NextEV claims that its Nio EP9 electric supercar has lapped the Circuit of the Americas in Texas while driving autonomously in 2min 40.33sec, which is just 19sec slower than it managed when a driver was behind the wheel.
The Nio brand released a video with footage from the car's timed lap, although coverage of the whole lap is yet to be shown.
The Chinese supercar is a limited-run 1360bhp all-wheel drive two-seater. It has four inboard electric motors and gearboxes developed in collaboration with NextEV’s Formula E team. The car’s combined power output equates to one megawatt and enables it to accelerate from 0-62mph in 2.7sec. Top speed is 194mph.
NextEV says the EP9 can deliver up to 2.53g in lateral cornering and 3.3g longitudinal under braking. It claims the car produces twice the amount of downforce of an F1 car – or 24,000 Newtons' worth at 149mph – and has been built to FIA LMP1 specifications for safety. It won’t be going racing, however.
