I test drove a 2023 GLE 450 which has a standard 48 battery EQ system. The engine idle stop/start is seamless to me.

I just wanted to know if 2024 GLE 350 will also be equipped with the same system. If not, I will pull my trigger to buy a 2023 350 now.

Thanks.

From MBUSA:

"Thanks to mild hybrids with 48-volt technology and the Integrated Starter Generator, as well as the new GLE 450e 4MATIC plug-in hybrid, the entire GLE model range is electrified."


Surprisingly, the 0-60 is only spec'd at 0.1 seconds faster than the current one, but I expect electric motor will be felt across the range, and better start/stop system.

Mercedes has a tendency of including a "marketing influence" on their 0-60 times. Basically they are not accurate and I am guessing that they don't want to influence sales of their upper trim levels. By way of example, the 2021 E450 is advertised to do the sprint in 4.9s but measured by a number of sites at 4.4 and even 4.3s. That is a significant difference (at ~55mph in a half a second it travels 40 feet - the E is 190" or 15' so that is about 2 and a half car lengths).
I am guessing in reality, the 2024 GLE 350 with the 48V system will do better than advertised.

Yes, the 2024 GLE 350 will be equipped with the mild hybrid 48 Volt system as currently on the 450. The start/stop will be seamless, and it can coast with the engine off ( you will still have power steering, brakes and AC as the are now electrically driven — no belt). It should get better MPG also.

However, in 2024 the are also building a GLE plug in hybrid (strong hybrid) - I think will be called the 400e. It will have the same 4 cylinder as on the 350, but will have a large electric motor and battery (much larger than what will be on the 350/450) that can power the car on its own - can be driven as an electric vehicle. It should have an all electric range of 40-50 miles before the useable charge in the battery is depleted and the gas engine cuts on, at which point it will operate like a normal strong hybrid (think Lexus 450h). On a road trip, you just put gas in it and drive until you can recharge the battery. The combined power (engine + electric motor) will be close to the output of the GLE 450 - similar acceleration times, but the gas mileage should be much better. If you drive less than 40 miles/day, you can recharge it at home overnight and you will rarely need gas.

Thats the model I will be interested in.

I would be very interested in the strong hybrid as well, seems like the best of both technologies. Probably not the first model year though...let them work out the kinks.

I think that the BMW X5 50e is a much better offering than the GLE400e. I would much rather have a hybrid paired with BMW's smooth I6 than the buzzy Mercedes 4 cylinder.

That would be the GLE 450, but it is a mild hybrid. On the Plug in, the engine will be off for most of your daily drive, so it will be EV quiet. The only time it will be on is sustained Highway cruising once the EV range is depleted. You really can’t hear the 4 cylinder at cruising speed, and even when the battery has used up the EV range, it will still have a charge and the electric motor will assist the engine during acceleration. Yes, there will still be times under hard acceleration you will hear the 4 cylinder in all its glory, but it shouldn’t be that often if you charge it every night. So NVH wise, the majority of the time I suspect the GLE 400e will be better than the GLE 450. .

That said, I see you have the GLE 550e, which I understand has ~15 miles of EV range. When it still has EV range, does the engine stay off during normal acceleration? I understand the 2024 GLE 400e will have somewhere between a 40-50 mile all electric range, so it should be an EV the majority of the time unless you drive more than that a day. I assume if you floor it, the ICE will kick on and you'll hear an I-4, and not an I-6...but it is extremely rare that I've had a need to floor my GLE-350.
