Theres just was a post in a Swedish facebook forum about the EPA range for model Y’s are adjusted down in USA, this might be a correction for starting to use the LG batteries that is slightly smaller.
You mean Model 3 LR not Model Y, right? Model 3 LR was recently re-introduced in the US and range went down from 358 EPA miles to 333. Makes sense that it's due to the LG pack.
My apologies for listing my post in the wrong thread. Just noticed this thread is focused on 2021's. Moderators, feel free to move if necessary.
To answer your question, I believe it's just the battery that comes from China.
That's what I thought but just wanted to confirm because they've recently started delivering Shanghai made cars in Canada.
