This is a nice upgrade for the Model S, however, I'm really curious what Tesla's design refresh roadmap looks like for their older models. The Model S has remained mostly the same since 2012, and while the design is pretty good, very few companies can get away without a major design refresh for 7+ years.

Do they have to follow the convention? Are consumers irked by their breaching of the convention?

I think existing owners would already understand that their cars are iteratively improved upon and that a Model S purchased in 2019 is going to be a lot better than one they purchased in 2013.

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…

Each OEM, including Tesla, maintain a database where each ever produced vehicles with all the options, including changes are recorded. Except, when they screw it up. They screw this up with PR samples and show cars, which are sometimes prepared by hand and finished up by hand just for the press or just for show. Then things get forgotten to record. Tesla had so such problems. Volkswagen had such problems and had to recall a 5 figure number, just because of this. Because PR and show cars are normally discarded after the show, after the press had it, but sometimes they get into the second hand market.

Walled garden revolution. Going to the breakers/wrecking yard for parts is akin to open source software. You are locking yourself into proprietary code, parts and pricing in this Tesla 'revolution'. A wing mirror costs $550 for example. Only authorized Tesla maintenance is permitted etc etc...

read the story of the guy with the bmw who tried to swap in a part from another one, and it wouldn't work unless the dealer programmed it to work with that new car's vehicle id. so he sold his car.

That's a common problem when trying to upgrade the iDrive head unit with one from a donor car. It can be done but requires special tools and knowledge.

In BMW's defence, they would validate the car as a system and wouldn't want to be seen to be giving implied consent for making these frankencars. Software configuration isn't like hardware; a bolt can be replaced with any bolt made by anyone as long as it is of comparable specification.

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.

Most of the complexity arises from using feedback loops in the engines similar to other control systems in industry. There are also similarities to techniques used in electronics.

What is super cool about Tesla is their laser sharp focus on creating a good electric vehicle. From the autonomy announcement and then this one, they are creating tools purpose built for cars, like new chips for self driving, battery tech etc. They have done so much in so little time, we have come to expect more from them. There is only so much a car company can innovate, Tesla has gone beyond it. Edit: I am a Tesla…

If you believe that they are doing false advertising around FSD, could they also be doing false advertising about this?

It's highly unlikely. This is a public event and they will be held even more accountable than when Elon tweets something. Lying at such a stage would risk their reputation. So I say it's unlikely, not impossible though.

I've also been in "professional" shops where the qualification is questionable, but I understand your argument. There are Tesla Certified body shops; we'll see how the workload shakes out between those facilities and Tesla Service centers. Tesla recently updated their service intervals for all vehicle models due to fleet data showing less service was required than previously indicated [1]. How many times have you see…

Many auto makers have moved their oil change intervals out to 10,000 miles when they've previously pushed 3 or 5.

In theory the oils and engines have improved to the point where 10k miles is a sound number based on evidence. However given that the only downside to more frequent oil changes is the cost of the oil change, if you plan to keep a car for a very long time, changing it more frequently than the recommendation is a reasonable plan.

Longer oil change intervals are undoubtedly fine for an engine that is expected to last at least to the end of the warranty period. Which is all the manufacturer cares about.

They're re-introducing the lower cost model, interesting move right before quarterly earnings get announced. I have to assume this means sales have been poor. > In addition to our Long Range and Performance variants, we’re also re-introducing a lower entry price for Model S and Model X by bringing back our Standard Range option

In the autonomy presentation yesterday they said they could create more robotaxis if they ship smaller batteries. So I wouldn’t assume it means sales are poor. They’re focused now on building out a self driving fleet of customer cars, which they plan to activate as taxis in the future.

> In the autonomy presentation yesterday they said they could create more robotaxis if they ship smaller batteries.

More? The challenge is not to ship more of them, the challenge is to ship one.

Question for Tesla owners: Is the recharge time ever a problem? Have you ever felt regret from not being able to just pull up to a gas station, refuel, and be on your way? Part of me drools with child-like giddiness at the prospect of owning one, but part of me hesitates at the thought of taking roadtrips in one.

Question for ICE owners: Is having to regularly visit a fuel station ever a problem? Have you ever felt regret from not being able to wake up every morning with a "full tank" in the car?

Point is, it's not a compromise, it's replacing one set of compromises with another. Yes, you are limited to driving for 4-5 hours before taking a 30-45 minute break (assuming your route has fast chargers) but that's fairly consistent with the needs of humans anyway. (Muscles, stomachs, bladders etc.)

> 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…

You're getting your numbers mixed up. It's a 33% reduction in charging time which is equal to a 50% increase in charging speed.
