Sandy would not need to do a teardown since IRDA is already going to do a teardown so they can ship the gigapress to Austin.Sandy said specifically he was invited to IDRA. I don't think they'll let him do a gigapress teardown, tho
Literally this pack - with seats and console - is lighter than the square pack-as-cargo from the original Model S.I think the most interesting thing about this video (and it is all pretty interesting) is what they said about the weight of the pack being something like 1000 lbs less then many of the competitor packs they are looking at. It sounds like the weight advantage of the 4680 + structural pack design might be huge.
Based on this, the pack itself may not be lighter then an equivalent Model Y pack. He says in other thread that there might not be a net weight savings, but there should be cost savings.MunroLiveStuart
To clarify, those heavier batteries were the Plaid and Rivian. Rivian alone is nearly 800kg. Our 2020 Model Y was 440kg.
Personally, I don't think that the seats, center console, and carpet are 100kg, so the battery pack itself is probably heavier than the old design. The big savings is in eliminating the load floor, both in terms of weight, raw material cost, and labor cost. Just being able to stand inside the vehicle and install the pillar trim rather than hang into the vehicle from outside, bend backward, and clip it in is a huge ergonomic advantage.
Tesla is playing the big picture game, seeking gains across the entire vehicle, rather than looking at single part savings.
I think the big save is being able to get rid of the load floor in the body in white. It might not be a weight save at all in the end, but it's definitely a cost save at piece cost level, and a systemic level by eliminating part numbers, warranty claims and scrap due to those part numbers, etc.
One of my larger concerns as a mechanical engineering with a background in industrial engineering, and just being an ethical person, is always ergonomics. Being able to get inside the body and STAND UP to install the interior trim with a pushing motion, rather than crawl around in the body over pokey studs and brackets, or lean in door openings to install stuff with a pulling motion, makes a huge difference in workplace safety and stress injuries.
At the 8 minute mark Corey says Sandy is in Italy.
Anyone think he's doing something gigapress related?
This alleviates a big fear I had with CT battery being so heavy that efficiency numbers would not be reasonable. IMO weight is a BFD.I think the most interesting thing about this video (and it is all pretty interesting) is what they said about the weight of the pack being something like 1000 lbs less then many of the competitor packs they are looking at.

1.) I can't wait for the actual pack density numbers. If Tesla is sandbagging on the range for now we could see really good numbers here. Note the seats and carpet don't weigh much. While this may have manufacturing benefits the current apparent pack density is not that impressive.
The likelihood that tesla won't have LFP structural solved before Texas ramps to 1 million is extremely low. LFP structural will probably be sorted by end of Q4 this year at worst.Texas Tesla
China Texas is shipping NMC tooling to Texas Tesla so it can build Model Y with old NMC. Once Texas Tesla gets the NMC tooling, production will increase up to 1 Million Model Y per year.
Will Texas Tesla ever go back to the structural LFP battery pack if production is ramped up to 1 Million Model Y with old NMC tooling?
Texas Tesla if it can't fix its structural LFP battery pack production problems with the Model Y, how is that going to affect the EvTruck structural LFP battery pack that has no NMC tooling?
The cost savings of LFP and lack of cobalt are huge incentives for them to get this solved. They are already building 1/2 of their production with LFP, so clearly they are committed to the chemistry. I can see why you might be concerned, but I'm giving Tesla the benefit of the doubt that they will get it solved.
