Stewart Haas Racing shutdown and sold 3 charters, though 2 of them are in limbo with the 23XI and Front Row Racing lawsuit against NASCAR. Haas kept the final charter and will have Cole Custer drive #? Ford Mustang, it will be a RFK satellite team.
RFK Motorsports bought the 3rd SHR charter and expanded to 3 teams with Ryan Preece in the #60 Ford Mustang.

In other Motorsports news Honda and Nissan/Mitsubishi will be merging into one company. It isn't known how the 3 company's will continue however Honda will have controlling interest of the new company. I expect most of Honda's lineup to stay unchanged, Nissan will probably focus on Trucks and SUVs and possibly sports cars, Mitsubishi will probably be retired or remain as cheap compact car brand.
