Tomy AFX cars are a Japanese brand of slot cars, which are micro radio- or battery-operated autos that run on miniature tracks. Hobbyists typically use various models of Tomy AFX cars for competitive slot racing.
When slot cars first appeared in 1912, they were primarily used to accompany miniature train sets. Slot racing became popular in the United States in the 1960s. Between the 1960s and 1970s, hobbyists rallied in public slot racing courses and hosted televised high-stakes events. A study for American Machine and Foundry reveals that in 1968, public slot racing tracks had become more numerous than bowling alleys.
