The Nissan GTR is a 2+2 high performance car unveiled in 2007. The GTR is know as the Godzilla. This refers to the low price for the car (and a lot of power) in reference to the other high performance cars in this sector. Over the time Godzilla has been modernised and is now in the 4th generation. If you are one of the costumers that want even more power you can purchase one of the Nismo models. These cars are more track focused, have a bunch of more hp and are of course more expensive. So it is up to your preferences and your wallet.
The car is powered by a twin-turbo V6 engine. In the latest version it has 570hp and a topspeed of around 315km/h (196 mph).
