From a real car perspective, the Xiaomi SU7 Ultra prototype car has undergone professional tuning at the track level. The rear spoiler is quite eye-catching and protrudes from the body of the car. The new car is equipped with special racing tires and the wheel arches have been optimized. The body can be seen with lightning-fast stripes and an "Ultra" logo. The front of the car and the lower part of the doors also have large spoilers, making the entire car very low-slung. It is expected that the interior will also be equipped with anti-roll bars and other facilities, and will be made as lightweight as possible.

The Xiaomi SU7 Ultra prototype car adopts a "full carbon" design, with 100% of the body coverings made from carbon fiber materials, reducing the overall weight to 1900kg. In terms of power, this prototype car is equipped with dual V8s + V6s three-motor all-wheel drive, producing an astonishing 1548 horsepower. It also comes with a dedicated racing high-efficiency battery pack that can continuously output massive power. The acceleration from 0-100km/h takes 1.97 seconds, from 0-200km/h takes 5.96 seconds, and from 0-300km/h takes 15.07 seconds, with a top speed exceeding 350km/h. This racing car is also equipped with a dedicated racing braking system, including AP's brake calipers and dedicated racing brake discs, requiring only 25 meters to stop from 100km/h.
