The preliminary calendar was released on July 29, 2022, featuring 14 races across seven rounds.[1] In September, an updated schedule was released, postponing the event at Circuit of the Americas by two weeks and bringing the Road America round forward one week.[2] An additional change was announced on October 17, moving the NOLA round from February 24–26 to April 28–30 to alleviate a clash with the Kyalami 9 Hours, as well as allowing the 2023 BoP test to be completed before the start of the season.[3]
