2013 Nissan GT-R Overview

2012.02.24  –  As one of the most acclaimed supercars in automotive history, the Nissan GT-R is the ultimate expression of the Nissan brand and its “Innovation for All” philosophy.  A multi-dimensional performance machine that lives up to the concept of “the ultimate supercar that can be driven by anyone, anytime, anywhere,” the Nissan GT-R receives a number of engine and suspension refinements for its fifth year of production – all designed to enhance its already legendary performance.

Enhancements to the 2013 Nissan GT-R signal its intent to remain on the leading edge of international sports car design, technology and performance.  Major refinements to GT-R’s renowned engine for the new model year include improved intake efficiency, reduced airflow resistance including an enlarged air intake duct for the intercooler, and improved exhaust emissions efficiency and enhanced control.  Each engine is hand-assembled in a special clean room, similar to racing powerplant construction.  As a result, horsepower is rated at 545 hp, an increase of 15 hp over the 2012 GT-R’s 530 hp.  Similarly, torque has been increased to 463 lb-ft from 448 lb-ft.

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.  Also, high performance differential oil, used in GT-R motorsports competition, is now standard for production models.

In addition, the suspension has been retuned and a handmade dry carbon rear spoiler has also been added to the Nissan GT-R Black Edition model.  Other 2013 enhancements include the addition of a new blue lighting treatment inside the tachometer ring to match the shift position indicator light, helping provide a more sophisticated cockpit atmosphere.  A RearView Monitor is now standard on all models.

More Power and Refinement for 2013

The 2013 Nissan GT-R’s advanced VR38DETT 3.8-liter twin turbo V6 now produces 545 horsepower at 6,400 rpm (versus the previous 530 hp) and 463 lb-ft of torque at 3,200 – 5,800 rpm (versus the previous 448 lb-ft), while still 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.  Fuel economy is rated at  16 mpg City and 23 mpg Highway.

The VR38DETT V6 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.

The 2013 Nissan GT-R continues to utilize a 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 transaxle ATTESA E-TS all-wheel drive system, which optimizes weight distribution and handling capability.  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.

The Premium Midship Platform 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.

Contributing to overall vehicle balance and low center of gravity, the unique offset input and reaction shaft design of the rear transaxle enables a shorter design profile versus a typical manual transmission, moving the concentration of powertrain weight lower in the vehicle.

The 2013 GT-R’s handling duties are managed by a sophisticated 4-wheel independent suspension system mounted to high-precision six-point front and rear subframes.  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 15.35-inch front 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.

The 2013 Nissan GT-R’s rigid forged aluminum 20-inch wheels, once again manufactured by RAYS®, help improve suspension response.  Knurling inside the wheels helps keep the tires from slipping around the wheels under heavy acceleration or braking.  The wheels feature a premium dark (near black) finish, which provides a high quality, high-performance look.  The Black Edition features special metallic black six-spoke RAYS® lightweight wheels in place of the Premium model’s 10-spoke design.  The wheels are wrapped with 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.

Functional, High Performance Aerodynamics and Style

The Nissan GT-R’s dramatic styling, refreshed for the 2012 model year with a redesigned front fascia and integrated high intensity LED running lights, follows the “function over form” theory.  Every styling aspect, from the overall design to the smallest details, is created to maximize the vehicle’s driving experience – as well as suggest GT-R’s “supercar” level of performance.

The GT-R’s hybrid body construction is created with a combination of steel, carbon fiber and die-cast aluminum, providing a unique combination of stiffness, precision and lightness.  The body features a lowered coefficient of drag of 0.26, achieving high front and rear downforce, providing stability and handling performance in a wide range of driving conditions.
