In the week before September 6, 2026, Tesla announced the launch of a new rare-earth-free motor during the Cybercab event. This motor has a 18% smaller size, 25% less weight, and significantly improved power density and efficiency. It has been applied to the current small-batch-operated Cybercab models. This move aims to reduce dependence on the rare-earth supply chain, which is highly concentrated in China, while optimizing vehicle space layout and system energy efficiency. Musk later confirmed on social media that the technology was real, but he did not disclose the specific alternative materials. Currently, this motor has not been installed in other mass-produced models, and its prospects for large-scale application remain to be seen.
