In the game, the car features a gas turbine engine, but in the flesh it 'only' gets a twin-turbo V6 producing 1106kW of power. It's also said to be the pinnacle car, the fastest car in the game. We'll have to wait and see this thing on the track to see if reality measured up to the virtual world though.
A release date for the game is apparently set for just after Christmas, with Gran Turismo 5 creator recently saying the discs are been stamped as we speak... but when the game actually goes on sale is anyone's guess.
