Nissan GT-R has been revealed with a number of upgrades. Improved stability and better performance handling are main highlights of the new GT-R. Nissan says that the new GT-R is capable of lapping the 20.8 kms long Nurburgring in 7 minutes and 18.6 seconds. For the record, Ferrari Enzo has a lap-time of 7 minutes and 25.7 seconds.
Enhancements include engine tuning which has increased power output of the 550 PS 3.8 liter twin turbocharged V6 engine. RPM in mid and upper ranges have been upgraded and tuned so as to provide superior stability and handling at top speeds. An anti front roll bar, changes to dampers and springs as also body rigidity have given this car a refined feel.
The tuned engine ensures that 0-62 mph is completed within a short span of 2.7 seconds. Tuning to such an extent has been achieved by using high output injectors, new oil pan baffle and relief valve for the car. New cam bolts and torque carrying capacity of drive shafts have also been increased considerably. Price for the car will be revealed during launch.

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.
