The FOX Sports-owned channel will see most of the channel’s live events broadcast on FOX Sports 1 or 2.
Presenter Mike Joy told viewers it had been an honour and privilege to present motorsports on SPEED.
“But now it’s time to turn of the ignition and turn in the keys. This is the end of SPEED in America,” he said.
“Farewell to the motorsports authority, SPEED.”
It’s not clear how the end will directly affect SPEED’s Australian channel.
