2012 Nissan GT-R Overview The 2012 Nissan GT-R continues as a multi-dimensional performance machine that lives up to the concept of “the ultimate supercar that can be driven by anyone, anytime, anywhere.” Its Premium Midship platform was created expressly for use with the GT-R. The Premium Midship platform enables the use of a world’s first independent rear trans-axle ATTESA E-TS all-wheel drive system, which optimizes weight distribution and handling capability. This layout places the transmission, transfer case and final drive at the rear of the vehicle, without the use of traditional torque tubes, allowing the suspension to operate independently and optimizing tire grip at each corner. Under the hood, the Nissan GT-R again features its advanced VR38DETT 3.8-liter twin turbo V6, now producing 530 horsepower at 6,400 rpm and 448 lb-ft of torque from 3,200 to 6,000 rpm, while meeting ultra-low emission vehicle (ULEV) standards. The engine features innovative plasma-sprayed bores replacing cast iron liners for reduced friction, lighter weight, enhanced cooling, power output and fuel efficiency; a symmetrical independent intake and exhaust manifold system featuring twin high-performance IHI turbochargers; a secondary air management system for improved cold-start emissions performance; a thermostatically controlled oil-cooling system; an oil scavenger pump to maintain oil flowing to the turbochargers; and a lateral wet and dry sump oiling system. All GT-R engines are hand-assembled in a clean room environment at the Nissan Yokohama engine plant. The VR38DETT is backed by an advanced paddle-shifted sequential 6-speed dual clutch transmission, which can be driver selected to shift at race car-like speeds. The sequential-shifting transaxle features separate wet clutches for the odd (1,3,5) and even (2,4,6) gears and pre-selects the next highest and next lowest gear for immediate shifts. It also features Hill Start Assist for easy starts on uphill inclines. Contributing to overall vehicle balance and low center of gravity, the unique offset input and reaction shaft design of the rear trans-axle enables a shorter design profile versus a typical manual transmission, moving the concentration of powertrain weight lower in the vehicle. Putting the power to the ground is an electronically controlled ATTESA E-TS all-wheel-drive system specifically developed for GT-R. The rear drive-biased system can vary torque split from 0:100 to 50:50 depending on speed, lateral acceleration, steering angles, tire slip, road surface and yaw rate. Of note is a special GT-R-specific yaw-rate feedback control, which measures the differences between the target yaw rate calculated from steering angle and actual yaw rate detected by the yaw-rate sensor and G sensor to adjust torque bias. GT-R’s handling duties are managed by a sophisticated 4-wheel independent suspension system mounted to high-precision six-point front and rear sub-frames. The front suspension geometry has also been modified for 2012 to provide more balanced handling. A special Bilstein DampTronic driver adjustable shock absorber system utilizes multiple vehicle information systems to provide appropriate damping forces and high level of control for a variety of driving situations. The DampTronic system features three driver selectable settings – Normal; Comfort, for maximum suspension compliance; or “R,” for ultimate handling. The same three-stage adjustability is also available for the VDC system and transmission shift operation. Stopping power is again provided by Brembo® monoblock six-piston front and four-piston rear calipers with enlarged 15.4-inch front (verses the previous 15.0) and 15.0-inch rear Brembo full-floating cross-drilled two-piece rotors and low-steel high-stiffness brake pads that minimize fade and provide intense stopping performance. The calipers utilize race car-style radial mounting to minimize caliper flex during extreme braking. GT-R-specific lightweight forged 20-inch wheels, with special knurling to assist with securing the tires during hard acceleration or braking, are wrapped with new Dunlop® SP Sport Maxx GT 600 DSST CTT ultra high performance run-flat tires filled with nitrogen, sized 255/40ZRF20 front and 285/35ZRF20 rear. Optional Dunlop® SP 7010 all-season run-flat tires are offered as part of the Cold Weather Package.
