BYD's Yangwang U9 Xtreme has become the first production car to exceed 500km/h, recording a single-direction top speed of 503.17km/h on a closed 10-kilometre section of road in Abu Dhabi's Al Dhafra Region on November 1, 2026. The FIA recognised the run, and it also earned two Guinness World Records: highest speed by a production car and highest speed by an electric production car, both in a single-direction run.
The record was set by German racer Marc Basseng, the same driver who took the U9 Xtreme to its previous best of 496.22km/h in 2025 on a test track in Germany. Two attempts on October 31 topped out at 490km/h before engineers adjusted the car's aerodynamics, suspension settings and tyre pressures ahead of the successful run.
How the record compares
The 503.17km/h figure extends the U9 Xtreme's margin over the Bugatti Chiron Super Sport 300+, which recorded 490.484km/h in 2019. The Bugatti remains the fastest internal combustion road car on a single-direction run, while the SSC Tuatara holds the separate two-way production-car record with a 455.3km/h average set in 2021.
Those distinctions matter because top-speed claims are only comparable when the measurement method matches. A single-direction run and a two-way average are different tests, and the U9 Xtreme's headline number belongs to the former category.
The car behind the number
The U9 Xtreme, previously called the Track Edition, is the flagship version of Yangwang's two-door electric hypercar, built in a run of 30 cars priced above ¥20 million, or about $4.36 million at the conversion cited, against ¥1.8 million ($392,000) for the regular U9.
It uses a 1200V architecture and four electric motors, one per wheel, for a combined 2220kW, more than double the standard U9's 960kW. The regular U9 produces 1680Nm and claims 0-100km/h in 2.36 seconds and a standing 400m time of 9.78 seconds; BYD has not published official acceleration figures for the Xtreme.
The standard U9 launched with a claimed 309.19km/h top speed and later reached 391.94km/h in testing before the Xtreme went faster still. The Xtreme also holds a Nürburgring Nordschleife lap of 6 minutes 59.157 seconds, the fastest recorded by a production electric vehicle.

What BYD says, and what it means
BYD executive vice-president Stella Li said the team was already reviewing data and planning the next step while celebrating the 496.22km/h run in Germany last year. "503.17km/h is a fantastic achievement, and it moves the benchmark for pure electric power even further ahead of where others might dream," she said.
The record is a marketing asset more than a sales one, given the 30-car build and seven-figure price. Its value lies in what it demonstrates about BYD's high-voltage, four-motor hardware, technology that can filter down to models more buyers can afford.

Australian connection
The standard U9 is not sold in Australia, but Nick Politis, a director of Eagers Automotive, ordered a U9 Xtreme in April 2026, with delivery expected in early 2027. That makes the record a local story for at least one Australian buyer, even though the model has no official retail presence in the country.
