What happened
Polyphony Digital announced Spec IV as the start of Gran Turismo's 30th-anniversary celebration.
The content is split across October and December rather than arriving as one patch.
The practical change: Treat the two months as separate update checks and wait for Polyphony's final car list before planning purchases or event builds.
What is confirmed
- Sportsland SUGO comes in October and Autumn Ring returns in December.
- Twelve cars will be added across both updates.
- Online Drift Trials and Shuffle Races are included.
- Family Mode offers shared two-player races with adjustable assists and independent controllers.
What this means for players
Players must check both releases instead of assuming every feature appears in October.
Family Mode is designed for players with different experience levels on one console.
What is still unconfirmed
The exact dates, 12-car roster and distribution of every feature between the two parts are not yet published.
What to do next
- 01Install the October update before looking for Sportsland SUGO.
- 02Recheck the December notes for Autumn Ring and remaining features.
- 03Wait for the official vehicle list before planning credits.
