A member of the Crash Mania community called JumpButton was the first person to e-mail Darren Esau, who had left his e-mail address in Dr. Cortex and N. Gin's credit comments (available to listen only in the NTSC version). Darren Esau jokingly stated in his reply that "[JumpButton] disproved his theory that the only people who read video game credits are the developers themselves."

This game was originally going to be developed by Traveler's Tales Oxford (developers of Crash Twinsanity), and was actually going to be called 'Crash Clash Racing.' It had the same concept as the final game; fusing two cars together. According to one of the project's developers going by the alias FakeNina:

"[...] the racing game would be set in Crash's head, with the rest of the Crash team traveling inside Crash's brain, with the tracks all based around Crash's dreams and memories."
