2012 Nissan GT-R
Engine
By improving the Nissan GT-R's engine efficiency, its fuel economy has been decreased from 12L to 11.8L/100 Kms, while engine output rises significantly from 390kW to 404kW (550PS) from 6,400rpm with maximum torque of from 612 to 632Nm (64.5kgfm) from 3,200 to 5,800 rpm.
Engine response and torque at mid- and low-speeds, and power at high revolutions, has been significantly improved, mainly due to:

Engine response and torque at mid- and low-speeds, and power at high revolutions, has been significantly improved, mainly due to:
- Improved intake efficiency
- Better air flow resistance, which has been reduced by the addition of an intake manifold fitted to the head of each unit and the use of resin in the enlarged air intake duct for the intercooler
- Improved exhaust emissions efficiency and enhanced control
- Reduced air flow resistance thanks to a more compact under floor catalyzer which improves emissions efficiency and reduces weight
- Improved exhaust valve cooling performance by the adoption of a newly-designed metallic sodium-filled valve. At the same time, valve control timing, the air mixture ratio and ignition timing have been improved
