Improved response, better stability and sharper handling, will be the hallmarks of the 2013 model year Nissan GT-R.
Nissan will reveal full prices and exact performance details closer to the car’s launch, but in the meantime the technical changes are outlined below:
Engine
- 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.
Chassis
- 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.
Body
- Reinforcements have been added to the dash panel bar and instrument panel member resulting in increased body rigidity and better suspension control.
