To paraphrase Nissan, much of the evolution of the R35 GT-R has been focused on the R or racing aspect of the car. This year's modifications are more about GT or grand touring component of the car's personality, which will hopefully broaden the uber-Nissan's appeal.
According to the company, these alterations have improved the GT-R's ride "dramatically". Much of the improvement comes from the tyres, which now feature revised materials and inner structure.
The shocks' damper rates have been tweaked to improve both cornering and rough road stability. Brake noise, it's claimed, has been quietened, while vibrations through the steering wheel and elsewhere have been also been reduced.
Australia-bound Premium Edition models will have the RAYS "double spoke" alloy wheels (below) fitted as standard.
The Track Edition engineered by Nismo (below) becomes a permanent trim level at the top of the GT-R tree. It will be available on GT-Rs sold in Japan and other overseas markets, but won't be coming to Australia for now.
Upgrades standard on all Track Edition models include RAYS forged alloy wheels, revised suspension and stabilisers, Dunlop SP Sport Maxx GT 600 DSST tyres, and extra adhesive bonding throughout the body to increase structural rigidity.
Released in tandem with the general 2015 range is a 45th Anniversary limited edition model (below). Restricted to just 45 units, this special model looks to be a Japan-only proposition.
The 45th Anniversary model is available only in a paint colour dubbed "silica brass", which is a homage to the R34 Skyline GT-R M-Spec model aimed at mature buyers. The only other notable changes are a 45th Anniversary emblem on the centre cluster and a build number plaque in the engine compartment.
The output of the GT-R's 3.8-litre twin-turbo V6 remains unchanged with 404kW of power on tap. As before it's hooked up to a six-speed dual-clutch transmission and a sophisticated all-wheel-drive system.
