From NBC's official press release:

Mike (Justin Bruening) and KITT (voiced by Val Kilmer) are trying to track down a stolen serum that maximizes the recipient's physicality before it gets into the wrong hands. With the help of the lab's research assistant, Billy (Paul Campbell) learns some information about the serum that will help Mike when he takes on the now powerful thief. Meanwhile, Sarah (Deanna Russo) is overwhelmed with her new duties and quickly learns how much work it will take to reinstitute the Foundataion for Law and Government. Smith Cho stars. Kevin Alejandro and Mini Anden guest star.

Before 2008 came to a close, NBC treated fans of Knight Rider with "Knight Fever," the episode that was shot between "A Knight in Shining Armor" and "Journey to the End of the Knight" but never aired.  The installment saw Mike trying to stop the spread of a computer virus that threatened a total global meltdown.  It also saw a jealous Mike when Sarah reconnected with a former boyfriend, portrayed by guest star Jeffrey Pierce of The Nine fame. This week, actress Vanessa Williams will be gracing the action drama series and she'll be playing a character that is quite different from her comic/ villainess role as former magazine creative director turned editor-in-chief on Ugly Betty.

Though NBC is not commenting on the show's future, it seems that Knight Rider has run out of gas.  After a less than stellar showing this fall and rumors of a revamp, the network has decided to cut the series' original order by four episodes, scheduling its final hour to air on February 25, according to Zap2it.com.

Last month, it was announced that NBC was reformatting the show in an effort to more closely resemble the storyline of its predecessor.  Yancey Arias, Bruce Davison, and Sydney Tamiia Poitier's characters are being removed from the series starting with a two part episode scheduled to air in January 2009.  Moving forward, the show will continue with a more character driven focus on Michael and KITT.  On December 3, however, it was announced that network was reducing its season order to 17 episodes.  The five remaining scripts will be utilized if the show is renewed for a second season.

As part of NBC's “Green is Universal” week, Knight Rider is incorporating some environment-friendly storylines in tonight's episode of the ‘80s revival action drama.  So far, fans know that the current KITT, voiced by actor Val Kilmer, sports some solar panels and is based on the Ford Mustang.  But beyond that, producers have not disclosed information on its “fuel-efficient” qualities the next-generation vehicle could boast.

Tonight, however, fans might see a new fuel-efficient KITT hit the road in the episode called “Knight of the Zodiac.”  Read on for a preview.

Things are changing on the set of Knight Rider with today's announcement that nearly half of the main cast will be leaving the show after the first 13 episodes. Knight Rider is making a dramatic course correction by dumping Yancey Arias, Bruce Davison and Sydney Tamiia Poitier and severely changing the basic structure of the show.

Instead of working for the government and dealing with national security issues, Michael Knight (Justin Bruening) will now be working on his own, helping out ordinary people with their personal problems. The format brings the show closer to the original Knight Rider series.

A lot of buzz has been generated by Knight Rider, mostly for its lackluster performance on primetime television.  The NBC show, which is a remake of the 1980's cult classic, promised to bring spunk to the old Knight Rider, which starred David Hasselhoff.  This year's Knight Rider stars Justin Bruening as Mike Traceur, the son of Michael Knight and Jennifer Traceur from the original series.  Other cast members include former Young and the Restless star Deanna Russo as Sarah Graiman, Bruce Davison as Charles Graiman, Sydney Tammiia Poitier as Carrie Rivai and Val Kilmer as the voice of KITT.

So far, Knight Rider has attracted the male demographic when it comes to viewership, and NBC has no problem with that. In fact, the show was recently given a full season order after averaging a 2.4 rating and garnering 7.4 viewers overall.
