The NASCAR O’Reilly Auto Parts Series transitions from two consecutive drafting venues to the left-and-right-turning Circuit of The Americas this Saturday (3 p.m. ET, The CW, PRN Radio, SiriusXM NASCAR Radio).
The 65-lap race in Austin, Texas, will be the first of four road-course races on the 2026 docket for the O’Reilly field, with Watkins Glen International (May 9), Naval Base Coronado (June 20) and Sonoma Raceway (June 27) to follow.
Connor Zilisch and Shane van Gisbergen return to do battle in the O’Reilly Auto Parts Series, wheeling the No. 1 and No. 9 Chevrolets, respectively. Brent Crews additionally makes his O’Reilly debut, with updated NASCAR eligibility requirements allowing the 17-year-old pilot to race on road courses and oval tracks 1.25 miles or shorter before his 18th birthday on March 30.
