At the time of his death, Busch was in his 22nd full-time season in Nascar’s top division, where he had won two Cup Series titles and 63 races.
“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,” the statement said.
“His sharp wit and competitive spirit sparked a deep emotional connection with race fans of every age, creating the proud and loyal ‘Rowdy Nation.'”
Busch was scheduled to compete at the Coca-Cola 600 at Charlotte Motor Speedway over the upcoming holiday weekend in the United States.
Earlier on Thursday, Busch’s family said in a statement that he was in hospital due to a severe illness.
He was undergoing treatment, they said, and would not compete in any of his scheduled activities over the coming weekend.
The announcement of his death came hours later.
Busch is survived by his parents, his wife, and two young children.
