The Yancheng Proving Ground is the largest automotive proving ground in Asia and one of the most advanced automotive test tracks in the world. Covering over 10,000 mu, it boasts more than 110 kilometers of professional test roads, capable of meeting full-scenario testing needs such as high-speed, handling, and simulated rain and fog. Choosing this location for the live broadcast is mainly based on three points: First, the road types are comprehensive enough. The proving ground features 25 charac…

This was our first live broadcast test. Considering the changeable weather in Yancheng, we initially estimated it would take 7 hours. However, the actual testing process went much more smoothly and took less time than anticipated. The entire event concluded successfully in just five and a half hours. During the live broadcast, we also received many comments and interactions from netizens. We have carefully collected everyone's comments and suggestions, and we thank you all again for your support…

This live broadcast, held at the CATARC Yancheng Automotive Proving Ground, lasted a total of five and a half hours. It featured two models, the YU7 Standard Edition and the YU7 GT, and completed eight major categories of professional tests and working condition demonstrations: high-speed oval top speed test, continuous emergency braking test, chassis comprehensive road condition test, driving and handling capability test, extrication capability test, NVH (quietness) test, reinforced durability …

Top speed performance is fundamentally a reflection of the comprehensive technical strength of the vehicle's chassis, battery, electric drive, and thermal management systems. It also means the vehicle possesses higher safety and performance redundancy. Although the extreme performance of the three-electric system may not be used during daily commuting, the hardware and tuning that support high top speeds are at work everywhere in daily driving. The high-speed oval test was conducted on the T7 hi…

Remaining stable after 50 consecutive emergency braking stops relies on the outstanding braking performance and anti-heat fade capability provided by the YU7 GT's powerful carbon-ceramic braking system. During this live broadcast, the driver accelerated the YU7 GT on the T2 straight-line performance road to a speed of approximately 105 km/h as shown on the VBOX test instrument, braked with full force to a stop, made a U-turn, and repeated this cycle for 50 consecutive sets. The average braking d…

The name "Belgian block road" comes from the cobblestone roads commonly found in Europe, where there are gaps and height differences between the stones. The wheels are continuously pushed up and dropped irregularly, generating high-frequency impacts, which specifically tests the chassis's vibration filtering capability. The Belgian block road simulates the worst daily road conditions—speed bumps, potholes, and unpaved roads. It tests the suspension's ability to filter continuous bumps as the veh…

Choosing to test on a race track is to verify the vehicle's stability in various extreme environments and refine its cornering performance. This achieves a driving feel that is "solid, premium, and fast yet stable in corners," allowing every driver to enjoy the thrill of driving on long trips and feel more at ease in daily driving scenarios. This test utilized two professional test surfaces: the T10 dry handling road and the T12 wet handling road. The T10 meets FIA F4 standards and is used to te…

In real-world daily driving scenarios, we encounter not only smooth paved roads but also situations like rainy or snowy days, wet and slippery ramps, starting on muddy roads, and wheel slip or suspension caused by uneven terrain. All of these severely test the vehicle's power distribution and recovery capability. The recovery capability test brings these complex road conditions into the proving ground to verify whether the vehicle can reduce wheel spin, pass through smoothly, and complete the re…

Laboratory NVH testing relies on equipment to simulate operating conditions, which differs from the actual driving environment. The road conditions at the Yancheng proving ground are much more complex. Therefore, we specifically arranged operating condition demonstrations during this livestream to intuitively recreate the real scenarios of NVH testing at the Yancheng proving ground. The livestream used a dedicated professional NVH road featuring three typical asphalt surfaces: large-particle asp…

The proving ground roads are "deliberately designed" to create extreme operating conditions. When testing on the reinforced road, the vehicle continuously endures extreme vibration and impact far beyond daily driving. Research data shows that when a vehicle passes over a corrugated road at a specified speed, the vertical force amplitude on a single wheel can reach up to 6806N. Under these physical conditions, significant noise inside the car is an inevitable physical process. The roads at the pr…

This test primarily verifies the AEB safety assist system's ability to recognize irregularly shaped obstacles. Low obstacles like cardboard boxes are harder to identify than conventional targets like vehicles and pedestrians, placing higher demands on the system's recognition capabilities. Xiaomi AEB's ability to recognize targets continues to expand. In addition to common targets like vehicles, pedestrians, and two-wheelers, it can recognize common obstacles such as water-filled barriers and cr…
