Frustrated Kyle Larson boils over in radio rant during rough Iowa Cup race

Larson found himself in the wrong place a the wrong time often during the chaotic race, losing ground in his fight to win the regular season title

The NASCAR Cup race at Iowa Speedway was not kind to Kyle Larson, who was hoping to carry the momentum forward from a runner-up finish in the Brickyard 400 one week ago.

Larson's day started to unravel when he and teammate Chase Elliott kept finding each other on restarts. The two Hendrick Motorsports drivers slammed doors multiple times as they fought over a position inside the top ten.

Then, with just under 100 laps to go, things really went sideways while he battled Christopher Bell for sixth position. Bell got into Larson, nearly wrecking him and costing the driver of the No. 5 several spots. To make matters worse, Ross Chastain filled the hole in the next corner, using up Larson some more. He fell back through the field as more cars bounced off of him.

Radio rant

"F*** every single motherf****** -- damnit," radioed Larson in frustration. Moments later, the caution flew as Bell spun in a separate incident with Tyler Reddick.

"How much f****** room do I have to leave people?" Larson lamented to his team. "I've been trying to be good to teammates, trying to be a good competitor, and it hasn't gotten me anywhere the last f****** hour."

While crew chief Cliff Daniels played the role of cheerleader, it didn't change the fact that things were only about to get worse.

Soon, after, Larson sustained nose damage while checking up for a spinning car, forcing the team to make repairs. He was also involved in another caution with a slowing Ty Dillon.

Larson ended the day 28th of the 30 cars that remained on the lead lap. This was a major blow in his fight to win the regular season championship, which brings with it some extremely valuable playoff points. He is now 45 points back from the lead, which is currently held by his teammate and Iowa race winner William Byron.
