This is a list of vehicle brands that appear throughout the Grand Theft Auto series. They were very rarely encountered in the 3D Universe games, however their use was greatly expanded in the HD Universe, where every car has a designated brand.
In Grand Theft Auto: San Andreas for PC, there is a data file titled carcols.dat which names some vehicle brands: one known brand (Maibatsu), one later-known brand (Shitsu, not Shitzu) and two unknown brands (Nioka and Kunst). So far, no one can tell which vehicles these brands have produced in the game.
Because of the absence of their vehicles, Steel Horse, Willard, and Classique are the only vehicle brands in the HD Universe that have not reappeared in GTA V to date. The sole exception to this, the Stallion, is featured as a Declasse vehicle but still has the Classique badging. Willard vehicles appeared in the beta version though.
