450e Battery
Headed on our first long trip with this car and trying to plan ahead but what happens when there aren’t any chargers? A quick search shows chargers but they are few and far between. Closest fast charger is close to 150 miles away. Everything else is slow level 2’s and those are rare. If we run out of battery does the car revert to gas? I could kill the battery at home and see what happens but I’d rather not be stuck somewhere.

Absolutely. No worries at all, that's one of the beauties of PHEV. The only thing that I can think of that goes away with an empty high voltage battery is the ability to precondition the interior of the car.

when I drive to my vacation home in the summer I always use up the full EV range in the first half of the trip. Even at 0 miles electric range the 450e operates like a typical hybrid, running on the ICE and generating electric energy when braking and using that electric power for acceleration assist. It can operate this was forever until you decide to plug in and charge.
I never use a charger on the road because the rate is much higher than charging at home.

I would like parato to tell us how far away the vacation home is, and whether he charges once there. I think he mentioned this in a thread last year but it bears repeating to help evaluate his preference. In any case, the black-and-white statement “Even at 0 miles electric…” is good info to know (together with the other replies here).
I do not use up the full EV range in the first part of the trip. Most of my trips are either 200, 700 or 3700 miles. Once I get on the freeway, I change to B mode, even for the 200 mile trip. I’ll use Electric mode once off the freeway. Yes, I have to think to do this, but I don’t like going to zero battery.(*)
On the 3700 mile trip, I have a couple of opportunities for free charging with 3 to 6kw chargers, at the exact place I am over-nighting, so I top up.
(*) It has been noted here that the Mercedes documentation is silent on the 20%-80% battery use rule-of-thumb used by many EVers. Some people here trust Mercedes to manage the battery and are not concerned when it shows 0%, presumably figuring "Mercedes must know!" and noting they still get “typical hybrid” performance. That is good to know, but without long-term data I’m inclined not to trust Mercedes and I aim for 80% charges and don’t like going below 20%.

our first long trip to the boat was today. 60 miles there and another 60 back. We had it in hybrid and in D- and returned home around 9%. In 2 weeks we will head to our beach house at around 300 miles each way with no charger about 150 miles from our house. The house also doesn’t have a level 2 so it wont be easy to charge while there. And in a month we have to drive to Miami so another 1,000 each way give or take. None of our overnight stops will have a charger. Trying to make sure the car can start like a typical ICE car with 0% in the battery pack. Might be easier to kill the car here (at home with a level 2 charger) and see what happens.

yes it has a 12v battery but I don’t believe it has a starter. I think the 48v doubles as a starter. Killed the battery yesterday and even after telling me that system was depleted continued to start on battery if only for 100’ or so. The dealer stated when the battery dies it will run on gas. I realize that is a clear statement the “how” is what I question

I do not know what is required to setup an account in the Tesla networks.
When you go charge your GLE bestie Teslas you will be the rose amongst the thorns.

Any EV or PHEV with fast DC charging can be charged at a Tesla station. This includes GLE 460e with the high speed change option (free in US, extra cost in Canada).
