What will be the new HP numbers for AWD and P after 12.4?

Then you have invented new physics and should rewrite every book that I have read. I develop high-performance PM motors at work so I know some of this stuff...

a graph from Mclaren. The point where torque starts to drop and peak power is reached is called base speed.

Also: Tesla Model 3 SR+ Dyno Testing You can clearly see the constant torque area and power increasing until torque starts to drop. That's why cars have gearboxes. Power is just a product of torque x rpm. You need torque to accelerate.

Good read for beginners: Motor Control 101

Patronizing somebody after you misconstrued their comment just digs the hole deeper

There's some really good Dyno testing on the motors but it does not reflect the latest software update, only the earlier ones with some modest power bump. I have that file somewhere maybe when I get to where I'm going I'll post it.

That would be awesome - thank you!

@ch_model_s What you are saying is obviously true (I also understand how electric motors work). I'm not certain, however, that when Tesla says "power" they actually mean just "peak power." The last "5% power boost" resulted in more torque [measured as acceleration] across the entire power band. It's entirely possible that THIS time they actually mean JUST power [e.g. above the base speed] or they could be conflating acceleration performance [torque] with power again. Many people (wrongly...) think "more powerful = better acceleration under all circumstances." I think we'll just have to wait and see when the update is actually released widely.

My accelerometer data from the last boost:

I don't doubt that you know what you are talking about, but the battery/supply also has a influence on the output.

So in the above graph, you may be assuming an unlimited supply KW to the motor, but in reality, the KW supplied to the motor may well be capped below what the motor could produce - might be current or voltage limited. (Definitely, since P3D produces more that the others, with the same motor, and almost certainly ALL are capped for longevity reasons, Also, what do the motor in the S Performance produce?)

Would this have the effect of sifting this graph to the left, so that then the continuous power line would peak earlier/lower, and the drop off continues down.

So this looks like the right shape, but needs to be shifted to the left by 50%, so the base speed occurs at about 5K

The LR AWD graph would then 'artificially', flatten out both power and torque curves 15% lower.

Yes I'm pretty sure you can just look up online what kilowatts translates into in terms of horsepower....

Hi Siri how many HP is 400kW?
Siri: That would be 548.85HP

For what it's worth, there are horsepower calculators available. Do a little research, find out the vehicle weight, then find out the best known quarter-mile time for your exact model, enter the figures and hit "calculate."

What charge would be "intelligent and fair"? It would have to be at least the difference between the cost of the two versions without the performance package (at a minimum), and ideally, to keep people who actually purchased the P version off the bat, would need to be a little more than that delta to "reward" the people who purchased the P first from the factory vs upgrade.

Most threads on this topic of upgrading devolve into people thinking they should be able to purchase the upgrade for "a couple thousand" because "its just software".

It would have to be more than the delta between an AWD and Stealth P, just like adding FSD after delivery is more. You don't want to encourage people to buy the down trim version by letting them upgrade for the same price later.

Of course that delta has been as small as $2000 recently

Also they removed the "it costs more after purchase" thing from FSD.

I wish there were better numbers available for all the variants. I generally use the wikapedia numbers. They did update these after the last bump, and hopefully will after this next one. View attachment 470180

My SR+ was 3576lb

Surely someone has access to a dyno and can do a before/after before the next update? I'd love to see the two graphs overlayed. I'm confident that when Elon says 5% power increase, he isn't talking peak HP but rather 5% through the curve. Not that one is ultimately better than the other but I can see how optimizing the frequencies could result in an improved powerband but I'm less optimistic that optimizing the inventer can produce 5% more peak power.

We will do it. The last time there was a 5% increase, we didn't see it on the dyno.

You are doing God's work my friend!

This must be why diesel cars are so much quicker than their gas counterparts...

You, sir, clearly do not have redneck friends/family with tuned up diesel trucks...

Here you go! I think this was after the first of two power bumps. But not sure - could have been after the second one. You can see power for the RWD LR, the AWD and the Performance AWD. Both HP and torque.

I'm assuming both green and yellow are RWD? Does it seem odd that the RWD put out 205 HP?

I believe they are the AWD, and Performance running in Chill mode, i.e. They both produce the same torque/hp then.

Given the second one hasn't gone into general release yet that seems unlikely

Is the above graph HP/Tq #'s to the wheels? If so, comparable engine HP/Tq would be like 50-100 higher(assuming 15-20% loss)
