Nissan has launched the new GTR-2012. The machine is fully loaded with maximum horse power, riding comfort, the new TRACK PACK option and almost every thing that a race enthusiast has in his wish list.
The 2012 model year GT-R has improved maximum engine output and fuel efficiency (thereby reducing CO2 emissions) by enhancing the car’s engine efficiency. The 2012 MY model comes equipped with asymmetric suspension, multi-performance speed, and highly responsive driving performance which provide a stable, high-quality driving experience for passengers. Additionally, the custom option, ”For TRACK PACK”, inherits the driving DNA of the Spec V model to provide an alternative, more Spartan driving option for potential customers.
2012 Nissan GT-R Overview
1. Mechanical Features
Engine
By improving the GT-R’s engine efficiency, its fuel economy has been raised to 8.6km/L (tested under Japan’s 10-15 mode) or 8.7km/L (in JC08 mode), while engine output has been significantly improved to 404kW (550ps)/6,400rpm with maximum torque of 632N・m(64.5kgf・m) from 3,200 to 5,800 rpm. Engine response and torque at mid- and low-speeds, and power at high revolutions, has been significantly improved, mainly due to:
- Improved intake efficiency - Air flow resistance has been reduced by adding an intake manifold fitted to the head of each unit and the use of resin in the enlarged air intake duct for the intercooler, and
- Improved exhaust emissions efficiency and enhanced control - Air flow resistance has been reduced through a more compact underfloor catalyzer which improves emissions efficiency and reduces weight. For improved exhaust valve cooling performance, a newly-designed metallic sodium-filled valve has been adopted. Valve control timing, the air mixture ratio and ignition timing have been improved as well.
2.Transmission
- Shift feel and quietness have been refined through a strengthened design of the shift fork arm and a firmer fixing bearing for the flywheel housing.
- A high-performance differential oil R35 COMPETITION type 2189E (75W140), which has been used in motorsports, is now provided as a standard feature for every grade.
3.Body
- By reinforcing areas mainly around the rear part of the engine compartment and dash panel, together with increased engine output, more responsive handling and a greater sense of the vehicle’s grip on the road are transmitted to the driver.
- More precise production methods, accompanied by advancements made in the vehicle body, have improved the inter-vehicle detection capability. This was achieved by changes in the positioning of the sensor and more rigid, highly-damped vehicle body, and by adding a more accurate acceleration sensor in areas with higher sensitivity in the vibration testing of each vehicle body.
4.Suspension and brakes
- Considering the added weight of the driver on the right side in a right-hand drive vehicle and that the propeller shaft for front wheels is located on the right side of the vehicle, the GT-R’s suspension has been set asymmetrically for the left and right sides. For the front suspension, a harder spring rate on the left side has been set. For the rear, the suspension arm has been installed upward on the left side and downward on the right for an imbalanced wheel load when the car is stationary, but is equalized during driving, providing improved responsiveness and smoothness which the driver feels when steering, as well as enhanced cornering stability and riding comfort.
-NCCB (Nissan Carbon Ceramic Brakes) are available as a factory-installed option for the GT-R Premium Edition and EGOIST grade. These brakes accentuate the car’s agile road hold and supple ride feel through a dramatically-reduced spring weight and refined, sharp braking performance unique to carbon ceramics. (In addition, service parts prices for the rotors and pads have been reduced.)
