Papenburg, Germany (September 20, 2025) – YANGWANG, the luxury sub-brand of BYD, has redefined the limits of performance by setting a new world production car speed record with its U9 Xtreme (U9X) hypercar. Achieving an astonishing 308.4 mph (496.22 km/h) at the ATP Automotive Testing Papenburg track, the U9X is now officially the fastest production car in the world – and it’s fully electric.

Record-Breaking Performance
