Xiaomi has made the highest-end version of its inaugural EV all but official ahead of its formal launch. The SU7 Ultra is backed to produce just over 1,500 horsepower and to go from 0 to ~62 miles per hour in less than 2 seconds thanks to its triple motor system. It also comes with high-tech components such as cutting-edge batteries and "professional racing-grade" brakes, tipped to push its starting price into six figures - and not just in RMB.
