Kyle Busch has died at the age of 41 from severe pneumonia that progressed into sepsis, according to a statement from his family. The condition reportedly led to rapid and life-threatening complications. He was set to compete in the Coca-Cola 600 at Charlotte Motor Speedway just days later.
Sepsis is a dangerous reaction to infection that can cause organ failure, and in severe cases, can be fatal. Busch had reportedly been dealing with illness in the days leading up to his death, though it’s unclear if it was directly connected.
A two-time NASCAR Cup Series champion, Busch was one of the sport’s most successful and polarizing figures, known for his aggressive driving style, over 60 Cup wins, and a long career with top teams including Hendrick Motorsports and Joe Gibbs Racing.
