Long-term Episode 78 · Question 1

In the documentary of Xiaomi SU7 Ultra's first attempt at the Nürburgring, why did it appear that there was a power interruption (no power)? What was the actual situation?

Official answer

Thank you for your attention to Xiaomi SU7 Ultra's Nürburgring challenge and for watching our documentary.

Our backend detected a loss of signal from the speed sensor around the 4-minute 17-second mark. After completing the lap time test, we inspected the vehicle and found no abnormalities in the powertrain.

Due to weather conditions on the day of the test, there were many fallen leaves on the track surface. We determined that the leaves had blocked the speed sensor, causing the traction control system to actively reduce torque. This was not a power interruption. Regarding this newly discovered operating condition, our engineering team has analyzed it and identified solutions and plans.

Track challenges always involve uncertainties. Normally, multiple laps would be attempted in a single day to achieve better results. Unfortunately, due to limited testing time this round, only one lap could be completed. We hope for better weather conditions and a longer time window next time to achieve an even better Nürburgring lap time.
