Eco-Engine Change

[JoshS117]

One thing I've noticed between the old 2013 version of the DS3 and the new 2015 version is that the eco start stop engine doesn't kick in until the car has completely stopped. the 2013 one turned off when it was rolling out of gear from around 10mph. I did like the older version rather than new as it felt like I was saving even more fuel (sad I know) compared to now.

I Eco Roll when I can (2014)

Our 2014 lets you do it, I thought it was an oversight TBH as rolling out of gear with no vacuum pressure always seemed a bit weird/possibly dangerous. Though I've not tried to see if the servo assistance on the brakes still works after the 1st press.

Coasting ("rolling out of gear"), apart from being illegal*, is not good practice as it reduces the control you have over the car.

If you're doing it to save fuel you're wasting your time - in fact you're using more petrol! On the over-run the fuel supply is cut off, so you're not using any fuel; in neutral you're burning fuel to keep the engine running.

*To the best of my knowledge.

the engine comes back on before you lose your brakes

With stop/start the engine is off when coasting as described above though ? We put the car into neutral and then below 10mph the engine switches off....

have you even read the thread.

Ah fair enough it's one of those things I've not really wanted to experiment with incase it didn't.

Maybe I misread the original post, but that does sound like coasting to me! If I'm wrong, I apologise.

If you want to be that Eco buy a bicycle.

It's most likely a software change to the car which has changed the nature of the system.

Just to add to my comment above

When I'm sat on the M60 doing under 10mph surrounded by other cars doing the same speed there's not much more control I need other than to slow down even more and stop!

I don't eco roll on open roads when ever I can, just coming to a stop at lights, sat in traffic etc. And its never to save fuel, just because I'm slowing down anyway.

[Bigfeet]

The "Eco-Roll" was part of the software to allow the user to "change their mind" when coming to a halt, the idea was that you are slowing down to stop but then an opening appears to continue.

[JoshS117]

I just found it good when on the commute. as WTF says useful when coming to red lights. slow moving traffic and when on a slight hill just to roll.

Relating to bikes I'd rather not be one of those folk. Mountain biking fine. Road bikes. NAAAAAR
