caravan at the wrong time and your average journey quickly looks like ours;)

It's not all.
If you want to go further in eco driving you have to see further ...

For the moment petrol / diesel costs nothing! what a slab! it's given.
10KWh for 1,5 € frankly it's a gift.
But it may not last so you have to invest to prepare for the big slap. Big slap that will come very gradually to the rhythms of economic crises / recoveries.

What I do :
Each time I fill up, I scrupulously note the amount of the full.
Regularly I transfer from my current account to a specially created account, the same amount as that of the gas tanks.

Goals :
- compared to you, virtually, I already pay double the petrol. My checking account actually lives it.
- Pedagogically, I drive cooler (hence the 90km / h to go to work). I think before going down the mountain (especially to go up) I optimize my routes.
- I save money which brings me (not much), it's aside.
- when the liter is 3 €. I could stop this system. But I'm already paying this price. I'm used to it. I live with. So I adapted my lifestyle.

Are you ready for the 3 € a liter?
(we said, petrol at 10 francs, we would never let that happen ... LOL)
We. we are ready.

But the best part is that the money set aside is used for something.
I ONLY use it for work / expenses with the sole purpose of reducing energy consumption.
- I therefore paid for the insulation of the attic, the garage.
- I'm going to buy a solar water heater.
All his expenses are easy, because the money is no longer on my account. It's a bit offered by our travels.

I hope I haven't been too long ...
Good night.

Hello Dekloo,

On a technical level, your presentation is very consistent for a vehicle thermal.

it's interesting this savings system indexed to the price of the Liter and your personal consumption

However, the work on your house, useful as it may be, will not help you in your travels.

So maybe we will have to think about transport without oil. From walking to the electric car via the 2 wheels ...

I grant you, the offer exists, but remains limited (except that of shoes and pedal bikes :P ).

In fact I am trying to generalize my eco-driving to my lifestyle.
I do not confine myself to the car. So what I spend on "energy saving" work is valid whatever the field.
My 100% carbon tax should allow me to implement solutions to reduce all my consumption, not just petrol. (in addition to petrol, I also reduced my electrical consumption (35% last year, 10% this year), my water consumption)

And in terms of transportation, I tested the bike 2 or 3 days a week. it does it. But I have to get on and off the bike by car (mountain cause).
And I'm asking to buy (on the energy budget) an electric bicycle wheel to adapt it. (to climb the 400m drop)

As for the electric car I do not see where the economy or sustainable development is in this false solution (which in my opinion is only there to reassure the average consumer by making them believe that he will still be able to travel for cheap for the next few decades).

Excellent!

You should apply in 2012: that, across the country, it would change things ...
