Setting a time of 6minutes, 45.90seconds, the EP9 broke the Radical's long-standing 'Ring record for a road-legal car by 2.1sec. Radical's time was 6m 48.0sec.
Nio previously set a lap time of 7:05.12 in October last year - almost 20 seconds slower than its latest record-breaking attempt - but still enough to place it sixth overall, as well as garnering it the accolade of the fastest electric vehicle around the Nordschleife.
It's still almost 35 seconds slower than Stefan Bellof's 1983 lap, which holds the title of fastest ever Nürburgring lap by any car, though.
The EP9 has a power output of one megawatt; the equivalent to 1342bhp, and a top speed of 194mph. The model can reach 62mph in 2.7sec and 124mph in 7.1sec.
In claiming the overall 'Ring record, the Nio has reaffirmed its electric 'Ring record, as well as snatching the four-wheel drive lap record for a road-legal production car.
Only twenty examples of the EP9 will be made, despite the company having previously capped production at six, at a cost to customers of $1.48million (around £1.15million).
