Logitech has just announced the all-new Driving Force GT wheel for Gran Turismo 5 Prologue! This is the first wheel of its kind that has a dial on the wheel itself to allow the user to adjust things on the car in real time, such as brake bias and damper settings. The force-feedback feature has also been given more power, and most importantly, the illuminated GT logo in the center can now be pressed to blow the car’s horn in the game.
