The 1973 Formula One season was the 27th season of FIA Formula One motor racing. It featured the 1973 World Championship of Drivers and the 1973 International Cup for F1 Manufacturers, which were contested concurrently over a fifteen-race series[1] that commenced on 28 January and ended on 7 October. The season also included two non-championship races which were open to both Formula One and Formula 5000 cars.
The World Championship of Drivers was won by Jackie Stewart, driving for Elf Team Tyrrell, for the third time. The International Cup for F1 Manufacturers was awarded to John Player Team Lotus.[1] At the final race of the season, Stewart's teammate Francois Cevert crashed during Saturday practice and was killed instantly. The Tyrrell team withdrew from the race, handing the Manufacturers' title to Lotus. Subsequently, Stewart made public his decision to retire, but he had decided on this already earlier.
British driver Roger Williamson was also killed during the season, in a tragic crash at the Dutch Grand Prix where marshals arrived too late on the scene and fellow driver David Purley was unable to free Williamson from the burning wreck.
