overview
Interest in the show declined, leading to its cancellation by the end of the season. Hasselhoff, knowing that the show was coming to an end, attempted to make a "series finale" and helped conceive the story "The Scent of Roses" with his wife at the time, Catherine Hickland, who played Michael's love interest Stephanie Mason in past episodes. The network instead aired "Voodoo Knight" as the final episode.
A new street-smart mechanic, played by Peter Parros, was added to the cast in addition to Bonnie. Of all KITT's features added in the fourth season, the most important of them is "Super Pursuit Mode". KITT could also convert into an open convertible. Both cars were designed and built by customizer George Barris.
This season also marks the final appearance of Bonnie Barstow, RC3, and the Knight Industries Two Thousand in its original form. KITT's final appearance in the Knight Rider franchise was in the 1991 made-for-TV movie Knight Rider 2000.
