He is providing misleading information. The only verified info I could hear was the 3kwH increase. This will most probably be updated to ’21 models as well.
All of the other ”2022 upgrades” info was a combination of differences in GT model and normal software & other updates which happen continuously not per model year.
As was discussed when this was originally posted a month ago, @AoA missed the mark on this. His entire premise was based on thinking the GT he had was a 2022, when it was actually a 2021. The improvements he mentions are just updates in the latest software, not new for 2022.
