Considered by many to be the perfect "street-able" supercar at its launch, the team behind the creation of the Nissan GT-R has never slowed down. The relentless ongoing development of the GT-R has been driven by the fact that the GT-R competes in a rarified supercar segment against vehicles costing more than twice as much – and where bragging rights can be won or lost by mere fractions of a second. The new 2015 Nissan GT-R continues the tradition by taking another step forward in the effort to deliver passion and emotion to customers through "extreme development."

2015 Nissan GT-R: The Development Continues
Following a major change to GT-R's renowned engine in 2012 – including improved intake efficiency, reduced airflow resistance, improved exhaust emissions efficiency and a 15-horsepower increase to 545 hp (along with a 15 lb-ft increase in torque to 463 lb-ft) – the development of the engine continues for the 2015 model year.

Fuel injectors are adopted for enhanced torque response in the 4,500 – 6,000 rpm range, improving throttle and acceleration feel at mid- and high-rpm ranges. Also, an oil pan baffle has been added to stabilize oil behavior and oil pressure under high performance driving conditions. The baffle reduces rotational friction, which contributes to the increased responsiveness. As in previous years, each engine is hand-assembled from beginning to end in a special clean room by a single specially trained technician, a process similar to racing powerplant construction. An aluminum nameplate is added to each engine showing the name of the engine constructor.

The GT-R's advanced VR38DETT 3.8-litre twin turbo V6 engine again features innovative plasma-sprayed bores (versus 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 estimated (5-cycle MY15 figures have not yet been released) at 14.3 L/100kms (20 mpg) City and 10.5L/100kms (27 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 quick shifts. It also features Hill Start Assist for easy starts on uphill inclines.  High performance differential oil, used in GT-R motorsports competition, is standard.

The Nissan GT-R's unique Premium Midship platform, created expressly for use with the GT-R, 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.

Outstanding Performance Meets a New Level of Sophistication
The 2015 GT-R's multi-dimensional performance means drivers can enjoy the full depth of the vehicle's capabilities whether navigating corners of a winding mountain road, cruising at highway speeds or in an urban environment. Chassis enhancements for the new model year are balanced between the suspension, steering and braking systems and tire design.

While chassis development has been ongoing since the GT-R's introduction – including significant on-track and endurance competition testing at Germany's famed Nurburgring – for 2015 the sophisticated 4-wheel independent suspension has been fine-tuned to reduce load fluctuation between the four wheels, giving better road handling and more consistent grip.

For 2015, more consistent tire contact has been achieved by optimizing control of the shock absorber valves, as well as use of modified front stabilizer spring rates and updated bush links. The tuning of these parts helps enhance road holding capability, resulting in a poised, confident ride and outstanding traction on rough roads. The reduction in minute vibrations and road noise helps provide a more relaxing, comfortable ride. An additional benefit is improved straight-line stability, with fewer small steering corrections needed to maintain trajectory during highway driving.

Every 2015 GT-R features a special Bilstein® DampTronic driver adjustable shock absorber system that 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. The same three-stage adjustability is also available for the VDC system and transmission shift operation.

The GT-R's steering has been fine-tuned to reduce the effort for in-town maneuvers, while maintaining GT-R's exceptional feedback during highway driving. The steering system is a vehicle speed-sensitive power rack-and-pinion design with aluminum steering rack, four-point mounting and stiff insulators.

For 2015, braking calibration has been retuned for firmer, more linear response at everyday speeds, making smooth braking more intuitive – generating a sense of greater confidence, particularly in wet conditions. Stopping power is 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 GT-R's rigid forged aluminum 20-inch wheels, manufactured by RAYS®, feature knurling inside the wheels to help 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® forged lightweight wheels in place of the Premium model's 10-spoke design.

The tires are Dunlop® SP Sport Maxx GT 600 DSST CTT ultra high performance run-flat nitrogen-filled tires, featuring a new compound and revised tread pattern, designed to match the suspension characteristics. As such, the tire design has been modified for use with the 2015 GT-R with stiffer sidewalls to reduce deformation, improving steering response under hard cornering. Standard tire sizes are 255/40ZRF20 front and 285/35ZRF20 rear.

Nissan has also enhanced the level of precision-constructed body elements and advanced assembly methods to help achieve the 2015 GT-R's exceptional balance of high-speed handling and ride comfort. And thanks to optimized insulation and acoustic tuning, even at high speeds the occupants are able to enjoy the sport engine sound.

Toward that end, "engine boom" has been reduced through use of the standard Bose® Active Noise Cancelation system. Additional sound deadening, including application of additional noise insulation under the floor and trunk, in the drive tunnel and on the firewall, helps control both engine and road noise.

Each body part is made of materials selected for optimum performance – starting with the precision-constructed multi-material hybrid body. A combination of steel, carbon fiber and die-cast aluminum are used to realize high stiffness and light weight.

For 2015, the Black Edition features a special dry carbon fiber material** rear spoiler that is also incredibly strong and contributes to increased aerodynamic downforce. Handmade in a limited monthly production run, a special coating allows the carbon fiber "weave" to be felt by the touch.

"The performance enhancements for 2015 signal Nissan's intent to keep the GT-R on the leading edge of international sports car design, technology and performance year after year after year," said Rhind.

Functional, High Performance Aerodynamics and Style
The Nissan GT-R's dramatic styling is unchanged for 2015. Every aspect, from the overall design to the smallest details, is created to maximize the vehicle's driving experience – as well as to suggest GT-R's supercar level of performance.

