No problem. I love a mystery. I see you dug up the MT testing article that does mention 'high desert' locations multiple times. They use corrections that improve times on ICE cars in hot, high altitude conditions, and the article mentions they use smaller corrections on hybrids. And my guess is that they use no corrections on pure electric cars. But I doubt whether they apply corrections the other way, cutting back electric car performance from what is measured in hot, high altitude conditions, where air drag is lower. But in that case their tests would produce artificially good numbers.
I hope Its the current vs the voltage drop as you suggest. If the improvement is because of lower voltage drop, that may indicate that the 90D battery is fundamentally more capable than the 85D battery......which is certainly plausible.
And thus the P85DL is at the limit of its performance.
If increased current is the only factor, I would expect/hope that the P85DL may also achieve the higher powers since we now have the fuse and contactors to support these currents.....at least that's what I thought the L upgrade was all about.
I suspect we will know soon.
You bring up several good points above.
When I saw that they clearly recognized that correction factors would need to be reduced for hybrids, it made no sense to me that they would use standard ICE correction factors for a BEV like the Tesla, which is what I've seen some in here suggest.
The consideration of high DA being an "advantage" for any drag vehicle looking for best times, well I'll admit, is/was strange to me, having been conditioned to favor low DA for best results.
However in seeking the best quarter mile time, every little bit is a help.
If high DA would reduce resistance and drag as some have indicated, and it certainly makes sense to me that it would, well then I can see how running the car at a high altitude would certainly not have hurt its time, and possibly could have helped. How much, I wouldn't even hazard a quess.
And like you, I also doubt MT imposed a penalty on the car for running in what would have been advantageous conditions,... at least for it.
At any rate, I love a good mystery too.
And the sleuth in me, is pointing farther and farther away from an explanation and conclusion of "ringers" and other shenanigans.
I do agree that we need to stop discussing about how Motor Trend/ Car and Driver got their number months ago, at least NOT in this thread. There is no way to prove what specs they had anyway at this point. Wild or educated speculations are not helping this thread. All of these discussion are just "side show".
That's why we need to measure the performance ourselves now, so we can verify the 10.9 second 1/4 mile independently. Most of us just want to know what a 510 kw P90DL can do in a drag strip. So far, just a lot of talking and no one is doing it. We need time slip and independent/reliable data.
Thanks! Please enter it at GridSpace's spreadsheet. We are trying to collect more data.
Tesla Model S P85/90D(L) Comparisons (Responses)
Not unless he has the login and password for the account that Tesla is attached to.
You have the most powerful Tesla in the world right now at 512kw. Next step, bring it to a drag strip, then show us the time slip
Most powerful known to be sold to the public. Most powerful Teslas are actually the P100D mules running around.
Thanks! According to your spreadsheet, looks like the battery serial number better start with "1088" in order to get 510 kw.
Hopefully someone in California can make a suggestion since I am not familiar with the area. Show us the time slip

So here's my thoughts:
I think Tesla has been grappling with how to release improvements to their cars at a faster pace than the "model year" system while minimizing the anger of customers who "just missed out" on a new feature. That may be what we're seeing here.
Suppose Tesla is silently releasing 100 kWh batteries software-limited to 90 kWh. At the Gigafactory opening, they might announce that anyone who has a car manufactured after some date can be software-upgraded to 100 kWh. This would:
1. Be cool--software upgradeable cars (which they're really already doing on the lower-end models) and with autopilot.
2. Add more publicity value to the Gigafactory opening and help highlight Tesla's lead in the EV range space.
3. Help minimize the disappointment of owners who "just missed out". Sure, there will still be people who just missed out on the silent upgrade to 100 kWh packs, but more time will have passed and there would probably be less moaning about it if more time had passed.
Plus, I'd bet there's a much higher uptake rate of people who would upgrade from 90 to 100 kWh than from 60-70kWh--if you drive a 90, you're likely to have more money and be more interested in performance upgrades.

I was expecting a D-like announcement in which everybody finds out that "you can now order a P100D!" at the Gigafactory opening.
But in my opinion the evidence is now pointing toward a software upgrade being announced to unleash an additional 10 kWh for cars built after some date that has already passed. At least, that's a reasonable explanation for some cars now putting out much more power than their predecessors (further making me feel bad about my lowly P85).
