The Grand Prix Manufacturers' Association said it respects Toyota's decision to leave the body, and left the door open for the Japanese manufacturer to rejoin in the future.
As revealed by autosport.com today, Toyota has left the GPMA, saying the body had achieved its goal after signing a Memorandum of Understanding with the sport's commercial rights holders that will lead to the car makers receiving a bigger share of Formula One's revenues.
However, autosport.com understands Toyota did not believe the state of conflict between the sport's governing body, the FIA, and the GPMA was productive. The Japanese manufacturer prefers to cooperate with the FIA to work on the sport's future.
The GPMA thanked Toyota for its dedication to achieving the body's goals and said it will continue working on addressing "the long term-strategic issues of Formula One".
"The Grand Prix Manufacturers' Association respects Toyota's decision to leave the GPMA and wishes to thank Toyota for the support and dedication it has shown to the other manufacturers and the sport," the GPMA said.
"During Toyota's tenure, the GPMA has agreed a Memorandum of Understanding with the sport's commercial rights holder and made progress in its discussions with the governing body.
"The GPMA will continue its efforts to address the long term-strategic issues of Formula One, and the manufacturers and their teams remain dedicated to establishing a satisfactory regulatory structure and finalizing a new Concorde Agreement.
"The GPMA already cooperates with car manufacturers who are not formal members and Toyota will remain an intrinsic part of that process. Toyota will be welcome to rejoin the manufacturers' alliance at a later stage."
