Wow! Not quite LEAF speed but fast. The irony is Tesla needs to heat its pack to charge faster while Nissan needs to cool it to charge faster.

Which is perfect for roadtripping where the built-in Route Planner knows you are stopping at Superchargers (waypoints).

Tesla page (https://www.tesla.com/blog/introducing-v3-supercharging) quote:
On-Route Battery Warmup
New Supercharging infrastructure isn’t the only way we are improving our customers’ charging experience. Beginning this week, Tesla is rolling out a new feature called On-Route Battery Warmup. Now, whenever you navigate to a Supercharger station, your vehicle will intelligently heat the battery to ensure you arrive at the optimal temperature to charge, reducing average charge times for owners by 25%.

They could be allowing a deeper discharge. They could have tweaked something to make the drivetrain more efficient.

What, specifically ? Certainly not cell discharge below 2.6V.
And why would it not extend to the AWD or Tesla MR ?

I don't know what specifically because I don't work for Tesla nor have inside knowledge. My point is that increasing the max cell voltage (as you suggested as an authoritative test) is not the only method by which they could extend the range (and keep in mind, I agree with you that this is probably more a sleight of hand/code than an actual range increase). In fact, increasing the max cell voltage is probably somewhat down the list since there is probably little headroom and that would probably be the most risky method to use.

But yes, allowing the cells to discharge to a point 0.5% lower (back of the envelope would amount to about 6mV) would be an option, as would other measures like less aggressively managing pack temperature or a whole host of other things like more efficiently running controllers. It is not out of the realm of possibility that Tesla has been gathering data and finding places where they can tweak efficiency or allow certain parameters to exceed their original specs (including both max and min cell voltage).

The more I look at the budget the more the 2018 SV fire sale looks like the way to go... It's enough range under warranty for 8 years and I don't have to spend $1500 to get a color I like.

But then you get to spend that amount *again* in 8 years. And at least for the first 8 years you have a hobbled car that is only good for local duties.

I don't see the value.

I don't see the desire to keep an 8 year old car that is part of emerging technology. I guess we all have a blind side.

Not as true as it once was. Seeing 40 kwh packs dropping charge like crazy while accelerating uphill on very cold days only to regain that power on the downslope. IOW; SOC (yeah not a typo...) going from 60 to 20 to 55%...

Sounds like yet another BMS bug.

Is "emerging" the PC way to say POS when discussing the LEAF ? Because I assure you, my Tesla is a wonderful car today and I expect it to be a wonderful car in 8 years.

Right, opposite ends of the spectrum.

That would hardly surprise me. The BMS/LBC is crap.
