Sutorīto RPM: Overdrive

Sutorīto RPM: Overdrive functions very much in the same way as an Extra or Battle Stage would function in Initial D. However, this series only had 4 Episodes, all of which were new battles not seen in the Anime. It is based on the manga by the same name, which adds new battles that took place in between the Events of Impossible and Memories. While its stated that a total of 16 battles happened inbetween those two seasons, the anime and manga only adapt 8, all of which are in chronological order.
