Qirex Tigron Enterprises (formerly known as Qirex and Tigron before merging) are an Anti-Gravity racing team that competes in FXC46 and FXC47 under the name Qirex. Tigron appeared in FXC47 before merging with Qirex to form Qirex Tigron Research and Development from FXC48 to FXC49. They relocated and rebranded to Qirex Tigron Enterprises for the upcoming SSRLC. Qirex is one of the most well-known teams in AG racing history. However, its popularity slowed during the FX400 league and grinded to a halt at the league's sudden end.
