This could explain why the Model 3 Highland isn't using front/rear castings - could it be getting a single casting?
Haha, no! Tesla is working on possible ways to cast the underbody of the forthcoming Model 2/Robotaxi at Giga Texas as we speak. They have not settled on an approach yet, as always they are experimenting with multiple technologies and will choose the best one. This was covered here last wee as the 'sand die-casting' discusion, along with a potential 16K ton Gigapress.

The innovation is rapid, low-cost production of prototype dies for the gigapress: think "weeks vs. years" to get a new candidate die into testing, and $30K for each prototype vs. $1M (keep in mind they may need to go through half a dozen prototypes before reaching a production-ready design). The ability to make their own dies for the gigapress is a huge win for Tesla, that's why they're spending the effort on R&D to create this tech.
So this won't happen in Shanghai, or for the Model 3 / Highland, or on the timeline you suggest. It'll happen in Austin in time for Model 2/Robotaxi, then in Monterrey, MX then go wide... Of course, roto-REUTERS drops the soap.
Cheers to the Longs!
