2023 GT World Challenge America

The 2023 Fanatec GT World Challenge America Powered by AWS was the seventeenth season of the United States Auto Club's GT World Challenge America, and the sixth under ownership of SRO Motorsports Group.

The season began at Sonoma on March 30, and ended at Indianapolis on October 8.

Eric Filgueiras and Stevan McAleer won the Pro class championship for Rennsport One (RS1) in the new Porsche 911 GT3 R, one year after they won the 2022 GT4 America Series Silver class title. George Kurtz and Colin Braun won the Pro-Am championship for CrowdStrike by Riley.

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]
