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 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 313 km/h (194 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.
- 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.
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.
|Circuit Paul Ricard||1:52.78|||
|Circuit of the Americas||2:11.30 (driver)
|Shanghai International Circuit||2:01.11|||
The EP9 used racing slicks, so the published times are not comparable to those by cars in street-legal states.
