been following this thread for a while. thanks for all the people running their independent "tests." whether they are scientifically accurate or not, it's entertaining nonetheless and keeps the conversation going.

0-60 times are almost always identical from 100% SoC to the lower numbers around +/- 30%, as long as the battery temps and all other things are identical as well. It's once you get above 60mph, when the lower SoC causes significant slow down.Hey guys, just a follow up. The Draggy came in early on my lunch. Car was charged to 55% and i did 5 runs just to see how to work the Draggy. It was harder than i thought to find a straight/level road that i wouldn't break the speed limit too bad haha. Anyways, i did 5 runs with the fastest posted here. The fastest was at 50% SoC. How does this fair at this SoC compared to others? The battery to my understanding was not that warm as it had been sitting in 50-degree weather for a while. Thoughts? I will start my testing on Wednesday...
I believe this was before the performance bump but should give you an idea.Hey guys, just a follow up. The Draggy came in early on my lunch.

Thanks, I've seen this video! I wonder if anything has changed since then besides the obvious power increase. "Cold weather improvements" are a little vague.I believe this was before the performance bump but should give you an idea.

At what mph do you start to see bigger acceleration time differences at different SoC?0-60 times are almost always identical from 100% SoC to the lower numbers around +/- 30%, as long as the battery temps and all other things are identical as well. It's once you get above 60mph, when the lower SoC causes significant slow down.
Usually starts falling on its face right after 60mph, by 100mph, it feels like a honda. At least the older battery packs did, I am waiting until it warms back up before doing anything with the '21.At what mph do you start to see bigger acceleration time differences at different SoC?
my 2021 feels like a Honda Insight at 100 mph now that you mentioned it.Usually starts falling on its face right after 60mph, by 100mph, it feels like a honda. At least the older battery packs did, I am waiting until it warms back up before doing anything with the '21.

from the first experience (U-Haul) to now, how much would you say it has improved? Last summer, i went down to San Diego and spent a couple days there where the temperature was sitting around 100. My car felt the fastest it ever had, currently living in Santa Barbara and my new car feels slower. I assume due to the cold weather though.My '21P becomes quite noticeably slower below ~93% and dramatically slower below 80%. Maybe I'm watching the gauge too closely but I swear I can even feel a difference between 99% and 100%.
When it was new it performed like a U-Haul van below 20% and honestly couldn't even keep up with freeway traffic with the pedal held to the floor but the software update a few months ago vastly improved that to typical minivan levels.
So in my experience it seems that every single percent of SOC is significant - from forklift performance at 1% to supercar performance at 100%
Think any modifications to power delivery could change this in the future with our current cars?Usually starts falling on its face right after 60mph, by 100mph, it feels like a honda. At least the older battery packs did, I am waiting until it warms back up before doing anything with the '21.
I wonder if this will be the trend for improved EV performance or if it is more economical to implement a 2-speed transmission in performance applications.Lack of a lot of pull up top is mainly a result of a 1-speed transmission and a ~13k redline of the motors.
Model S Plaid solved this but keeping the 1-speed, but using advanced tech to let the motors spin to 20k so it still pulls like a freight train WELL north of 100 mph.
2 speed tranny is a crutch.I wonder if this will be the trend for improved EV performance or if it is more economical to implement a 2-speed transmission in performance applications.
Can you explain this a bit more and your sources?Lack of a lot of pull up top is mainly a result of a 1-speed transmission and a ~13k redline of the motors.

To be clear, only a few of the very first roadsters (~30) had a two speed, and it was locked into 2nd gear, giving quite slow performance. They quickly moved to a one speed. This pretty famously delayed the program for a year or two.Remember the original roadster had a 2-speed, something Tesla has not repeated since. Porsche has, and it still pales in performance compared to the Plaid.
You kinda did The very definition of controlling an AC motor is a variable frequency drive. All Teslas have to be able to control current and frequency, and not in quantized steps. You need to be able to go from 1372Hz to 1373 Hz as the car speeds up.But someone with an electrical engineering background would be best to explain that because I'm absolutely certain I don't understand everything and probably butchered this explanation.
