"Paired with the new more efficient drivetrain design, Model S and Model X are now capable of achieving 200 kW on V3 Superchargers"

Not sure how this has anything to do with the new drivetrain, because last month they already announced "[a V3 supercharger] supports peak rates of up to 250kW per car" (presumably without the new drivetrain as it had not been announced yet - https://www.tesla.com/blog/introducing-v3-supercharging)

Also why did Tesla claimed 250 kW in the blog post last month, but now lowered their figure to 200 kW ? I'm so confused.

Edit: found some answers: "Model 3s will be able to take full advantage of the new Supercharger capacity [250 kW] thanks to the car’s newer battery chemistry". So the Model 3 can charge at up to 250 kW, while Model S and X are currently limited to 200 kW. Source: https://www.theverge.com/2019/3/6/18253618/tesla-supercharge...

Given the huge amount of truth stretching in the autonomy anouncment yesterday anyone here with relevant battery experience want to weigh in on this? Yesterday completely burned through some of the goodwill and trust I had for Tesla to the point that I am sceptical of anything they announce now. Is this real?

read the motortrend article. they test drove on today and said the range they got was actually about 400 miles.

The room was there to improve. Nothing about this is particularly implausible.

Paired with, not as a result of.

The lower charge speed of 200 vs 250 is likely cell limited compared to the 2170 cells in the 3.

From the text you cited, my understanding is that 200kW is already possible and they might be able to achieve up to 250kW using that approach.

Earlier quoted context omitted.

I'd bet that the TPMS (tire pressure monitor/sensor) in the wheels is an off the shelf component purchased from a top-10 supplier in the automotive industry, and the problem was as simple as not having the TPMS programmed for the car. This is the same problem you can encounter if you replace all four TPMS in most any medium to high end car manufactured after about 2006, and the tire shop forgets to use their handheld…

Your local Walmart auto care center will reset/relearn the TPMS system for free, and the tool they use does support Tesla.

Teslas have a button on the menus in the console for that kind of reset... must have been more than just a different vin.

This "continuous deployment" for cars must be a logistical nightmare. To do repairs for a given vehicle, keeping track of what parts are backward compatible would be challenging. What if it's a compatibility breaking change? Then keeping inventory for older cars would become problematic. Unless they do design with maximum compatibility. Then it gets interesting as upgrades are possible. While B.EV cars maintenance is…

They have very few moving parts. I am guessing they are switching battery pack modules out so it's not that hard. Theres battery packs, motos and basically thats it.

> Model S and Model X are now capable of achieving 200 kW on V3 Superchargers and 145 kW on V2 Superchargers. Together, these improvements enable our customers to recharge their miles 50% faster. What does that mean exactly? I'm sure there are sections of the charge curve where it is 50% faster, but you need to consider the entire charge curve to get a better sense of the improvement. The Tesla Model 3's charge times…

Interestingly, the charge rate across the entire curve sounds like an important metric but in practice it is nearly irrelevant. If you drive an ICE car, you are used to filling your tank. Because once you've gone through the trouble of driving to a gas station and pulling out your credit card and unscrewing the cap, well you might as well top it off, right? Life is different with electric. You might know, for example…

None of these justifications answer the question I've asked. Read the link I've provided. The Tesla Model 3 can get to 90% state of charge in 40 minutes in ideal conditions. How many minutes will it now take the Model S and Model X to do the same?

The amount of time spent at a charger to get decent range matters. Read this article for an example of someone who likes his Tesla Model 3 but is getting frustrated with the amount of time he's spending at chargers:

Slight tangent but what are you getting for $20K? Is it a software feature, or is there physical difference between the normal performance and "Ludicrous" model?

There is a smart fuse composed of an inconel alloy that is pyro-actuated to protect from overcurrent conditions when performing a Ludicrous launch (~1500 amp peak current drawn). It's not software only. Very fancy circuit breaker.

I am 80% sure this is a line from NCIS.
