    Am I the only one that sees the irony in this?

    So I suppose you’ll have to reserve a Roadster or give up your tagline?:)

    But nobody runs 1-4 motors off multiple packs. If there is an inverter fault, it can pull 3.9x the single pack current limit, unless in addition to the 8 contactors, they add 4 pyrofuses. Which they could, but I don't see the advantage. If there is a wiring fault, all the packs must blow their fuses, unless the contactors are rated to break the max pack current x 4. That does not sound like a million mile no break down system. It sounds like a multiple source of single point failure.

    What's the worse case imbalance due to torque one could get in a single trip? How much more could one motor be used to require all packs to be in parallel? Is there a use case where a motor used 5% SOC more than the others and actually limited range?

    Don’t think it hasn’t occurred to me. But I have until 2020 (plus or plus) to figure that out.

    ..was trying to think what would require me to give up “overt”. Possibly the witless (sic) protection program?o_O

    A NASCAR track? Yeah, real world use would probably even it all out.

    Hopefully I am the first to mention this on the internet and this forum regarding the new roadster...

    Just checking my understanding - the Model 3 (and thus semi and presumably the Roadster) motors are all permanent magnet. Does that make them easier to cool? And was motor heat the limiting factor for the Model S not being to be a track car? Or was it battery heating? Regardless, I sure hope they have solved the cooling issue with the Roadster...

    The rotor on an induction motor heats up due to the induced current. I believe the Teslas have liquid cooling for it. PM motors do not have this heating effect. So less heat/ easier to cool.
    Battery cooling is then the limiting factor.

    Semi needs its own sub-forum now! :)

    I can picture it now: Kim Jong Un acquires a Semi via the gray market and uses it to haul his thermonuclear missiles around:

    What Tesla model was the Semi chasing up the hill in the Semi reveal video? Did they tease the crowd with the new Roadster before they actually showed it?

    Sure looks like it could be. Especially clear in your first screen grab. No reason they'd put random vehicles in their own video ... teasing us & we missed it!

    That would be an epic troll. Good work!

    Am I missing something … or is there really not an official recording of this event available anywhere? I've checked Tesla's website, and their Vimeo and YouTube pages, as well as the general Interwebs. I don't want to watch somebody's flattened spherical nausea-inducing footage (yes I'm picky, lol). :oops: But if there's a decent fan-filmed video out there, I'd like to see it. Recommendations?

    I'm bummed as the full version was on this page: Tesla Semi Unveil but now is gone. By full version, I mean including the actual audio and music that was played at the event. (I was there). Intro music for the Semis was "Feet Don't Fail Me Now" by Queens of the Stone Age. "Sabotage" by the Beastie Boys was used during the um, <spoiler alert>. Anyway, all the versions I'm finding online now are shorter (the original was 35 min) and/or don't have the actual event music, which gave it some energy/personality and soul.

    I downloaded the full stream, but it's 35:53 minutes and 733mb though.

    Cool. Any chance you'd be interested in posting to Youtube? :rolleyes:
