KITT is the analog name for the fictional scifi advanture series Knight Rider character artificial intelligence mounted in a highly advanced very mobile weapons platform disguised as a sleek contemporary automobile, and that series' subsequent spin-offs and continuations.
The original full name stood for Knight Industries Two Thousand, whereas the updated 2008 movie refers to the successive AI unit designated as the Knight Industries Three Thousand.
KITT's features
KITT is loaded with special features such as the commonly-used Turbo Boost, which allows quick bursts of speed or jumping over obstacles. KITT could also drive himself, but perhaps his most distinct and recognizable aspect was his front mounted scan bar which, among other things, allowed KITT to "see". KITT's body panels were coated with an advanced "molecular bonded shell" armor coating which would resist conventional weapon fire as well as most artillery and explosive blasts although a strong direct hit by those attacks could cause severe damage. KITT underwent a major modification during a refit in 1985 which included the addition of "Super Pursuit Mode" and a convertible top.
KITT had many features, most of which had an activation button associated with them that were on panels mounted on either side of the steering wheel or on a console mounted on the ceiling of the interior. Many of these button functions seem to change around, appearing and disappearing, or rearranging from episode to episode. Some were used once and never seen again.
