Gran Turismo 4/Tracks

The game features 51 tracks, which are divided into 4 groups, World Circuits, Original Circuits, City Courses and Dirt & Snow. Many of which are new or modified versions of old Gran Turismo favorites. Notable real-world track inclusions are the Nürburgring Nordschleife, Suzuka Circuit, Twin Ring Motegi (with three Road Course configurations, as well as the Super Speedway) and Circuit de la Sarthe (Le Mans). There are also tracks modeled after world famous attractions such as New York City's Times Square, Hong Kong, Paris, and the Las Vegas Strip. The Hong Kong course is located in the Tsim Sha Tsui district, which, in its clockwise configuration, starts at Salisbury Road, passes through the city's waterfront and then Nathan Road.

The Città d'Aria course follows actual roads in Assisi, Italy. The race starts/finishes in the piazza in front of the temple Minerva. Just before the start/finish line on this course, written on the tarmac is an inscription in broken Italian: "Dio lo benedice — fate il suo guidare il più sicuro e divertirsi", which, when translated, means "God blesses him; make his driving the most safely and to have fun." On the Seattle circuit, the Kingdome, previous home of the Seattle Mariners, is visible next to their current stadium, Safeco Field. Kingdome was demolished in an implosion on March 26, 2000. A section of the Opera Paris course passing through Place de la Concorde was traversed by Claude Lelouch in the short film C'etait un rendez-vous.
