Why does the downforce of the mass-produced Xiaomi SU7 Ultra have less downforce than the Xiaomi SU7 Ultra prototype?
The downforce of the mass-produced Xiaomi SU7 Ultra is 285kg, which is at the level of super sports cars among mass-produced vehicles priced between 2-3 million yuan.
The Xiaomi SU7 Ultra prototype was designed for extreme track scenarios like the Nürburgring Nordschleife, without needing to consider road regulations or practicality. Therefore, it could adopt extreme aerodynamic designs as much as possible, including extremely low ground clearance, oversized front splitters/rear wings/rear diffusers, etc., achieving a maximum downforce of an astonishing 2145kg.
Due to restrictions from road regulations, the length/width of the front splitter, width/height/area of the rear wing, etc., of the mass-produced Xiaomi SU7 Ultra are significantly reduced compared to the Xiaomi SU7 Ultra prototype. Additionally, considering energy consumption needs for daily driving and the requirement for low-drag styling design, the ground clearance, approach angle, and departure angle of the Xiaomi SU7 Ultra are kept as consistent as possible with the Xiaomi SU7. Ultimately, the vehicle's range can reach 630km.
