Meet the YangWang U9 Xtreme, a 3,000-horsepower electric missile that just clocked 308.4 mph (496.22 km/h) and sent shockwaves through the speed freak community. What Makes the U9 Xtreme Tick? The U9 Xtreme is a proper science experiment gone wild:Four electric motors putting out a combined 2,978 hp —that’s double the standard U9. Bugatti’s 300+ mph run was a once-in-a-decade flex, and now a Chinese EV has casually bettered it. Only 30 units of the U9 Xtreme will ever exist.
