Engine and chassis updates for elevated performance
Nissan recently announced a second round of major performance updates to its GT-R flagship supercar. The improvements are said to be borne out of its endless passion for improvement and motorsport activities at the Nurburgring.
The result of the updates has improved acceleration as well as laptimes at the ‘Ring’. It’s now 0.1 seconds faster accelerating from 0 to 100km/h clocking in at 2.7-seconds. It officially clocked in at 7 minutes 19.1 seconds earlier this year; nearly two seconds faster than the outgoing 2012 version which managed a laptime of 7 minutes and 21 seconds.
Late last year, the venerable ‘Godzilla’ was given a mid-life makeover as well performance tweaks; the major update being a transmission update due to problems with transmission failure due to the launch control system.
The new performance updates in the VR38DETT engine for 2013 include higher output injectors, new relief valve for the turbocharger bypass to prevent rapid pressure loss for better engine response. A new baffle plate has also been added to the oil pan to stabilize oil pressure and reduce rotational friction in the oil pan. Motul Competition Oil will now be offered as an engine oil option for high-performance inclined customers.
More attention was also given to the chassiswork with the improvement of the suspension to achieve a lower center of gravity. Cam bolts have also been added to the front suspension for more flexible camber adjustment. To handle the extra load and optimize power delivery to the wheels, the driveshafts have also been upgraded for high-stress situations such as competition (track) driving.
To further improve driving stability and steering response, the dashboard panel bar and instrument cluster member have also been reinforced.
The 2013 Nissan GT-R is set to go on sale on November 19 in Japan. Other markets are expected to follow afterwards. While not officially available through the dealers, the Nissan GT-R has been selling through grey market car dealers in the Philippines.
