    Toyota has been saying a few years from now

    Toyota is full of shit regarding EV, they are not competitive at all on EV, so they try to make people not by an EV now, but wait until the next car. Toyota has wasted their research on Hydrogen, and that’s going nowhere fast, that’s a point where Musk was right already 10-15 years ago. But that was before he got weird.

    I read the article from the link you provided, apparently VW plans to build 40 million cars on the new “platform”, so Tesla making 20 million will not make them surpass VW and Toyota.

    Apparently VW can already make a car in 14 hours, so not that far from the 10 claimed by Tesla, and apparently there are downsides to using the big body parts Tesla uses, in for instance a car is more expensive to repair, and therefore also more easily totalled. AFAIK the machines Tesla use to press those big parts are from Italy, and I bet they tried to sell it to other car makers too.

    Regarding the 48V, I would still claim it’s a non issue, you could easily go to 48V, and then use voltage regulators to correct locally if necessary. Voltage regulators are dirt cheap today, and are probably already used in most places inside the electronics. So in most cases it’s merely a matter of using another regulator, at about zero cost.

      Got a huge laugh from me lol. Well said.

      The 30 vs 10 was specifically for EVs. They haven’t figured it out yet on their electric vehicles.

      A lot of people say what you have about the castings having problems on repairs, but what actually happens is if the accident is big enough to reach the casting, the car is totaled anyway castings or not. They have replaceable crush bars for smaller accidents. It’s not as big a problem as people think. Everyone is going to switch to castings to stay competitive, and some already have.

      you could easily go to 48V,

      You might think that, but legacy has been talking about it for decades now, and hasn’t. One of Tesla’s leads in the video I linked shows a circuit board which handles many things, and on it, they talk about stepping down to 24v for the audio amplifiers which are on the same board, which they also want to make 48v in the next iteration. The thing is, those are custom in house designed circuit boards. Legacy outsources most of that stuff, they aren’t as vertically integrated on the power electronics and can’t just do that easily.

      That’s why it’s a chicken and egg problem for them with their suppliers.

      Edit: oops, and ya, we’ll see if VW can do 40 mil, but the 10x part doesn’t need to include that, even VW then would be worth way more. We’re looking at what things are worth today and projecting out.

      Edit: just to clarify the above edit, if Tesla does make 20 mil vehicles with high margins, even if VW makes 40 mil with high or low margins, Tesla would still be worth a lot, and VW would be worth more as well with the variability being are they high or low margin. The valuation will come from the revenue and profits and future growth outlook.
