Video Summary
A speed test of the Xiaomi SU7 Max on a track resulted in a collision with a tire wall, deploying the airbags and activating the SOS system. The individual involved, Tang Zhu Liao Che, stated that there were warning signs indicating brake failure before the collision. An automotive blogger, Director Xiong, warned against track use of the Xiaomi SU7, reporting accidents involving other SU7s during testing.The friction material of the MAX version brake pads disintegrated rapidly, and the wear of original brake pads was an issue. In some vehicles, there were complaints of oil stains on the lower wishbone and bare motors at the back.
The Xiaomi SU7's braking system utilizes NAO friction pads for daily driving and has limited breaking ability to endure consecutive pushing for 2 laps on the track.
Promotional materials emphasized racing feel and performance, but tests revealed significant discrepancies with data, with an actual test range of 643km compared to a claimed 810km. The acceleration time does not meet official specifications; it was 3.24 seconds instead of 2.78 seconds. Adaptive cruise control was limited to 120km/h rather than the advertised 135km/h.
Some owners reported a non-deploying airbag in a front-end crash and others noted issues such as being unable to remove charging plugs from Tesla stations, battery malfunctions, soft plastic bumpers, and the car's tendency to be sent to a tow truck soon after purchase. The infotainment system also suffers from malfunctioning GPS navigation. The insurance premiums for Xiaomi SU7s are comparable to those of more expensive gasoline vehicles, a claim which is supported by the fact that that EV accident rates are reportedly much higher than gas cars in China. A comparison was made between Porsche Taycans and Xiaomi SU7 designs.
