Checkout the full 2025 NASCAR Iowa Corn 350 Results, Iowa Speedway, 2025 NASCAR Cup Series.
William Byron took a masterful fuel gambit in a caution-filled final stage at Iowa Speedway to secure his second victory of the season and reclaim the championship points lead.
Stage 1 winner Chase Briscoe ultimately settled for second 1.192 seconds adrift while Brad Keselowski rounded out the podium, 1.378 seconds clear of Byron.
Further back, Ryan Blaney showed resolve in the Team Penske No.12, steadily carving his way forward and ultimately finishing fourth after battling with Ryan Preece and last week’s Brickyard 400 winner Bubba Wallace who finished fifth and sixth respectively.
The remainder of the top ten was rounded out by Alex Bowman, Carson Hocevar, Joey Logano, and Austin Dillon.
Chase Elliott who briefly led mid-race and appeared poised for a potential victory ultimately faded after contact with his teammate Kyle Larson and an untimely pit stop, finishing 14th but still maintaining a strong points position as the playoffs loomed.
Larson was uncharacteristically absent from the lead fight, finishing outside the top 25 amid mechanical gremlins and pit road penalties.
