100D or 105D speculation

[ucmndd]

I drove the battery down to 20% then charged on L2 to 90%, recording the data given below using teslafi.
Charging capacity = 68.76 kWh/(249.59 mi/369 mi) = 101.7 kWh.

I don’t find this particular partial charging test to be anywhere near rigorous or scientific enough to support your claims that there was a quiet chemistry change that resulted in an unpublished capacity increase.

There are way too many variables that make this a dubious claim at best.

Agreed. Based on just one charging session? Come on... I wouldn't even call it a dubious claim. I'd call it pure speculation.

I have a 100 pack from mid-2020 in my personal S. Its usable capacity is 97 kWh, well inside the range of known 100 packs. A vehicle I recently saw from 2021 has the same pack part number. Seems unlikely they would change chemistry but keep the part number.

The refresh has a brand new battery chemistry for sure but I don't think it's rolled out to the current cars.

here is a reference supporting chemistry change across the fleet, model 3 physical pack size increased to 82 kWh.

I have done more than just one charging test, all in 100-101 kWh range, I'll dig up the data and share.

You can also read this thread for more info on the new -h pack.

2021 Model X, Monroney Sticker Range Increase

So my basic question: is battery larger than 100Kwh? Its hard for me to believe you get from 296 to 371mi range just by efficiencies alone

Here is more charging capacity data, the charge capacity decreases as the battery wears and range drops, as you can see below.
