Nissan has even set out to improve the car's insulation from the whine of the drivetrain, reassessing the placement of noise-cancelling material and indulging in Active Noise Control from the Bose sound system.
Finally (or possibly firstly, depending on how you look at it) there has been the usual deck-shuffling of light clusters, with the front getting rather dashing LED lamp signatures to the front and a more distinctive 'four ring' arrangement at the back.
What's it like?
Really rather convincing. Previous trips out in the GT-R would not last five minutes before the suspension was frantically thumbed into its 'Comf' mode. Here, on admittedly smooth Japanese roads, the softest setting was not required to reasonably satisfy one's aching spine.
Its engineers bridle at the suggestion of softness; what they've strived for, they say, is improved compliance for better traction, and there is that sensation - not plush or tremendously isolating, but sufficient to make the GT-R a better everyday prospect (obviously the point).
Similarly, the new steering does make junction navigation a little less bothersome, and work at the opposite end to make its responses more linear (and less in need of minor corrections) has also paid off.
A modest route hardly permitted a decent work out of the GT-R's formidable dynamic, but it's fair to say that when prodded, the car still responds with huge conviction. Revised throttle response, beyond a moment's pause for thought, is aggressive and then relentless. Nissan doesn't quote a 0-60mph time for the new Nismo, but the standard car is still below 3, and that'll be plenty good enough for most.
Work on the noise levels in an otherwise unchanged (and therefore still rather lumpy) cabin proves halfway decent. At slow speeds there's less obvious brouhaha from the engine bay, and perhaps a clearer note when worked, but in-between the experience is still overawed by massive road noise or the grumpy mewl of the transaxle.
Should I buy one?
Perhaps. There's a more rounded GT-R here, and in very few books will that be a bad thing. While UK roads may yet hobble the MY 14, hiving off the hardcore to squabble over the Nismo has certainly left behind a car better prepared for its idiosyncracies - and (probably) lacking none of its talent.However. By splitting its range in two and building a quicker GT-R, Nissan has given us the problem of ranking them, and the car doesn't quite sell comfort (or economy or luxury or beauty) quite well enough to seal the idea that it's a stellar all-rounder in the mould of, say, a 911.Deep down, certainly to all those that care enough to sign on the line, the GT-R is still likely to be about supercar-killing, tongue-swallowing speed. The yet more furious version offers an even bigger bang per buck, and short of the uprated suspension reducing us to tears or being bankrupted by the premium, that's the horse we'd choose to ride in on.
