The game includes a Driving School (License Tests) as well as early version of some circuits, like the New York track which was modified in the full version. A new "Gran Turismo" official steering wheel, the Driving Force Pro known as GT Force Pro in Japan and supporting force feedback, was released by Logitech (Logicool in Japan) to coincide with the "Gran Turismo 4 Prologue" launch date. The European version came with several extra cars, most of them cars unveiled at the 2004 Geneva Motor Show, such as the BMW Concept M5 and the aforementioned Toyota MTRC.
