Nissan said that it has also altered the logic controlling torque distribution between the front and rear axles when the GT-R is maneuvering at low speeds to reduce rear-axle 'binding'.
The logic in the gearbox has been changed to give a later downshift from 6th to 5th when the car is being driven in automatic mode, but a more aggressive downshift pattern is adopted when the driver changes from 4th to 3rd, and from 3rd to 2nd gear.
Another improvement for the 2011 MY GT-R is the addition of two NACA cooling ducts to the carbon fibre underfloor diffuser for extra cooling to the exhaust and gearbox while a new, larger diameter pipe connecting the oil cooler promises to reduce gearbox temperatures.
The list of changes also includes a stiffened front transmission mount to reduce vibration through the driveline under high-load conditions.
Furthermore, the balance of the electonic brakeforce distribution bias has been moved slightly rearwards which Nissan says gives greater braking stability in dry conditions. A change in design of the rear brake cross spring is said to reduce noise while a modified air deflector increases rear brake cooling.
Nissan also claims that changes to the emissions system now ensure that the GT-R is Euro 5 compliant, without any loss of output or performance, with CO2 emissions having dropped by 3g to 295g/km.
The Japanese automaker has also fitted uprated insulation to the rear seats to improve improving cabin refinement.
The only visual upgrades for the 2011MY GT-R concern the front and rear bumpers that benefit from a double coat, giving a deeper color finish, while inside, the speedometer and rev counter now sport gun metallic finish surrounds. Finally, the new model year GT-Rs are equipped with Nissan's next generation audio and navigation system that features 40GB of memory space.
