9/10 Nissan GT-R

Concept 

The Nissan GT-R is a sports car produced by Nissan, released in Japan on December 6, 2007, the United States on July 4, 2008, and the rest of the world in March 2009. 

The Nissan GT-R is powered by the VR38DETT engine, a 3,799 cc (3.8 L; 231.8 cu in) DOHC V6 with plasma trasferred wire arc sprayed bores.Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Production vehicles produce a manufacturer-claimed engine output of 485 bhp (362 kW) at 6400 rpm and 434 lb·ft (588 N·m) at 3200-5200 rpm. The engine also meets California Air Resources Board Ultra Low Emission Vehicle (ULEV) standards. A curb weight of 1,730 kg (3,800 lb) or 1,736 kg (3,830 lb) with side curtain airbags is achieved using a jig weldedsteel chassis with aluminum used for the hood, trunk, and doors. A rear mounted six-speed BorgWarner designed dual clutch semi-automatic transmission built by Aichi Machine Industry is used in conjunction with the ATTESA E-TS system to provide power to all four wheels and along with Nissan's Vehicle Dynamics Control (VDC-R) to aid in stability. Three shift modes can also be selected for various conditions

Design

Nissan chief creative officer, Shirō Nakamura, has likened the new GT-R to the eponymous giant robots of the Gundam series. Nakamura stated: "The GT-R is unique because it is not simply a copy of a European-designed supercar; it had to really reflect Japanese culture."

Nakamura noted that the GT-R's square lines and vents were influenced by Gundam robots. Nissan's American designers sculpted the rear three quarters of the vehicle, while their European designers sculpted the roofline.

Polyphony Digital, creators of the Gran Turismo series of racing video games, were themselves involved in the development of the GT-R, having been contracted to design the GT-R's multifunction display

Nissan introduced the GT-R SpecV on January 7, 2009 at the 2009 Tokyo Auto Salon. Exterior changes from the base GT-R consist of a carbon fiber rear spoiler, grille, and brake ducts, along with an exclusive Ultimate Black Opal paint job. Interior changes include a set of carbon fiber Recaro front seats with the rear seats being completely removed. Carbon fiber covers the center storage box, instrument panel, and replaces the majority of the interior trim.

The GT-R SpecV is powered by the standard twin-turbo 3,799 cc (3.8 L; 231.8 cu in) V6 with no increase in horsepower. A new high gear boost controller that allows a temporary increase in boost pressure to the IHI twin turbochargers, now larger than those on the standard GT-R, should deliver more torque in mid to high-range revs. Other mechanical changes include a titanium exhaust, reworked suspension, carbon ceramic brakes, and 20-inch (510 mm) NISMO wheels. Overall weight is decreased by 132 lb (60 kg) over the standard GT-R.

Japan sales began on February 2, 2009 at seven pre-selected dealers who are staffed by mechanics with special GT-R SpecV training and are knowledgeable of racing circuit driving. Pricing is set at ¥15,750,000 (over US$160,000). Nissan has yet to announce any plans to sell the Spec V in the USA.

In Auto Express testing the SpecV posted a 0-60 mph time of 3.2 seconds, pulled 1.12 g on the skidpad and 74.7 mph in the slalom. An earlier tested Corvette ZR1 resulted in an identical slalom speed but a lower 1.06 g on the skidpad.

Interior Design 

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.
