1973 Formula One season

The 1973 Formula One season included the 24th FIA Formula One World Championship season, which commenced on January 28, 1973, and ended on October 7 after fifteen races.

Season summary
In 1973, Lotus teammates Fittipaldi and Ronnie Peterson raced each other while Stewart was supported by François Cevert at Tyrrell. Stewart took the Driver's title, but then at the final race of the season, the United States Grand Prix at Watkins Glen, Cevert crashed during Saturday practice in the notorious 'Esses' and was killed instantly. Stewart and Tyrrell withdrew from the race effectively handing the Constructor's title to Lotus. At the end of the season Stewart made public his decision to retire, a decision that was already made before the US Grand Prix.

By the end of 1973 season the best car on the track was probably the new McLaren M23, a wedge-shaped car following the same concept as the Lotus 72 but with more conventional suspension and up to date aerodynamics.
