Thinking of saving petrol, well it would be foolhardy thinking you would save a lot of money because you won't, as you would need lot of road, coasting is something I have done safely in all my cars throughout their long history, but it is not safe. I mean you have little control of the car, and the cops won't like it if you bump into someone whilst freewheeling.

Not the petrol side of it just does it damage your car as i carnt see how it can but it might some how ?

Haver heard that the car uses more petrol maintaining an idle than just lifting off the accelerator?

10th December 2010, 14:51

Shouldn't damage your car as you are practically idling except momentum/gravity is moving you.

10th December 2010, 15:00

You use more petrol coasting than if you were to lift off the accelerator completely and roll in gear.

Keeping the car running with the clutch down uses petrol, if you are approaching a junction however and drop down into second the engine will rev high but you wont be using any petrol in an injection car. Good old inertia!

And no, it isn't bad for your car. But you'll get through brake pads quicker!

You have done it safely but it is not safe?? How do you work that out? Are you female?

WHy should it not be safe? You still have your brakes and steering, what the difference?

10th December 2010, 15:34

The only thing i can think of is that when you're in gear you can use engine braking along with friction brakes to slow down. Wouldn't say it's a major safety factor though.

Ha ha +1 to the femaleness

I put it in neutral all the time, infact i turn the key off 1 notch while rolling down hills (times are hard). Shitroen obviously thought of this and made the wiring for the alternator to charge while doing your gravity run.

Dunno if it does it any harm running off fresh air - probably does.

My Vecta's fuel computer always preferred me keeping it in gear - changed to 999.9 mpg while rolling in gear and ~80 mpg while coasting.

Cant see it been 'bad' for your car, and to be honest I don't see it as not safe either.

you realise that starting a car uses a lot more petrol than if you were to just leave it in gear and roll?

I doubt it if you just turn the key back on so it bumps itself back to life..

10th December 2010, 16:25

true, bump starting doesn't. Thought you meant you'd turn the car off until you reached the lights then restarted it to move off lol

10th December 2010, 16:28

Nah

ive got a 2 mile hill on my usual way home in the dead of night so I normally try claw back some petrol wasted getting up the other side

The main reason to roll in gear is engine braking, If ur rolling in 2nd gear down a hill you'll not go any faster than 2nd will let you, plus engine breaking use's less petrol and saves ur brake pads alot of wear !

10th December 2010, 17:10

But you roll twice as far without a numb engine and a computer slowing you down.. When i wanna roll i wanna roll i dont want any braking

Lmfbo, I can see it doing any real harm,

10th December 2010, 20:32

Cant See it doin harm !

Not with fuel injection, it used to with carb models because of the accelerator jet.

Nah, cant see that. Give a link to the offence. If it is then its difficult to notice from outside the car

11th December 2010, 18:23

I love coasting

You know to what you infer,actually mate I'm not female but I will tell you what though I'm on their side all the way with sexually bigoted people like you...and another thread disintegrates ,because unfortunately, some people like yourself do not grow up they just grow old.. et tu brute.

12th December 2010, 00:20

Eh? What does all that waffle mean?

No waffle mate only the truth..Your opinion about woman drivers is indeed plain to see, if your going to make inferences about the fairer sex make them constructive and there for other females to see. Sometimes it is prudent when there is [you have] nothing constructive to say, to say nothing at all.

Now to coasting and your other untoward comment, because I coasted [freewheeled] in the late 1960s 1970s, 80,90, 2000, up until the present day does not say it is safe for others to do, it says I am, and obviously many others are prepared to risk take, but then again there are drivers and drivers.aren't there! Your comments mate systematically destroyed this thread, they are bigoted and you really do not think before you write, to use your vernacular ..end of!!

14th December 2010, 21:29

I was told to never coast as you have very little control over the vehicle and it uses more fuel as when you engage the clutch again the engine revs harder also it puts more strain on the clutch and gearbox. Never have done it and will, it just dont make sense as you have gears so use them. Its better for the engine to keep at the same revs than keep going up and down.

14th December 2010, 23:30

what is coasting? im a little thick here

14th December 2010, 23:49

"The act of making progress without much effort"

17th December 2010, 02:25

this is so stupid. how can coasting be dangerous lol? far more dangerous things than not being in gear. And how can it possibly use more fuel?? all your doin is idling. I know theres a fuel cut off when going along in gear without touching the accelerator pedal but the transmission drag is so much that you have to accelerate much sooner than if you just coased in the first place because moving along in gear slows you down so much.

17th December 2010, 04:28

Topgear proved that coasting uses more petrol than staying in gear and driving like your very normal safe driving human being.

ooo intersting will have to have a look at that. Was that on a flat or a hill? I would imaging on a flat yes you would use more fuel but down hill your gaining speed and momentum so you can go further without accellerating. which you wouldn't if in gear.

Think u need to go on youtube and type " women drivers " lol

Meanwhile back at the ranch...............
saxos do use fuel while in gear on the over run, its not like the way top gear described it as saxos are set up differently, but it is a step up from coasting lol

coasting is not dangerous, only difference it makes is the car will run away going downhill, but to those poor drivers out there, just cover the brake if u think the cars going to run away lol

On principle, I wouldn't believe anything Jeremy Clarkson says... if he doesn't like or agree with something, its just 'shit' or 'wrong'... and of course he is always right on Top Gear

The more the manufacturers pay BBC the better the car reviews, its all a con.

^^ This however does make sense. Although I still believe you use less fuel coasting if you do it a lot, its probably not very nice on your car.

.... And the Stig is Jeremy Clarkson.. that's why they try make 'him' out to be the greatest driver in the world... just so you know
