The Grand Prix Manufacturers Association (GPMA) was an alliance of car manufacturers that participated in Formula One formed (like its predecessor GPWC) to act as a tool to assist the companies in bargaining with Bernie Ecclestone for an agreeable extension to the 1997 Concorde Agreement, the contract by whose terms the teams compete in F1. It was then superseded by the Formula One Teams Association, founded in 2008, and disbanded in 2014.
(as at time of formation of FOTA)
On 27 March 2006, Formula One's five "rebel" manufacturer-backed teams signed up to the 2008 World Championship.
