Definitely an underrated new feature of this car. I definitely agree this is most likely the smoothest start-stop system in any car at the moment. I experienced this on my test drive with the GLE53 and it was a wild experience. I have the start-stop feature on my w204 and obviously it is a bit jerky so I have a method of quickly tapping the throttle to wake up the engine and then pressing on it drive. This muscle memory kicked in when I was test driving the GLE53 and the instant I stepped on the throttle the car quickly moved forward with the engine still off. I was not expecting that kind of instant response. The other benefit from what I've heard is that the AC continues to run even when the engine shuts off thanks to the battery which is kind of a big deal during a hot day. When it's too hot I usually find myself turning the start-stop off in my w204 so the AC doesn't stop running. Can't wait to take delivery of my new GLE to finally use this feature in its perfected design.

Glad it's working for all of you 450 owners.
It sucks so badly on my 350 that I permanently disabled it.
The A/C draw on the battery down here in Florida makes it start again after 10-15 seconds every time.

Are you taking only short trips, which will not fully charge your starter battery?
If so, either drive an hour or so at least once a week, or get a battery maintainer. That should get your time between starts increased. If you don't you will shorten the life of your battery.
This won't help the fact that you don't get cooling with the engine off, and that's true of every vehicle out there, except ones that have 48v or 72v systems to drive the compressors. (or electric cars) Maybe that's why M-B placed the S/S disable button a finger width away from the start button.

I think a lot of people don't realize how bad it is when you live in a climate, where you use the A/C 360 days out of the year. Plus my 350 has the lurch issue, where when the engine turns off and on, the whole car jumps forward a bit. Honestly, it's embarrassing when I have passengers in my car, as they are impressed until then and ask if something is wrong with the car.

I don't know of a manufacturer that doesn't have Stop/Start as the default setting - thank CAFE. I applaud M-B for making it so easy to disable.
I'm not familiar with the Lurch Issue. The 350's I have driven didn't have that issue. Hope it gets solved for you. Do you use the "Hold" feature?

I sincerely appreciate your input and explanation. Yes, the A/C is off when the engine is not running and that alone is a reason to disable the SS function in South Florida for at least 8 out of 12 months of the year.

Well, the 4-cylinder OM 654 M diesel and M 254 gas engines now have the 48V ISG, only not for the US. They are available in Europe on the E-Class.

As for my GLE's start stop system, after having had the car for about two years now, the start-stop doesn't really kick in very often now and makes me wonder if the battery has issues. Happened on my old c250d (w205) and might be due to my relatively short inner city driving.

I've had a 2020 GLE 350 for 2 years and the start-stop was terrible as users have mentioned above. I'm also in South FL. I got in the habit of turning it off as soon as I started it up
Yesterday, I traded it in for a 2021 GLE 53 and the difference is night and day. Wow, what a difference in that feature and many others.
