Tony Stewart has purchased the All Star Circuit of Champions Sprint Car Series, one of the oldest, traveling winged sprint car tours in the country.
Stewart has also reached a separate deal with Rob Hunter and Shane Helms, principals of the Renegade Sprint Series, that will merge both series together under the All Star Circuit of Champions banner beginning this year.
The acquisition is just the latest in Stewart's growing portfolio.
The three-time NASCAR champion also owns Eldora Speedway in Rossburg, Ohio, and fields two World of Outlaws cars out of Tony Stewart Racing. He also is co-owner of NASCAR's four-team Stewart-Haas Racing, which won the Sprint Cup title last season with Kevin Harvick.
