Supercars and racing cars including solar cars show the future. Here we see the trend to more motors and motor controllers per car - part of the trend to power electronics becoming more important than batteries. Toyota tells us that sometimes the motor controller will cost more than the motor. Two traction motors per EV is now common and three are seen in an increasing number of vehicles with this example having four.
This week, at a launch event at the Saatchi Gallery in London, UK, electric car company NextEV unveiled its brand, NIO. NextEV say their visionary electric car brand will help users rediscover the 'joyful lifestyle' of car ownership by creating inspiring vehicles that deliver superior performance, a new benchmark for aesthetic design and unique user experiences.
Additionally, the company unveiled its electric supercar, the NIO EP9, which has achieved a new lap record at the Nürburgring Nordschliefe. On October 12th 2016, the EP9 lapped the 20.8km 'Green Hell' in 7m 05.12s, beating the previous EV lap record held, marking it out as the fastest electric car in the world. Additionally, on November 4th, it smashed the EV record at Circuit Paul Ricard in France, recording a time of 1m 52.78s, eclipsing the previous record of 2m 40s.
With four high-performance inboard motors and four individual gearboxes, the EP9 delivers 1-MegaWatt of power, equivalent to 1,360PS. The EP9 accelerates from 0-200kph in 7.1 seconds and has a top speed of 313kph. With an interchangeable battery system, the EP9 is designed to be charged in 45 minutes and has a range of 427 kilometres.
The carbon cockpit and chassis embodies a new approach to performance vehicle design to handle the physical demands of a car with 3G cornering capabilities, with added structural solidity and aero efficiency. The EP9 is capable of achieving 24,000 Newtons of downforce at 240kph.
The EP9 features a visionary integrated e-control structure and sensor system layout, which could fit the latest autonomous driving technology. Additionally, it utilises NextEV's intelligent, user-friendly interactional design concept, which provides a joyful experience for users with digital interaction and instant sharing.
NextEV Founder and Chairman, William Li, said: "Today we 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. 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."
