"Vehicle Identification Number numbers"?

Just like PIN number, ATM machine, CAC card, and "is that a work PC or personal?" It's a very typical construction, for whatever reason.

"is that a work PC or personal?"

I disagree with putting this one into the same category. The "personal" in "PC" means "used by a single person; not shared" which is quite different from the meaning of "not belonging to an employer".

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…

I operate several websites that help people find the right part for their car or tractor. It's always a nightmare.

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 th…

Perfect example. This owner added 110 miles of range in 45 minutes, or ~26kWh, which means an average charge rate of 35kW. He charged from approximately 48% to 83%.

With V3 he could add the same range in about 15-18 minutes -- that's based on eyeballing the charge rate curve in your other link.

The S and X will see similar gains now, because this generation of technology is the same as the TM3.

I do not believe that Tesla has published an actual charge percentage vs time curve for this new S/X update, but you can rest assured the many tech blogs which cover Tesla's every move will have one posted as soon as someone can get their hands on one. There will be parts of the curve which are significantly more than 50% higher charge rates (perhaps up to 400% increases at most), and parts which are virtually unchanged (above 90% capacity).

In the meantime, you should be confident that when Tesla says "expect to charge 50% faster" that's a real average number based on actual usage data they collect in the field, and sometimes you will beat it, sometimes not, depending on many variables which can impact charge rate.

One things that won't be impacting your charge rate on V3 are the Teslas charging next to you. In the article you linked, I would speculate the 35kW average charge rate is due to shared main feeds in V1/V2 Supercharger stations.

Actually they're quoting 660km on https://www.tesla.com/en_AU/models/design#battery

That's according to the NEDC test cycle which is the most optimistic (and therefore the least useful) range estimate. The three test cycles that are typically used are: NEDC (too optimistic): https://en.wikipedia.org/wiki/New_European_Driving_Cycle WLTP (better than NEDC, still a little optimistic): https://en.wikipedia.org/wiki/Worldwide_harmonized_light_veh... EPA (the most conservative): https://en.wikipedia.org/w…

My S 75D has 384km range (not really near the EPA 417km) and it is approximately 21 % optimistic which I would not call "little".

Route planners (ABRP, previously Tesla) will not let you drive 300km without charging, because you would arrive with less than 10 % SoC.

In other words, let’s kill off people [0] from air pollution so car maintenance can be simpler. 0: http://www.prevenzione.ulss20.verona.it/docs/Sisp/Inquinamen...

I wonder how much of the additional complexity is actually necessary for lower emissions.

More to the point, how much of the complexity is an excuse to charge $4000 at the dealership for something an independent mechanic could do for $495 except that there is some kind of DMCA nonsense in the car to prevent that on purpose.

For metric folks, this equates to nearly 600km. That's about as much as I want to drive in the space of a single day. Conceivably however, automated driving could mean doing longer distances. And at a cost much less than an airfare - just a lot more in time.

And it'd be a more comfortable environment to get work done during the trip too.

I wonder if NEDC/WLTP/EPA just ignore heating and A/C entirely? That's not a big issue for ICE, but it would be for an EV.

" 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…

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.

Ah, yes.

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.

There are a lot of moving parts in the suspension, the transmission, the battery cooling system, the AC, the power windows, power steering, all the other comfort features like electric seats, electric tailgate, ...

Just because it doesn't need an oil change doesn't mean that it doesn't need service.

> Ludicrous Mode upgrade, a $20,000 value I have a P85D. When Ludicrous Mode was announced, they offered it for $5000 as an upgrade. I have no idea why it now supposedly costs $20,000. Source: https://www.teslarati.com/tesla-drops-price-of-p85d-ludicrou...

That $US20k seems to be purely marketing bullshit, aimed to sucker US buyers. :( Easy seen as such too. Compare the "Ludicrous Mode" for the Model X on the US website (US$20k) to the same thing on the Australian website (AUS$8.5k): https://www.tesla.com/modelx/design?redirect=no#battery https://www.tesla.com/en_AU/modelx/design?redirect=no#batter...

The entire feature is marketing bullshit. There is no practical utility in making a car that fast go even faster, it's sold only as weapon in the battle to express the desired length of one's phallus in vehicle form.

They should charge $15,000 for the first "10% faster" and then another $25,000 on top of that for the second 10%.
