Cybercab motor achieves range without rare earth metals

Tesla's Cybercab motor has been engineered to operate without rare earth metals while maintaining the same range as comparable designs, Elon Musk announced on X. "This was extremely hard to achieve," Musk wrote, underscoring the technical challenge involved.

Rare earth elements have long been a constraint in electric motor design, particularly for high-performance applications. Their extraction and processing carry environmental and geopolitical complications, making alternatives strategically valuable. Tesla's success in designing a motor that delivers equivalent range without them could streamline supply chains and reduce production dependencies.

Details on the motor's specific architecture, efficiency metrics, or how it compares to Cybercab competitors remain limited. The development aligns with Tesla's broader push toward the Cybercab robotaxi, which is ramping up public rides and expanding to international markets this month.
