Please point me to where Tesla claim the P85D is a track car?
So what? The i8 isn't being promoted as a "track car" either. Volkswagen doesn't promote the Golf Station Wagon as a "track car" - and that one was also faster than the Model S.
Top Gear doesn't bother if cars are claimed to be "track cars", they just take some fast cars and put them on a track.
It's really quite cute. The whole forum is full of posts "Model S racing x y, z" - all drag races. Strangely no one protests that this isn't what the Tesla is made for. Yet have someone dare to race the Tesla outside of its core discipline and people start to sulk.
I wish there was a way for us to motivate this within Tesla as owners. Frankly, I don't care if it's a Tesla internal effort or a partnership with a 3rd party -- but with Tesla's blessing and assistance as needed.I'd imagine Tesla could make the Model S track capable someday with better cooling. It's just not something they are focused on right now

I get the impression, though, from multiple sources in and near Tesla that it's, shall we say, "significantly frowned upon" to even mention engaging the track enthusiast crowd and evaluating improvements in that regard. I find this shortsighted and disappointing.
I'm not sure it is. Well, more specifically I'm not sure "performance after the first 5 minutes" is on their radar for at least the next decade.I disagree....Tesla, Elon, and friends repeatedly allude to "Supercar acceleration." Performance is clearly part of the DNA and spirit of the company. ...
Is this before or after they announce "P1xxD with Plaid"?next major overhaul of Model S
I wonder if the new Inconel contactor / smart fuse would help in the sustained performance of Model S. I assume lots of track driving would be at, or near, max power draw, and if the fuse and/or contactor was a limiting factor in discharge it might help.

Would this offer the same kind of torque? If not, a dual motor setup could compensate to maintain a similar torque curve.While there's a serious dearth of information available to the public about exactly why the car is pulling power, the best explanations I've heard suggest it is driving motor rotor heating - or possibly even predicted drive motor rotor heating - that is causing the response.
It's not easy to cool the rotor of an electric motor. Tesla apparently uses a hollow shaft and pumps coolant through it. From some european documents, it's been suggested that the continuous rating on the P85 might only be ~70 kW (though it'll let you have 300+ kW for acceleration.)
Siemens apparently came up with some innovative solutions here for their prototype aircraft electric motor, which might be suitable for future Tesla efforts. They claim to be able to sustain 260 kW from a 50 kg (110 pound) electric motor at 2500 rpm.
That kind of continuous rating could make a trackable Tesla practical, if approach they used is otherwise suitable - and the lower RPM would mean less gearing needed.

I wonder if then it might be worthwhile, for not only sustained performance reasons but longevity reasons as well, to get these upgrades on a non P85d model S. While it might not come into play in 0-60 times for the non-P models, perhaps it would offer sustained levels of power at the respective model's respective performance level.

Yes, I'm talking about the "sustained performance" problem.
As an example, would Intel make much money selling a CPU that can run 4x as fast in the first 5 minutes than it can for the rest of the hour? Probably not. And they definitely wouldn't call it a "performance" CPU.
