Official: 2013/2014 Nissan GT-R Gets Minor Upgrades

Following earlier rumours of increased performance, an improved gearbox, an improved cabin with new trim and a revised exterior styling, we can now officially confirm the release of the 2013/2014 Nissan GT-R and the upgrades to the latest version of Godzilla.

Nissan has released information on the new 2013/2014 Nissan GT-R at the Sugo circuit today. The new version offers greater mid-range response from the engine, improved acceleration at higher revs, a lowered center of gravity, and greater stability at higher speeds. Nissan says the changes have been employed following lessons learned from the firm’s outing at the Nürburgring 24-hour race.

The result is a zero to 100km/h time of 2.7 seconds – a tenth faster than the current model and a new Nurburgring lap time of 7mins 18secs (down from 7 mins 21secs).

The enhancements to improve responsiveness in the drivetrain and composure in the chassis include a large number of minor upgrades:

Engine

• New high-output injectors more concisely control fuel injection to improve mid-range and high-rpm response.
• A new relief valve for the turbocharger bypass suppresses the rapid decrease of forced injection pressure, again helping to sustain response.
• A new oil pan baffle helps maintain more stable oil pressure and reduces rotational friction especially during high-performance driving.

Chassis

• After measuring the roll centre of the GT-R when cornering and taking deflection of the bushes and tyres into account, engineers have updated the suspension set-up with revisions to the dampers, springs and front anti-roll bar to lower the centre of gravity.
• New cam bolts have been installed on the front suspension to improve camber accuracy and stability when cornering.
• The torque carrying capacity of the driveshafts to the hub bearings has been increased to improve reliability in high-stress situations, such as track driving.

Body

• Reinforcements have been added to the dash panel bar and instrument panel member resulting in increased body rigidity and better suspension control.
