This vehicle is the 3rd generation Swift Sports, a sports version of the 3rd generation Swift, a mass-market model of Suzuki. From the first generation Swift (Japanese name: Ignis) to the second generation Swift, the Swift competed in the JWRC (Junior World Rally Car Championship), and the second generation Swift became the JWRC champion car. The Swift's short overhangs and compact body size made it highly suitable as a rally base vehicle. Furthermore, the 3rd generation Swift Sports, based on the 3rd generation Swift, had a much more rigid body and lighter weight than its predecessor, further enhancing its natural potential as a rally machine. However, the third-generation Swift Sport did not compete in the WRC as a rally machine, partly because the JWRC regulations themselves were abolished. On the other hand, the 3rd generation Swift Sport, which further developed the concept of its predecessor, was well received by Japanese racing drivers and many sportsman drivers, and its straightforward handling characteristics that directly reflect the driver's control and its high durability made it an excellent choice not only as a rally base machine but also as a machine for improving driving skills. The car was highly acclaimed not only as a rally base machine, but also as an excellent car for improving driving skills.
