Cybercab's entire outer body is plastic: Tesla's RIM process cuts emissions 35%

Teslaconomics highlights that the Cybercab is the first production Tesla with an all-plastic outer body, with color molded directly into panels via reaction injection molding instead of a paint shop — turning a multi-hour painting process into minutes. Tesla says this cuts manufacturing emissions for those parts by 35% and eliminates paint VOCs. On safety, the plastic exterior isn't the crash structure; the large front and rear giga castings handle that. MatthewChang quotes the thread, noting there's one stainless-steel Cybercab in the world fitted with booster and car seats.
