BYD’s Yangwang U9 Xtreme Sets New Top Speed & Nürburgring Lap Records - CleanTechnica

BYD recently announced that its Yangwang U9 Xtreme hypercar set new records, including a top speed of 308.37 mph (approximately 496 km/h) and an electric vehicle (EV) lap record at the Nürburgring. These achievements not only provide BYD with significant bragging rights but also challenge the dominance of traditional fossil-fueled hypercars. The U9 Xtreme’s performance is powered by a 2220 kW (2977 hp) motor system paired with an 80 kWh battery featuring an advanced double-layer cooling structure that enables a 30C discharge rate, contributing to a 133% increase in power and a 40% improvement in heat exchange efficiency. The technological advancements in cooling and power electronics, including the use of silicon carbide (SiC) components, may have broader implications beyond the hypercar segment. BYD’s innovations could enhance the reliability and efficiency of mainstream electric vehicles, especially in extreme heat conditions, and potentially improve charging
