Figures depend on version and test conditions. Read the article and linked primary sources before comparing models.
Xiaomi SU7 Ultra is the tri-motor performance flagship of the SU7 family. Its official specifications combine 1,548 PS with a quoted 1.98-second 0-100 km/h time, a designed 350 km/h maximum speed, and a 630 km CLTC range.
Its track story includes both a production vehicle with Track Package and a separate SU7 Ultra Prototype. Their lap times belong to different vehicle categories and should never be presented as though the production road car achieved the prototype result.

- The official production-car Nordschleife time is 7:04.957 with Track Package.
- The SU7 Ultra Prototype recorded 6:46.874 in 2024 and 6:22.091 in 2025.

Production-car performance specifications
The production SU7 Ultra has a tri-motor all-wheel-drive system using two Xiaomi HyperEngine V8s motors and one V6s. Xiaomi quotes 1,548 PS, 0-100 km/h in 1.98 seconds without one-foot rollout, 0-200 km/h in 5.86 seconds, and a designed top speed of 350 km/h.
The official acceleration footnote specifies the relevant high-performance tire setup. Results outside controlled conditions will vary with tire, temperature, charge level, surface, vehicle configuration, and driver procedure.
Battery, charging, and braking
The CATL Qilin 2.0 track-oriented battery is rated for a maximum 1,330 kW discharge output and up to 5.2C charging. Xiaomi quotes an 11-minute 10-80% charge and 630 km CLTC range.
Xiaomi's launch material quotes 30.8 m from 100 km/h to zero and describes carbon-ceramic brake discs with high-performance calipers and pads. These are manufacturer test results, not a guarantee for every road surface or tire condition.
The 7:04.957 production-car lap
On April 1, 2025, driver Vincent Radermecker completed an officially measured 20.8 km Nordschleife lap in 7:04.957 in an SU7 Ultra with Track Package. The Nurburgring classified it in the electric executive-car category and it set a category record at that time.
The circuit's current record table should be used for present-day rankings because later vehicles can supersede an earlier record. The 7:04.957 time remains the official recorded SU7 Ultra production-car result.
Prototype results are a separate story
The dedicated SU7 Ultra Prototype first recorded 6:46.874 on October 28, 2024. It returned on April 1, 2025 and improved to 6:22.091. The official Nurburgring table lists those runs in the prototype or pre-series category.
The prototype used a much more extreme track-focused package and should not be treated as a production-road-car specification. Responsible comparisons must state which vehicle, category, package, driver, date, and lap length produced the time.
