It is reported that after the launch of Xiaomi SU7, many users drove it on the racetrack. In June of this year, a blogger released a video of a Xiaomi SU7 accident on the racetrack, claiming that the SU7 had a tail speed of up to 214km/h, lost its brakes, and forcefully swung into the pendulum, ultimately resulting in a racetrack accident. On July 21st, a Xiaomi SU7 internal training vehicle ran off the track and crashed into the buffer zone during daily testing at the Jingang racetrack. All of these have raised concerns among users about the braking ability of the Xiaomi SU7, and there has been a widespread discourse on the internet that "Xiaomi cannot stop braking". Regarding this, Xiaomi officials stated that the SU7 is essentially designed for home use, and although it has outstanding performance, it is not suitable for long-term intense driving on the track.
According to the data, the current braking system of Xiaomi SU7 uses NAO friction pads, which are suitable for daily driving, balancing braking noise and braking performance. Track driving is completely different from daily driving. Under track conditions, the continuous high load and high temperature accelerate the wear rate of components, far exceeding the requirements of vehicles under daily conditions. The braking system used in racing is uncomfortable in daily driving, and racing brakes with higher metal oxide content will produce friction noise during braking, which brings a bad daily use experience. Different product performance focuses on configuring according to different driving needs.
In mid July, Xiaomi Auto officially released the OTA upgrade of version 1.2.3, with a highly anticipated optimization of the brake disc high temperature alarm reminder. This upgrade is obviously aimed at providing early warning to many car owners and media personnel when they encounter problems while driving SU7 on the track, in order to assist drivers in better controlling the car. Combined with the high-performance braking kit released this time, it is expected to effectively enhance the overall braking performance of Xiaomi SU7 on the racetrack.
On the evening of July 19th, Lei Jun shared the prototype of Xiaomi SU7 Ultra during his speech. This car was specifically designed to challenge Porsche and the New North Circuit in Germany, striving to become the fastest four door electric car in New North within ten years. It is based on the Xiaomi SU7 and has undergone comprehensive evolution for the track, with longer, wider, and lower seats. The length of the car reaches 5260mm and the width is 2064mm. The side is designed with wind blades and a large tail wing, full of combat atmosphere. For better track performance, the entire vehicle is made of all carbon fiber materials.
In terms of power, the Xiaomi SU7 Ultra is equipped with dual V8s+V6s three motor all wheel drive, with an astonishing output power of 1548 horsepower. It is also equipped with a track specific high-efficiency battery pack, which can continuously output ultra-high power. This racing car is also equipped with a track specific braking system, including AP brake calipers, track specific brake discs, etc. The braking distance from 100-0km/h is only 25m. At the same time, the large-sized diffuser at the rear, combined with a fixed racing tail, can provide a maximum downforce of 2145kg.
In October this year, Xiaomi Auto will officially enter the New York North region. Lei Jun also admitted that this challenge is not easy, and we may succeed or encounter setbacks, "but we will continue to challenge until we ultimately win." This persistence has infected many Xiaomi SU7 users, who are eager to personally experience the speed and passion of racing culture. The release of the Xiaomi SU7 high-performance braking kit can be seen as a positive response to user needs.
