The idea is to cast much larger pieces than before. Traditionally it might have been dozens of pieces. Tesla is currently doing the underbody in only three pieces, and they were trying to cast it as a single piece.

Does that warrant a new word? I don’t know. But there is an innovation here in how it is manufactured.

It's my understanding this a way to cut manufacturing costs. One wonders what impact it has on repair costs, though. Tesla isn't going to replace the entire underbody whether it's a single piece or three pieces, are they? So how easy are these pieces to repair?
