The S13 Silvia is the beloved car of Koichiro Iketani, self-proclaimed "#2 driver" of team Akina Speed Stars. He is of a caring character with mechanic knowledge, and oftentimes gives advises to Takumi and Itsuki. However, his racing technique is mediocre at best. Koichiro fainting on the passenger seat during Takumi's downhill cornering had later been told down among team.
