Why did Xiaomi SU7 Ultra only reach a top speed of 324km/h during the sprint on the long straight at the end of the Nürburgring?
Official answer
The top speed performance of electric vehicles is influenced by comprehensive factors such as battery level and track conditions. The Nürburgring is 20.832km long in total, and the end of the track features a long straight. This section has an overall uphill trend, and on the day of the test, parts of the track surface were wet, which consumed significant vehicle performance. Under these circumstances of limited battery capacity, the Xiaomi SU7 Ultra prototype reached a top speed of 324km/h on the final straight.
