Standard Range Plus Supercharging Speed

That would be at ~63 mph:

Tesla must test at ~65 mph for highway... or at 50mph but with AC load or something...
I'm able to get about 255 watt/mi at 70 mph which would be good for about 196 mi, but that's usually with AC off and gentle driving and steady cruise speed.
No, not at all. These are industry standard tests done by Tesla that meet the EPA requirements and are defined in SAE 1634. Here's more info on the testing: Detailed Test Information
The 247 mi result is with an SR+ on aero wheels doing the standardized test regimen.
Average speed of 21 mph! That makes a lot of sense. I often see ~160 watt/mile when I'm down at those speeds (been using residential side streets since they've been repaving the main roads and I don't want tar on my Model 3.) At 160 watt/mile my SR+ would be able to do over 300 miles
The 48 mph "highway" is just stupid. Maybe they're trying to recreate a LA freeway or something, but I would rather see a cruise somewhere between 65 and 75 mph for the highway speeds. I think most American's think of highway as a road trip on an interstate for a couple hundred miles. I probably could get near 240 or 250 at ~50 mph so that makes sense there too.

The average of the city and highway are typically derated by a factor of 0.7. This is the relevant section from the EPA docs at https://www.fueleconomy.gov/feg/pdfs/EPA test procedure for EVs-PHEVs-11-14-2017.pdf

On Tesla's Q3 earnings webcast yesterday, it was confirmed that SR+ Model 3s will be receiving faster Supercharging speeds. This will likely come with the powertrain firmware update in a few weeks that was discussed, increasing range and power by ~5%.

Model 3 SR+ officially upgraded to 170kW Supercharging with 2019.36.1.

That’s amazing. I think that’s almost exactly what we’ve been calculating here. I think 168kW is about what everyone estimated SR+ should be able to do on V3 and of course maxing V2 at 140 to 145kW. It’ll be REALLY interesting if it’s able to maintain that peak along the same curve as it’s software limited 100kW (basically 5-55% SOC) or if the taper starts much sooner...
I look forward to data from here and a ABetterRoutePlanner...
The taper will be the same profile (knocked down for equivalent c-rate) as the LR batteries. The initial taper point will be at about 25% SOC under ideal conditions.
Here's a chart repeated from higher in this thread:

Here's a chart repeated from higher in this thread:
That profile on V2 looks like it’ll shave about 4 minutes off from ~4% to 52% SOC. 24kWh in about 10 min 30 seconds compared to the current ~14 min 20 seconds. That’s a pretty nice improvement for just a software update!
V3 doesn’t seem to offer much of an advantage since it looks like the same range would be roughly 9 min 50 seconds... so a 40 second faster charge...
Unfortunately the release notes for 36.2.1 skip the part about supercharging increase to 170kw! I just installed and it is NOT there.
I feel like I just walked into an April fools joke.

Give it time. They probably encountered some bugs with the faster charging and temporarily pulled the feature.

technically there was never any official release note for V3 on LR models either. You should stop by a supercharger to see if it works or not

Nope,I just noticed somebody’s post with release notes for 36.1 showed a paragraph describing the 170kw that is not in my 36.2 release notes. Would love to see a new charge graph.

Well, if Tesla assumes you had seen the old update, there is no change from .1 to .2
Or might have been pulled back. Just test on a Supercharger and make a video and share it here

I thought the same, that tesla's release notes did not repeat already deployed updates. However, my car went (yesterday) straight from 2019.12.2 to 2019.36.2.1 and there was no mention of 170kW peak.
I'm guessing they pulled it back, temporarily due to the fact that my car never displayed a note regarding new 170kW peak. Thus, me as a user never got that info from Tesla. Let's wait and see, Christmas probably.

Did you try it? Like I mentioned above, LR owners never got a release note saying 250kW V3 charging was now supported. It was only in an early access build.

Several people around the forum with 2019.36.2.1 have tried Supercharging their SR+ and have found the 100 kW cap is still in place, unfortunately. One guy on Reddit even tried it on a V3 and still only got 100 kW.
They've pulled the 170 kW since 2019.36.1, hopefully they fix whatever the problem was and bring it back soon!
