NASCAR icon Kyle Busch, a two-time Cup Series champion who won more races across the sport's three national series than any other driver in history, has died at the age of 41, the racing series announced Thursday.
The Busch Family, Richard Childress Racing and NASCAR issued a joint statement Thursday saying that Busch died after being hospitalized earlier in the day as the result of a severe illness, three days before he was to compete at the Coca-Cola 600 at Charlotte Motor Speedway. No cause of death was given.
"On behalf of the Busch family, everyone at Richard Childress Racing and all of NASCAR, we are devastated to announce the sudden and tragic passing of Kyle Busch," NASCAR said in a statement. "Our entire NASCAR family is heartbroken by the loss of Kyle Busch. A future Hall of Famer, Kyle was a rare talent, one who comes along once in a generation. He was fierce, he was passionate, he was immensely skilled and he cared deeply about the sport and fans."
Busch was the younger brother of Kurt Busch, a NASCAR Hall of Famer.
The news comes 11 days after Kyle Busch radioed into his crew near the end of a Cup Series race at Watkins Glen asking a doctor to give him a "shot" after he finished the race. According to the TV broadcast, Busch had been struggling with a sinus cold that was exacerbated by the intense G-forces and elevation changes at the New York road course.
Busch finished the race in eighth place.
Busch competed at Dover last weekend and won the Trucks Series race for Richard Childress Racing. He finished 17th at the NASCAR All-Star race.
"Absolutely cannot comprehend this news," NASCAR driver and former teammate Denny Hamlin posted on social media. "We just need to think of his family during this time. We love you KB."
Added veteran NASCAR driver Brad Keselowski on X: "Absolute shock. Very hard to process."
Busch ranked 24th in the Cup Series standings this season, with two top-10 finishes in 12 races. The Las Vegas native won championships with Joe Gibbs Racing in 2015 and 2019. Busch was in his fourth season at Richard Childress Racing.

His last win came in 2023, his first with RCR.
From Las Vegas, Busch experienced unrivaled success across NASCAR's three national series winning a combined 234 Cup, O'Reilly Auto Parts and Trucks Series races -- more than any driver in history.
He had 63 Cup victories, which ranks ninth all-time, along with 102 O'Reilly Auto Parts wins and 69 Trucks victories -- both records.
"Throughout a career that spanned more than two decades, Kyle set records in national series wins, won championships at NASCAR's highest level and fostered the next generation of drivers as an owner in the Truck Series," NASCAR said in its statement. "His sharp wit and competitive spirit sparked a deep emotional connection with race fans of every age, creating the proud and loyal 'Rowdy Nation.'
"Our thoughts are with Samantha, Brexton and Lennix, Kyle and Samantha's parents, Kurt and all of Kyle's family, Richard and Judy Childress, everyone at Richard Childress Racing, his teammates, friends and fans. NASCAR lost a giant of the sport today, far too soon."
Busch's sudden death shocked the racing world Thursday.
"There aren't really words for today," driver Ricky Stenhouse Jr. posted to social media. "I've raced against Kyle for a long time, and anyone who's lined up next to him knows exactly what made him special, he gave you everything he had, every single lap, and he made all of us better for it. ... Rest easy, Rowdy. The sport won't be the same without you."
I just talked to him Friday. In complete shock, as we all are. The devastation and sadness is beyond words. Praying for Samantha, Brexton, Lennix, his entire family and loved ones...🙏 pic.twitter.com/4Z98jzgWIK

A polarizing figure known as "Rowdy" and "Wild Thing" for his post-race fights, regular feuds with other drivers and sometimes outlandish behavior, the multi-talented Busch stormed on the Cup Series scene in 2005 by winning Rookie of the Year.
The Indianapolis Motor Speedway, where Busch won the Brickyard 400 in 2015 and 2016 -- as well as the O'Reilly Auto Parts Series races those years -- remembered "Rowdy" as a "fan favorite, loved for his competitive spirit and passion."
Busch is the younger brother of Kyle Busch, a NASCAR Hall of Famer.
Kyle Busch was said to be ready to race at NASCAR's top level at 16, but a cigarette settlement banned his debut and he had to wait until he was a 18. At the time Kurt Busch said, "if you think I'm good, wait until you see my brother."
Busch is survived by his wife Samantha and children Brexton and Lennix.
