I would suggest you watch the Munro Live videos where they disassemble and analyses cars. This company has been doing this for decades and recently started making some videos. The changes in Tesla vehicles are absurdly fast. They disassembled original Model 3 and then China Model 3, and since then the refresh 3 and the Y. Recently they showed the new Model 3 LFP (Lithium Iron Phosphate) and the electronics and how it was integrated is already different again.
