As the fourth installment of the worldwide blockbuster-selling Gran Turismo series, Gran Turismo 4 is available exclusively for the PlayStation 2 computer entertainment system. Following in the footsteps of the PlayStation 2 "Greatest Hit," Gran Turismo3 A-spec, and a racing franchise that has sold more than 36 million units worldwide, Gran Turismo 4 features authentic racing gameplay that focuses on more than 650 cars, up to 100 courses and unique race modes. With an all-new physics engine and an all-new artificial intelligence engine, combined with revolutionary technology, Gran Turismo 4 delivers enhanced, if not perfected, game physics, graphics, and feel, acting as a near-realistic automotive driving simulator.
