See sources & confidence →The SU7 Ultra is the production version of the SU7 Ultra Prototype that ran a 6:46.874 lap of the Nürburgring Nordschleife in October 2024 — beating the Porsche Taycan Turbo GT (7:07) and putting Xiaomi on the production-EV-record map. The roadgoing Ultra retains the prototype's three-motor layout and aero, with a slightly detuned 1,548 hp combined and a softer street-legal suspension and tyre choice. Pricing was confirmed at ¥529,900 in February 2025 — significantly below the rumoured ¥800,000 figure that circulated pre-launch. Unlike the standard SU7 Max, the Ultra is a low-volume halo product. It exists to anchor the brand at the top of the performance ladder, signal Xiaomi's serious intent in EVs, and serve as a marketing lighthouse for the entire SU7 line.

How the Ultra got its lap
- 01October 2024: SU7 Ultra Prototype, with full racing aero and slick tyres, sets 6:46.874 at the Nürburgring Nordschleife — Lap timed and verified independently. This made it the fastest production-derived four-door EV ever timed at the 'Ring.
- 02February 2025: Production SU7 Ultra is unveiled at ¥529,900, undercutting initial estimates by roughly ¥250,000. The roadgoing version retains three motors and most of the prototype's aero hardware.
- 03March 2025: Customer deliveries begin; over 10,000 reservations in the first 10 minutes of order opening — closer to a Xiaomi smartphone launch than a typical car launch.
- 04May 2025: Independent test outlets log production-Ultra 0-100 km/h in 1.98 s, matching factory claim and beating Tesla Model S Plaid (~2.1 s with rollout) and Porsche Taycan Turbo GT (2.1 s).
- 05Q3 2025: First Western magazine first drives appear (limited China-only events), with hands-on praise for the powertrain and reservations about chassis tuning under sustained track abuse.
- 06Ongoing: An OTA-only 'Track Mode 2.0' update has been demoed but not released; expected to remove the 350 km/h electronic limit on closed-circuit telemetry-locked sessions.
The SU7 Ultra is the headline car of Xiaomi's EV programme — the one that made global automotive press take Xiaomi seriously. At ¥529,900 it is genuinely cheap for what it delivers: figures that compete with the Porsche Taycan Turbo GT, the Tesla Model S Plaid, and the Lucid Air Sapphire — all of which start at $150K+ in their home markets. Whether the production car holds up under repeated track abuse is the story still being written.
