Xiaomi SU7 Ultra Prototype's performance at the Nürburgring Nordschleife demonstrates Xiaomi's world-class technology system, engineering capabilities, depth of R&D expertise, and talent strength. These track-proven capabilities will gradually be applied to production models.
Nürburgring Nordschleife Lap Record for Production car of Electric Executive Vehicle
*On April 1, 2025, we used the optional Professional Track Package + Carbon fiber dual-vent front hood + Aerodynamic underbody plate to break the Nürburgring Nordschleife lap record for a production electric vehicle, becoming the fastest production EV in Nürburgring history. SU7 Ultra, with Nürburgring-certified safety modifications, once again takes on the Nordschleife.
