Polyphony Digital has updated its website to include new sales figures for Gran Turismo, the Japanese developer's marquee racing franchise. Among other things, we learn that the latest entry in the series, 2013's Gran Turismo 6, has now sold more than 5 million copies (5,010,000 to be exact). Another standout figure is 76.8 million, which is the total number of Gran Turismo games sold to date.

These figures are accurate as of June 30. Prior to this, the figures were updated for March 31, when Gran Turismo 6 sales stood at 4.96 million (via NeoGAF); this means the game shifted some 50,000 copies in three months. This may sound like a small number, but note that it's for a PlayStation 3 game released three years ago.

The sales chart also shows that Gran Turismo 3 A-Spec is the best-selling entry in the franchise, having shifted some 14.89 million copies. The worst-performer is Gran Turismo 4 Prologue, which has sold 1.4 million copies.

Below is a rundown of Gran Turismo franchise sales, on a worldwide basis. You can visit Polyphony's website to see a breakdown by geographic region.

The next Gran Turismo game is Gran Turismo Sport for PlayStation 4, which is scheduled to launch in November. Looking ahead, Polyphony boss Kazunori Yamauchi has told fans to expect Gran Turismo 7...eventually.
