I'll focus on the part that says,
"GT Academy builds on the long-standing partnership between PlayStation and Nissan that began with
Nissan working with Gran Turismo developers Polyphony Digital. Nissan provided vehicles, racing drivers and feedback to help perfect the games ultra-realistic driving simulation.
Roles were reversed in 2007 when Nissan called upon Polyphony Digital to design the interface for the onboard computer for the GT-R, Nissans new supercar. The multifunction meter provides drivers with updates on the cars performance and systems a collaboration recognised as a motoring industry first. In the latest game, Gran Turismo 5 Prologue on PLAYSTATION®3 (PS3), Nissans GT-R joins a garage filled with 71 dream cars including seven other top Nissan sports cars"
