They may have learned a few tricks from those teardowns of BYDs.

that started with another US car manufacturer, tesla.

(although tesla had casting hiccups with the suspension components of the model x)

so what happens when something breaks? in theory this is 100 more points of failure

honest question, not sure how BYD handles this either. but BYDs are cheap enough that if you need to you get another...

I honestly think unicastings are a horrible idea. BYD for most of its flagship vehicles do not use unicasting. I think unicasting should be reserved for the cheapest of vehicles in which an accident means the vehicle is recycled rather than unsafely repaired.
