Just got 2023 EQS580 SUV








in my case, I am seeing 40-50% range loss in -10C weather and driving in a lot of stop and go traffic or cruising at 125kph. Range is better at higher temps and when traffic is not terrible and/or lower highway speeds.
Also, front clutch disconnect I believe is on the 2023MY. At least I can see that at times it’s just the rear wheels, or front wheels, driving.
Larger batt will obviously give you more range, at the expense of longer charge times.

As for cold weather, it's cold now in the North East (20s and 30s) and loss of range happens. I was asking those with MY24 EQS SUV's how they're doing with range. If you don't own a MY24 (or a MY25) EQS SUV, the question would not apply to you.




None of those changes will make a perceptible difference to range; obviously the larger battery will but don’t underestimate the longer charging time - it’s not a free range increase.
I chose to get 30% off and got a ‘23 vs paying full MSRP for a ‘24.

Anyway, I knew the range would be definitely reduced in the winter here... Nothing surprises, just want to track it and average out for Jan & Feb months, so far it's cold here now.
Will pose the real-time average for Jan and Feb. Still love my EQS, but definitely limited for long distance road trips in the winter.
Just another observation: winter charging is slowing too; average around 60-75 kWh vs 85-160 kWh in the summer. Is this normal charge in the winter or due to new battery? just wait and see.

I have a 24 EQS and a 23 EQE and I can tell the range does not drop in the EQS as it does in the EQE, It’s quite significant.. I don't know that is a fair comparison.

Powertrain Updates:
◯ All-new braking system for improved brake feel with revised regenerative braking software
◯ 4MATIC Disconnect for real-life range improvement on 4MATIC models.
◯ Heat Pump for improved real-life winter driving efficiency
◯ All-New Battery with 118 kWh usable capacity for improved range




Let's go through each change:
◯ All-new braking system for improved brake feel with revised regenerative braking software
Braking feel is not the issue. The real issue is the brakes are far too weak. This is the single biggest flaw with the EQS - the brakes are terrible. Again, it has nothing to do with feel, the brakes are just too small for the weight of the vehicle. Perhaps the 580 is different, I'm referring to the 450. In any case, this has no effect on range anyway.
◯ 4MATIC Disconnect for real-life range improvement on 4MATIC models.
Electric motors have very low drag (reciprocating mass), much lower than gas engines. As a result, I doubt this feature will even be measurable in terms of range reduction. And now you have a set of e-clutches that are repeatedly disconnecting/reconnecting, which is another potential failure. If you look at the power flow, the motors are being connected/disconnected repeatedly.
◯ Heat Pump for improved real-life winter driving efficiency
Maybe, but the main benefit of a heat pump is faster cabin heating. The 2023 model heats up really fast.
◯ All-New Battery with 118 kWh usable capacity for improved range
Yes, but it's going to be a heavier battery, which will decrease range. And again, it will take longer to charge. This may seem obvious and irrelevant but if you've owned an EV and have sat waiting for the batt to charge, you know what I mean. The issue is because it takes 4X longer to charge than it does to use the energy.
In one hour with a L2 charger, you get about 7 kW. That 7 kW is consumed in about 25 km of driving, which you can do in 15 minutes.
So to charge the extra 18 kW, it will take about 2.5 hours, for a range increase of about 50km, or 30 min of highway driving, less the weight impact of the heavier battery.
Taken together, there is nothing here to significantly improve range in winter.

The larger battery pack is mainly improved chemistry, and the curb weight is only 99 lbs. heavier than the MY23 curb weight. The added weight is negligible IMO.
The charge time to 80% SoC for a lager battery pack wouldn't be noticeable when charging at home on a L2. And even if you did charge to 100% SoC, that would happen at night while you're sleeping.
And in the end, only someone who actually owns a MY24 EQS SUV with these improvements can definitively comment on improved range during winter. Not you or I, we're just bystanders with MY23's.
I'm probably wasting my time but couldn't help myself.




Again, it takes about 4X as long to charge as it does to use that energy.
You can assume it will be while you’re sleeping, but not always!








Driving EQS-SUV is best at favorable outside temp's... NOT for the extreme heat or COLD. Of course, I still love to drive EQS so far; there is a BUT right? Yes, but the brutal torture extreme COLD in the last few days, make it very tough to keep up with charges... slow... 20, 30, or 40 kWh per 30-minute intervals vs 60-80 kWh in the summer... efficiency is taking the nose-dive about 1.5-2 mile per kWh... Therefore, trying to keep up with range requirement for daily commutes and errants, I have to charge it two times 30-minutes free charge at EA... yes, I am taking advantage of the 2-year free charge from MB and still NO level-2 home charging (only Level-1 here and there top-up). Just my own 1st year experiences with EQS and MN winter. What's a double-dipper yet!!! Maybe the third one... a glitch warning here and a warning there due to the extreme COLD weather, -21 temp and -40s wind-chill last night... yay. Summary, It's somewhat tolerable ENNOYING yet; just Can't wait for warmer weather.

Heat pumps are all about heating the cabin, and where the heat comes from to heat the cabin. To prove that the impact on range is minor, try this: go into the EQ menu and look at the increase in range from lowering cabin temperature. You will see that you get maybe 1% additional range.
I'm glad that @phillip04S430 pointed out the slower charge time -- it's much slower than in summer!

4Matic models of the EQE and EQS sedan and SUV also get new programming for the electronic all-wheel drive system. The system, which uses dual motors – one on the front axle and one on the rear – now has an all-wheel drive disconnect feature, which switches off one of the motors when it’s not needed. This reduces power consumption with no penalty to traction. Unlike a gasoline engine, an electric motor can switch on instantaneously when needed to power the extra wheels in slippery conditions.

Heat pump: the air-side heat pump in the new model family can utilize the heat generated by the drive system and the heat present in the outside air in parallel to heat the interior. Thanks to its outstanding efficiency, it can significantly increase the range of the battery in colder regions of the world, for example. In this process, the multi-source heat pump draws heat from the ambient air via an external heat exchanger.











Speaking of tech, watch this video of the Electirc powertrain developed by Lucid. Impressive technology:
