One of America's newest race tracks, Iowa Speedway is located in Newton, Iowa and has been in operation since 2006. The 7/8 mile oval was designed and built under the auspices of NASCAR champion Rusty Wallace at a cost of approximately $70 million. The D-shaped oval is patterned after Richmond International Raceway, scene of some of Wallace's greatest success during his career.

Purchased by NASCAR in 2013, Iowa Speedway has a seating capacity of more than 30,000, together with a unique multi-tiered RV viewing area along its 869' long backstretch. The track hosted NASCAR Xfinity and Craftsman Truck Series events annually starting in 2009 before finally receiving a Cup Series date in 2024, and its NTT INDYCAR Series races have long been popular among that series' fans.

iRacing features two versions of the main Iowa oval: a version based on the original scan, and a version that reflects its partial repave from prior to its first Cup race in 2024. In addition, Iowa Speedway features a nine turn, 1.3 mile road course utilizing most of the main oval along with a highly technical infield section, multiple Legends ovals, and an iRacing-designed rallycross course.
