The 2007 GT-R Nissan's super-sports car is a rare challenge to European and American automakers by a Japanese company more used to family friendly offerings like the Altima sedan.The GT-R requires special attention because its technology is so advanced.
HISTORY
Between 1969 and 1974, and again between 1989 and 2002, Nissan produced a high performance version of its Skyline range called the Nissan Skyline GT-R. This car proved to be iconic for Nissan and achieved much fame and success on road and track. The Nissan GT-R, although no longer carrying the "Skyline" badge, has heritage in the Nissan Skyline GT-R. Like the Skyline GT-Rs R32 through R34, the Nissan GT-R is all-wheel drive with a twin-turbo 6 cylinder engine; however, the evolutionary, incremental changes between Skyline models R32 through R34 have been done away with.
The four-wheel-steering HICAS system has been removed, and the former straight-6 RB26DETT engine has been replaced with a new V6 VR38DETT. Because of the GT-R's heritage, the chassis code for the all-new version has been called CBA-R35, or 'R35' for short, carrying on the naming trend from previous Skyline GT-R generations. The GT-R has also retained its Skyline predecessor's nickname Godzilla The Nissan GT-R’s unique characteristics are instilled not just in the vehicle’s design, but also through a specialized production process. Carbon fiber, aluminum and steel components are assembled with a special high-precision process, which includes a series of vibration tests. Engines and transmissions are assembled by a single craftsman in a “clean room” environment and upon completion, every GT-R undergoes a battery of comprehensive tests to ensure the proper operation of all vehicle components.
Packaging and Driveline Suited for a Supercar
The all-new Nissan GT-R uses a Premium Midship package, an all-new, more advanced version Front Midship (FM) package utilized on other Nissan vehicles. This new package enables the use of the world’s first application of an independent transaxle 4WD system. The transaxle’s layout places the dual-clutch transmission, transfer case and final drive at the rear of the vehicle (instead of the usual front location), which enables vehicle weight to be evenly distributed throughout the car. This gives the Nissan GT-R a superb front-to-rear weight balance, while enhancing leg and foot space and allowing for an optimal pedal layout.
Under the hood, the Nissan GT-R features an all-new 3.8-litre twin turbo V6 “VR38” engine, featuring plasma-sprayed bores and a special twin-turbo exhaust manifold system. A secondary air management system enables the newly designed powerplant to provide approximately 40kg/m of torque during ordinary low-rev driving, which gives an optimum air-fuel ratio for around-town efficiency and helps the Nissan GT-R meet ultra-low emission vehicle (U-LEV) standards in Japan.
High-Performance Safety and Environmental Technologies
The Nissan GT-R offers a long list of safety and environmental features, including, for enhanced visibility inside and out of the vehicle, high-mounted LED stoplamps, bright LED rear combination taillights, “super wide beam” headlights, heated door mirrors and flat-blade wipers.
Standard safety equipment includes a pop-up engine hood system for enhanced pedestrian safety, driver and front passenger SRS Air Bag System, ELR front seat belts with tension reducer, front seat belts with load limiter, and three-point ELR rear seat belts. Driver and front passenger SRS Side Air Bag System and SRS Curtain Air Bag System are offered as options.
Environmental technologies include extensive work to create an U-LEV certification in Japan for the 3.8-liter twin turbo engine and reduced levels of volatile organic compound for materials used in the car.
Functional Design – High Performance Aerodynamics and Style
The Nissan GT-R’s styling 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 suggesting GT-R’s “supercar” level of performance. Utilizing advanced aerodynamics, the Nissan GT-R’s aggressive styling evokes the lines of a well-trained athlete, combining strong character lines with smooth and solid areas.
The all-new GT-R’s body is created with a combination of steel, carbon fiber and aluminum, providing a unique combination of stiffness and lightness. The Nissan GT-R features a low coefficient of drag of 0.27, with high front and rear downforce, which provides the GT-R with enhanced grip in all weather situations, while also enhancing fuel efficiency.
The Nissan GT-R’s large, four-passenger cabin features a sloping “aero blade canopy” roofline and 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 GT-R’s hallmark four-ring taillights, efficient rear spoiler and large, integrated φ120 exhaust tips, provides the signature rear view of the GT-R, as well as optimizing airflow along the top and under the vehicle.
The high level of advanced technology is evident even in the Nissan GT-R’s paint – which utilizes a “double clear coat” and “anti-chipping” process. The Nissan GT-R features Ultimate Silver as a special new color, which is painstakingly hand-polished by craftsman.
An Interior Suitable for Daily Driving or Supercar Duties
Key to the Nissan GT-R’s usability as a both daily driver and a high-performance supercar is its interior, which is designed to balance functionality, a sense of ease, and comfort.
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 doors to give an extra level of comfort and safety.
The instrument panel surrounds the driver, with all meters and multi-function meter at a uniform height to minimize the driver’s head movement when traveling at high speeds. 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.
Functional style is also evident in the Nissan 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 the GT-R. A large, metallic-framed center console features the ergonomically designed shift lever and a red “engine start” button.
Adjustability is central to the daily-driver nature of the Nissan GT-R, with a special “set-up switch” located in the center of the instrument panel. This switch enables the driver to adjust transmission shifts, shock absorbers and the Vehicle Dynamic Control (VDC-R) in three settings – Normal, Comfort or R, the high-performance setting designed for the Nissan GT-R “supercar” application.
A high-speed, high-capacity CARWINGS (Japan market) navigation system, with a powerful 30GB hard disk drive, features an easy-to-use touch pad, as well as traditional navigation switches. The screen interface features not only the navigation system, but also an enriched entertainment system with a Music Box hard drive, DVD and CD player, and Bluetooth® *2 audio function.
For special use in the GT-R application, the multi-function meter also includes mechanical and driving information for safe high performance driving, including acceleration opening, brake pedal pressure, and steering angle. It also includes an “optimal gearshift map,” to emphasize economical vehicle operation.
A specially designed BOSE sound system includes two forward-facing woofers in the rear center armrest area combined with traditional door speakers. All speakers are mounted in rigid aluminum die cast panels, which combined with the design of the system itself, provide sound quality suitable for a supercar.
