I do wonder about the Ioniq EV figure and whether the EPA has done their own verification (own testing) of Hyundai's numbers. Or, if they screwed up and will need to downgrade it (ala https://hyundaimpginfo.com/aboutsettlement in the past).

And should get even a little better once we get a dual motor version. What kind of efficiency gains did we see in the Model S going from single motor to dual motor?


In real world it is not significant but the S had a smaller motor in the front on the non-P and I doubt that will be the case with the PM motors, likely the same motor front and back with software for separating performance versions.

IMO, a few weeks will eventually be probably extended just a bit forward...to forever.

Tesla cuts Model 3 part orders to Taiwan supplier Hota: report

TAIPEI (Reuters) - Luxury electric carmaker Tesla (TSLA.O) plans to slash by 40 percent its orders for parts for the new Model 3 mass-market sedan from Taiwanese auto component maker Hota Industrial Mfg. Co (1536.TW) from December, according to a media report.

Shares of the parts maker dropped nearly 9 percent after the Economic Daily News reported, citing Hota Chairman Shen Kuo-jung, that Tesla had told the firm orders would be cut to 3,000 sets per week from 5,000 sets starting December, due to a “bottleneck” in the production of Model 3.

Tesla may delay scheduled weekly shipments of 10,000 parts in March by a few weeks until May or June, the report added...

In the world of "Just In Time" Manufacturing this isn't such a big deal. Simply confirms what we already know. Tesla is behind on production. Which is what everyone assumed and predicted. Not sure why everyone is freaking out. Of bigger concern is that Tesla hasn't figured out how to go from concept to production as quickly as other automakers. Maybe once they start making some money off of the Model 3 and start producing other models on the same platform they'll be a little quicker to respond to customer desires.

This negative news pales in comparison to the positive China news earlier this week. That has the potential to be a gamechanger. It all hinges on the Model 3 though. If they don't sell 500,000 cars a year for a few years they are screwed.

I'm not sure we can even say this. Other automakers would have had a longer R&D, prototype, beta, and pre-build and prime the supply chains period. Tesla definitely skipped some of those steps so they could meet a date tweeted by Elon Musk.

For sure it's fair to say that this period of releasing cars only to Tesla & SpaceX employees constitutes a pre-production time. That, however, should take nothing away from the fact that within a few months Tesla is likely to make more Model 3's than the rest of the industry makes EVs combined.

Nice prototype, but the many unfinished features and fact that TSLA doesn't even trust its own employees with autopilot (~51 minutes in) yet says a lot about how much development is probably left to do before production begins.

The new AP system is a ground up design because of new hardware. It is running on the newer model S vehicles so I don't think that is a major concern.

Thanks for posting. This was a very detailed vid.
I only skipped through but my general impression is the 3 is very solid. I had a similar impression of the Bolt when I drove it but my main takeaway was it was not enough car for the $. I think the 3 overcomes that issue. I'm not so hot on the user interface based on what I've seen. It seems to cry out for some level of voice recognition (mirror adjustment for example).
Looking forward to configuring. Still hoping it's this year. My only reference point is an employee who configured his Model 3 back in early August and still no VIN or precise delivery date. So, that's a 6 week slip right there. Our LEAF turns 7 next month and it's about used up.
The wait for that car also took forever and far fewer were in line. First world problems.

Really? And where are the numbers for the Model S with that change? Probably significant (10-15% - based on comment), right?
That single S induction motor was really that inefficient (NOT)?

Remember, the Model 3 uses a PM which gained a little efficiency over the Model S with an induction motor.

Totally "a ground up design", absolutely no resources, e.g. the basic AP AI algorithms, pulled from the Mobileye design, right? You know this
as fact, as you're a Tesla AP system consultant or Tesla AP team member, or maybe you just know some of the production line installers?

It is very public that they are doing it in house now. They need to do all new software for the new hardware platform and there is a new team hired in charge which is irrelevant to the point. Anytime a company can leverage resources they do of course, Do you think they just leveraged the old software and were incompetent in uploading it or tweaking it even though they are competent in everything they have done in shorter time periods then any other car company . Then there is Nissan that has been in the business for years and has had the LEAF out longer than any other EV and they have the worst half-baked tech on the market, they are crippled by their culture and management. Oh, and yes I know the person that was hired to do this, and it's a secret conspiracy to defraud the public...... The first part is true. What does a line installer have to do with software development exactly?

Right, that's basically a re-compile of the original source code to run on the Nvidia processor, and NOT a total redesign.

Good, so you now agree it's not "a ground up design".

Sounds like you don't understand much about software development.

At least the Nissan Leaf achieved its design goals, notwithstanding the battery, which can't said for Tesla with AP1 or AP2.

Yes, we can all make claims!
