The rest of us are. I also own an Avalon Hybrid and the GLE 450 is just as smooth and quieter because unlike the hybrid it's not required to make artificial noise when running on battery.

The dictionary defines seamless as: : having no awkward transitions, interruptions, or indications of disparity. Perfect/Flawless.
I think we use words differently.

I leave it on, in both my GLE350 and GLS450. The GLE is certainly more rough, but I've driven just about every other rental vehicle that has this feature, and MB does it best, of all the ones I've had the dis-pleasure to rent for business.

It appears the 48volt (EQ Boost) system allows for this seemless transition. So those that have the 48 volt system and claim "seemless", it is in fact, "seemless".

The 48 volt system runs the AC as there are no belts. Therefore, the AC stays nice and cool even with the motor "off". I believe the big difference in opinion of the "start/stop" feature is those that have the 48 volt system and those that do not.

Not sure why you seem to think that those of us who have the 450s with the 6 cylinder engine and the 48 volt battery don’t know what the word seamless means, but by the definition you posted, our GLE 450 is indeed seamless with the start/stop feature. I don’t even notice it at all, and since I don’t actually stomp the gas to the floor the second a light turns green, the start and acceleration is indistinguishable from leaving the engine running. Any time we have someone in the vehicle they are usually amazed that we have the feature turned on.

and in my GLE450 it is seamless. My previous GLE43 and GLE350 without the 48V system was not seamless at all.

When you say seamless, do you really hear/feel nothing at all? In my 450, when the light turns green and I let go of the brakes, I usually "feel" a very slight vibration when the engine starts back up.

The acid test would be someone who had never experience this stop / start and ask them but as I didn't notice it in the first place I think that proves it.
I suppose its a bit like asking if your watch is silent. I can't hear mine tick at all but in a quiet room with my ear to the watch I am sure I could.
For me it is seamless and I find that quite incredible especially given my previous experience.

No nothing at all. I'm not paying that much attention to be honest and the first time I drove it I didn't know it was even on. Having come from cars where it is noticeable I was very aware of the difference. I am sure that if I really concentrated I could "tell" when it had restarted but in general day to day use I would say it would be seamless.

Interesting. The article says, "The ISG...enables Mercedes' "gliding mode," where the engine shuts off while you're coasting with zero throttle input to save fuel." I didn't know this was a feature. I'm wondering, if you push the button to turn off Start/Stop, do you also lose "gliding mode"?

Any way of making ECO mode the default setting? I leave the auto start/stop on because I want to save on fuel. I do sometimes forget to put in ECO mode until I’ve been driving for awhile. Car seems to be less abrupt in ECO mode. Just came back to NYC from driving round trip to Florida, cost for premium fuel down south can be as high as $1 per gallon more than regular. Up north the two grades are usually a $.30 - $.40 difference. Tried to fill up at Costco, not always convenient .

The vehicle will turn the engine off and coast, not using power, nor charging the battery. (If you’ve got the 48 volt battery, it charges it whenever you use the brakes.) It’s most noticeable when you have the start/stop option left on and eco mode is also on, and you are heading down a hill and not touching the gas or brake, but it also does it in other situations where you don’t need gas or the brake.
