22nd October, 2010
For Model Year 2011, the Nissan GT-R features improved
engine output and torque, greater fuel efficiency, revised handling, a refreshed exterior with improved
aerodynamics, revised interior treatment and new wheels and tyres. The large number of enhancements for
the new model year is part of the continuous advancement of the GT-R design, technology and performance
since its debut in Australia early last year. Nissan has also enhanced the level of after-sales support
for GT-R owners, providing even greater value for customers.
Developed under the theme of offering the “world’s best multi-performance and responsive driving
pleasure,” every area of the Nissan GT-R has been carefully rethought or retuned for MY11. The changes
range from greater body stability and strength and improved aerodynamics performance to a sportier
interior and enhanced performance. Following are the key enhancements of the GT-R design.
Engine and Transmission Enhancements
- By modifying the boost pressure of the turbocharger, valve timing and air mixture ratio, reducing
intake air resistance by enlarging the inlet pipe diameter, and reducing exhaust air resistance through
use of an enlarged section of exhaust pipe, fuel economy is improved to 12.0 litres/100 kms (previously
12.5 litres/100 kms).
- At the same time, the engine output is significantly improved to 390 kW(523 hp)/6,400 rpm with
maximum torque of 612 Nm from 3,200 to 6,000 rpm.
- Cleaner emissions are realised through adopting an ultra-low precious metal catalyst and ECM with
high-capacity microprocessor - achieving SU-LEV certification levels.
- A new SAVE mode is adopted, which optimises driving torque and modifies the shift schedule to
improve actual fuel economy when driving highways or open roads
- Starting performance while selecting “R mode” for the transmission and VDC-R is improved.
- A weight saving of 10 kg has been achieved.
- To control tight corner braking, which can occur when starting the vehicle while turning the
steering wheel, 2WD mode is added to temporarily shift to 2WD driving. Note: When the vehicle speed is
below 10 km/h and the steering wheel is turned more than halfway.
Body Strengthening
A highly rigid, lightweight strut supporting bar, made of carbon composite with aluminium honeycomb
material, is installed in the partition wall of the engine compartment. By linking the right and left
struts to quickly receive suspension input, the vehicle body’s responsiveness to driving operation is
enhanced.
An additional support member is installed in the passenger side of the instrument panel.
Responsiveness of the vehicle body is further improved by enhanced rigidity for connection with the
engine compartment.
For further production accuracy, the fitting precision of the body panels is enhanced and a
higher-precision G sensor is utilised in checking the instrument panel during the vibration testing of
each vehicle body.
Suspension and Braking Modifications
For the front suspension, the lever ratio of the springs, shock absorbers and stabiliser bar is
modified to improve the vertical load response of the tyres. Front caster angle is increased from 5°35
to 6°00 to improve tyre road holding ability when turning and stability while driving straight.
For the rear suspension, toe performance is modified by changing the roll centre height to a lower
position in order to improve tyre grip while making turns and to better communicate driving feel.
An aluminium free-piston shock absorber design is newly developed which generates more precise
damping force to constantly provide stable road holding and a load shift that quickly responds to
driver’s intention. Reduced friction in the shock absorbers provides high quality, smooth ride
comfort.
A thin, large-diameter rotor (now 390 mm) developed uniquely by Nissan is adopted to improve braking
force, fade resistance, pedal control ability and extend brake rotor life for sporty driving.

Wheels and Tyres
The MY11 Nissan GT-R also features newly designed, lighter weight and more rigid forged
aluminium-alloy wheels. Made by Rays, the wheels help improve tyre responsiveness to vertical load.
Knurling inside the wheel is modified to avoid deviation of tyre rotation direction caused by the
higher engine output. On the wheel surface, a new Hyper Blue Black Chrome colour is adopted, which
expresses high quality and high-performance feel. The wheels’ deep gloss is produced by utilisation
of a five-layer coating process.
The Dunlop SP SPORT MAXX GT 600 DSST CTT tyres have a new compound to improve tyre grip. With
renewed structure and improved tread and sidewall rigidity, straight-line stability in rutted
roads is enhanced.
Exterior and aerodynamics
Even with GT-R’s already intense and stable form, its world-leading aerodynamics performance is
further improved through a number of significant enhancements. Downforce is increased by about 10%,
while the coefficient of drag is further reduced from 0.27 to 0.26.
Stability is improved by enlarged bumper and grille openings.
The front bumper is newly designed with double rectifier fins and Hyper Daylight with a
large-diameter reflecting surface and high intensity white-colour LED lights. The design increases
front downforce by about 10%, while also reducing air resistance inside the engine compartment. The
volume of air that passes through the radiator and cools down the front brakes is also increased.
The redesigned rear bumper features a lower centre of gravity than the previous design, made by
a sculptured lower portion and extended length. Underfloor cooling performance is enhanced with air
resistance reduced by extending a rear diffuser.
Cooling performance for the muffler is improved and rear downforce is increased by about 10%
through use of a new rear bumper air outlet, which helps remove air in the rear wheelhouses.
A newly designed tailpipe finisher with enlarged diameter is adopted. Rear high intensity LED
fog lamps are provided as standard equipment to help improve visibility from vehicles behind in
rainy or snowy conditions.
Six exterior colours are available, including two new colours: Jet Black and GT Blue.
Interior
A newly shaped instrument panel pad and navigation system display finisher are adopted, with
stitch lines changed to express an enhanced quality feel.
Real carbon centre cluster finisher is used, along with matt black finished switches.
The GT-R emblem at the centre of the steering wheel has a new velour-like coating, expressing a
glossy texture. For the paddle shift, a coating exposing the magnesium base material is applied.
Chrome-plated rings in the console and air-conditioner outlets are finished with a new black
smoky coating, expressing greater sportiness.
Seats
New seats provide an improved level of comfort and safety while cornering. In addition, fatigue
levels are reduced for the thighs and lower back by changing the shape, extending the length of
seating surface and refurbishing the cushion stroke. A new seatback design seatback is adopted to
improve fit.
