Not content with setting a production car top speed record last year with its U9 XTreme, BYD brand Yangwang has had another go, and gone even faster. 

 

During the run on Sheikh Khalifa Bin Zayed International Road in Abu Dhabi, UAE, 24 Hours of Le Mans winner Marc Basseng hit an astonishing 312.65mph, pushing a road car across the 500kmh barrier (503.16kmh) for the first time. That's up from the U9 XTreme's 308.33mph mark.
