Turbo Boost's primary purpose is to provide KITT with the ability to gain vertical momentum and send him “jumping” through the air. Another ability of the turbo boosts is to provide a dramatic increase in purely horizontal speed for a short duration. However, the latter feature is almost never used, especially because Pursuit Mode achieves the same purpose. Explanations in the series of the Turbo Boost's function range from near-instantaneous volume increase in the tires to thrusters placed in the back. Turbo Boosts are usually controlled by on-board computers to provide the maximum height and precise landing spot needed.
