Albany is an automotive company in GTA IV which produces cars such as:
Due to this, it is a take on Cadillac. Albany, along with Vapid, seem to be the largest manufacturers in the game, as they produce a large model base, bigger than the other manufacturers.
Although the manufacturer parodies Cadillac, The Washington is based off the Lincoln Towncar L which in the game is the long wheelbase version of the Admiral which is made by Dundreary. However, Albany and Dundreary may share vehicle platforms, much like manufacturers do in real-life, accounting for the similar designs of the Admiral and Washington. Ironically, the name "Albany" is actually a capital city name based off from New York.
