NEWTON, Iowa — An extraordinary spat of cautions in Sunday’s Iowa Corn 350 Powered by Ethanol allowed William Byron to save an extraordinary amount of fuel, and that proved the difference in Byron’s second victory of the season and first since the DAYTONA 500.
Squeezing 144 laps out of his fuel cell at an Iowa Speedway track where the fuel window is roughly 100 laps, Byron crossed the finish line ahead of a trio of pursuers—pole winner Chase Briscoe, first and second stage winner Brad Keselowski and defending race winner Ryan Blaney—all on different strategies.
