Immortal Grand Prix DVD vol 1.jpg

IGPX: Immortal Grand Prix (IGPX インモータル・グランプリ) refers to two anime series co-produced simultaneously by Cartoon Network and Production I.G. The first is a "microseries" consisting of five 5-minute episodes, and the second is a 26-episode animated series loosely related to the first.

Koichi Mashimo co-wrote and directed the microseries, while Bee Train Animation and Production I.G animated it, and Bandai Entertainment acted as the North American distributor. The full-length anime series was handled by director and writer Mitsuru Hongo and was animated by Production I.G, with Bee Train returning for in-between animation. Production I.G president Mitsuhisa Ishikawa joined on as producer for the series. It was the first time he had worked on a joint U.S. Japanese production, due to the Pokémon companion franchise.

The series' English dub was produced by Williams Street in Atlanta, Georgia and Bang Zoom! Entertainment in Burbank, California. Both studios collaborated on the English script and casting, Bang Zoom directed and recorded the actors, and Williams Street handled the final mixing for the dub. IGPX was commended for being the first original series on Toonami.

An IGPX video game was released on September 12, 2006, for the PlayStation 2.

The program returned to the Toonami block April 28, 2013 at 2am/1c on Adult Swim.
