In Gran Turismo 4 the characteristics of the cars are realistically designed and calculated so that they handle as per the real-life physics of that particular vehicle, taking into account weight, speed, friction, wind and more.

New technology immerses the player in real-life environments such as New York City and the Grand Canyon. Highly detailed vehicles and environment mapping create broadcast-quality graphics, from light and competitor car reflections on the players automobile to leaves on a tree shaking in the wind. In offline gameplay, players will have the opportunity to race in enhanced arcade and simulation modes, experiencing more than 500 authentic automobiles from manufacturers around the world, with a range from vintage to modern vehicles. Courses include existing closed racing circuits to specially designed city courses, reaching a total count of up to 100 tracks. The online mode features a robust system for players to race with up to six other players and interact and chat with others to form an automotive community.

Polyphony Digitals Gran Turismo 4 is one of 2005s biggest releases and, to boot, one of the most important PS2 games yet. What makes it such a significant title First up, Gran Turismo 4 is bigger and better than previous games in the record-breaking series. Much bigger, in fact: there are some 500 cars to drive, and around 100 courses on which to take those motors for a spin. Every single car is a perfectly modelled replica of its real-life equivalent, containing much more detail than the car models found in Gran Turismo 3. And it shows: thanks to this increased level of detail, GT4 edges the series ever closer to photorealism.

By far the biggest of Gran Turismo 4s many attractions.
