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.
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).[23] 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. 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.
