Since its introduction in the mid '90s, like similar games, the "Shutokō Battle" series never used licensed cars but the usual type designation such as "TYPE-86" and later "TYPE-AE86L3". Nicknames were used instead in the "Wangan Dead Heat" sidestory (. "Rapid Fire" for the "Nissan Skyline GT-R R33"). These "types" are actually the real chassis code used by the Japanese makers to designate the various grades of a lineup. As the graphics quality was improving with each release, from 16-bit 2D to 3D/CG 128-bit, the featured cars were becoming more and more similar to the actual cars appearance. In a similar way, the chassis codes became longer and more precise, allowing the player to determine each grade and to use the "rename car" feature. Inevitably, the game becoming a solid best seller, the Japanese makers forced Genki to buy the license of their cars. The very first Genki licensed game was Wangan Midnight for PlayStation 2 (), while the first licensed "Shutokō Battle" was Shutokō Battle Online released on PC, the 9th of January 2003. Since then, every Genki racing game uses licensed makers, and ingame cars with Honda chassis codes don't appear anymore in the Shutokō Battle games (However, Honda is licensed in the Kaido Battle series).
