Given your name, you may want to correct your units of measure. I'm sure that others will bring them up.
Lol. I wonder which ones? I did make a mistake with the power per unit of mass: it's 170 W/kg. The other mistake is that one has to leave a space between numerals and the unit of measure. Anything else I missed?

I assume that you meant a "90kwh pack."

Indeed i was referring to 90 kW charge power not 90 kWh battery capacity.
90 kW is the "minimum" that a Tesla supercharges at. 150 kW is the max for M3 of this generation. Tesla is looking at technologies for even faster charging powers.
The only time the power decreases is when its approaching full battery. IDK exactly the curve but nothing I would be worried about. I mostly supercharge to 90%.
At home the max is 48A @ 240V which is 11.5 kW. As I mentioned earlier I only use my "old" Siemens charger which puts out 7 kW and is enough for our daily needs. I frankly don't care if it takes an extra hour overnight to charge.

I am hearing the Audi e-tron on EA ccs chargers can beat Tesla in charging speed. A Tesla is more affordable of course.

Back on the 2019 LEAF thanks to EA we get in the 70s, I heard a rumor EvGo was finally deploying 100kw Chademo if that is true I hope a LEAF plus tries it so we can see what the real max charging speed of a LEAF Plus is. One of the forum members here thinks they read in the real world that the LEAF Plus maxes out around 80kw in the real world. I have just yet to run into anyone who found a charger fast enough to test it. Around 75kw is still not bad to me. I have had people (who have never driven an EV) claim (to me) that they require less than 15 minute charging to get back on the road. I try to tell them that most of their charging could be at home so it does not take any waiting at all but then they are like that once a year road trip. I am like have lunch, take a small walk.

We have 100Kw CHAdeMo EVgo as well as EA pedestals in our neighborhood, and the LEAFPlus gets about 75kW at best from both of them.

Thank you! I was hoping someone around had tried one of the new EvGo 100kw I had heard existed.

That seems correct from what I read. Apparently they did away with the throttling near full battery and although the Tesla has faster speeds, overall the e--Tron finishes faster.

However, I supercharged 4 times in the 2 months we had it. It's a breeze. I'm not at all worried about whatever difference this makes. Tesla's Supercharger network puts everything else to shame at the moment. No matter what the e-tron can do it will take a long time to build a ccs network to beat Tesla's. I simply can go anywhere without worry just like having an ICE car.

The onboard computer even tells me how many chargers are occupied/available. When I tell it to navigate to a charger it starts conditioning the battery (whatever that means) to prepare it for supercharging. It's night/day difference from the Leaf.

The best o have seen anywhere posted is 78KW. I have only achieved 76, but want to try again with the car below 10% actual and ideal temp.

My record is briefly 77 on a plus on an EA.

EA has been building faster than Tesla for now, most of that is because of dieselgate not just because they want to push EVs like Tesla. Tesla of course still wins as they can use superchargers AND EA, Evgo, chargepoint etc.. One bit of feedback to give Tesla is please release a 100kw Chademo adapter as you will charge faster which gets you back on the road faster and of course being charged by time it helps to get out sooner.
