On December 25, 2025, Xiaomi Automobile officially launched the Xiaomi HyperOS 1.11 winter major version OTA update, covering all SU7 and YU7 models. This upgrade focuses on "enhanced safety and a smarter cockpit," introducing several active safety features and immersive interactive experiences for the first time, marking a crucial step for Xiaomi Automobile in the field of intelligent driving and human-vehicle interaction.
The biggest highlight of this OTA update is the systematic expansion of active safety capabilities, achieving full-scenario coverage from high speed to low speed, and from forward to backward:
Emergency Steering Assist (AES): At high speeds of 80–135 km/h, when the system determines that the risk of a frontal collision cannot be effectively avoided by AEB, if lane and space conditions permit, the vehicle will automatically perform emergency steering to avoid the collision, significantly improving the ability to handle sudden risks at high speeds. This function is only supported on SU7 Pro, Max, Ultra, and YU7 models.
Low-Speed Collision Avoidance Assist (LAEB/RAEB): Adds dual-mode low-speed collision avoidance for forward (1–10 km/h) and backward (1–30 km/h) driving, capable of identifying static and dynamic obstacles such as vehicles, pedestrians, two-wheeled vehicles, walls, pillars, and crash barriers. When the driver does not intervene in time, the system will actively warn and brake, significantly improving safety in high-frequency scenarios such as parking and maneuvering in congested traffic.
MAI + AEB Joint Protection: All models support the collaborative work of "Misacceleration Inhibition Assist (MAI)" and "AEB," effectively reducing the risk of collisions caused by the driver accidentally pressing the accelerator, providing double protection, especially when parking in narrow spaces.
This safety function upgrade expands Xiaomi Automobile's collision avoidance assist working speed range from the previous 5–135 km/h to a comprehensive forward 1–135 km/h and backward 1–30 km/h, achieving industry-leading full-speed active safety coverage.
Voice Interaction: From Passive Response to Proactive Service
"One-Sentence Creation of Xiaomi Super Tasks": Users can create personalized tasks through natural voice commands, such as "When there's no one in the back seat, please turn off the rear air conditioning." The system will automatically recognize the context and execute the command, achieving true "semantic understanding + scenario linkage."
Upgraded "Super Xiaoai Proactive Intelligence": Based on vehicle usage behavior and internal and external environments (such as temperature, humidity, weather, and battery level), the system proactively pushes thoughtful suggestions, for example:
Reminding to activate "Slippery Mode" in inclement weather;
Suggesting activating AUTO mode when air conditioning efficiency is low;
Prompting to activate "Temperature Zone Synchronization" when the temperature difference between the driver and passenger is too large.
Entertainment System: Immersive In-Cabin Karaoke and Sound Revolution
Microphone-Free Karaoke Function: Supports five major audio sources: QQ Music, NetEase Cloud Music, Kugou Music, Bluetooth music, and USB music. No external microphone is needed; all passengers can participate in an immersive karaoke experience. Six professional microphone sound effects are built-in, making "everyone a lead singer."
AI Multi-Channel Immersive Sound Effects: All audio applications now feature AI audio rendering technology, reconstructing the sound field spatial sense and providing a cinematic listening experience, significantly improving sound quality layering and immersion, especially during high-speed cruising.
Navigation and Charging: Maps that Understand You Better, Charging with More Ease
Map Visual Upgrade: Added high-precision rendering elements such as trees and buildings, making the urban environment more realistic and intuitive; "food, drink, and entertainment" locations support large-model one-sentence summaries of features and prices, significantly improving decision-making efficiency.
Cruise Traffic Light Display: Even when not navigating, the car screen can still display a real-time countdown of upcoming traffic lights, reducing sudden braking and anxiety at intersections.
Charging Map Optimization: Added tags such as "Super Charging," "Preferred," and "Free Parking," making charging station brands and availability clear at a glance. It supports intelligent charging path planning, improving efficiency for long-distance travel.
In HyperOS 1.11, Xiaomi HAD Enhanced (SU7 Pro/Max only) introduces reinforcement learning algorithms and a world model, achieving a leap in three core capabilities:
|
Capability Dimension |
Before optimization |
After optimization |
|
Longitudinal control |
When following another car, acceleration and deceleration are rather abrupt. |
Anticipating deceleration in advance allows for smoother acceleration while following other vehicles, closely resembling the rhythm of human driving. |
|
Lateral control |
Hesitation when changing lanes, reliance on manual confirmation |
Lane changes, merging, and detours are now more decisive and smoother, reducing any sense of lag. |
|
Road condition understanding |
Dependency navigation instructions |
It can "understand" navigation intent at complex multi-lane intersections and automatically select the optimal lane. |
This upgrade transforms the HAD system from "assisted execution" to "active decision-making," laying the algorithmic foundation for future advanced autonomous driving.

Xiaomi SU7 series |
✅ Fully rolled out |
Starting December 25, 2025, all SU7 owners can access the vehicle's infotainment system or through XiaomiAutomobile. App receives updates |
|
Xiaomi YU7 series |
⏳ Pushing out in batches |
Due to occasional issues discovered during the initial limited rollout, Xiaomi is optimizing the rollout and rolling it out in batches to ensure a better user experience. Full coverage is expected within 1-2 weeks. |
Limited user feedback so far: Currently, there is no large amount of real-world user experience data; system stability and long-term experience still require time for verification.
Clear functional permission layering: Advanced features such as AES and HAD Enhanced are only available on Pro and higher models. Standard version users experience a significant difference in safety and intelligent features, leading to discussions among some users about "feature limitations."
Large OTA update package size: The official size has not been announced, but it involves underlying system, AI model, and map data updates, and is expected to be over 10GB. Users are advised to complete the upgrade in a Wi-Fi environment.
