NIO EP9: The Knowledge

NextEV has unveiled its all-new NIO EP9 electric supercar, which has just broken the EV lap record at the Nürburgring Nordschliefe thanks in part to its 1MW powertrain

 

 

Electric car company NextEV has unveiled its first car, the NIO EP9. The electric car brand has been designed to 'help users rediscover the ‘joyful lifestyle’ of car ownership' through its staggering performance and 'unique user experiences'.

Earlier this year, the EP9 achieved a new lap record at the Nürburgring Nordschliefe of 7m 05.12s, beating the previous EV lap record held by over 15 seconds. NextEV also took the lap record at Circuit Paul Ricard in France, recording a time of 1m 52.78s, eclipsing the previous record of 2m 40s.

The car is built around four high-performance inboard motors that transfer power through four individual gearboxes. The EP9 delivers 1-MegaWatt of power, equivalent to 1,360PS allowing the car to accelerate from 0-200kph in 7.1 seconds and has a top speed of 313kph.

The car has been designed around an interchangeable battery system, with the two lithium-ion units located in either sill. The EP9 is capable of being charged in 45 minutes and offers a driving range of 427km. The four motors deliver a combined 6334Nm of torque, with the EV drivetrain also offering torque vectoring for improved vehicle dynamics. 

"We have launched our electric supercar that broke the record at the Nordschliefe. The NIO EP9 was born to push limits and is the first stage of automotive production for NIO," said NextEV founder and chairman, William Li. "It is a statement of our vision and technical and manufacturing capabilities. It is a best-in-class product that showcases what is possible with electric vehicles. We believe that when the car ownership experience exceeds expectations, electric vehicles will become the natural choice for everyone, leading to a more sustainable tomorrow. And with that, our vision of a blue sky will come true."
