So here are my experiences and thoughts regarding my 450+ after 30 days. (Former Tesla MX owner)
1. Love the build quality, fit and finish and quiet cabin. The tech is amazing when it works. Charging rate and range is exceptional.
2. Intelligent Recuperation is FRIGHTENING! I hate it. If I am approaching a car at a stoplight in front of me, the intelligent recuperation is slow to respond and VERY aggressive. Feels like you are going to hit the car in front of you. There is no braking as far as I can tell even thought the computer is telling you to remove your foot from the brake! They really need to redo the algorithms for this feature. I also see many similar stories on the net. I gave up on intelligent mode and drive in the strong mode which is similar to my Tesla.
3. Memory functions are weak. The big ones for me are the car does not remember what recuperation mode you were in after parking and shutting down. Whenever you "start" the car it defaults back to standard mode. Same with dynamics. If I set the car in sport mode, as soon as I shut down it reverts back to comfort mode. So you have to remember to make these selections every time you get in the car to drive. This is very low budget. These settings should be remembered in your profile.
4. Wicked blind spots. The car has cameras on each mirror. How about tying these to the turn signal so the image appears on the central screen to see if cars are next to you. My wifes Hyundai does this!
5. Random bugs in software. Hopefully MB will push updates to the software to eliminate these issues. My MercedesMe app says my software is up to date.

Overall I love the EQS and would recommend it over a Tesla X. As the bugs are worked out, it will be an awesome EV.

 

I’ve had my 580 SUV about as long as you, agree with one statement and disagree with another. Yes, your particular settings should be saved and I hate to have to reset the air circulation button every time I drive. We are still using AC here on the Texas Gulf Coast and having the interior air recirculate instead of cooling outside air is a lot more efficient and cools the cabin much faster.

I love intelligent regeneration. I am getting much better mileage with it than any other setting and I drive the EQS as if it is not on. I start to brake as I would on any other vehicle and do not wait for the EQS to start slowing down. It kicks in just a split second after I start to brake. I never want to be dependent on any computer dependent operation.

 

That is good information. I will try that and see if I get better results. I am so focused on that little light that signals when to release foot from brake and let car take over.

 

I don’t look at the light/symbol at all.

 

Me either, I just drive normally using Intelligent Recuperation. I love it.

 

I look at Intelligent Regeneration this way. The EQS gets great mileage the more it coasts or free wheels. If there is no vehicle ahead of you when coming to a stop you can take your foot off the go pedal and coast a lot longer using no battery energy and apply the brakes and the EQS will regenerate mildly. If there is a vehicle ahead of you slowing down for a stop the regeneration kicks in harder to help you stop but by then you should already be naturally braking anyway.

 

Another great feature that Intelligent Recuperation has is that it automatically applies HOLD when there is a car in front of you. No HOLD comes up in the dash display, but it functions similarly.

 

“There is no braking as far as I can tell even thought the computer is telling you to remove your foot from the brake!”

PS-Note that the symbol on the dash does NOT mean take your foot off the brake. It means take your foot off the accelerator pedal. I hate how tiny the symbols are…..

 

Haven’t used intelligent recuperation yet, simply prefer to control it myself so that I know what level of regen is being used and factor that into my driving decisions. Not a fan of surprises at anytime, but especially driving. I will intelligent recuperation a try to see if I like it.

Have been using no regen for highway driving or when I know the road ahead will not have upcoming stop lights/signs for at least a mile or two. Strong regen gets used in the stop and go traffic situations. Normal regen gets whatever is leftover.

Agree with your comments, especially blind spots. Those A pillars are thick! Would love to have the side mirror image displayed on the central screen when using the turn signal. In parking lot situations I’ve found the front camera handy to peak around corners when vision is blocked by the A Pillar, big SUVs, structures, etc.

Also agree on charging rate and range. Really like the relatively flat charging curve. Charging the car now for my first real world range estimate. The car estimate on the charge screen is my range would be over 366 miles on an 80% charge….they need to correct that algorithm! Dealer says wait until 1000+ miles to trust those estimates….I’m not buying it, I think it will still over estimate. But I do believe my real range data will show at least 320+ miles when about 108 kW of energy are used.

