The Axelerators (known as the Small Autobot Cars in America) are an Autobot subgroup whose members' engines become their gun in robot mode. They are the counterparts to the Decepticon subgroup the Skyscorchers.
The Axelerators were initially released in the European market in 1993, during the "transitional" time when the Transformers toys took on the new Generation 2 sigils, but the packaging lacked the "Generation 2" line-name. They were slightly recolored for American release the same year, with the transparent pink plastic of their windows and lightpipes being replaced with a smokey grey plastic that was much harder to see through. They were released again in the UK in 1994 in G2 packaging, but the toys were identical to the original European-market release.
