Does it actually do anything?
On my latest car engaging it just seems to make it more sluggish. Is it just for motorway driving as on normal roads any benefit it gives must surely be outweighed by having to drive it harder?
Under what circumstances would it give increased mpg?
On my M140i it made the throttle pedal less responsive, switched off the air con so the windows kept misting up and put the gearbox into neutral to coast every time you were off throttle. It also displayed an "eco-meter" on the dashboard to tell you every time you accelerated harshly or went above 55mph.On my latest car engaging it just seems to make it more sluggish.

I think I used it once so don't have any definitive data for the MPG saving, but it certainly sapped all enjoyment from driving

On a run, my 335D gets 5-10% more miles if I use Eco mode...and I only use it when I'm doing long motorway runs where I know I won't need instant blasts of acceleration to overtake.
That's according to the little eco savings display on the bottom of the dash...so don't know if it's true or not, as I rarely do a full 600-700 mile run with it on.
It's about a similar saving between keeping it in Sport vs Comfort...but Sport holds gears longer and tends to stay in 1 gear lower all the time...so the extra revs will account for most of that MPG loss.

On some recent Ford’s I’ve driven it dulled the throttle response and also deactivated a cylinder (going from 3 to 2) when driving at a steady pace. Stop/start at lights etc. Did return a better MPG but not something I was wild about using. On my latest car engaging it just seems to make it more sluggish.

On my 335d, there are a few rare occasions when it may give a gentler drive. It does not do anything economically that you can't do yourself. It does have a coast function, but you can turn that off as it just feels wrong. I just use the normal comfort mode, and knock the stick left when I want sport mode. I use sport mode on some winding and undulating roads here in NW Wales, that gives more suitable control in those conditions. But Eco mode? - no I don't use it.
On my SLK55 I find it doesn't help on motorways. I get the same mpg in 4 cylinder mode or 8 cylinder mode.
There is so much torque that it's running very low revs at the speed limit on 8 cylinders.
In eco mode, the throttle response is sluggish and on a slight incline you have to use a significant throttle to keep the speed.
However, in town driving yes eco mode would help but I bought the car because of its V8 so I like to just run it in that mode

I haven't owned a car with eco mode yet, but in the rentals I have had (there have been many) the eco mode tends to reduce response, reduce Aircon power, reduce seat heating power, change gearbox mapping to stay in higher gears, display things on the screen to encourage gentler driving (gamifying eco driving) and sometimes closing flaps in the front of the car for aerodynamics.
It seems to make a tangible difference and it is not how you want the car to be set up all the time, so it's generally good to have it as a mode rather than a default.

On Volvos it makes the displayed mpg rise markedly but steams the windows up.
Maserati ICE mode lifts the mpg by about 10%
Mercedes didn’t seem to affect MOG
All make it very difficult to pull out of junctions due to delayed throttle response and selecting too high a gear.
Does very little on manuals.

The first question reminded me of a Clarksonism He was testing a Bentley GT which had 5 mode settings for the driving style and said that none made any discernible difference.On my latest car engaging it just seems to make it more sluggish.

I'm a big fan of eco modes.
On my M140i auto I had it made decent savings on my motorway commute, often seeing north of 50mpg.
Of my current cars:
The i3 rex eco mode mainly softens throttle response which I actually think makes for a smoother ride and it has a soft limit to 75mph (which you can hard press throttle to override). This adds about 10-15 miles to the range which for me is the difference between getting to and from work on electtric alone.
On the X3 m40d eco mode again softens the throttle response and improves mpg only because it removes the fun! But on the long motorway commute I have that's no bad thing.
On my mustang..... don't be silly!

It would appear it does something by making the car sluggish. There's probably more going on that you don't notice, but the acceleration is what you've noticed.On my latest car engaging it just seems to make it more sluggish.
