I start to look at this car, it looks nice and not too expensive.

I do not know if my wife will accept.

Daily article on the subject: http://www.terraeco.net/Trucs-et-astuce ... 42544.html

France started 2012 with a record. The liter of petrol was sold there more expensive than ever: 1,59 euros on average for unleaded 98 the first week of January. However, refueling at this price today would be a good deal, swears my brother Robin. A liter of the same unleaded costs no less than € 1,66 at the time of writing. And diesel, the preferred fuel for the French, is also reaching historic prices. But not all is lost for the 8 out of 10 French people who own a car. Eco-driving, not only reducing your CO2 emissions, can also lower your fuel bill. Chick? By car Simone, or rather… Robin!

Prepare Titin

To spend less, have your car pampered regularly by a mechanic. A simple clogged air filter and your consumption climbs by 10%. Also remember to check your tire pressure when cold every two months. Ditto for the oil level. This reduces the risk of accident and consumption. Another preparation: better to study the course before the start than to press the mushroom once behind the wheel. If you are not plugged into the map, there are many smartphone apps that show the best route based on traffic. Robin will finally take care of removing the dumbbells that have been lying around in his trunk for months: each 100 kilos of load increases consumption by 5%, says Ademe, the Environment and Control Agency. 'energy.

Avoid big blunders

“Most drivers drive too long in first and second, when this is where a car consumes the most. »This, according to Christophe Fayt, eco-driving trainer in Seine-et-Marne, is the most common mistake at the wheel. For him, it is better to go frankly on the pedal to quickly shift gears. And drive in fourth rather than third in town at 50 km / h. You must then stabilize your speed, because it is the accelerations that burn the most energy. According to Ademe, a motorist with an "aggressive" driving consumes 40% more. Another point for my head in the air of brother: make sure to close the tank cap after refueling: the fuel evaporates! " Great ! But that doesn't tell me how to react in exceptional cases, ”says Robin. Case-by-case responses.
"Should we cut the engine when Fiston goes to the bakery?" "
Yes ! Cut it as soon as you stop for more than 20 seconds. A restart will consume less than running a stopped engine.
"Should we turn on the air conditioning or open the windows?" "
It all depends on your speed. Air conditioning generally consumes a lot of fuel, about 1 liter every 100 km. But opening windows on the highway reduces the aerodynamics of your vehicle. You can therefore lower them in town and opt for air conditioning on the highway.
"Trailer, gallery or roof box to transport my luggage?" "
"Prefer the trailer," says our eco-trainer. Because roof boxes and galleries increase consumption by 10% to 20%, much more than a trailer, which has no wind resistance. Be careful however, a trailer requires a lot of maintenance. In any case, be sure to take down these accessories once your trip is over.
The "little extra"?
Do you want to go further? Use the engine brake over the brake pedal. And reduce your speed as soon as you can. By driving at 110 km / h instead of 130, you save more than 10 liters of fuel on a 500 km journey! You can also opt for carpooling: you will consume as much, but you can share the costs.

Race report

The Ademe ensures that eco-driving can reduce fuel consumption by at least one to two liters every 100 km. For Robin, who runs 12 a year, unleaded 000, the economy is not slim. At the average price observed since January 98, ie 2012 euros per liter, his annual bill will be reduced by 1,62 euros if he follows these advice. " And me ? “Asks friend David, who runs 291 terminals per year on diesel, which now costs 20 cents less per liter. The annual saving will amount to about 000 euros, answers the calculator. Shall we go to refuel? -

For those who can, try to deactivate the traction / stability assistants, with me it's 10% less consumption because of a breakdown now: https://www.econologie.com/forums/panne-bmw- ... 12728.html

Admittedly it's a bit soft but nothing more and we are still in the flow of normal traffic, including on the national or bypass where I drive around 90km / h.
I obviously share this opinion after more than 100.000km in 106. I would add that most electric AND hybrid cars (the models with a continuously variable transmission) naturally encourage quiet driving synonymous with economy by the fact that engine noise which is no longer directly linked to acceleration.

PS: the nominal power of the 106 electric is 11kW or 15hp and at most 22kW or 30hp for a short time.

If less than 15hp (8hp) is enough to maintain a vehicle of 1100kg at 90kmh on the flat it gives an idea of ​​the waste which consists in mass manufacturing vehicles of 150hp of which only 10% are useful in current use ...

I see what you mean Citro, but more than power, it is the torque that drivers are looking for ...

And in thermal, to have torque ... you need power!

Compare the maximum torque of your 15 hp electric motor ... it must be equivalent to that of a 40 to 50 hp thermal engine ...

No?

Indeed, and this is one of the main advantages of the electric motor, the torque is maximum at start-up and the torque curve is much more linear than on a heat engine ... As there is no change in speed , there is no break in torque, acceleration is continuous ...
In town, with 15hp, you scrape off the thermals each time they disengage because the electric motor does not stop accelerating.

the maximum torque of our 106 / sax elec is 180Nm pedal fully from the first revolutions / min
better than a Honda S200 2.0L for example or a twingo RS 1.6L

Ah yes anyway ... 180 Nm for 15 hp only! : Shock:

Well we don't have the same Citro cars ...
yes for the 0/50 km / h (and still do not have the thermal conductor on the side is a nervous) but for the 50 to 90 the acceleration becomes almost zero ... This morning on portions of national between roundabouts I was well pushed in the ass by a 44 tonnes in charge of 440cv or 10cv per ton ... while I was swinging the econometre in the red for by sequences of 10 seconds max 10 seconds of orange ...

Big differences appear at the slightest problem when you have so little power and use this power at more than 80% ...
Behavior between my wife's car and mine is very different. Her car has always been more lively while it has 4 doors and mine is a commercial, therefore lighter.

Do not confuse torque and acceleration. The more the speed increases, the more the aerodynamic and other losses increase ...
It's the same on a 150hp car that goes up to 200kmh. From 180 km / h, the acceleration becomes almost zero ...
