Speed Racer X, known in Japan as Mach Go Go Go (マッハGoGoGo Mahha Go Go Go ), is a remake of the original 1967 series produced by Tatsunoko Productions, the same studio that did the original. The show originally aired in Japan in 1997 on TV Tokyo and lasted only 34 episodes of a planned 52.
An English adaptation was later produced by DiC Entertainment and aired in the United States on Nickelodeon's short-lived action block, Slam. This show was quickly taken off the air (with only eleven episodes dubbed) due to a lawsuit between DiC and the Santa Monica-based Speed Racer Enterprises, the company which owns the American rights of the franchise.
In this version, Rex Racer does not run away, but is presumed dead after an accident while testing out the Mach 5. His father, Pops, later rebuilds the Mach 5 with a new safety system called "Safety Seven", which protects its driver. Rex's younger brother and Pops' second son, Speed, decides to follow up on his brother's footsteps. Trixie appears in this series as a reporter who befriends Speed, with Spritle being her younger brother now (as opposed to being Speed's younger brother in the original).
There are also differences that exist even in the original Japanese version. Aside from Gō's different surname (Hibiki), other characters were replaced entirely, but have similar roles. For instance, Mai Kazami is the "Michi Shimura" (the original Trixie) of this series, with her younger brother Wataru representing "Kurio Mifune" (the original Spritle). Although Gō's father is still called Daisuke, his mother (Aya Mifune in the original) is now known as Misuzu.
