The Nio EP9 is a battery-powered, two-seat sports car manufactured by RML group on behalf of Chinese electric car company Nio, not assisted by their Formula E racing division. The name EP9 stands for Electric Performance 9.
However, it is not a road-legal vehicle for roads,and none of the 16-production model EP9s were ever registered for road use. The EP9 is purely designed for track use only and does not comply with the laws and regulations to be registered in China. None of the 16-production model EP9s were ever exported and registered for road use outside China so far.
Each of the EP9's wheels has its own motor and transmission. Each motor has 335 hp, giving the car a total power output of 1341 hp. The EP9 is both all-wheel drive, and individual-wheel drive. The car has an advanced torque vectoring system that can adjust the power output to each wheel.
The EP9's battery can last up to 427 km before it needs to be charged. Recharging takes 45 minutes, and battery replacement takes 8 minutes as the batteries need to be removed when recharged.
The car is equipped with an active suspension, including a ride height controller that makes 200 calculations per second.
The car's brakes are developed and constructed by U.K manufacture Alcon.
The car's chassis construction is all carbon fibre, and is based on the FIA Le Mans Prototype regulations. The exterior is also made of the same material.
The vehicle's batteries weigh 635 kg. All of the carbon fibre in the car, in total, weighs 364 kg. The total weight of the car is 1735 kg.
The EP9 can accelerate from 0 to 100 km/h in 2.7 seconds, 200 km/h in 7.1 seconds, and 300 km/h in 15.9 seconds, as demonstrated by Richard Hammond in The Grand Tour. The car can achieve a top speed of 313 km/h.
