Nissan has announced the introduction of the 2012 model year GT-R – the car goes on sale in global markets beginning January next year. In a nutshell, the 2012 revisions have brought about more power to the VR38DETT block, to 550 PS at 6,400 rpm, with torque at 632 Nm from 3,200 to 5,800 rpm (up from 612 Nm), as well as improved economy and lower emissions.
As well as more power, the 2012 GT-R has a newly developed asymmetric suspension which compensates for greater weight on the driver’s side in RHD models, enhanced transmission ‘feel’ and a stronger body for extra rigidity and ever better handling.
The engine response and torque at mid- and low-speeds, and power at high revolutions, has been sinificantly improved, primarily from improved intake efficiency as well as exhaust emissions efficiency and increased exhaust valve cooling performance. The car also has reduced air flow resistance, thanks to a more compact under floor catalyser which improves emissions efficiency and reduces weight.
As for the transmission, the shift ‘feel’ and quietness has been refined thanks to a strengthened design of the shift fork arm and a firmer fixing bearing for the flywheel housing. Also, a special differential oil – namely R35 Competition Type 2189E in a 75W-140 viscosity – that was developed for competition is now used in every GT-R version.
As well as greater power and torque, the reinforcing of certain areas around the rear part of the engine compartment and dash panel delivers more responsive handling, and Nissan says a greater sense of the vehicle’s grip on the road is transmitted to the driver.
