Xiaomi has disclosed a new patent for fuel-level display technology, confirming development work on vehicles equipped with fuel storage systems rather than solely on pure electric platforms. Published on December 5 by the National Intellectual Property Administration, the filing is listed under Xiaomi’s fuel-based and hybrid technical reserves. It highlights ongoing work on software methods to stabilise driver-visible fuel readings, according to IT-home.
The patent outlines a method that first determines an initial fuel level display value inside the vehicle’s tank. The system then compares this value with a collected sensor reading. When the difference exceeds a preset threshold, the method performs at least two successive adjustments to the displayed value. These adjustments continue until the difference between the displayed level and the collected value falls below the threshold. The document states that the process reduces abrupt variations in displayed fuel level readings.
The filing specifies that the method applies to vehicles with fuel storage, placing it within Xiaomi’s hybrid or extended-range technology stream rather than its pure-electric lineup. The document does not specify which models will adopt the system. It describes a software-based approach to addressing fluctuations caused by driving behaviour, fuel movement within the tank, or temporary sensor deviations.
Xiaomi has also published several other patents related to vehicle control and battery materials development. Recent filings include control functions, drift control systems, and methods for preparing lithium iron phosphate material. These documents do not specify model allocation and cover electronics, chassis control, and battery-related processes.
Information from Chinese automotive media shows that Xiaomi is preparing three upcoming vehicles. The large, extended-range SUV, referred to as the YU9, is a three-row model exceeding 5200 mm in length and is equipped with lidar and rear-wheel steering. A revised SU7 is expected to receive hardware and software updates, with a possible extended-wheelbase version to expand rear-compartment space. Media also describe the YU7 GT as a performance version of the YU7, with output estimates exceeding 1000 horsepower from a dual-motor configuration.
In November 2025, Xiaomi delivered 46,249 new-energy vehicles, while the YU7 model recorded wholesale sales of 33,729 units. These figures follow October’s deliveries of 48,654 units, with YU7 wholesale at 33,662 units. Cumulatively, since April 3, 2024, Xiaomi has delivered over 500,000 vehicles, and 2025 deliveries have already surpassed the company’s annual target of 350,000 units.
