Which Gran Turismo game holds the Guinness World Record for largest car library?

Gran Turismo 6 holds the Guinness World Record for the largest car library in a racing videogame.

Guinness World Records recorded Gran Turismo 6 with 1,237 cars as of March 31, 2017. The PlayStation 3 game launched in December 2013 with 1,200 cars, and additional vehicles added through updates helped raise the total.

Gran Turismo 6 was released worldwide on December 6, 2013. Its enormous garage included production cars, race cars, concept vehicles, and historic machines, continuing the series’ reputation as a digital car encyclopedia.

The wording can cause confusion because the record is tied to a particular measurement date, and later games may have larger rosters under different counting methods. The Guinness record cited here specifically identifies Gran Turismo 6 and 1,237 cars.
