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 previously), 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 better handling.

The engine response and torque at mid- and low-speeds, and power at high revolutions, has been significantly 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 the 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.

At the same time, more precise production methods, accompanied by advancements made in the vehicle body, have improved the inter-vehicle detection capability. This has been achieved by a more rigid, highly-damped vehicle body and changes in the positioning of the sensor. Additionally, a more accurate acceleration sensor has been placed in areas with higher sensitivity in the vibration testing of each vehicle body.

Meanwhile, accounting for the added weight of the driver in a right-hand drive vehicle, coupled to the fact that the propeller shaft for the front wheels is located on the right side of the vehicle, the GT-R’s suspension in RHD versions has now been set asymmetrically.

For the front suspension, there’s a harder spring rate on the left side, while at the rear, the suspension arm has been installed upwards on the left side and downwards on the right. This means an imbalanced wheel load when the car is stationary, but which is equalised during driving, providing improved responsiveness, smoothness and steering feel, as well as enhanced cornering stability and riding comfort.

Elsewhere, the interior gets minor tweaks – the instruments placed in front of the driver have been enhanced by the addition of blue lighting inside the tachometer ring to match the shift position indicator light, and the Bose audio system’s woofers have been changed to Bose Precision Sound System woofers developed for the Egoist grade, for improved sound quality. Also, a rear view camera is now standard on all models.

There’s also a Track Pack custom option, available for the Pure Edition. Jointly developed with NordRing company in Japan, it features a suspension, air guide for both front and rear brake cooling and aluminium-alloy wheels made by Rays (the last with a black quartz chrome shade coating).

The front spoiler – with a carbon air duct – has been exclusively made for this edition, and is installed as a set. To reduce the vehicle’s weight, the edition features a two-seat configuration (without rear seats, with quilted fabric mats), though one can opt for combination seats made with genuine leather and high-grip fabric that have been newly developed for the “For Track Pack” option.