The GT-R's hybrid body construction is again a combination of steel, carbon fiber and die-cast aluminum, providing a unique combination of stiffness, precision and lightness.  

The body features a low coefficient of drag of 0.26, achieving high front and rear downforce. GT-R's front fenders express power and stability, while the "aero-blades" on the fenders' edges provide optimum airflow around the tires and along the body. The vents in the fenders' trailing edges assist in providing front downforce and optimizing side airflow. The aggressive front end, with a large hood bulge and enlarged central air intake, provide a sophisticated style as well as undisturbed airflow for power and cooling. The "super wide beam" headlights feature three additional sub-reflectors (compared to conventional lights) to give a wide illumination spread.

The Nissan GT-R's four-passenger cabin features a sloping "aero blade canopy" roofline and a curved C-pillar "sword edge," which expresses the distinctive GT-R identity, as well as facilitating air flow around the rear of the vehicle. The signature rear view of the GT-R is provided by its hallmark four-ring taillights, while air flow above and below the vehicle is managed by the functional rear carbon fiber underbody diffuser, rear venting, rear spoiler and large, integrated quad exhaust tips.

The GT-R Black Edition's unique rear spoiler is designed to be as slippery to the wind as it is attractive to the eyes. Handmade in a limited monthly production run, a special coating allows carbon fiber "weave" to be felt by the touch. The lightweight dry carbon fiber material* is also incredibly strong, contributing to increased aerodynamic downforce.

GT-R's advanced technology is present even in the vehicle's paint, which utilizes a durable anti-chip paint and "double clear coat" process. The 2015 GT-R adds a new exterior body color with special finishing – Regal Red, which features a blend of 24 18 karat gold-coated glass flakes blended into the paint. The 2015 color palette also includes Deep Blue Pearl, Jet Black, Solid Red, Gun Metallic, Pearl White and a limited production 4-stage metallic Super Silver. As expected, GT-R's advanced technology is present even in the vehicle's paint, which utilizes a durable anti-chip paint and "double clear coat" process.

A New Premium Interior for 2015
Just as GT-R reflects a constant pursuit of performance improvements, driver and passenger needs and desires are also continuously reviewed. Takumi, the Japanese word for artisan, has always been reflected in the GT-R, which features a great amount of hand craftsmanship.  The Premium model interior features a change in colour and stitching for a higher quality look and feel.

In addition, the Black Edition model's steering wheel features coordinated red accents, providing a sportier appearance.  The biggest interior change for 2015 is availability of a new optional Premium Interior Package with exclusive Ivory colour semi-aniline leather appointments with hand-stitching on the front seats, along with Ivory accents on the instrument panel, steering wheel, door trim, armrests and shift knob.

"Comfort and a sense of luxury refinement are never out of place, even in car with the ultra performance levels of GT-R," said Rhind. "The Premium Interior Package, which will be available in limited numbers, adds a great new look and really accents the high levels of craftsmanship found throughout each and every GT-R."

As in previous years, the key to the Nissan GT-R's usability as both a daily driver and a high-performance machine is its balance of functionality and comfort. It provides comfortable four-passenger seating and trunk capacity of two golf bags or suitcases. Sculpted performance bucket seats give the driver and passenger a comfortable driving experience, and soft pads are utilized on the dash in front of the passenger and both doors to give an extra level of comfort. The rear transaxle layout of GT-R, with a flat floor and narrow center tunnel, allows GT-R to have an optimal driving position.  The GT-R Black Edition adds a unique red and black interior colour treatment and Recaro® leather-appointed seats.

The GT-R's cockpit-style instrument panel surrounds the driver, with all meters and multi-function meter at a uniform height to minimize the driver's head movement. A large center-mounted tachometer, with gear display on its upper right, as well as the easy-to-read graphics of the display, gives the driver instant detailed information, essential for the performance nature of the GT-R. Each meter features a dial plate design that evokes the idea of engaged gears, as well as a three-dimensional metal-like ring, suggesting the multi-dimensional performance of GT-R. A large, metallic-framed center console features an ergonomically designed shift lever and a red "engine start" button. Carbon fiber interior trim is offered for all models.

The centerpiece of the instrument panel is a video game-inspired multi-function display that was created in collaboration with Polyphony Digital, makers of the Gran Turismo electronic game. Eleven pages of information are available on this system, including mechanical and driving information, acceleration, brake pedal pressure, steering angle and a recording function with playback.

Additional on-screen information includes a Navigation system and Bluetooth® Hands-free Phone System. The navigation system includes NavTraffic Real-Time Traffic Information and NavWeather capabilities (SiriusXM subscription required, sold separately).

All 2015 GT-R models again include a specially designed 11-speaker Bose® audio system, featuring Active Noise Cancellation and two forward-facing woofers in the rear center armrest area. Rigid aluminum die cast panel-mounting of all speakers allowed Bose® engineers to perfect the acoustical performance of the GT-R sound system. Streaming Audio via Bluetooth® is standard.

Standard safety equipment includes a Nissan Advanced Air Bag System for driver and front passenger, front seat-mounted side-impact supplemental air bags for driver and front-passenger and standard roof-mounted curtain side-impact supplemental air bags for front seat occupant head protection – along with front seat belts with pretensioners and load limiters and three-point ELR/ALR rear seat belts.
