2013 Nissan GT-R: Elevated Performance
LONDON – Nov 2, 2012: Improved response, better stability and
sharper handling – those are the highlights of the 2013 model year
On sale next spring, the four-wheel drive supercar has received a round
of enhancements aimed at subtly boosting the responsiveness of its 550PS
3.8-litre twin-turbocharged V6 engine while improving ride and handling at
the same time.
Applying lessons learned from this year’s Nürburgring 24-Hour race
to the roadgoing GT-R, engineers have improved response in both the mid-
and upper-rpm rev ranges, increased body rigidity and made changes to the
dampers, springs and front anti-roll bar.
As a result, the GT-R is more responsive, has better high-speed
stability and a more refined ride.
Nissan will reveal full prices and exact performance details closer to
the car’s launch, but in the meantime the technical changes are
EngineNew 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.
BodyReinforcements have been added to the dash panel bar
and instrument panel member resulting in increased body rigidity and better
