Not exactly. The 2010 Nissan GT-R (2009 in Japan) will have increased horsepower in the engine, and an improved software for the gearbox. As the changes to transmission usually lead to better performance numbers, Nissan engineers at the Tochigi Assembly plant put the new 2010 GT-R on a test at their own track.
The test-engineers were surprised. Despite the lack of launch control, they were able to hit 60 mph in the new and standard 2010 GT-R in 3.3 seconds! That's truly astonishing. This number is to people who used to say that the GT-R was fast only beacause of the launch control. Well, Nissan have smashed these sayings about the GT-R by being even faster without the launch control computer.
Nissan has not made it official yet, but it is expected that the official announcement should come out soon. So, is it true? We surely hope so!
