Pure-electric cars have been around for decades but only in the past five years or so have the mainstream manufacturers really started to take them seriously -- prompted by tightening rules over when and where conventionally powered vehicles can be driven, and battery technology that has made them more usable in the real world.
As such, there have already been a few upstarts, most notably Elon Musk's Tesla, which confounded the giant car brands by launching precisely the vehicle they said was impossible at the time: a luxury executive saloon with a range of more than 200 miles.
Truth be told, Tesla's offering will still out-accelerate NextEV's NIO EP9 up to a point. But the NIO EP9's pace has been judged over more than just a quarter-mile drag race; this one-megawatt (1,341bhp) creation has, in fact, proven its mettle around the famed Nurburgring in Germany, a 12.9-mile monster of a race circuit known simply as 'The Green Hell.'
The 195mph NIO EP9 has lapped the track, NextEV claims, in just 7m 05.12sec, or around 17 seconds faster than the previous electric car record. Indeed, to put it in context, the EP9's time is only beaten in the all-time list by four road-legal cars, two of them thinly disguised racers, and the other two supercars from Porsche and Lamborghini.
And yet the EP9 can be recharged from flat in as little as 45 minutes, to offer a range of more than 265 miles. There is no guarantee that it will deliver this in production, but if it does, it has the potential to rewrite the rules of the hypercar market.
NextEV has committed so far to six examples, all reserved for the company's initial investors. But, even with each EP9 costing around $1.2 million to build, the firm may consider an additional small production run, if only to raise its global profile further.
China is a hotbed of EV activity because crippling pollution in many cities has persuaded Beijing to open up that side of the business to 'non-automotive' companies. Some, like NextEV and telecoms giant-turned EV developer LeEco, appear to have enough backing to not only deliver a car, but to reach global customers.
China's growing electric vehicle market
They are not alone in sharing that ambition. Earlier this year, the state-owned Beijing Auto International Corporation launched an EV sub-brand called ArcFox with a creation called the ArcFox-7. It has a 603bhp electric motor, is made mostly out of carbon fiber and can reach 60mph in less than three seconds -- though its top speed is more modest than the EP9's, at 155mph. Its range is more limited too, at 186 miles.
Another brand, TechRules, has been testing an innovative hybrid supercar around the UK's F1 GP venue, Silverstone.
The car carries the unusual moniker TREV, which actually stands for Turbine-Recharging Electric Vehicle, and it mixes plenty of cutting-edge tech -- including carbon fiber construction, a small lithium-ion battery pack and four-wheel drive -- to deliver a theoretical top speed of more than 217mph, while potentially running for more than 1,242 miles between fill-ups.
Even the choice of fuel is open to interpretation; one version of the car, called AT96, can run on aviation fuel, diesel or petrol, while the other, called GT96, is powered by natural gas.
Qiantu Motor's K50, another 2016 debutant, sits just below supercar territory, but even so, its mix of aluminum and carbon fiber construction, and four-wheel drive through a pair of electric motors, brings performance that will match many European creations -- a top speed of 125mph and, more importantly, 0-60mph in less than five seconds.
Luxury car manufactures enter market
Still, the Chinese are not likely to have the 'electric hypercar' space to themselves for very long. Desperate not to be beaten to the punch, the established car brands are now clamoring to get their own all-electric offerings to market.
The giant VW Group is fast-tracking development of electric components and already showcased one of the first cars that will use them -- the Porsche Mission E. It's a four-door electric saloon, but its performance will rival that of many sports cars and it should introduce new standards for fast-charging, too.
Even the supercar elite who normally exist above the general industry are not immune to the demand for greater environmental credentials in their cars.
The fastest vehicles recently offered by Ferrari and McLaren have both featured electrification, and the British company has already admitted it is working on an all-electric supercar.
Interestingly, though, these are names with history, so they have a reputation to protect -- whereas NextEV and its like have hundreds of millions of dollars of investment and, at the same time, nothing to lose.
Winning over customers is about more than numbers, though. And this, in fact, may ultimately prove a bigger test for NextEV, TechRules and ArcFox than the technical challenge of getting around the Nurburgring (or, for that matter, actually bringing their cars to market at all).
In the past, buyers with the wherewithal to spend more than a million dollars on a car have been more drawn towards those brands with heritage. The Chinese brands must hope that the same does not apply to those who want not just an exclusive supercar, but also one that they can plug into the wall every evening.
