Rumor: Tesla’s new rare-earth-free Cybercab motor claims technical improvements

Unconfirmed: Tesla showcased at its Cybercab event a new rare-earth-free electric motor reportedly 18% smaller, 25% lighter, and more efficient than other high-performance motors. This motor avoids elements like neodymium and dysprosium used in permanent magnets, potentially reducing reliance on critical materials. Tesla had announced in 2023 its plan to develop permanent magnet motors without rare earths, possibly using iron ferrite or aluminum-nickel-cobalt alloys. However, there is no official confirmation or full technical details about the Cybercab motor’s design or production.

• Rare-earth-free motor is 18% smaller than other motors
• Rare-earth-free motor is 25% lighter and more efficient
