is a powered toy car generally 1:32 in scale equipped with 4WD. The cars can be used for miniature auto racing, being built to race around a U-shaped track. History The Mini 4WD originated in Japan in 1982, when toy manufacturer Tamiya introduced Mini 4WD race cars. A Mini 4WD race car is a 1:32 scale kit featuring four-wheel drive powered by an electric motor using a pair of AA batteries. A single electric motor turns both axles. These kits snap and screw together without the need for glue. By the late 1980s, the Mini 4WD hobby was well-established in Japan, and it began taking off in the United States as well. In February 1989, several American and Japanese companies unveiled their versions at the annual toy fair in New York. In late 1989, an average Japanese boy owned eight to 11 Mini 4WD cars. By November 1989, Hasbro introduced their Record Breakers: World of Speed series of cars, imported from Japan. Mattel, Matchbox, and others were also expected to release their own versions. By the 2000s, many other companies had ventured into the Mini 4WD market, including Tokyo Marui, Kyosho, Academy, Aoshima Bunka Kyozai, Matchbox, Revell, Hot Wheels, Tonka, Hasbro, Auldey and Bandai. On June 23, 2019, the Tamiya Mini 4WD Asia Challenge was held at the Glorietta shopping mall in Makati, Philippines. Over 200 participants (including 87 foreigners) attended the event. To commemorate the event, Tamiya released a 1:32 scale mini 4WD car of the distinctive Jeepney named "Dyipne".
