"The 1991 movie Knight Rider 2000 saw the first KITT (Knight Industries Two Thousand) in pieces, and Michael Knight himself reviving the microprocessor unit, which is eventually transferred into the body of the vehicle intended to be the original KITT's direct successor, the Knight 4000. The new vehicle was a modified 1991 Dodge Stealth, appearing similar to the Pontiac Banshee prototype. However, no reference to this storyline nor any appearance of the Knight 4000 is made in the new series or its 2008 pilot movie. In Knight Rider 2000, it is stated that most of the Knight 2000 parts had been sold off. However, Graiman's garage in the 2008 pilot shows a more complete collection of parts than in the boxes recovered by Michael Knight in the 1991 film Knight Rider 2000. This adds to the mystique of the current whereabouts of the original KITT in the time-frame of the new series.
In a seemingly peripheral spin-off series called Team Knight Rider, KITT is seen as the shadow, an advisor. Later on it is revealed that "The Shadow" is actually a hologram run by KITT. In "Knight of the Living Dead", Graiman states a third KITT, a back-up, exists. When KITT is about to die, his memories are downloaded so the third KITT can use them, however in the end the third AI is not used."
