Highlights.

• Tesla is closing in on an innovation that would allow it to die cast nearly all the complex underbody of an EV in one piece, rather than about 400 parts in a conventional car
• Sources said Tesla's previously unreported new design and manufacturing techniques meant the company could develop a car from the ground up in 18 to 24 months, while most rivals can currently take anywhere from three to four years
• To cast subframes with hollows as part of one gigacasting, Tesla plans to place solid sand cores printed by the binder jets within the overall mold. Once the part has been cast, the sand is removed to leave the voids
