effects computer-generated. Along with the Mach Five, the movie features the "Mach 4" and the "Mach 6", two different single-seater cars created specifically for stunt races. The designs of the Mach 4 and Mach 6 are vaguely reminiscent of the Mach Five's (as in the original American comics), although the only functions the Mach 6 features are the jump jacks, which are standard equipment in race cars in the movie. Little about the Mach 4 is known, as it appears only briefly in the film and is portrayed as a red-colored companion to the 6. The film portrays the Mach Five as initially a street legal family vehicle, allowing for it to feature a rear compartment that Spritle and Chim-Chim later use to stow away in the vehicle. The Mach Five is later modified with gadgets and becomes Speed's alternate car for off-track races such as the Casa Cristo 5000, as well as everyday driving like a normal car. The Mach Five originally belonged to Speed's older brother Racer X. Rex, who relinquished ownership of it to Speed before he left the Racer home. Speed's main car for races on the WRL track (Thunderhead, etc.) is the Mach 6. The Mach 6 was destroyed in a fixed race, but was later rebuilt for the film's final race. The steering wheel hub is still present on this version of the Mach Five. Although most of the original functions of the car are still intact, some are activated by different buttons. The underwater functions are abandoned completely and replaced with new functions exclusive to racing combat. Instead of being built with these features from the beginning, the special functions were added to the Mach Five in order to enter it in the Casa Cristo 5000. The features that are still kept in this incarnation are: Auto Jacks Grip Tires (Not as belt tires but as crampon tire spikes.) Deflector Rotary Saws Homing Robot The functions abandoned in this version of the Mach Five are: Frogger Mode Evening Eye The functions on this Mach Five are: (*)New functions are represented with Bold Italics. Control A = Jump Jacks (Originally called the Auto Jacks) When pressed, the car releases and immediately retracts long automated car jacks that make the car jump over any hazardous obstacle. The car no longer releases these jacks to boost it for any repairs and adjustments. It is considered a
