This begs the question, From where did you get that expectation?

Don't get me wrong—if you've been promised something by a hapless SA and you're seeing significant underperformance, you've got a legit gripe.
I perfectly remember one of the Porsche country managers during the Macan presentation in my city saying: “Macan EV has more than 600km range even driving over 160km/h !!!”

That is something I have not read or heard from anybody. I was there, face to face in front of that country manager.

Of course I didn’t believe him. But between 600 and 350km there is a huge gap to set your own expectations… and fail.

As I said in my post, "I don't think the behavior we should expect at a low SoC has been well documented/publicized by Porsche" and "The changes in behavior people are noting are pretty significant and should not be introduced to drivers by surprise." Please those statements as the full agreement with your concerns they were meant to be.

How a vehicle is designed to behave IS something that's up to the manufacturer. If what you've experienced is "normal," I do think it should be pretty easy to find documentation predicting that behavior. The fact that it's a surprise to you, the people on this forum, and anybody who's searched the Porsche manual means something's wrong—either with the expectations Porsche has set on this matter or with your car specifically. I hope it's the latter and can easily be fixed, but you're not alone, so it looks like Porsche dropped the ball on this.

I'll also repeat my sentiment that people who have been told one thing by a Porsche rep/SA and are experiencing something far short of that have a legit gripe. I was merely suggesting that our expectations can cause us a lot of grief if we let them. It's easier to let them go than change a reality staring us in the face. Offered with all due respect to those who have legitimate grievances and everybody's right to feel what they will. I meant no offense—truly.

Well I have driven the Macan to almost 0% on B roads and had way more range then indicated, but it was not really cold, but power was indeed severely limited. Anyway having such an impact from 10% is just not OK, I can drive my iX normal at 10% … When one is roadtripping you start looking for a charger at 20% to land somewhere below 10%, if this is an issue like it seems to be than I’m really disappointed … That there is battery protection kicking in at around 5% is normal, but this renders the car for me unusable to do road trips, maybe I should upgrade the iX to LCI version and keep the Macan for short commutes.

I read from another forum that Macan drops range to -- when battery temperature is below 6C and SOC below 12%. Haven gone that low yet, but I've noticed that 25% SOC gives you only 50-60km range left when should have around 100km.

There must be a situation of low SOC and very low battery temperature (below 6C/43F) at the same time.Both factors must be simultaneously exist for the performance degradation to be occured.In the video is clearly shown a battery temperature @86F when @12% SOC that's why there isn't any performance degradation.
At least that's the way I get it!

Cheers.

This is exactly how I would expect the Macan to behave in low SOC. First battery warning at 6% with 15 miles/24 km range. Very different from my car, and seems like many other users here also experience the same as me. Hopefully this can easily be fixed (maybe software update?), but at least I was very encouraged by seeing this video. Thanks for sharing @elli

I drove several Teslas before the macan and I’m pretty comfortable driving the battery to 2-3%. On my first roadtrip with the macan I tried to do this like I’m used to, but experienced the same behavior.
If there is 10% battery left you should have another ~50km. But not so in the macan, below 10% the macan seems unpredictable. At 7% it showed me 16km range left. If you do the math, 16/7x100=228,6km so that algorithm seems dumb and not calculating very well.
Hope we get our first OTA soon to fix this.

Yes but, when driving on B roads that, in my case 12km turned out to be much more …
In your case if you calculate 95kwh battery with a 5% heat loss is 90kwh usable at a consumption of 33kwh/100km that 7% would equal to 18km of range … pretty OK …

Ok, so my car has been at the dealer for a week while they tried to figure out this issue. Unfortunately is seems like this is working as intended. After doing some testing, the technicians received a document from Germany explaining how this is designed. They were not allowed to send me the document, as it was Porsche internal, but it is essentially showing how the car is behaving in low SOC at different temperature conditions.

Example 1: At -10°C the battery will under normal driving have a temperature of around 0°C. Under these conditions, the car will go into turtle mode at around 18% (!) SOC, and show 0 range at around 9% SOC. It will still be possible to drive down to around 4%, but performance is severely impacted. This is very close to what I have experienced, and the temperature conditions match the example.

Example 2: At 25°C, the battery will typically have a temperature of around 30°C, and under these conditions the turtle mode will start only at 6% SOC, and the car will show 0 range somewhere around 3-4% SOC if I remember correctly.

So, unfortunately this is how the battery management is designed on this car, which I think is extremely disappointing at low temperatures, and very different from what I have experienced with my previous e-tron. However, at least it is much better to have this knowledge, as I can now adapt based on this and take the required action not to be stuck in a hill in low temperatures at 10% SOC and only being able to go 20 km/h (which happened to me).

yeah, i see the turtle icon...but normal driving...is fine... are you tryign to speed?
only able to to go 20 kmh? ...thta's certainly not my experience

I think the turtle mode gets progressively worse as you get lower. I experienced at around 8-9% that I was only able to do 20 km/h in a (quite steep mountain road) uphill.

Exactly this kind of info, and much more that Porsche holds down, is exactly what customers need to clearly understand how the car works and properly align our expectations.

Thanks for sharing!

This is not good news you guys as more surprises keep coming up with Macan EV. I had no issue driving down to 2% on the Taycan with no noticeable degradation of power. Yes, warning messages appear but it drives normally as I was going 70mph in 0C weather.

Think of this, you get gross battery capacity 100kWh, then you get usable 95kWh, then there is SoH degradation that we do not have any data on, but if we take Taycan which would be the worst case, you lose 10% in the first 10k miles, so say then you have 85.5kWh usable left, and at 20% SoC the car starts complaining, and at 10% left you are limited on power and basically in turtle mode, leaving you with give or take 77kWh usable at full power battery. Well, I have 78kWh usable now on the J1.1 Taycan after taking 10% degradation hit and now at 15k miles.

This is not favorable math for Macan EV, but we will not know for sure until you guys start measuring SoH with hopefully CarScanner and other apps working on it.
I noticed the warning comes on at 40 miles and with poor consumption 2.3 mi / kWh on a brand new car I gingerly let it go to around 14 miles (10%) before charging.

One of the many things about the Macan EV that I'm just not comfortable with.

Another factor: ambient is 2 degrees but battery is 28 degrees. How did it get there? Must be preconditioning. I have to think if the battery is being heated, range will decrease. Why was it heated to above the minimum efficient temperature, I wonder.
