The first-generation Alto Works was born in 1987 based on the second-generation Suzuki Alto, which was manufactured under Japan's unique mini-car standards. It combined a three-cylinder turbo engine with a DOHC four-valve head, which was revolutionary at the time, with a small displacement but lightweight body, and demonstrated performance that surpassed that of sports models with larger displacements. The Alto Works underwent several model changes, but continued to demonstrate extremely high performance in rallies and gymkhanas in Japan, and became a car loved by many drivers. However, with the market for sports models based on the kei car standard going down, Suzuki discontinued the production of the 4th generation Alto Works in 2000. Finally, in 2015, the Alto Works made a comeback. The fifth-generation Alto Works is based on the eighth-generation Alto with a completely new frame structure, and it is significantly lighter and more rigid than the previous model while improving safety.
