History[edit source]
The EP9 was built in 18 months, and debuted at the Saatchi Gallery in London, England.[1]

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.

Specifications[edit source]
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 (1,000 kW; 1,360 PS). The EP9 is both all-wheel drive,[2] and individual-wheel drive. The EP9 has an advanced torque vectoring system that can adjust the power output to each wheel.

The EP9's battery can last up to 265 mi (426 km) before it needs to be charged. Recharging takes 45 minutes, and battery replacement takes 8 minutes.

The EP9 is equipped with an active suspension, including a ride height controller that makes 200 calculations per second.[3]

The EP9's brakes are constructed by NextEV.

The car's chassis construction is all carbon fiber, and is based on the FIA Le Mans Prototype regulations. The exterior is also made of carbon fiber.

The vehicle's batteries weigh 635 kilograms. All of the carbon fiber in the car, in total, weigh at 364 kilograms. The total weight of the car is 1,735 kilograms (3,825 lb).[2]

Performance
The EP9 can accelerate from 0-60 mph in 2.7 seconds, 0-124 mph in 7.1 seconds, and 0-186 mph in 15.9 seconds. Its top speed is 194 mph (313 km/h). The EP9 has the third-quickest 0-60 mph time of any electric vehicle, behind Tesla's Model SP90D and P100D models when launched with Ludicrous mode.

Exterior
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) of downforce at 150 mph (240 km/h), 200% more than a Formula 1 car, allowing the EP9 to corner at 3 Gs.

Interior
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.
 * Dashboard screens - Both screens display performance data, but differ in function. The passenger-side screen displays only four measurements: the car's top speed, lap time, and lateral G-forces, and the driver's heart rate.
 * Center console screen - Displays performance data, lap times, and a track map with the car's current position.
 * Steering wheel screen - The steering wheel is a simplified version of NextEV's Formula E racing wheel, and is built by the same company.

World records
The EP9 set records for the fastest lap by an electric vehicle at the Nürburgring Nordschleife, Circuit Paul Ricard, Circuit of the Americas, and Shanghai International Circuit tracks.
