The NIO EP9 is an electric-powered, two-seat sports car manufactured by NIO, assisted by their Formula E racing division. It holds several track records.
Developed and built in 18 months, the EP9 debuted at the Saatchi Gallery in London, England.
Six EP9s have been sold to NIO investors for US$1.2 million each. NIO has announced that ten additional EP9s will be sold to the general public.
Each of the EP9's wheels has its own motor and transmission. Each motor has 335.25 horsepower, giving the car a total power output of 1,341 hp (1 MW; 1,360 PS). 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 (265 mi) before it needs to be charged. Recharging takes 45 minutes, and battery replacement takes 8 minutes.
The car is equipped with an active suspension, including a ride height controller that makes 200 calculations per second.
The car's brakes are constructed and developed in house by NextEV.
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 (1,400 lb). All of the carbon fibre in the car, in total, weighs 364 kg (802 lb). The total weight of the car is 1,735 kilograms (3,825 lb).
The EP9 can accelerate from 0-62 mph (100 km/h) in 2.7 seconds, 200 km/h (0-124 mph) in 7.1 seconds, and 300 km/h (0-186 mph) in 15.9 seconds. The car can achieve a top speed of 350km/h (217 mph).
The EP9's rear wing is adjustable between three settings: parked, low-drag, and high-downforce. The EP9 produces 24,000 newtons (5,395 lbs or 2447 kg) of downforce at 240 km/h (150 mph), similar to a Formula One car, allowing the EP9 to corner at 3.0 Gs.
The interior, like the exterior and chassis, is made entirely of carbon fiber. There are four screens: one on the driver's side of the dashboard, one on the passenger's side of the dashboard, one on the center console, and one on the steering wheel.
The EP9 set the record the fastest lap by an electric vehicle for the Circuit of the Americas, Shanghai International Circuit and the Circuit Paul Ricard tracks. It also set the record for the fastest lap by an autonomous vehicle at the Circuit of the Americas track.
The EP9 used racing slicks, so the published times are not comparable to those by cars in street-legal states.
