The Nissan GT-R is a sports car produced by Nissan and first released Japan in 2007. It is the successor to the Nissan Skyline GT-R although it is no longer part of the Skyline range.
Between 1969 and 1974, and again between 1989 and 2002, Nissan produced a high performance version of its Skyline sedan 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 later generations of the Skyline GT-Rs, the Nissan GT-R is four-wheel drive with a twin-turbo 6 cylinder engine and has the signature four round tail lights. However, the GT-R is an entirely new model sharing little with its Skyline siblings and is a complete redesign from previous Skylines rather than an incremental evolution; 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,given to it by the Australian motoring publication Wheels in its July 1989 edition.
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. 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.
The Nissan GT-R is powered by the VR38DETT V6 engine, a 3,799 cc DOHC V6 with plasma transferred wire arc sprayed cylinder bores. Two parallel Ishikawajima-Harima Heavy Industries turbochargers provide forced induction.Models manufactured between 2007 and 2010 produce a manufacturer-claimed engine output of 492 PS at 6400 rpm and 434 lb·ft at 3200–5200 rpm.The engine also meets California Air Resources Board Ultra Low Emission Vehicle standards. A curb weight of 1,730 kg or 1,736 kg with side curtain airbags is achieved using a jig welded steel 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 to aid in stability. Three shift modes can also be selected for various conditions. Beginning in 2010, engine power and torque were upgraded to 390 kW at 6400 rpm and 612 N·m at 3200–6000 rpm respectively. Models produced in 2012 again featured improved engine output at at 6400 rpm and 628 N·m at 3200–5800 rpm. In the near future, it is speculated that the GT-R might even be available as a hybrid.
