Nissan has introduced a series of minor yet important updates to its GT-R model in Europe and the UK for 2010.
Front spring and damper rates have been changed to improve ride comfort while also assisting in steering response and “more accurate control of suspension movements”.
At the rear, the stiffness of the suspension radius rod bushings has been increased, giving improved feel and responsiveness during cornering.
The logic controlling torque distribution between the front and rear axles when the GT-R is manoeuvring at low speeds just after start-up, when fluids are cold, has been altered to reduce rear-axle ‘binding’. Furthermore, the logic in the gearbox has been changed to give a later downshift from sixth- to fifth-gear when being driven in automatic mode, but a more aggressive downshift pattern is adopted when changing down from fourth- to third-, and from third- to second-gear.
To improve cooling around the rear of the car, two additional NACA cooling ducts have been added to the carbon fibre underfloor diffuser which will provide additional cooling to the exhaust and gearbox. Furthermore, a new, larger diameter pipe connecting the oil cooler will reduce gearbox temperatures.
Another small, but significant update has been to the front transmission mount, which has been stiffened, reducing vibration through the driveline under high-load conditions.
The balance of the electonic brakeforce distribution bias has been moved slightly rearwards, giving greater braking stability in dry conditions, while a change in design of the rear brake cross spring has reduced noise and a modified air deflector increases rear brake cooling.
Changes to the emissions system now ensure GT-R is Euro 5 compliant, without loss of output or performance, with CO2 emissions having dropped by 3g to 295g/km.
Visually, front and rear bumpers now benefit from a double coat of clear paint, giving a deeper colour finish, while inside the speedometer and rev counter now sport gun metallic finish surrounds.
Finally, uprated insulation has been fitted to the rear seats, further improving cabin refinement.
