The Sentinel XS is the tuned version of the regular Sentinel sports compact, featured in Grand Theft Auto: Vice City, Grand Theft Auto: Vice City Stories, Grand Theft Auto V and Grand Theft Auto Online. It is manufactured by Ubermacht in the HD Universe. The car is related to the Mafia/Leone Sentinel, gang car of the Leone Family in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories. GTA IV also features a modified Sentinel badged Sentinel XS, however it is essentially a modified counterpart and not counted as a separate vehicle.
