The 2025 installment of the Iowa Corn 350 proved a welcome return to Newton, Iowa, as the race built on the success of last year. At 7/8 of a mile long and with 10 degrees of banking in the frontstretch, balanced by 4 in the back and 12-14 in the turns, this is a track that is set up for speed. So it proved as Byron took the win in another thrilling spectacle served up by the NASCAR Cup Series.
