The Nissan Skyline GT-R


Nissan Skyline GT-R

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[6][7] 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.[8] Because of the GT-R’s heritage, the chassis code for the all-new version has been called CBA-R35,[9] 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.[10][11]

GT-R Prototype at the 2005 Tokyo Motor Show

Two concept vehicles were displayed at motor shows prior to the unveiling of the production model. The first concept was shown at the Tokyo Motor Show in 2001 to preview what a 21st century GT-R would look like.[12] At the 2005 Tokyo Motor Show, Nissan unveiled a redesigned concept, the GT-R Proto, stating that the production GT-R would be 80-90% based on this concept.[13]

[edit] Production model

The production version of the GT-R debuted at the 2007 Tokyo Motor Show, launching in the Japanese market on December 6, 2007. The U.S. official launch was 7 months later on July 7, 2008. Universal Nissan in Los Angeles provided a customer with the delivery of a new GT-R, fresh from the production line at 12:01 a.m., on July 7, 2008. The Canadian launch was also in July 2008. Europe became the third consumer market, where it launched in March 2009. The large disparity in initial marketing between these regional releases is due to Nissan having to build GT-R performance centers where the car is serviced. Also the engine and rear-mounted dual-clutch gearbox are built by hand, thus limiting production to around 1000 cars a month.[14]
[edit] Specifications
The VR38DETT engine

The Nissan GT-R is powered by the VR38DETT engine, a 3,799 cc (3.8 L; 231.8 cu in) DOHC V6. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction.[15] Production vehicles produce a manufacturer-claimed engine output of 474 bhp (353 kW) at 6400 rpm and 434 lb·ft (588 N·m) at 3200-5200 rpm.[16] According to independent dynamometer tests, the GT-R produces 416 hp (310 kW) to 475 hp (354 kW) and 414 lb·ft (561 N·m) to 457 lb·ft (620 N·m) at the wheels.[17][18] The engine also meets California Air Resources Board Ultra Low Emission Vehicle (ULEV) standards.[19] 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 welded steel chassis with aluminum used for the hood, trunk, and doors.[20] A rear mounted six-speed BorgWarner dual clutch semi-automatic transmission 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) aids in stability. Three shift modes can also be selected for various conditions. The GT-R has a drag coefficient of 0.27.[21]