 

I think you will find that intelligent recuperation is a combination of no recuperation when the road is clear ahead of you and strong recuperation when you come up on traffic ahead of you that is either going slower than you or that is stopped. It is the best worlds for me.

 

Exactly how I would describe it. 👍🏼

The engineers did a terrific job with this setting. However, I am surprised it doesn’t restore the last used setting when restarting the car.

 

The intelligent recuperation system is also intuitive as far as your speed is concerned. The faster your speed the sooner the system will warn you to take your foot off the accelerator because there is a vehicle in front of you.

 

Results are in. 313 miles. 100.8 kW. So 3.105 mi/kW. Assuming 107.8 kW usable battery estimated range on a 100% charge would be about 334.7 miles.

I mentioned previously how I use regen. I typically target a speed of 10% below the posted speed limit. I also slowly accelerate.

Highway driving was about 2/3 of the driving, and I could see the car using a little more energy on the highway in spite of no regen. I assume this is due to the energy needed to get the car up to speed.

I am happy with the results. I might do a little better in the future because that was a high proportion of highway driving for me. I do feel confident of attaining the EPA estimate of 305 miles on a consistent basis unless it is a long road trip.

 

Holy Toledo….10% below the posted speed here in the Houston, Texas area would get you killed! 😊

 

I have been experimenting with the different recuperation modes but have not noticed any warning about taking your foot off accelerator. Can you elaborate about how/where the warning shows up.

 

It is the symbol that shows up on the dash board. It only shows up in the Intelligent Recuperation mode as you get close to a vehicle ahead of you.

 

I hate to nitipick, but it's kWh (for battery capacity), not kW. (kWh (kilowatt-hours) is a measure of energy - i.e., how much energy your battery contains.)
In contrast, kW (kilowatts) is a measure of power - i.e., the rate at which you're using energy, either when charging your car, or driving it.

 

I’ve seen a few interviews of Mercedes reps (Autogefuehl comes to mind) and the reason regen always resets is because that’s the mode that was homologated.

I don’t have my EQE yet but I figure I’ll just treat it like turning Auto Stop/Start off at the very start.

 

MB could easily restore the last setting by storing with the other user profile settings. They just have to make a simple coding change.

 

Could you explain what "homologated" means in this context?

 

Officially approved. By whom is the question (legal? safety?)

 

For the US or Canada, it would suggest approval by NHTSA or Transport Canada. However, I am not aware of any regulation specific to this type of feature. An OEM can make changes to parts of the vehicle that are not regulatorily controlled at their whim. Those that are subject to a regulation simply have to have that new component or system operation certified to comply with the applicable regulations by their own engineering management. For something structural, for just one example, that could affect impact, recertification is a significant process to meet the requirements of FMVSS 208 as it may involve actual impact testing (or computer simulation in some cases). For others, it could be quite minor or none at all. It all depends on the existence of a regulatory standard for setting a performance level for regen, which again, I do not think exists.

 

I agree 100% with Sportstick's post. If one of the other recuperation modes were in anyway more dangerous than the default 'Normal Recuperation' mode, the other modes would not be available. I'm simply saying the MB software engineers should restore the last used mode by saving it the users profile.

 

I agree. It doesn’t make practical sense to me. Wouldn’t most people expect when they turn on their car that it is set up exactly as it was when you turned the car off. I use intelligent recoup quite a bit and I’ve already turned the car on a couple of times and forgot to change recoup mode and only realized it was when car didn’t stop during first braking episode.

 

So this is the Mercedes rep explaining why the recuperation setting resets at startup:


I guess it makes sense to me why they force it as a manufacturer. But as JoeMa suggested, loading the customer's preferences should override it automatically. If their reasoning is that they don't want to force a customer into D-, certainly a user's own preferences mean they are not being forced into it and actually choosing it.
