BYD’s all electric hypercar hits record top speed during latest run
Published: 20 Sep 2025It’s official: the Yangwang U9 Xtreme (formerly called the Track Edition) is now the fastest production car in the world, having hit 308.4mph at ATP Papenburg’s high speed oval in Germany. It dethrones the Bugatti Chiron Super Sport 300+, which managed 304.8mph in 2019, having already toppled the Aspark Owl (272.6mph) and Rimac Nevera R (268.2mph). It gets 2,978bhp, over double the ‘regular’ car’s 1,288bhp, from four electric motors (which utilise the world’s thinnest super-silicon steel – 0.1mm – in mass production), each of which can spin at up to 30,000rpm.
