Japanese Generation 1 cartoon continuity
Car Robots cartoon
At a point when the 3 Car Robo Brothers were trying to cheer up a forlorn Gelshark, Speedbreaker suggested that Gelshark should undergo a Power Up like the one given to him and his brothers by God Magnus's Energon Matrix. When describing the nature of their Power Up to Gelshark, the brothers referred to a side effect that could rapidly wear their bodies out, as they didn't yet have enough control over their new powers. Speedbreaker noted that this side effect conflicted with a health diagnosis that confirmed the brothers' Spark Engines to be in working order, to which God Magnus explained that the brothers' rapid fatigue by the Power Up was due to the Energon Matrix's power being meant only for those of the Convoy Class rather than any ordinary Transformer.

The concept of the Spark Engine was developed by Doctor Daichi Ōnishi. In 2002, it was perfected with the use of go-brillium, an invention of Doctor Ōnishi's colleague Doctor Haruma Gō, in response to the invasion of Earth by the Mutants. The scientists thus upgraded the only Autobots left on Earth, the Spychangers, with Spark Engines, turning them into the Super Spychangers, who gained incredible powers. Super Artfire gained pyrokinesis, Super Ox received super strength, Super Wars was imbued with invulnerability, Super Counter Arrow discovered amazing speed, Super Eagle Killer could fly, and Super X-Car gained the capability to manipulate gravity.

When Side Burn received a Spark engine, his speed and acceleration increased to infinite levels, and he gained the ability to teleport short distances on the highway. Robots in Disguise Deluxe Side Burn toy bio Prowl added one to his configuration to enhance his mobility and searching ability. Robots in Disguise Deluxe Prowl toy bio <ref>Given that the packaging bios for the "Super" redecoes of Side Burn and Prowl merely describe their personalities and abilities, it would seem that the "Super" bios were accidentally swapped with the regular bios at some point in production.</ref>
