I’m not so sure about this.It's not "cheaper to build" if it's already being built. Remanufacturing S and X would be net additional cost over existing production. That's lost money.
And always you have to ask yourself: would it sell more cars? Clearly Tesla does. That's why they didn't add large casting to Highland. Nice-to-have but a poor business decision for an existing model. Franz (I think) said this explicitly on the Sandy video.
Using 48V lowers mass and wiring harnesses. It lowers assembly complexity, making the assembly line more automatable. Some parts such as a steering column/rack and pinion go away.
48V will eventually be used on all Tesla vehicles. I don’t think it will cost more.
