Nissan GT-R (Premium Edition) - 2007

Marca - Kyosho
Escala - 1:18
 
 
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. 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 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 (VDC-R) to aid in stability. Three shift modes can also be selected for various conditions. The GT-R has a drag coefficient of 0.27.
Nissan claims the GT-R can reach a top speed of 311 km/h (193 mph), Motor Trend recorded a top speed of 195.0 mph (313.8 km/h). It has been tested to achieve 0-60 mph (97 km/h) times as low as 3.2 seconds with "launch control" and 3.8 seconds without  (improved to 3.5 seconds in models produced since March 2009). Nissan's chief vehicle engineer Kazutoshi Mizuno has indicated that he has never used the term "launch control", which refers to the act of turning off vehicle dynamic control (VDC) and launching the car at around 4500 rpm. However, Nissan's director of product planning John Wiener clearly stated in an interview with Jay Leno that "we [Nissan] actually offer a 'launch mode'". The GT-R user's manual states that turning off the VDC is only meant for escaping low-traction situations such as mud or snow, and that damage to the transmission is not covered under warranty if the VDC is used in other ways. It reportedly costs $20,000 USD to replace a damaged transmission outside of warranty.  Nissan has re-programmed the 2010 model year GT-R to reduce the engine speed at launch to around 3,000 to 3,500 rpm with VDC enabled, which is meant to improve acceleration times. The new programming was also installed on old 2009 vehicles still in Nissan's inventory, and is available for existing 2009 vehicles.
