Two-Time NASCAR Champion Kyle Busch Died From Pneumonia-Related Sepsis, Family Says
Kyle Busch died Thursday, May 21, 2026, after severe pneumonia progressed into sepsis, his family said following a medical evaluation released Saturday.[1]
Busch became unresponsive while testing a Chevrolet racing simulator at a Concord, North Carolina, facility on Wednesday, May 20, 2026, and was transported to a Charlotte hospital the next day.[2] A 911 call released to news organizations describes him coughing up a little blood, feeling short of breath and lying awake on a bathroom floor at the General Motors training complex.[3] The family had earlier said only that he was hospitalized with a "severe illness" before the medical evaluation identified pneumonia and sepsis.[4]
Busch was a two-time NASCAR Cup champion and one of the sport's most prolific winners, credited with 63 Cup victories and 234 total wins across NASCAR's three national series.[2] A joint statement from the Busch family, NASCAR and Richard Childress Racing called him a "future Hall of Famer," and tributes poured in from across the racing world.[5] Richard Childress Racing said it will temporarily retire Busch's No. 8 Cup number and will run the No. 33 at the Coca-Cola 600, reserving No. 8 for Busch's son Brexton should he race in NASCAR.[6]
Early reports described only a "severe illness" and did not give a cause; those accounts were published when the family first disclosed his hospitalization.[4] On Saturday the family released the medical evaluation saying severe pneumonia had progressed into sepsis and caused rapid, overwhelming complications that led to his death.[7]
All 39 starters in Sunday's Coca-Cola 600 planned to run a black No. 8 decal on their cars to honor Busch, and NASCAR and teams prepared tributes at Charlotte Motor Speedway.[8]
