Knoxville Raceway draws one of the year's toughest sprint fields

A large field of World of Outlaws NOS Energy Drink Sprint Car Series entries will converge on Knoxville Raceway in Knoxville, Iowa, on June 12–13 for the final leg of the Premier Chevy Dealers Clash — the last official tune-up before the 65th NOS Energy Drink Knoxville Nationals presented by Casey’s (Aug. 12–15). Organizers expect one of the year’s toughest fields as regional and local contenders mix with national talent and World of Outlaws tour regulars. That depth should produce intense heat races and high-stakes battles for position and pride, and the weekend will serve as a key barometer of form and a final opportunity for many teams to fine-tune cars and strategies. The turnout underscores Knoxville Raceway’s continued role as a central venue on the sprint car calendar.
