Lower range after E445 major upgrade??
I decided to start a new thread about this potential problem since the thread “EQS recall + Service Campaign” is very long now and perhaps not many are paying attention to much any more.
I’m not sure if it’s my imagination but it seems like I’m getting worse range now than prior to the E445 update. For example when starting out in my garage and a few miles thereafter, I see numbers like 970 wh/mile. It does eventually come down 400 or even in the mid to upper 300s Wh/mile but I don’t recall seeing numbers so high. Temperatures have been rather mild (40s, 50s, and even some low 60s). Yesterday, after I charged the car to 90% with a range of 361 miles, I drove for about 80 miles and the remaining range dropped to 240. Temps were in the upper 50s and dropped to the 40s for the last 35 miles.
Am I imagining this or is it a problem after the major MBUX update? What have you folks experienced?

Go to your phone app after different rides and to the “trip data” section and it will tell you the average KWh used for the last trip and by total mileage on the vehicle. You can compare those numbers with different road conditions and temperatures and see what might be changing. Certainly not the best way but a start….

On my EQS SUV with delivery software version 316 the starting wh/mile value is 1999. It takes several miles to get below 500. In the Summer a 100% charge had an estimated mileage of up to 395. Today with temperature in the 40F range, 100% charge is 292. Last week it was closer to 350. I have not had a software upgrade and the estimated mileage value is similar to yours.

Btw, why doesn’t the inside temperature setting say ECO++ any more? Is this due to the E445 MBUX update? I did set it to ECO on the EQ menu.

This morning I drove about 17 miles with temperatures in the range of 45-49. Immediately after I started the car the wh/mile was 1999 but it gradually dropped as I drove. I followed the speed limit and had the temperature setting at 66. About 13 miles of the driving was at 65 mph on the highway. The rest was at about 35 mph in the city streets. Lo and behold, the range at 90% charge jumped from 325 yesterday to 344 now.

Are there any other new changes result of the new software upgrade to E445? Things such as self (auto) lane change or new games or apps in mbux?

As far as new games or apps is concerned, I’m not sure since I never play games.
BTW, today was an amazingly warm day here for this time of year (mid to upper 60s). My range increased a lot.

No dice! Now, I can’t even find all the options when I press the Climate Menu button. All I see is an image of the 2 front seats with different ways of heating the front and rear seats. I tried everything to find out where the ECO heating options are to no avail. However, when I press the EQ button and then range, I’m able to activate certain energy saving features such as climate control, and a couple others. It does make a positive difference on range.

Tthe poster was asking about the feature in the EQE, that does not exist in the EQS, where the car will initiate a lane change itself. The driver can then allow the change or cancel it by touching the lane change signal or not letting the steering wheel turn. The auto lane change will be initiated on the highway when a lane is open and the vehicle ahead is slower that the DISTRONIC set speed.It can be configured as on or off in Settings.

What is your car listing for max range the past few days? My wife said her range is much lower, and she is right...listing 249 at 100% getting ready for a drive to Chicago today. I've been at the EV business since 2013 and know about seasonal fluctuation, but this seems odd. Car goes from heated garage at home to heated garage at work. I'll watch carefully today to see our performance.

Having now experienced driving in 10F-20F weather, it seems my actual range is down very roughly 30% from when I took delivery of my car at the end of October (~55F temps). I am not surprised. I was expecting something like this based on experiences I've read on this forum and because it reflects what I see when I play with the range estimation tool on MB-Sweden's website (which has a temperature input parameter).
Today, in my local newspaper, there was an article about the efforts to unclog a kilometers-long stretch of 4-lane highway from cars stranded there for up to 22 hours during a blizzard event in my region. People idling forever in ICE vehicles fared well enough. People in EV's, fared less-well. Not a surprise either -- but it brings into sharp focus the extra planning one should do when taking extended trips if there is even the slightest possibility of extreme weather.
The article also discussed typically "overly-optimistic" EV range marketing in general (i.e. range estimates are provided at optimal temps and generally not even with an asterisk referring the reader to impossible-to-read text explaining such). The article went on to mention that Norway has apparently been doing some extensive studies on this across multiple brands/types of EV's and the general finding is a 20-40% reduction in range when operating in sub-freezing temperatures. Of course, "sub-freezing" can mean something really extreme in Norway and I have no knowledge of the details behind this study and the temperature ranges they were using. It makes on wonder if there is a temperature beyond which it would be dangerous in some way to use an EV at all.

You are correct, c4004matic. I'm not stressed in any way by the range I'm experiencing, but it will probably take me a year of driving before I build up the confidence that I understand how to "interpret" the car's range predictions in the most realistic way.

Luckily, the range estimates from MB have been consistently conservative. In addition the range estimator is also consistently pesimistic. As you drive it almost always provides a range in between the lowest and highest ranges estimated when you start your trip, sually right in the middle. If you use the range optimizing tool, you can easilly get the max estimated range but that entails driving at 65 or less. The result of that strategy is owner confidence.

I think the EU estimates are more akin to best case scenario. But, again, the US and EU use different methodology. There is always a fudge factor which is up to the manufacturer. I think smartly European makers fudged down in the US. As far as I know the Germans have consistently underestimated to avoid the bad press that Tesla has earned by consistently fudging the opposite way.
