Xiaomi Auto announced today that its SU7 Ultra prototype reached a 6:46.874 lap time at Nürburgring Nordschleife, making it the world’s fastest four-door car on the track.

Completing the Nürburgring challenge wasn’t easy for Xiaomi Auto. The company booked the track for January 9 and October 10. However, on October 9, it rained all day, and on October 10, there were multiple sudden showers.

On October 17 Nürburgring officials coordinated another try for Xiaomi, but it failed again due to heavy rain. On October 21, Xiaomi borrowed time between charted venues, but it failed again for unspecified reasons.

Finally, on October 24, Nürburgring officials managed a 1-hour window between 11:00 – 12:00 on 28th October.

Track surveying finished at 11:30 a.m. when tires were loaded, and debugging was carried out. At 11:50 a.m., Xiaomi SU7 took off and crossed the finish line at 11:56:46.874 a.m. In the evening, at 7:50 p.m., Nürburgring officials confirmed the lap time of Xiaomi SU7, Xiaomi says.

Xiaomi Auto will unveil the production model of the SU7 Ultra later today. “Its debut marks not only an outstanding feat but also the start of an exciting new chapter,” commented the company’s founder and CEO, Lei Jun.

The SU7 Ultra prototype was first announced during Lei Jun’s annual address in July. He described it as a track-ready, high-performance version of the SU7 sedan.

Xiaomi launched the all-electric SU7, its first car, on March 28. It offers three versions: the Standard, Pro, and Max, with starting prices ranging from RMB 215,900 yuan (30,200 USD ) to RMB 299,900 yuan (42,000 USD). The SU7 Ultra production version is expected to cost about 800,000 yuan (112,000 USD)

Equipped with Xiaomi’s V8s motor, which generates 1138 kW (1526 hp) at a peak speed of 27,200 rpm, the SU7 Ultra prototype demonstrates serious speed. It reaches 100 km/h in just 1.97 seconds and 200 km/h in under six seconds, with a top speed exceeding 350 km/h. The curb weight is supposed to be 1,900 kg.

David Pittard, who recently won the 2023 24 Hours of the Nürburgring, was behind the wheel. At its event today, Xiaomi will reveal more about the SU7 Ultra’s production version, which is set to launch in the first half of 2025.

According to Lei, the production model will retain the prototype’s core structure, triple-motor setup, and battery configuration. It is important to note that the Nürburgring time of SU7 belongs to the prototype, not the mass production version.
