Notes

Changes Teams On July 14, 2022, Emerling-Gase Motorsports announced that they would expand to two full-time cars, with the No. 53, previously a part-time car, running full-time in 2023. One car would have one full-time driver with multiple drivers sharing the other car. On February 2, 2023, the team announced that the No. 53 car would be driven by team co-owners Joey Gase and Patrick Emerling (as well as previously announced part-time drivers Brad Perez and C. J. McLaughlin), making the No. 35 car the car that will have one full-time driver. On August 25, 2022, Front Row Motorsports announced that Zane Smith, who drives for the team full-time in the Truck Series, would run part-time for a Ford team in the Xfinity Series with entries being fielded in a collaboration with them (instead of FRM starting their own Xfinity Series team). On September 20, 2022, JD Motorsports announced that they would expand to three full-time Xfinity Series cars in 2023. The team downsized from four full-time cars to two in 2022. However, on February 9, 2023, the team revealed to TobyChristie.com that they would only field the No. 0 car part-time in 2023 due to lack of sponsorship. On October 7, 2022, it was announced that Truck and ARCA Series team AM Racing, owned by driver Austin Wayne Self, would expand into the Xfinity Series in 2023 and attempt to qualify for the season-opener at Daytona. On December 12, it was announced that AMR would field their new Xfinity Series car, the No. 25, full-time in 2023 and Brett Moffitt, who previously drove part-time for the team in the Truck Series, would drive it. On October 26, 2022, Jesse Iwuji stated in an interview with Dustin Albino from Jayski that he would like to expand his team to two full-time cars in 2023 if sponsorship can be found for a second car. However, on February 17, 2023, Kyle Weatherman, who drove for the team in 2023, revealed to TobyChristie.com that JIM would not field a second car and would also be cutting back their one car, the No. 34, to part-time in 2023 amidst the team's sponsorship struggles following the loss of the No. 34 car's primary sponsor, Equity Prime Mortgage, in a lawsuit and legal battle. On November 5, 2022, Mike Harmon Racing announced that Gary Keller would join the team as a co-owner after having been a co-owner of JD Motorsports from 2012 to 2022. The team will be back in the Xfinity Series in 2023 although they have yet to announce their 2023 plans. On December 19, Brandon Kauffman, the team's PR & Marketing Assistant, teased on the NASCAR Reddit page that the team would field the No. 74 car again in 2023. In 2022, MHR only fielded that car in the season-opener at Daytona when it had run full-time for several years prior. On January 13, 2023, the team announced that they would be renaming to CHK Racing after the addition of another co-owner, Michael Clayton Sr, as well as to reflect Keller's new co-ownership of the team. The No. 74 car will be fielded full-time while the No. 47 car will be fielded part-time. On November 16, 2022, Stewart–Haas Racing announced that they would be expanding to two full-time Xfinity Series cars in 2023. The second car will be driven by Cole Custer, who is moving back to the Xfinity Series after three years driving the team's No. 41 Cup Series car. On November 23, it was revealed that Custer would drive the No. 00, the same car number SHR used when they last fielded a second Xfinity Series car and Custer was the driver.
