On September 19th, Xiaomi Automobile made a significant announcement, revealing the rollout of a substantial OTA (Over-the-Air) autumn update. This update will see both the Xiaomi SU7 and YU7 models receive an upgrade to the Xiaomi HyperOS 1.10.0 system simultaneously, ensuring that both vehicle models stay at the forefront of technological advancements and user experience enhancements. (Here, "unveils" is a more vivid and commonly used verb in the context of product updates, and "revealing the rollout" makes the sentence flow more naturally in English. The additional phrase "ensuring that..." provides a clearer context for the significance of the update.)
