It isn't a matter of 4680 being good or not Tesla made a decision of not doing a double layer pack, that would easily achieved a 500+ miles of range, but since the shrunk all the dimensions, that would either eat into interior space, or ruin the proportions by making it too tall for the length...

Not really, now we need to speculate on the pack layout lol 1366 is almost certain wrong, because there isn't a round divisor that get the overall voltage close to 800 V Maybe the 48 V system also uses a few 4680s, haven't run the numbers yet to try to find the most likely configuration

One the the reviews says it's at most 1.8 mm

Yes, but if I remember correctly, they use a bunch of stand alone contactors to make it happen, more expensive and bulkier, Tesla designed a single tiny switch that integrates all that

Simulations done on a non Tesla engineering 3D model are useless, small features can have a tremendous effect on drag coefficient, no one that did those CFD analysis have an accurate 3D model

Well, the only source for that I have is the earnings call, which Drew said more than once that they planned and were on track to ramp 4680 production well ahead of Cybertruck ramp I can't find the exact quotes, but if you look at the transcripts of this year earnings call you will find it

For now, because they didn't have enough when they started it's pilot run, Semi is the vehicle that most benefit from it and almost certainty will use when they enter series production They are making a 4680 factory in Nevada, where Semi will be built in high volumes Right now there is...

The thing is, we have a bit of information that tells us that 4680 production is about to grow rapidly, faster than Cybertruck ramp Tesla spent all this time on just one 4680 line in Texas, ironing the kinks, now they go to a point that they are confident enough that they are ramping line 2...

4680 Model Y was made with V1 cells, 86.5 Wh and 828 cells for a 71.6 kWh pack Second gen cells are 95 Wh, so the pack with the same config is 78.6 kWh. Currently 2170 packs are 82 kWh for US Model Y, 78 kWh for CN and EU Model 3/Y Run rate is at around 5 GWh/y, which is 144k cells a day...

Most info we have seen points out that Austin never made V1 cells

They scrapped Model Y 4680 because all the cells that went into it were made at Kato Rd in California, they took the production line down there and are outfitting it to produce gen 3 4680s Secondly, if Tesla just put the 4680 V2s (aka Cybercells) on the 4680 Model Y, it would be quite close to...

Yep, Tesla has a likely excess of cells for the start of the ramp, and 4680 is ramping fast now, to the point that soon they will need to find places to put them, because not the Model Y, Cybertruck and Semi combined will be able to absorb the 300 GWh they have ramping and in development On...

You have to add the IRA credit, US government pays Tesla $45/kWh of 4680 manufactured and assembled into a pack For 123 kWh, even being pessimistic and assuming 120 $/kWh, the true cost for Tesla is 75 $/kWh, or $9225 for the cells in the pack If we assume the 500 miles version will be around...

The stainless panels weight in at around 300 kg at 3 mm, each drive unit is around 100 kg, and using the best energy density of Tesla pack so far, 180 Wh/kg, a 135 kWh pack would be 750 kg and a 170 kWh 944 kg Overall 1250 to 1444 kg, or in 'Merica units 2755 to 3183 lbs, leaving almost the...

It's +50 kWh added, not how much is left, without knowing the SoC it started we can't learn anything from it

A big difference is suspension Rivian isn't at the max height, F150 is on springs, but Cybertruck looks like it was jacked up, which on air suspensions usually means it's quite rigid, so any bump the wheels can't articulate as well, meaning it will have less weight and slip This is important...

Yep It should at least be on par with R1T Dual Motor, which is rated at 363 Wh/mi, Tesla likely can beat that, so a 170 to 180 kWh pack can hit 500 miles, maybe even smaller If you upscale a Model X efficiency for the weight and size we have, you arrive at 367 Wh/km, but that was with the...

That is completely wrong, it always takes the charging curve into account and also the current conditions of the battery Doing the math as above taking 77 kW and assuming it considers it will keep at that power for the remaining 55 minutes is also wrong The numbers on the side bar doesn't make...

Awesome work Your dimensions line up with what I came up with also, but mine were a bit more conservative with more margin from the pack to the exterior 148 kWh in a single layer of just cells touching each other and considering the 4680s V1, which now would be 163 kWh My estimates for pack...

Wait, what is your source they aren't putting out a 500 mile one? A bunch of source less leaks we had in the past months? While we have the Tesla sourced 500 mile version from the unveil and nothing from then indicates they changed But yeah, lets wait
