The Xiaomi SU7 Ultra is designed for high-performance driving as Xiaomi’s high-performance flagship EV. It combines exceptional performance with cutting-edge technology to deliver an extraordinary driving experience. It is perfect for both daily driving and hitting the track.
Xiaomi SU7 Ultra has the same tri-motor configuration and track-optimized battery pack as the Xiaomi SU7 Ultra Prototype (prototype car), delivering a maximum horsepower of 1548PS. With 0-100km/h acceleration in only 1.98s (without one-foot rollout) and a designed maximum speed of 350km/h, it is built to be the fastest four-door mass-produced car. Xiaomi SU7 Ultra features a track-optimized cooling system, ensuring it can complete two laps on the Nürburgring Nordschleife without overheating.
It is also equipped with a top-level braking system, achieving a braking distance of only 30.8m from 100km/h to 0. Xiaomi SU7 Ultra also has a peak chassis system tuned for the Nürburgring Nordschleife, delivering better chassis control and a higher control ceiling. As a four-door “race car”, it is track-ready straight from the factory. In addition, the Xiaomi SU7 Ultra offers multiple upgrades in smart driving, smart cockpit, safety, and luxury experience.
On October 28, the Xiaomi SU7 Ultra Prototype completed its first Nürburgring Nordschleife lap challenge, breaking the seven-year record for the fastest four-door sedan with a time of 6’46″874 — making the first time a Chinese brand has claimed the title of “The Nürburgring Nordschleife World’s Fastest Four-Door Car.” Xiaomi EV will keep exploring breakthrough innovations in pure electric technology and validating its cars through the Nürburgring Nordschleife testing. The mass-produced version of Xiaomi SU7 Ultra will also challenge the Nürburgring Nordschleife next year.
Born for high-performance: From street to track, where beauty meets function
The design of Xiaomi SU7 Ultra prioritizes peak performance, with each new design element serving functional purposes, free from unnecessary decoration. For exterior design, the Xiaomi SU7 Ultra builds on the Xiaomi SU7 Max with an added aerodynamic kit and larger body dimensions. At 5115mm length, 1970mm width, 1465mm height, and 3000mm wheelbase, the body is longer and lower and presents a more aggressive, battle-ready stance.
The front of the Xiaomi SU7 Ultra features an oversized front splitter and air dam, along with U-shaped air curtains to effectively increase the downforce of the front of the car. The enlarged air intake grille opening increases the heat dissipation area by 10%. An active rear diffuser has been added, with two-speed adaptive adjustment, balancing wind resistance and downforce, and energy efficiency for daily driving. Additionally, a new carbon fiber fixed rear spoiler (1560mm wingspan, 240mm chord length) delivers considerable downforce at high speeds. Thanks to the new aerodynamic design, the Xiaomi SU7 Ultra achieves a maximum downforce of 285kg, comparable to that of a supercar.
The interior of the Xiaomi SU7 Ultra emphasizes sportiness through upgraded seats and steering wheel design. The new sports seats feature enhanced active side support with faster response speed and a larger support area, providing better body control during intense driving. The seats showcase exclusive track embroidery stripes and the Ultra embroidered logo, adding to the sporty aesthetic.
The steering wheel of Xiaomi SU7 features a completely new design, adopting a race-designed flat top and bottom. The material has been upgraded to carbon fiber. The grip is covered with Alcantara®️ microfiber fabric, which is not easy to slip. A yellow centering marker at 12 o’clock aids the steering wheel during intense handling. The new design, coupled with the yellow seat belts and the red Boost button on the steering wheel, creates a race-ready cockpit atmosphere in the interior of the Xiaomi SU7 Ultra.
The interior materials of Xiaomi SU7 Ultra are also further enhanced, with Italian Alcantara®️ microfiber fabric extensively used throughout the car, covering over 5m². The material wraps the full seat contact surfaces, steering wheel grip areas, dashboard stitching, and interior door panels, delivering a premium feel and a more immersive driving environment.
The Xiaomi SU7 Ultra extensively uses carbon fiber materials, enhancing sportiness and reducing weight. Interior carbon fiber elements include the front-seat back panels, center console panel, and door sill plates, reinforcing the athletic aesthetic. For exterior design, Xiaomi SU7 Ultra features a 1.7m² large carbon fiber roof, reducing weight by 12kg. Carbon fiber appears in 17 locations, totaling 3.74m². 90% of these components are manufactured using a premium hot press process, ensuring superior texture and quality.
