I have just got a new 206 Puegeot HDI diesel, it has airconditioning and someone told me it uses lots of fuel to use it, is this true,?

yep, have air conditioning on will lower Ur fuel economy, meaning U will burn more fuel, but any extra load on the engine will burn more fuel, from the air con, to the water pump, to the power steering, even the alternator will increase the amount of fuel U use.
if U drive at night Ur fuel economy will be slightly worse than during the day, because U will have U lights on, and the alternator will have to put more power back into the battery
air con is most cost effective than opening the windows tho, as this causes drag, making the the whole of the inside of the car act as a mini parachute.

Ok, let me explain. When you turn the airconditioning on, it engages a magnetic clutch on the compressor that engages a belt drive between the compressor and the engine. Because of the extra load on the engine to drive the compressor for the air conditioning, the engine has to work harder to maintain the same amount of revs. To maintain the same amount of revs under a higher load, the engine must get more energy, by burning more fuel. Its not excessive, about the equivalent of driving with both front windows open. This reduces fuel economy by about 10 percent (at higher speeds) by reducing the aerodynamic efficiency of the car, again, creating a situation where the engine must work harder.

your a/c doesnt actually run off diesel, it runs off the drive from the engine. basically the engine drives the compressor for the a/c and as it is another load the engine uses more fuel, for example you have one person in the car it will use a lot less fuel than a car that is fully loaded.
To that end a/c needs the power from the engine, the engine loses that little bit of power, so then the engine has to try and work a little harder, hence the reason why there is more fuel used.

Keep in mind that the A/C itself DOES NOT USE fuel but the motor of your vehicle (which does use diesel) has to work extra hard (thus more fuel for the Peugeot motor) to operate the A/C.
Thus, when I can and particularly on trips, if I can get by without the a/c (and the windows partially open) I turn off the a/c to get better gas mileage

There is a show on Discovery Channel called Mythbusters. They tackled the myth that it takes more gas to drive with the windows down vs. running the air conditioning. I wish I could remember which one they found to be true. If you visit www.discoverychannel.com and look for the Mythbusters website, I bet it will tell you.
The fact about airconditioning is that it will use slightly more fuel to run, than if you drove your car without ever turning the air on.

You will use less fuel with the air on than with the windows open .
A common mistake . The wind resistance with the windows open will cause a lot of drag there for using more fuel .

not a LOT but is does increase fuel consumption by a very small amount. You won't notice the difference so don't worry.
It's not as if you are some american driving a dodge ram or something. Now THEY should worry.
Enjoy your sensible choice of new car and don't worry.

power released via the motor vehicle from its gas is shared between action,a/c,heating, lights and so on. a clean motor vehicle releases optimal plausible power and distributes it completely. because the motor vehicle wears in service, power released is decreased, action,a/c, and so on take a ways more effective power than before for an same effectiveness, those type of ought to for this reason no longer artwork nicely. established upkeep will ascertain performance and positioned the motor vehicle to longer existence.

It takes power from the engine to run the air conditioning compressor....about 3 horsepower...
It takes fuel to generate these 3 horsepower but not much....
Don't worry about it.....Be cool.....

my bf has the same car and you won't even notice the difference. it is very small. i think it reduces the mpg by about 1 mile.
BTW, it is not more economical to open the windows, esp at high speeds as the aerodynamics are affected a great deal.
