New Google Maps Now Worth Using

[MatC21]

I disagree. I aas driving on Swiss/German highway sub-zero and battery barely reached 5 degrees. Only after I was approaching a charger (30min before or so) it started heating to 25 degrees. Pre heating is essential in colder climates.

I grew up in Stockholm! But, yeah, California is nice. I recommend it!

The battery does heat up when you use it, though. There's a reason we have liquid cooling in the battery pack... When you need to fast charge, you've been driving for three hours already. Also, when charging fast, the battery heats itself pretty quickly, so I don't quite understand how pre-heating would help that much.

But I don't have temperature data to back that up, so if anyone has that, I'd be super interested in seeing the real difference, especially depending on ambient temperatures!

Nice!

Well, I’ve been driving at over 110-139 km/h for more than an hour in temperatures below 0°C, and the battery wouldn’t budge from -1°C, or at best just creep above zero. Even then, it’s still essentially useless for DC charging without pre-heating. It’s such a big factor that car reviewers in Sweden practically write off any car that doesn’t have a heat pump. So it really does make a significant difference.

Yes, exactly!

Yes, exactly!

Pre-heating is essential to receive the max charging performance along the entire charging curve. Just driving the car, will NOT heat up the battery. Only if you use aggressive so called yo-yo method it may heat it up while driving.

These are optimal charging conditions, and the car is smart enough not to waste energy and only start pre-heating the battery as you approach the charger, about 30 min or so away. @MatC21 is spot on with his real-world experience.

CCS fast charging station with > 270 kW, > 850V
Battery temperature 77°F
Initial SoC 9% and remaining range < 37 miles

However, if @jwatte would like to do some data gathering and compare not preheating or preheating we can all benefit. I only have a paper copy of the corporate published charging curve, so anyone can try and see how their real world charging aligns with this as best case. The main corporate boast on this slide is that Macan EV is able to use as much as 200kW output at 55% SoC. Has anyone seen this? I wish I could, but my Macan is only arriving this summer.

That's surprising and a little sad. The battery will perform better at 25C, to the point where some vehicles will spend some energy heating the battery to get there. I'm surprised Porsche doesn't do this :-( And happy about the California weather. (Although today it's almost 28C! In March! Crazy!)

This has been illuminating.

Hi @SergeyIndy I have been living vicariously from this forum and the EVKX site. The charging curve they show for all of the Macan variants (as all same battery) is:

The onboard navigation is using Google Maps. What's the difference between the onboard-version and the (I assume Apple) Carplay Google Maps?

The onboard navigation using Here maps and are just adding the Google satellite layer on top.

 

[MatC21]

This is the only charging curve I can provide, was at a Porsche Charging Lounge with pre heating in Winter Climate (iirc around 0 degrees).

 

[TomekGnomek]

OMG not this again

 

[pss]

I was surprised at how good it works. I am a long time waze advocate, so when I saw how well Google maps integrates with display, I was impressed.

I use Waze too.... I wonder if we will see a day when the HUD works with Waze as well.

 

[Greybeard72]

I've been using Apple Maps for my navigation with my 2024 Macan 4 since the Porsche GPS was not very good and Google Maps, among other things, didn't work with the head up display. That has now changed. The latest Google Maps has been updated and improved, and, surprise surprise, the head up display works with it. Definitely worth giving it a try.

Which version of Google maps? I am not getting it on my HUD.. I am not getting it on anything but the PCM display.. Waze at least shows on my dash display. Apple maps shows on both... although the 3d graphics on the HUD showing turns etc. only show with the built in navigation.

I do use Google maps often and directions do show up in the HUD (2025 Turbo). I have nothing against the PCM and it is beneficial of end of travel estimated SOC, the lack of extras such "Police nearby", etc. make it less appealing. Plus the PCM on my 2025 does not provide a "preferred charging network" option when mapping, which is pretty frustrating since I understand is in the 2026 model.
When do OTA updates for such things actually to happen on our cars?

 

[DHS]

As of 4 pm on March 18 my current version of Google Maps is 26.11.1. Google is continuously updating Google Maps, but if you delete what you have and download Google Maps again you should get this or a more recent version and HUD should work automatically. Interestingly, Google is rolling out a bunch of new features, some of which I have and some of which I don't yet have but others do. One is a 3D view (I don't have it yet) and one is an AI feature, which I also don't have. I'm still evaluating the new Google Maps. It doesn't do traffic circles in the D.C. Area as well as Apple Maps, but everything else seems pretty good. I'm not a convert yet, but I suspect Google Maps will be the way to go. Google claims that this is its biggest upgrade in 10 years.
