Kyle Busch, a two-time Cup Series champion who won more races than anyone across NASCAR’s three national series, has died. He was 41. The Busch Family, Richard Childress Racing and NASCAR issued a joint statement Thursday saying Busch died after being hospitalized. No cause of death was given. Busch’s family said earlier Thursday that he was hospitalized with a “severe illness,” three days before he was to compete in the Coca-Cola 600 at Charlotte Motor Speedway.
