On October 5, Tesla's official X account released a 9-second teaser video, trailer (can be translated as foreshadowing here, but kept as is in the final output for accuracy to original if no perfect English equivalent is needed in context, though a proper translation would omit Chinese) foreshadowing a major announcement on October 7. The video only shows a high-speed rotating metal turbine-like component with the Tesla Logo embedded in the center, concluding with a date marker '10/7', sparking speculation.
