Diablo Infernus is a beta vehicle that appears in Grand Theft Auto III. The car is a variant of the original Infernus. The car is cut from final version of GTA III possibly because the car is very sporty to run around the streets of ghetto Portland. In the final version of game, the Diablos drive a Diablo Stallion. This vehicle is referred to in game by King Courtney which is telling Claude to steal him a Diablo Stallion in the mission Gangcar Round-up, but the audio was saying Diablo Infernus, this audio may have been traced back to the Beta.
