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.

In Gran Turismo 4, the characteristics of the cars are realistically designed and calculated so that they handle to the "real life" physics of that particular vehicle, taking into account weight, speed, friction, wind, and more. Courses include various sites such as Nurburgring Nordschleife, New York City, the Grand Canyon, Tsukuba Circuit, and more. Highly detailed vehicles and environment mapping create broadcast-quality graphics, with light and competitor car reflections on the player's automobile to leaves on a tree shaking in the wind.

1. New physics engine adding a higher level of realism in cars, which allows for cars to be handled easier.
2. More than 5,000 polygons per vehicle capture exceptional detail, right down to the disc brakes behind the wheel.
3. With an all-new AI engine, race opponents posses advanced artificial intelligence, which allows for behavior that captures human-like emotion.
