In the 2024 annual speech, Lei Jun reviewed the story of building a car for three years. In the One more thing section, he said that his goal is to become the top 5 car factories in the world in 10 to 15 years. This requires Xiaomi Auto to confront the world’s top car companies on the world’s peak track, that is, the North Ring Road in New Bogeling.
Conquering New Bogeling North Ring Circuit and becoming the fastest four-door tram is the mission of Xiaomi SU7 Ultra prototype released today. Let’s take a look at this ultimate performance machine.
In terms of space, the three-dimensional length, width and height are 5260mm, 2064mm and 1406mm, respectively, and the wheelbase is 3000mm, which is 300mm longer, 101mm wider and 34mm shorter than Xiaomi SU7 in size, making it shorter and wider.
In terms of power, the combination of three motors, two V8s+one V6s is used, with a total power of 1548ps, which exceeds the super-running, bringing 0-100km/h acceleration of 1.97s (including the start time), 0-200km/h acceleration of 5.96s, 0-300km/h acceleration of 15.07s, and the top speed of 350km/h.
In order to meet the long-term high-power output of the track, Contemporary Amperex Technology Co., Limited Kirin 2nd generation battery pack dedicated for the track is used, with a charging rate of 5.2c, a maximum discharge power of 1330kW and a discharge power of 800kW when the battery is 20% low.
Braking performance is also at the track level. The maximum deceleration of kinetic energy recovery is 0.6g, which is more than 2.36g in the extreme speed state, and the stopping distance of 100% braking is 25m, with the special brake calipers, brake discs and brake pads for the track.
In order to become the fastest four-door tram in New North, Xiaomi SU7 Ultra pursues extreme lightweight and uses a full carbon design. Front lip, bumper, fender, side skirt, side wall, rear bumper, diffuser, tail wing, roof, front and rear machine covers, 24 parts in total, achieving a vehicle weight of 1.9 tons, which is lower than the current 1.96 tons.
A large number of aerodynamic components not only make the car look sharp and domineering, but also are just the opposite of the ordinary electric car’s low wind resistance to optimize the battery life. The aerodynamic components of the track machine can provide the car with a maximum downforce of 2145kg, which exceeds the weight of the car. Theoretically, it can run backwards on the ceiling at extreme speed.
Lei Jun said that the impact on New North is divided into two steps. First, the prototype will be used to pick the non-production lap list in early October and challenge the production lap list in 2025. "The challenge is the dream of our millet. There is a big gap between us and Porsche, but it doesn’t matter. As long as we start to catch up, we are on the way to winning. "
