Tesla had to do the R+D on a new alloy of aluminum to make this work. None of the carmakers do R+D on basic materials and are limited by the commercially available alloy formulas. They have been doing aluminum castings but they are much smaller than Tesla's.

Teslas RD budget is tiny, given for much stuff they do in-house - designing cars, autopilot, seats, batteries, robots, solar panel, solar roof, and many others. Their RD is roughly on the level of Mazda, which does much less stuff in-house. > None of the carmakers do R+D on basic materials and are limited by the commercially available alloy formulas You really believe that companies that spend billions of dollars per year on basic materials, that are some of the most important for their products, just look at the prodcut catalogue from suppliers and order from there?
- avernon 6y agoObviously Tesla is getting a much larger bang for their R+D buck. That comes from the incredible amount of talent they are able to attract vs. legacy automakers. That is pretty close to what they do. Modern car companies mostly do integration and final assembly along with some marketing and finance. Vertical integration in the American auto industry died with Henry Ford until Tesla revived it. You could argue that Toyota is somewhat vertically integrated with the cross holdings they have in some of their Japanese suppliers.
- gamblor956 6y agoObviously Tesla is getting a much larger bang for their R+D buck. Citation needed. What has Tesla been able to accomplish with its inhouse R&D that nobody else has? Other than battery design (using cells developed and manufactured by Panasonic), pretty much everything Tesla does is subpar compared to automobile industry standards.

Materials research has been constantly reducing car weight for decades, at the same time that safety was improved and production costs reduced. New aluminum and steels are developed every day. For example, the development of high strength steels have been driven by the automotive industry. The contribution of Tesla is merely anecdotic at this point.

Pretty much every traditional automaker spent more on R&D last year than Tesla made. Carmakers have tried unibody frames in the past, and they abandoned them pretty quickly because they're expensive to repair in the event of even minor accidents. (This is also why nobody else does shell cars like the Cybertruck anymore; because any damage to the shell can cause a structural weakness that would require the entire shell be replaced to make the car legally roadworthy.) With multi-part frames, individual parts of the frame can be made of different materials and stiffnesses based on the physics or safety requirements imposed on that part of the frame. This means that the overall frame can be both stronger and lighter. With a unibody frame, you have to use the same material through the frame, and the only way to adjust stiffness in any part is to control the amount of material used.
