DriveClub's Season Pass and free additional content has been detailed by Evolution Studios on the PlayStation Blog.
Numerous free cars and tracks will be added to the game every month until June, 2015. In all, 47 cars (of which 38 are premium and nine are free) will be added to DriveClub during the first eight months, in addition to 80 new liveries, 11 new tracks, and 176 new campaign events.
You will need to purchase the Tour Packs to gain access to the new events and the Livery Packs to unlock the liveries though the tracks themselves will be free.
The Season Pass costs €24.99, a saving of 60 per cent compared to the price of buying all of the DLC individually. You'll get some idea of the content you can expect and when it will be made available from the image at the top of this post.
Free post-launch updates to the game will add a weather system and a new photo mode while Evolution has also confirmed that the new Mercedes AMG-GT will be made available in DriveClub for free later this year.
DriveClub is set for release on October 8th exclusively for PS4 and will be available as part of the PlayStation Plus Instant Game Collection.
