Ned Jarrett, a two-time NASCAR Cup Series champion and longtime broadcaster, died Thursday of natural causes in his home, his family said in a statement shared by the racing organization.

Formula 1 is to race in Las Vegas until at least 2037 after extending its contract with the city by 10 years.

Jarrett, a NASCAR Hall of Famer, won 50 Cup Series races across 352 starts from 1953 through 1966.
