"MotorSport" marks the first time Migos, Minaj, and Cardi B have worked together on a song; although
Offset had already collaborated with Minaj on
London on da Track's "No Flag", and with Cardi B (his wife at the time) on her own track "Lick". On October 25, 2017, radio station
Hot 93.7 confirmed that a collaboration between Migos, Minaj, and Cardi B would be released two days later. On October 26, the night before its release, Migos previewed the track on
Power 105.1's music celebration, Powerhouse. On October 27, the song premiered online and was released worldwide as a download. It was also rumored that Cardi B and Minaj were dissing each other on the song in the midst of an
alleged feud between the two, which both rappers denied. Minaj commented on the rumors saying that the song was originally only a collaboration between her and
Quavo, that she was "in full support of Cardi B's 'MotorSport' feature" and that "the conspiracy theorists are just so tired", == Composition ==
