Former Formula One world champion John Surtees has died at the age of 83.
A statement on the Henry Surtees Foundation Facebook page (h/t Luke Smith of NBC Sports) confirmed the legend, who also won motorcycling honours, had passed away.
The family of the British star's statement read:
It is with great sadness that we announce the death of our husband and father, John Surtees CBE.
John, 83, was admitted to St Georges Hospital, London in February with an existing respiratory condition and after a short period in intensive care he passed away peacefully this afternoon. His wife, Jane and daughters, Leonora and Edwina were by his side.
John was a loving husband, father, brother and friend. He was also one of the true greats of motorsport and continued to work tirelessly up until recently with The Henry Surtees Foundation and Buckmore Park Kart Circuit.
The Brit drove for Ferarri and captured the Formula One title in 1964.
Earlier in his career, Surtees won the 500cc motorcycle world championship in 1956, 1958, 1959 and 1960. He is the only individual to win world crowns in both motorcycling and car racing.
Surtees' achievements are unlikely to be repeated as drivers do not cross the threshold between bikes and cars at the top of the sport in modern-day racing.
