NASCAR Champion Kyle Busch Dies At 41
On Thursday, May 21, two-time NASCAR Cup Series champion Kyle Busch died at the age of 41. NASCAR confirmed the news in a statement, while the Busch family, Richard Childress Racing, and NASCAR also released a joint statement honoring the longtime driver.
Busch had been scheduled to compete in the Coca-Cola 600 at Charlotte Motor Speedway on Sunday, May 24. However, earlier that same day, his family announced that the two-time Cup Series champion had been hospitalized with what they described as a “severe illness” and would no longer participate in any racing activities.
The statement did not provide any additional details about Kyle Busch’s illness. However, his family released a statement on Saturday (May 23), revealing that he died due to complications related to “severe pneumonia [that] progressed into sepsis.”
“The medical evaluation provided to the Busch Family concluded that severe pneumonia progressed into sepsis, resulting in rapid and overwhelming associated complications,” FOX Sports’ Bob Pockrass reported.
Who Was Kyle Busch?
Kyle is survived by his wife, Samantha, and their two children Brexton (11) and Lennix (4). Busch was one of the most successful drivers in NASCAR history. Nicknamed “Rowdy,” Busch won two NASCAR Cup Series championships (in 2015 and 2019) and became known for his aggressive driving style and record-setting success across NASCAR’s top divisions.
Born in Las Vegas, Busch began racing as a teenager and quickly rose through the ranks. He debuted in NASCAR’s top series in 2004 with Hendrick Motorsports before becoming the face of Joe Gibbs Racing and Toyota’s NASCAR program for 15 seasons. In 2023, he joined Richard Childress Racing.
Busch held numerous NASCAR records, including the most combined wins across NASCAR’s three national touring series. He earned 63 Cup Series victories, more than 100 Xfinity Series wins, and nearly 70 Truck Series wins during his career.
We are saddened and heartbroken to share the news of the passing of Kyle Busch, a two-time Cup champion and one of our sport's greatest and fiercest drivers. He was 41 years old.

Medical Expert Explains The Danger With Sepsis
According to the Sepsis Alliance, sepsis, often called “blood poisoning,” is a “life-threatening emergency that happens when your body’s response to an infection damages vital organs.”
Dr. Todd Rice, a professor of medicine and director in the intensive care unit at Vanderbilt University Medical Center, explained to PEOPLE how pneumonia can develop into sepsis, and why the condition can become deadly so quickly.
“Pneumonia is one of the top causes of death for older people. Young people get pneumonia but usually they tolerate it pretty well,” Rice said. “But there are cases where with an infection, the body has a response to control the inflammation so it doesn’t get widespread. With sepsis, it kind of gets out of control.”
While Rice shared that the likelihood of a young person getting sepsis from pneumonia is “somewhat rare,” it’s not completely unheard of.
“Why do some people have this over-exuberant, uncontrolled inflammatory response that affects other parts of the body and other patients don’t? There are risk factors,” Rice explains.
When asked how Busch was racing and active up until the end of his life, Rice said that often times everything happens very quickly and individuals go downhill very fast.
“Young healthy people tend to tolerate infection pretty well. But when it gets really severe and they get really sick, we call it falling off the cliff. They are cruising along, maybe they don’t feel very well, but they’re doing okay. And then suddenly everything fails and they are in the ICU really sick and their blood pressure’s low and we can’t get it up and their kidneys don’t work and their lungs don’t work and they’re on a ventilator,” he continued.
Rice warns that anyone experiencing a fever multiple days on end or any shortness of breath and chest pain should see a medical professional to get checked out immediately. He reiterates that while it often impacts older individuals more severely, young people are not immune from sepsis and the complications that come with it.
“Young people do better than older people, but that doesn’t guarantee that you won’t die from it like Kyle Busch did.”
We are sending our thoughts and prayers to Kyle Busch’s family during this unimaginable time.
