... if it meant that there'd be no reason to put an asterisk on it and call it out... so no, it does not mean that.
And actual 0-60s as measured by others for those vehicles confirm those are with rollout times-- Further discussion on it and more detail about it here:
Even Porsche uses 1 ft rollout in the US. Basically everyone does.
Sure there would be. Otherwise one can argue that the time between hitting the pedal and the car actually moving (which is small, but measurable) would count.
The fact that the magazines (which do subtract rollout) tend to beat Chevy’s claimed 0-60s also suggests that Chevy isn’t subtracting rollout.
You were correct Car and Driver and Motortrend subtracted it, but Porsche didn't on their website. I just saw an article about the GT3 with a 2.7 0-60 and it said in there that it was from a rolling start and that all tests are.
Yeah if anything Porsche is notorious for underselling their numbers. They claim 3.2 for the GT3’s 0-60, while car and driver beat that by a lot (even when you add the 0.2s 1ft back into the time). Similarly they claim a much lower range value than you get in the real world for the Taycan
If we take the 2023 MP motors: 3D3/3D6 = 158+255kw = 553hp --> 455hp and then apply that to the sleuthed 2024 MP motors: 3D3/5D1 = 158+314kw = 633hp --> 520hp. That's what I'm expecting as a minimum HP bump. It's a good chance they'll do better but I don't think anyone should be surprised if we see ~520hp.
The issue is that the HP ratings are just simply not true. Tesla just makes up numbers that they tell the governments for those documents.
They told the EPA that the Model 3 Performance only has 321 KW of power which is 435 HP. That is just laughable for a ~4,050 lb car doing 11.4 second 1/4 mile times with only a single fixed gear ratio.
They list only 312 KW for the Model Y Performance. There is no way the Model Y Performance makes less power than the Model 3 Performance. That just simply can’t be true.
People should stop caring about “max HP” for an electric car. It is totally irrelevant for EVs that can only hold max HP for a couple of mph.
Honestly, we shouldn’t really even care about measuring HP at all for EVs. Just tell me the 0-60 mph and 1/4 mile time with trap speed. That tells me WAY more about the car’s acceleration than telling me a max HP number at an unknown rpm or vehicle speed.

A "foot" isn't really a thing in Europe unless it's attached to your lower leg, and cars don't have legs like horses.
Ironically we think “football” is a game where you throw a ball to the other players for almost the entire game. You are trying to avoid kicking the ball as much as possible in what we refer to as “football”.A "foot" isn't really a thing in Europe unless it's attached to your lower leg, and cars don't have legs like horses.

You could probably get pretty close from logging the peak kW output of the battery. Convert that to HP minus a bit for wiring loss.

Includes CANBUS data captured by WUGZ some time ago for all configs of the 3 including the various SW updates that added power
Given how the HP varies with SOC and temperature, it's probably the case their rating is under specific conditions that are different from hp numbers achieved under more optimal circumstances. I see it as being conservatively rated vs. outright fabrication of data. With that said, my ass-umption is their ratings are under consistent circumstances for each motor so a %difference rating from one motor to the next is representative of actual performance differences.
Elon didn't lie if you actually listen to what he said instead of creating your own strawman to knock down. Elon said that the carbon overwrap allows the motor to spin faster that it would without a carbon overwrap. At no point does he make a comparison of Model 3 and Model S motor speeds. Also, he specifically does mention, more than once, how the carbon overwrap enables a smaller rotor stator gap.
Also, here are a couple of Elon's tweets at the time.
“Fiber is wound over rotor at high tension load. Machine to do this was made by Tesla Automation.Carbon sleeve must put copper rotor in compression or it loosens at low temp due to differential thermal expansion. Preload is also helpful for maintaining precise gap to stator.”
“Main advantage of this is a much stronger EM field compared with a rotor that is held together by metal (usually high strength steel). Other advantage is that rotor can go to higher RPM, as carbon sleeve (mostly) stops copper rotor from expanding due to radial acceleration.”

That's all it takes? I've an ultra-bridge I'd like to talk to you about...Yeah my wife has a red Y. Ultra red is so good it made me test drive the Plaid but yep it’s still a boat. Also I’m an ultra runner so it’s a must.
You also cannot pronounce Aluminium but we love you all anyway, quirks and all
