@jedc1 and @lucky 777 Ladies, Please! Take this stuff off line. Use the PM feature to throw barbs.
I had some ideas about Start-Stop but I can't find a way between the contestants.
(BTW there is no stuffed Panda for the loser.)
Thank you very much.

<<<<<All I said (and I stand by it ) is that the stop/start feature doesn't seem like auto manufacturers' best effort at improving efficiency, economy, and emissions for their vehicles. <<<>>> And that automakers in general could probably come up with better ways than this feature to improve efficiency. <<<>>>
With this new "500cc per cylinder" architecture (4 cyl = 2.0L, 6 cyl = 3.0, 8 = 4.0) they are approaching 50% thermal efficiency, heretofore unheard of. Their Formula 1 engines have exceeded 50% for a few years now, and we see that tech filtering down to the new production engines, particularly in the AMG53 variants.
The I-4 and I-6 engines will be more efficient than the V-8 because of a variety of things, like internal friction and intake / exhaust packaging.
I am mightily impressed with the 33 mpg we see regularly on highway trips. Not bad for a 2 1/2 Ton do-it-all vehicle!
Some say that, if I.C. engines can achieve 55% thermal efficiency, they will surpass pure electric vehicles for overall efficiency, all inputs included.

I read somewhere on this forum just the other day, I think I was in an AMG thread, that maybe someone had discovered a way to enable or disable it through the OBD. I didn’t pay it much attention because I’m not to fond of doing things like that. I’ll see if I can find it again.
Maybe someone else read it too and can remember where it was.

In addition, where the 4cyl completely disengages the driveline and you coast with no engine braking (in eco mode), you get Regenerative Braking with the 450/580, during decel or mild braking. It's actually quite smooth, and I kind of like that feature.
In fact, with our 450 I left the S/S feature enabled because it's so well integrated. More - at lights or prolonged stops, all features that would normally quit operating (water pump, Air Conditioning, etc.) are active - driven by the 48v system, so you don't lose that function.
In real world driving, I get +3mg on the 450, compared to our '19 GLC399 with the 2.0L four. I'm good with that, especially since the "start" part is pretty unnoticeable.
However there is a current thread about a provider named Vlad, who can provide programming to change the setting default to "disabled" all the time.
Edit - here's the post with Vlad's pricing - https://mbworld.org/forums/gle-class...ml#post8236531

I've absolutely hated the start/stop function on every vehicle I've driven, I paid for a mod to disable it on my wife's VW Tiguan. I have grown to love it on the GLE450, as others have mentioned, its barely noticeable and it does improve the fuel economy so I've left it on. I purchased a bunch of options from Vlad but I left this one out because its so well implemented on the 450 there is no need to turn it off...

mjs, it is definitely not smooth. My 2017 E300 was smoother, but not exactly polished. it was very unobtrusive on my 2019 E450. I think the small engine/big vehicle makes it harder to conceal. Also - the E classes used to start from a stop in second gear in Comfort mode, which I think minimized that "jump" you describe - the GLE350 starts in first gear in Comfort mode, which I think makes the "jump" more prevalent.

We have the 350 and the stop-start is annoying as hell. Thus, from day one of ownership my wife and I programmed our starting procedure to include pressing the override button located right next door to the start button. We do it so systematically that we never even think about it. You could do it too, NBD.

Vladimir from Belarus is The-Guy on OBD programming - you Plug-In his OBD dongle - go thru simple steps - and the result is your Eco-Start/Stop your Mercedes will start-up with the Eco-Start?stop setting (On or Off) that you shut down your MB with. The mod gives you Control/Your-Choice on ECO

If you are competent with electronics or know someone who is, you might be able to adapt this to the Mercedes start stop switch http://www.evilution.co.uk/index.php...trical&mod=674
All it does is send a switching signal when the car is started like you have pressed the button to turn it off, if you wish it to be on you will need to press the button after starting, it just reverses the process that most manufacturers have forced upon us.
I have this in my Smart car and it works great, I have not put it in the Wifes Merc as she likes the feature.

We've been providing an installed Eco Off solution for quite some time, and now also have an OBD programmer solution available that recalls the last Eco setting you had the car in.

I assume this should also work for the 2021 GLE 53?
Also by ECO setting do you mean the Drive setting so that it doesn’t automatically reset to comfort mode or is this the Start Stop?

For anyone annoyed with disabling the start / stop feature each time, you can pick up one of our OBD programmers that retains "last mode" for this feature, you can take a look at our vehicle coverages HERE. Pick one up today!

I really hate the start/stop feature and feel this was worth it to me. Although the 48 volt system isn't as jarring, I don't like the feel and also the wear and tear, and voltage drop are a concern.
The instructions were a bit unclear though. There were some sequences to open and close doors, and switch ignition on off, then on, then insert adapter within 8 seconds. There was no way I could reach blindly under the dash with the door closed and insert the adapter. I opened the door, plugged it in, and It seems to work perfect, but I did not get any indication or conformation on the screen. Now when ever the drivers screen is on, there is an "A" in a circle that always says OFF (unless I toggle it manually with the button near the ignition switch). If your model is listed, this works.
