This car feels like a race track refugee. It is. As you discover once underway. First the figures: in this Nismo model, 62mph from rest is barbequed in just 2.8s, 100mph flashes by in under 8s and if you have an airport runway on hand, you'll hit 196mph before the electronics prevent you reaching the magic 200mph mark.
Under the bonnet, that thundering 24-valve V6 here generates 600hp - quite a change from when we first tested the standard version of this car a decade ago, which put out 'just' 478hp. Now, as then, it drives all four wheels via a dual-clutch six-speed semi-automatic gearbox with steering wheel paddles for rifle-quick 0.2 second changes. You can understand why at its original launch, this car embarrassed Porsche by lapping their backyard, Germany's Nordschliefe Nurburgring racetrack, faster than a 911 Turbo costing nearly twice as much. Even when you're not on track, the whole experience is addictive in the extreme. And 'extreme' is a word you keep using with reference to this Nissan. No attempt has been made to refine or culture its sensibilities; if a British Touring Car Championship driver were to lend you his race car for a quick blast up your favourite B road, then this, you feel, is the kind of experience you'd get. A rigid body structure and race-tuned suspension give confidence-building stability through quick lateral transitions and high overall cornering speeds. Providing the grip are sticky 20-inch tyres, wrapped around smart "RAYS" machine-finished forged aluminum wheels.
Apart from this Nismo version's extra power, in its latest form - and this will be its last form - it features some subtle tweaks. Like bespoke Dunlop front tyres; and turbochargers taken from the GT3 race car with fewer, thinner vanes. At this level in the GT-R range, you also get lighter weight - this Nismo version tips the scales at 1,703kgs - plus revised damping and carbon-ceramic brakes. Otherwise, it's pretty much the standard GT-R recipe.
The ride isn't actually as stiff as I was expecting - and you can tailor its tautness via this dash-mounted switch. There's another button to alter stability and traction settings too. You'd be well advised though, to decide upon your various drive selections before really starting to flex your right foot because once you do, your eyes are going to need to be glued on the road ahead if you're to stay out of the hedge and/or on the right side of your local magistrate; and that's in the dry..
And refinement? Well the thundering engine certainly makes its presence felt, but not to the point where you'd be shy to take this car on a cross-continental journey. But that would be a waste of its talents. It's a supercar accessible to almost anyone, yet rewarding enough for the most demanding enthusiast. It's still an astonishing achievement.
