Choro-Q is a brand of toy cars with pull-back motors owned by TakaraTomy. Unlike typical toy cars, they are not accurately-proportioned miniatures, but rather super deformed to make them cuter. They were introduced to the Japanese market in 1979, and were once sold in Western markets under the name Penny Racers. They were an immediate hit, to the extent that after only a few years, they found their way to Takara's Microchange line as common household objects for Microman-scale robots to be disguised as. This is the reason why the Generation One Autobot Mini-cars look completely different from the standard Autobot cars.
