The original Gran Turismo game for the PlayStation 1 sold almost 11 million copies, making it the best-selling game on the platform.

Gran Turismo 1 features 140 different vehicles, including two Honda NSX models that were cut from the American and European releases of the game.

Sony worked on the game for about five years, and Gran Turismo 1 cost them approximately $5 million to develop.

Gran Turismo was among the first PlayStation games to make full use of the DualShock controller with analog sticks for the PS1.

Due to licensing agreements with real car manufacturers, Gran Turismo 1 was not allowed to show any kind of car damage.

Sony wanted Porsche cars in Gran Turismo 1, but Porsche already had an exclusive licensing agreement with Electronic Arts, which prevented those cars from appearing in the game.

While Sony secured licenses with major car brands for Gran Turismo, they used generic tires in the game.

Japan received an updated version of the game called Gran Turismo: The Best which included additional content.

While revolutionary for its realism, several cars in Gran Turismo 1 have incorrect horsepower or weight compared to their real-life counterparts.

The American and European versions of Gran Turismo 1 feature completely different soundtracks, giving players on different continents a distinctly different mood while playing the game.
