After several weeks I have now learnt where and how to make good use of eco mode and coasting, to return some excellent mpg figures

Anybody else feel the need to get a cloth?

Great fuel economy if you have lots of time to drive on say a 350 mile journey.

Although I presently have no evidence, travelling down the A140/A14/A12 from Ipswich to the M25 yesterday I achieved around 78mpg.

Yep... Got a bit too excited over that mpg figure...

Oh.. its a little early for that kind of talk.....

'Simply Clever',  if the car is at operating temp and you pull into a filling station and brim it, and then drive about 75 miles and pull into a filling station and brim it and it only takes 4.546 litres or less then you are getting 75 mpg or better, 

any other way of checking is not really 'Simply Clever'. 

 

Or Brim the tank, run it for a full tank, brim again and see how many litres it takes and if you do 750 miles on 10 gallons ( 45.46 litres) 

then you got 75 mpg real world.

 

In a big heavy Seat Alhambra 2.0TDI 150ps SCR / DSG with 6 people and luggage & not even trying for economy & driving @ NSL's it does at least 630 miles for 63 litres, so 10 miles a litre fill up after fill up for the past 12,000 miles, 

and Coasting gives better economy when doing a bit higher speeds so that more time there is 'coasting' & 680 miles is possible for 63 litres (near 14 gallons)

was it all down hill, or a round trip?

When I tried it I reckon it is about 5% more economical. 

That's the figure I got to for day-to-day driving without specifically altering my driving style and exploiting coasting opportunities.

 

If I'm making a point of it I can get  >10% better on some journeys without significantly delaying my arrival.

 

?? 

Was that 75 miles covered from each gallon used day to day?

Was that with a 1.6TDI as well?

Good point - the OP has the 1.6 TDI. 

I didn't buy the VRS for its fuel economy, apart from it being the TDI version of course. But I do like ECO mode with the DSG coasting in some situations for example in traffic queues it makes for a smoother more relaxed shuffle forward. 

Can I ask when coasting is being applied?

There is the 'in the normal course of driving' applications such as on gentle gradients, long distance coasting to slowing or stopped traffic, natural occurrence in traffic flow etc.

Or the deliberate continuous surge and coast method beloved by hypermilers but only practical where there are no other vehicles on the road.

??

American hypermilers usually take the latter to another level with engine kill switches and can get 100 mpg (US gallons!) results with petrol engines.

With the DSG it disengages the clutch when you take your foot off the gas. It re-engages when you apply the brake or right-foot again, or if you tip the DSG into M. 

So it could be used as you suggest. 

I don't like it for normal driving and the lack of engine braking takes some getting used to. 

Only when the throttle is lifted (foot of the gas)  and momentum / speed can be kept and there is no load on the engine, so not always does D 6 or D5 disapear and it just shows 'D'.  So often it is downhill or on the flat.

Hi, it is not that I feel I am trying to get the highest mpg, but more that after getting to know the car, I can tell when it feels correct to allow the car to coast to the next junction or allow engine braking, if I feel I need engine braking then instead of braking to get it to engage a gear I pull back on the stick which knocks into sports and Into a nice low gear, then pull again to go back into economy were it usually goes back into coasting if you are still moving and want the extra momentum. It  might all sound like it's a lot of messing to get more mpg but to me I now do it without giving it much thought.

 

I was behind an astra the other day for about 5 miles, he must have hit the brake peddle at least 50 plus times and I only pressed mine once when we eventually got to a roundabout, but the main reason I could rely on coasting and engine braking was from keeping a safe distance to the cars In front unlike the astra driver. I would also say this is one of the Main reason's I have never been involved in an accident or made an Insurance claim.
