Right now, a sheet of paper in a Yokohama-based office is on fire. How do we know this? On this sheet of paper, some Nismo engineers have scrawled a prototype GT-R that will be the fastest Nissan ever.

And it’ll most definitely be on fire because Nissan told TopGear.com that this special Nismo GT-R will lap the Nürburgring in under 7m 18s, comfortably eclipsing the current car’s lap record, and moving it further to the top of the unofficial King of the ‘Ring table. Oh, and that’s quite a bit faster than Porsche’s new GT3, too, a claimed 7m 22s. Woah.

We first got wind of this Super GT-R a few months back, when Nismo - that’s Nissan Motorsport - officially unveiled its global HQ in Yokohama, Japan, making the legendary tuner an integral part of Nissan’s business. And at the time, Nissan CEO Carlos Ghosn said: “It would be unthinkable for us to develop a range of Nismo road cars without including the GT-R. The GT-R Nismo will be special…”

So on the launch of Nissan’s 370Z Nismo model - which you can read about here - a Nissan spokesman told TG.com how this Super GT-R will be the “hardest GT-R ever”. That’s quite a firework, but then the standard GT-R, if you can call it ‘standard’, is a bombastic piece of kit.

Nissan was, naturally, extremely coy about the details, only telling us that the car is currently in the development phase, but “will be of great value and offer the same concept as other Nismo products: more power, better handling and improved looks.”

When pushed on power gains, there were some nervous smiles, most probably because rocket science is a risky business. The current GT-R comfortably produces 545bhp and 465lb ft of torque, but Nissan told us the Nismo version will probably produce “more than 570bhp”.

Undoubtedly, there will be suspension and aero tweakery too, though we’ll have to wait and see. Stay tuned, as Nissan tells us it will appear in the second half of 2014. That, dear Internet, will be the definitive Nismo product, so expect some thunder…

Sub 7m 18s, in a Nissan. Sheesh.
