Hej, the function “sailing” in the ECO operation I first assessed a bit critically, because I was not used to it and in the last years with the old Volvos simply “invented” my own way of driving sparingly. But if you get used to it, it will be so that you can drive even more economically – because you simply have to drive much more forward-looking. However, I have a topic with the function however. Really practical it is in my opinion mainly on country roads – especially with the speeds announced in the combined instrument – or in Sweden, where already a few hundred meters before the place table is a hint, that soon 50/40kmh – you can take the foot off the gas and sail to the village. Motorway rather less, because you drive there in the best case anyway with Tempomat, with Tempomat there is not this function. But what I noticed on my holiday trip by now – at higher speeds (which I drive as an Austrian only in DE) – so >120kmh I guess – I did not have the same thing at the time “kuppunk” – I did not have the same thing.
