The car is automatically patched in for users across all platforms. This means that the update will automatically download and players will be able to simply select the car in their garage. No DLC is needed to be manually downloaded. Interestingly enough, it replaces the current Mustang GT in the game, which seemed to be a 2013 body type. Why they didn’t just add it as a separate car is a mystery, and one that will likely annoy fans of the current body style. Xbox One, Xbox 360, PS3 and PC users should be able to access the car right now, but unfortunately, it has not yet been added to PS4.
We’re not sure why it hasn’t been put on the platform yet, but hopefully it’s a simple oversight that will be quickly remedied. We’ve reached out to EA for comment and will update if we hear any news.
