Batman: Arkham knight will include the tumbler from Christopher Nolan's Dark Knight Franchise

Warner Bros. has not yet formally declared the Tumbler will be accessible to play in the game and, therefore, there's no data on whether the vehicle's devices will be incorporated, or if it can change into the Batpod.

                                     Below is the picture of the Arkham knight's tumbler.

Batman: Arkham Knight's first extension, A Matter of Family, centered around Batgirl and was produced remotely at Batman: Arkham Origins studio WB Games Montreal.

The PC version of Arkham Knight is as yet having issues. Therefore, the game is still inaccessible to purchase at retailers and DLC has been postponed. An interim patch is required to be discharged in the not so distant future.
