2012 GT-R Features More Power and Updated Design

Source: Nissan | Published: Wed Nov 17, 2010

(continued from the previous page)

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.
