The Aporia · Elon Musk says Tesla has a rare-earth-free motor. Should China be worried?

Elon Musk has announced that Tesla's new Cybercab motor is free of rare earth materials. According to David Zhang, a general secretary of the Shanghai-based International Intelligent Vehicle Engineering Association, this move may not be as significant as it seems, as the efficiency and performance of the motor are still uncertain compared to conventional motors containing rare earths. Zhang notes that Tesla initially developed rare-earth-free AC induction motors before switching back to using rare earth permanent-magnet motors in production with the Model 3 in 2017. The move is seen by some as a strategic effort by Tesla to strengthen its supply chain security, rather than a complete shift away from rare earths.

Story summary

Elon Musk claims that Tesla's new Cybercab motor is rare-earth-free, but experts are skeptical about its significance. According to David Zhang, general secretary of the International Intelligent Vehicle Engineering Association, this move is only a small step towards reducing industry reliance on rare earths, and it's still unclear whether the new motor can match the efficiency and performance of conventional motors that use these elements. Tesla had previously used rare-earth-free AC induction motors in some vehicles, but switched to rare earth permanent-magnet motors for mass production with the Model 3 in 2017, which offered improved performance. Musk's claim is seen as an effort by Tesla to strengthen its supply chain security and reduce reliance on China, which dominates global supplies of rare earths.
