What's all this 'coasting in neutral' malarky ?

It's dangerous, period, so why discuss it on here and possibly encourage somebody to try it out and have a potential accident ? FFS ! :wonder:

You're not a fan of engine off coasting then?

The new audi boxes have an option for coasting down hills to improve fuel economy so there must be some logic behind it.

They are getting onto Energy Harvesting,

ie charging the battery for the Stop Start to save using more power/fuel/emissions and from needing to have larger altenators.

So then there can be Rear electric motors to allow for smaller twin and triple cylinder engines when it comes to Euro 6 & Euro 7 engines and emissions.

(Why Ford are away to have 1.0ltr Focus, & Fiat are going Twin Air & BMW are going 500cc per cylinder. & Triple Cylinder and multiples of.

So in effect KERRS is coming to a road car near you soon.,

which is why F1 are already doing all the Trial Work at the expense of the Far Eastern & Oil states.

Use their money in Motor Sport to design theFuel/Oil efficent next power sources.

Not to worry about the oil rich states loosing out, because soon it is Water that will be more expensive and scarce than Carbon Fuels.

Paddle mode all the time

Never bother with the paddles. Why have a dog and bark yourself?

Given that it's a standard hypermiling technique there must be some credence in the coasting principle. That the DSG box is trusted to be in the right gear at the right time, changing gear in a fraction of a second why shouldn't it be allowed to disengage and coast? Any control input (stop/go) and it can drop back into gear. Chuck in ESP and active cruise control and all the othe mod ons and it'll have a better idea of what's going on soon than the driver.

Why don't you do an advanced driving course and mention or attempt to do some 'coasting' there.

As you're disengaging the drive/control you have on the vehicle manually, you greatly increase the chances of losing control of the vehicle.

I'm not getting into an argument about the pros & cons of it either. If you want to do it, then go ahead, just don't try and brainwash people into thinking it's the right thing to do when it's clearly not. The Police don't encourage it either on their courses and it's an immediate fail if you disengage drive whilst in motion.

Interesting posts here. I test drove a Fabia vRS the other week and one of the things I really struggled with was getting my head around the DSG. Firstly I loved how smooth it was and how effortless it was. I imagine it'd be perfect for carting family about or driving around town. What I didn't like was the gearbox's insentient rush to reach 7th gear; this meant the engine was often no where near its peak power; and with the mention of advanced driving, I've always been under the impression that being in the right gear for the situation is critical i.e. 30mph requires 3rd gear and so on...

I came away thinking that although its a great car (but not what I need) and I'd happily spec DSG into a big lazy diesel Superb or something, but with the Fabia the gearbox just seemed to remove you from the driving experience - which is the reason you want to buy a vRS surely? Getting back in my manual Octavia it was a relief to be able to let it stay in 2nd that little bit extra so you could hear the engine and enjoy the whole experience.

I would however, like to try it again though when there wasn't an obnoxious salesman sitting next to me.

re vRS with DSG,

Forget about usual engines and Max Torque and HP/PS at certain revs.

You are lucky that it was up to 5th by 40mph & sitting happily in 7th by 55 -60 mph.

If you had given it some throttle,

you would have had a Supercharger coming in, then a Turbo with the Supercharger, then a Turbo.

You can be in 5th at 40mph and give it some and be at 120mph very quickiy even climbing a hilll and be in 6th or up to 7th.

It does what it is supposed to do.

It will actually do 50 mpg trundeling on a back road,

it will do 35mpg regularly driving between 55-60- 70 mph.

Boot it an it is down to 25 mpg, as it is usually doing driving around small towns when cold.

Really boot it out on the open road when the engine is warm and you are lucky to get 22mpg.

It is as tame as you want it to be,

But it is never Built to be Economic. JMO.

The DSG just helps with mpg as mentioned above - keeping Skoda's mpg figures within reach

I find it fine pootling around, and as mentioned before Sport and Manual/Paddles are there to help with the fun part...

Do paddles always work on DSG or do you need to put into a paddle/manual mode like some auto's?

You can change up and down gear whilst in full auto. It switches back to auto when you don't change gear using the paddles after a while.

Even when in full manual mode, it drops down itself if you forget to at the lights / junctions etc

D for general day to day, using kick down if i dont need to spare the horses.

M for quick T-juction getaways, as once the steering wheel goes beyond 90deg i can never find the paddles!!

S for engaging warp drive from traffic lights...

What I didn't like was the gearbox's insentient rush to reach 7th gear

S mode will keep the revs in the power band and allow the redline to be reached. D as others have mentioned, tries to save you some fuel.

Edited 5 April, 201214 yr by hertsnminds

Exactly,

and 'S' means it is limited to going up to 6th,

inhibits it totally from going into 7th.

Clearly Advance Driving and Police Driving Instructors would not promote it but they do not have to worry about fuel costs particuarly.

