Nissan has introduced a series of minor but key updates to the GT-R to maintain its position as the definitive accessible supercar.
Under the skin, by changing the front spring and damper rates, the ride comfort is improved, while handling becomes even more dynamic thanks to improved responsiveness and more accurate control of suspension movements.
At the rear, the stiffness of the suspension radius rod bushings has been increased, giving improved feel and responsiveness during cornering.
The logic controlling torque distribution between the front and rear axles when the GT-R is manoeuvring at low speeds just after start-up, when fluids are cold, has been altered to reduce rear-axle ‘binding’. Furthermore, the logic in the gearbox has been changed to give a later downshift from 6th to 5th when being driven in automatic mode, but a more aggressive downshift pattern is adopted when changing down from 4th to 3rd, and from 3rd to 2nd gear.
To improve cooling around the rear of the car, two additional NACA cooling ducts have been added to the carbon fibre underfloor diffuser which will provide additional cooling to the exhaust and gearbox. Furthermore, a new, larger diameter pipe connecting the oil cooler will reduce gearbox temperatures.
Another small, but significant update has been to the front transmission mount, which has been stiffened, reducing vibration through the driveline under high-load conditions.
The balance of the electonic brakeforce distribution bias has been moved slightly rearwards, giving greater braking stability in dry conditions, while a change in design of the rear brake cross spring has reduced noise and a modified air deflector increases rear brake cooling.
Changes to the emissions system now ensure GT-R is Euro 5 compliant, without loss of output or performance, with CO2 emissions having dropped by 3g to 295g/km.
Visually, front and rear bumpers now benefit from a double coat of clear paint, giving a deeper colour finish, while inside the speedometer and rev counter now sport gun metallic finish surrounds.
Finally, uprated insulation has been fitted to the rear seats, further improving cabin refinement.
Upgraded Navigation & Audio
Since September deliveries, the GT-R has been equipped with Nissan’s next generation combined audio and navigation system, offering improved ease-of-operation, new and updated features. Indeed, the GT-R is the first Nissan model to be equipped with the new system.
At its heart is a Hard Disk Drive (HDD) navigation system with 40GB of memory space. This makes for faster operation and greater data storage capacity.
Among the many benefits are vastly extended mapping which now includes Turkey, Eastern Europe and Russia, as well as a new easy to follow 3D navigation guidance with improved graphics and a more realistic depiction of the road and landmarks ahead.
The resolution of the new 7 inch screen is up to four times better than the previous generation system.
Real time traffic information is supplied via RDS-TMC, but quicker operation allows the system to offer re-routing in a fraction of the time.
Users have access to Point Of Interest (POI) information supplied by Michelin, with comprehensive information on restaurants, services, museums and other tourist attractions in 20 major European cities.
And, like the GT-R’s existing display, the new generation system continues to use a touch-screen interface, maximising both ease of use and safety not only for the navigation, but also for other functions such as Bluetooth phone connectivity and entertainment. It is also possible to operate the system using voice recognition.
On-screen instructions can be displayed in eight different languages – English, French, German, Spanish, Italian, Portuguese, Dutch and Russian – while voice recognition is supported in seven – English, French, German, Spanish, Italian, Portuguese and Dutch.
Another benefit of the HDD information and entertainment system is the incorporation of a 9.3GB Music Box library which can store music from up to 300 CDs. The download takes place automatically when a CD is inserted into the CD player, if selected.
But for those who want a wider music selection at their fingertips, the system also allows iPod/USB connection with full control via the screen and/or steering wheel switches. In addition, song, artist and album information is displayed on the screen.
Other audio devices can be played via the unit’s Bluetooth Audio Streaming function.
