Sukup Manufacturing has been announced as the title sponsor of this year’s INDYCAR races at Newton’s Iowa Speedway. Sukup Manufacturing Company is based in Sheffield, Iowa, and is the world’s largest family-owned and operated manufacturer of grain storage, drying and handling equipment. For the past three years, Hy-Vee had been the title sponsor for Iowa Speedway’s INDYCAR races. But the Iowa based grocery store chain announced in February it was dropping its title sponsorship, but would stay on as a significant sponsor.  Sukup has sponsored the Sukup 100 INDY NXT by Firestone race at Iowa Speedway in the past, and has been a longtime sponsor of INDYCAR Pole Day. The 2025 Sukup INDYCAR Race Weekend at Iowa Speedway is Friday, July 11 through Sunday, July 13. The two NTT INDYCAR SERIES races will be held at 5 p.m. Saturday, July 12th and 2p.m. Sunday, July 13th. Tickets for the Sukup INDYCAR Race Weekend will go on sale Tuesday, April 15.
