Polyphony Digital boss Kaz Yamauchi has claimed that GT5 offers "a complete online system" to gamers - and it's the first title in the series' history to do so.
Predecessor Gran Turismo 5 Prologue supported online racing with 16-player multiplayer - but Yamauchi says GT5 easily trumps it.
The jewel in the crown of the new game's PSN link-up is the Lounge Mode - news of which broke online last night.
It offers voice and text chat for up to 32 players, and allows fans to watch other people's races in real time.
"We're finally going to have a complete online system," he told the latest issue of OPM.
"What's really unique about the online GT5 is 'My Lounge'. You can gather here, you can race together here, and you can actually watch other people race from this room."
Gran Turismo 5 is due for release on November 2.
