The GT-R emblem at the center 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.
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.
The Black Edition adds custom red-trimmed Recaro
seats, red and black interior trim and a dark headliner.
Engine and Transmission Enhancements
By modifying the boost pressure of the Nissan GT-R's 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 by about 4%.
At the same time, the engine output is significantly improved to 530 hp at 6,400
rpm with maximum torque of 488 lb-ft from 3,200 to 6,000 rpm.
Cleaner
emissions are realized 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 on the 2012 Nissan GT-R, which optimizes 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 22
lbs 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. This occurs when Nissan GT-R's speed is below
6 mph and the steering wheel is turned more than halfway.
Body
Strengthening
A highly rigid, lightweight strut supporting bar, made
of carbon composite with aluminum 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 GT-R 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 utilized 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 stabilizer bar is modified
to improve the vertical load response of the tires. Front caster angle is
increased from 5°35 to 6°00 to improve tire road holding ability when turning
and stability while driving straight.
For the rear suspension, toe
performance is modified by changing the roll center height to a lower position
in order to improve tire grip while making turns and to better communicate
driving feel.
On the 2012 GT-R, an aluminum 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 390mm)
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 Tires
The 2012 Nissan GT-R also
features newly designed, lighter weight and more rigid forged aluminum-alloy
wheels. Made by Rays, the wheels help improve tire responsiveness to vertical
load. Knurling inside the wheel is modified to avoid deviation of tire rotation
direction caused by the higher engine output. On the wheel surface, a new Hyper
Blue Black Chrome color is adopted, which expresses high quality and
high-performance feel. The wheels' deep gloss is created by utilization of a
five-layer coating process.
The Dunlop SP SPORT MAXX GT 600 DSST CTT
tires have a new compound to improve tire grip. With renewed structure and
improved tread and sidewall rigidity, straight-line stability in rutted roads is
enhanced.
