The MY13 Nissan GT-R features a number of updates and one very special new addition – thanks to the GTROC!
In January of this year AutoMission organised another of it’s fantastic tours to Japan. A daily blog of the event can be found on the blog site of this website. The event featured, amongst other things, a vist to Nissan’s DNA Centre at Zama, the Tokyo Auto Salon and a VIP guided tour of the GT-R engine assembly and test plant. This was the first time anyone other than a few invited dignatories had ever been invited to see the secret production plant where the engines are made and tested. If that wasn’t enough then going into the temperature and humidity controlled clean room where the engines are assembled had to be something quite special.
After the visit members of the GTROC met with some very senior Nissan Executives, not least of which was Nissan-Renault Global Head of Marketing: Simon Sproule. It was during a discussion with Simon and some of his team that we discussed current projects and future development plans. But one comment made has clearly already been taken on board. With every engine individually made by one person it was suggested that each engine should have it’s own plaque with the name of the engine builder. A hark back to the days when all cars and all engines were hand made perhaps but certainly a stamp of pride in every engine built and a really ncie touch that every new owner can see who it was that put their engine together.
For 2013 all new GT-R engines will have a plaque detailing the name of the engine builder. All thanks to some suggestions from GTROC members. The next tour to Japan is in January 2013 when a lot more GTROC members will be able to experience the trip of a lifetime, this time with a visit to the GTR Assembly Plant in Tochigi!
But what else is there about the MY13? The 2013 model year GT-R features a round of updates
- Twin-turbocharged V6 engine modified to offer even better response
- Suspension upgrades for improved ride comfort and sharper handling
- 0-62mph time drops 0.1 seconds to 2.7 seconds
- Capable of lapping the Nürburgring circuit in 7min 18.6 seconds
- On sale in the UK in Spring 2013
Improved response, better stability and sharper handling – those are the highlights of the 2013 model year Nissan GT-R.
On sale next Spring, the four-wheel drive supercar has received a round of enhancements aimed at subtly boosting the responsiveness of its 550PS 3.8-litre twin-turbocharged V6 engine while improving ride and handling at the same time.
Applying lessons learned from this year’s Nürburgring 24-Hour race to the roadgoing GT-R, engineers have improved response in both the mid- and upper-rpm rev ranges, increased body rigidity and made changes to the dampers, springs and front anti-roll bar.
As a result, the MY13 GT-R is more responsive, has better high-speed stability and a more refined ride. The 0-62mph time has dropped to 2.7 seconds (from 2.8 seconds for the MY12) while the car is even faster around the Nürburgring, lapping the famous German circuit in 7min 19.1 seconds when undergoing testing in May this year.
Kazutoshi Mizuno, creator of the GT-R, has revealed that 0.5 seconds were lost to traffic on that hot lap, indicating that the MY13 GT-R is capable of a 7min 18.6 seconds lap. That compares to 7min 21 seconds for the MY12 GT-R.
Nissan will reveal full prices closer to the car’s launch, but in the meantime the technical changes are outlined below:
- New high-output injectors more concisely control fuel injection to improve mid-range and high-rpm response.
- A new relief valve for the turbocharger bypass suppresses the rapid decrease of forced injection pressure, again helping to sustain response.
- A new oil pan baffle helps maintain more stable oil pressure and reduces rotational friction especially during high-performance driving.
- After measuring the roll centre of the GT-R when cornering and taking deflection of the bushes and tyres into account, engineers have updated the suspension set-up with revisions to the dampers, springs and front anti-roll bar to lower the centre of gravity.
- New cam bolts have been installed on the front suspension to improve camber accuracy and stability when cornering.
- The torque carrying capacity of the driveshafts to the hub bearings has been increased to improve reliability in high-stress situations, such as track driving.
- Reinforcements have been added to the dash panel bar and instrument panel member resulting in increased body rigidity and better suspension control.
