It’s done it again – not content with becoming the world’s fastest production car last year, the Yangwang U9 Xtreme has officially broken the 500 km/h mark earlier this month, setting two new Guinness World Records in the process.

Whereas the previous record was set at the Automotive Testing Papenburg (ATP) oval in Germany, this time BYD’s engineers set off with an improved U9 Xtreme to Abu Dhabi, the same capital city where the über-luxurious Altior sedan was revealed this week.

Officials closed a ten-kilometre stretch of the Sheikh Khalifa Bin Zayed International Road (E11) in Al-Dhafra for the renewed top speed attempt, held over two days. The desert location and the road’s regular public use meant that it had to be swept before each attempt, with further inspection required to ensure stray brush wires didn’t puncture the Giti tyres.
