Nascar driver Kyle Busch died from sepsis after severe pneumonia led to rapid and overwhelming complications, according to a statement released by his family on Saturday. The two-time Nascar champion passed away on Thursday at the age of 41, a day after collapsing in a Chevrolet simulator while preparing for the Coca-Cola 600 at Charlotte Motor Speedway.
Busch was transported to a hospital in Charlotte, North Carolina, where he later died. A 911 call obtained by the Associated Press revealed that the driver experienced shortness of breath, felt overheated, and was coughing up blood the day before his death. An unidentified caller told dispatch that Busch was lying on a bathroom floor but was conscious.
Busch’s death has sent shockwaves through the motor racing community. Over his two-decade career, he won 234 races across Nascar’s top three series, more than any driver in history. Tributes poured in from figures including former President Donald Trump, who called Busch “a true talent who loved NASCAR and its fans,” and Vice-President JD Vance, who described him as “one of NASCAR’s greatest racers.”
Nascar CEO Steve O’Donnell called Busch “an American badass” and lamented the loss of their battles. All 39 drivers in Sunday’s race will carry a black No 8 decal in his honour. Fellow driver Brad Keselowski noted he had been aware Busch was unwell but his recent Truck Series win had allayed concerns.
Sepsis is a life-threatening condition where the body’s immune response to an infection damages its own tissues and organs. The Centers for Disease Control and Prevention warning highlights that sepsis can cause widespread inflammation and blood clots, leading to organ failure.
