Source report date: October 8, 2026 · Published: October 12, 2026
On October 8, 2026, fDrive.cz reported on a speed record attempt in Czechia; it did not give the exact date of the run. Racing driver Tomáš Vavřinec was at the wheel of the Xiaomi SU7 Ultra. The run took place on the main runway of Hradec Králové airport, closed for the attempt; according to the article, the stretch was about 2.5 km long and the surface had been cleaned beforehand.
What kind of record
As fDrive.cz writes, 323 km/h is a new Czech record for a "neupravený sériově vyráběný osobní automobil", meaning an unmodified series-production passenger car. The previous result was 309 km/h and, according to the outlet, had stood for more than two decades. The car kept its series specification, ran on factory Pirelli P Zero Elect tires and drove away under its own power after the attempt.
The article gives the SU7 Ultra's power (1,538 hp) and 0-100 km/h acceleration of under two seconds; these are manufacturer figures, not results of this attempt. It does not say how the speed was measured or which organization confirmed the record, and the exact date of the run is also missing. We therefore rely on a single source and call it a record only on its authority.