I am ex Department of Transport and had several police traffic officer training sessions with my job. The "not in control" bit is ridiculous as one only has to move the DSG stick a cm or two to move from Neutral to Drive or Sport and this is accomplished in tenths of a second. It is more this antiquated manual boxes where you are depresiing one pedal moving a large throw lever and than releasing this unnecessary third pedal that one tends to be in a pertpetual state of not in control.

Coasting is now being engineered in to the more advanced VAG cars ie the Audi Q range and it will take a fraction of a second for the coasting arrangment to desist if one needs acceleration.

I have probably travelled more than a thousand miles coasting and saved hundreds of litres of fuel. As I have chalenged before show me where it specifically says in which Act of Parliament, which section which sepcifically says coasts is illegal and I will change my behaviour accordingly.

As also stated in numerous posts it is not that you use less fuel in the descent down the hill but you are travelling faster at the bottom of the hill having coasted than if you had stayed in gear as Daiking says, it is down to the inherent mechanical losses when the revs are at 2K rather than tickover. I point you to the study of Entropy and the zeroth, first and second and Law of Thermodynamics for fuller understanding.

Could do with getting in to neutral form the paddles really.

What a load of utter tosh

If you're worried about saving a few pence on fuel, then use public transport or a bike.

Hopefully the responsible drivers here will see beyond all this BS and drive properly. Ex DOT ? Thank God !

Please read your post, especially the last bit ! You're not big or clever.

Utterly boring

Only boring if you cannot understand the technical aspects of this.

Only left Department of Transport to take up my Executive Commission with HMRC.

Civil Service, ie you indirectly, paid for my degree and I have a 2-1 Honours Science Degree, a bit clever perhaps.

Use Hyper-miling techniques, such as quoted in Wiki http://en.wikipedia.org/wiki/Fuel_economy-maximizing_behaviors.

My aim is to travel further and not waste time in petrol stations and pay less Government tax. I have a company fuel card so fuel is only about 50p a litre to me anyways so cost is not the main issue and I like my performance hence two petrol VRSs and a motorcycle that does 0-70 in 5 seconds.

I can Hypermile with the best of them.

I can get a vRS to a true 60 mpg on a run home in the middle of the night keeping to about 45 mph for 20 miles taking the long road rather than the 15 mile road over the hill.

Not going to bother doing it for any length of time with a vRS, but have tried it out,

not up the arse of a lorry where he can not see you in his mirrors,

but at the further back distance where you get the tow

(in the 'eddy' (eddie) which is just like in a white water river in a kayak where you do not need to paddle, other than when you need to break in and out, and like sitting behind a stopper or doing a ferry glide without any effort)

60 plus mpg is safely and easily achievable at 60mph.

In a vehicle thats is the point where if it is raining you do not need wipers on because the air/wind rain is going over the car and curling behind it and giving you tow, you can be almost off the throttle other than a little touch when side winds break the tow.

Believe me coasting down hills in gear saves fuel, but for every down there is an up, and a vRS drink fuel on ups.

(so an extra bit of speed before the bottom of a slope and you may be able to save fuel on the next up, by taking the hill faster and lifting off and coasting over the top, there are many techniques to Hypermile, depending on the vehicle you are doing it in)

The hills i am going down need engine braking and the use of a gearbox to use a lower gear to be safe at somepoint,

to be in neutral and touching the brakes is not my thing..

http://www.forum.dif...pic.php?t=68860

Up to yourself how you save money really.

I would use a vRS to do it though unless you are as anal as me.

I do this and always have done in manual or the vRS DSG. Going down hill you get up to the speed limit and get off the throttle and in the vRS it seems to stay there. I've found it's one of the easiest cars I've driven that flows from bend to bend with little or no throttle input needed and it's a game I play on the way to work where I use as little throttle as possible but still making progress. Obviously when it gets to a hill mpg drops but there's nothing you can really do here. I tend to get up it quickly even if it means a bit more throttle but means I save more in the long run.

Back on topic DSG is great

Drive - most of the time, when not in a rush and wanting fuel economy (got 44.9 on the drive down to WSM! 320 miles on 3/4 of a tank ) overiding with paddles if I want a quick response, e.g. overtaking.

paddles - all the time when wanting to go quickly, keeping the stick in manual, changing gear as you would a manual car...

sport - almost never.. doesn't seem to work in my opinion, it will still be in the wrong gear for a fast drive...

D all the time around London.

Paddles to get my 'lazy' diesel Yeti up to 5th at 30 or 6th at 40 if conditions allow, or down a gear for going down hills.

D for off road use.

I never use sport, doesn't seem to do anything other than never change up to 6th unless you put it into cruise, then it will go into 6th. (no 7th gear for me.) It does change up higher up the rev range, but it doesn't seem to improve throttle response, like on other autos I have owned.

When out of town and I feel like playing, then it is the paddles for me. Also, when on track, I used the paddles.

And my lazy diesel drinks fuel going up hills just like a petrol.......My CR140 is as economical as the 1.2TSI. (or is it the other way around....)
