The FIA introduces in 1973 the deployment of a formation lap before the entries line up on the grid for the race start, as well as an entry numbering system that affixes the same number to a given entry for the entire racing season. In one of the most perilous and tragic seasons in Formula 1 history, the tragic departure of Tyrrell François Cevert during practice at Watkins Glen in October prompts the constructor to withdraw from the event and cede the constructors' honors to Lotus, which takes its second consecutive title, yet Tyrrell still amasses enough points over the season to secure the putative laurels. Tyrrell driver Jackie Stewart seals his third drivers' crown and ascends as the all-time career leader with 26 victories, supplanting the great Jim Clark, yet the sudden passing of Cevert prompts the Scotsman to promptly retire from auto racing. F1 makes its inaugural visit to Interlagos, São Paulo in February. Driver Mike Hailwood in dramatic fashion saves the life of fellow pilot Clay Regazzoni from his fiery shunt at Kyalami in March. LEC driver David Purley unfortunately cannot prevent the same fate for March pilot Roger Williamson after his shunt leaves him trapped in his flaming entry at Zandvoort in July. F1 makes its inaugural visit to Zolder in May. Future F1 champion James Hunt makes his debut at Monaco in June. F1 makes its inaugural visit to Anderstorp, Sweden in June. The inexperience with using a Safety Car by the FIA leads to a confusing result at Watkins Glen in September, requiring race officials to sort out the lap sheets before declaring McLaren driver Peter Revson as the race winner. Revson still stands as the last American-born driver to win an F1 contest. Departures: Roger Williamson, 25, b. Ashby-de-la Zouch, England 1948, d. F1 Dutch GP, Zandvoort, The Netherlands, July. A. François Cevert Goldenberg, 29, b. Paris, France 1944, d. at practice, F1 US GP, Watkins Glen, New York USA, October. New Racing Makes: Italian Iso. British Ensign.

HeM applies the Putative Model to all racing seasons for two primary purposes: First, to effectively normalize all racing seasons for empirical comparison across the decades, and second, to step clear of series organizers which score season championships primarily out of commercial interest or to attract manufacturer participation. The Putative Model simply scores all seasons in the same fashion as a standard track and field meeting, with the only purpose of tracking what takes place at the finishing stripe If the Putative Champion differs from the nominal Series Champion, please note the (SC) notation below.

Noteworthy 1973 Races

1973 XXXI Grand Prix de Monaco Monte Carlo1973 1973 XXXI Grand Prix de Monaco At Monaco for the Grand Prix (256 kilometers) in June, a British Tyrrell 006 Ford under Jackie Stewart (GB) takes race honors in 1:57:44.3 (average 80.90 mph), under two seconds ahead of a Lotus driven by Emerson Fittipaldi. Stewart moves out front on Lap 8 of 78 after race leader Ronnie Peterson in his Lotus suffers fuel pickup problems before deftly holding off Fittipaldi by a slender margin at the wire. Stewart wins at Monte Carlo for the second consecutive season and the third time overall at Monte Carlo while snaring his twenty-fifth career Formula 1 victory, matching his fellow Scot and close friend Jim Clark.

1973 IV Grand Prix of Sweden Anderstorp, Sweden1973 1973 IV Grand Prix of Sweden At the Scandinavian circuit for the Swedish Grand Prix (321.5 kilometers) in June, a British McLaren M23 Ford under Denis Hulme (NZ) takes race honors in 1:56:46.1 (average 106.20 mph), under five seconds ahead of a Lotus driven by home favorite Ronnie Peterson. Hulme moves to the front after faltering race leader Peterson drops a tire with only two laps remaining, greatly disappointing the home crowd. Photo Credit: Ford Motor Company.
1973 French Grand Prix Le Castellet, France1973 1973 French Grand Prix At Paul Ricard for the French Grand Prix (314 kilometers) in July, a British Lotus 72E Ford under Ronnie Peterson (SE) notches a victory in 1:41:36.5 (average 115.12 mph), under forty-one seconds ahead of a Tyrell entry. Peterson, after allowing swifter Jody Scheckter in his McLaren through to take his shot at race leader Emerson Fittipaldi in his Lotus, takes full advantage after Fittipaldi and Scheckter tangle at the Bridge Curve with only twelve laps remaining. Peterson snares his maiden Formula 1 victory and avenges his bitter failure at Anderstorp as a very angry Fittipaldi and the McLaren team exchange words after the finish.

1973 British Grand Prix Silverstone, England1973 1973 British Grand Prix At Silverstone for the British Grand Prix (315.5 kilometers) in July, a British McLaren M23 Ford under Peter Revson (US) bests the field in 1:29:18.5 (average 131.76 mph), under three seconds ahead of a Lotus driven by Ronnie Peterson. An eight-car shunt on Lap 1 prompts a race restart, the first instance of the same in Formula 1 history. Revson moves out front past race leader Peterson on Lap 39, earns his maiden F1 victory, and becomes only the fourth American (P. Hill, Gurney, Andretti) to win a major Grand Prix event in the modern era. Race marshals require an hour to extract driver Andrea de Adamich from his Brabham after the Lap 1 shunt.

1973 XXI Grote Prijs van Nederland Zandvoort, The Netherlands1973 1973 XXI Grote Prijs van Nederland At Zandvoort for the Dutch Grand Prix (304 kilometers) in July, a British Tyrrell 006 Ford under Jackie Stewart (GB) crosses first in 1:39:12.5 (average 114.40 mph), under sixteen seconds ahead of a companion Tyrrell entry. Stewart moves out front after race leader Ronnie Peterson in his Lotus suffers gearbox failure with only nine laps remaining. Stewart ascends atop the F1 career drivers’ table with twenty-six victories (Clark), yet the race claims the life of Roger Williamson, starting only his second Formula 1 contest, who perishes after his entry hits a guardrail on Lap 8 and bursts into flames. Driver David Purley desperately attempts to rescue Williamson to no avail, and both FOCA and the drivers bitterly complain afterwards about the delay in rescuing Williamson as well as the decision not to halt the contest.

1973 Austrian Grand Prix Spielberg, Austria1973 1973 Austrian Grand Prix At the Österreichring for the Austrian Grand Prix (319.5 kilometers) on a scorching day in August, a British Lotus 72E Ford under Ronnie Peterson (SE) wins in 1:28:48.78 (average 134.01 mph), under ten seconds ahead of a Tyrrell driven by Jackie Stewart. Peterson moves out front after race leader Emerson Fittipaldi in his Lotus drops a fuel line only five laps from the finish. Photo Credit: Cahier Archive.
1973 VIII Race of Champions West Kingsdown, England1973 1973 VIII Race of Champions At Brands Hatch for the Race of Champions (170.5 kilometers, non-championship) in March, the race comes to a Formula 5000 British Chevron B24 Chevrolet under Peter Gethin (GB) in 0:57:22.9 (average 110.35 mph), under four seconds ahead of a McLaren driven by Denis Hulme. A calamity of shunts and mechanical failures leaves Gethin in position in the closing laps, who then moves out front on the final circuit after race leader Hulme drops a clutch bearing, gifting Gethin with a wondrous upset victory with his F5000 entry over the F1 racing set.

1973 XXV BRDC International Trophy Silverstone, England1973 1973 XXV BRDC International Trophy At Silverstone for the BRDC International Trophy race (188.5 kilometers, non-championship) in April, a Tyrrell 006 Ford under Jackie Stewart (GB) takes race honors in 0:52:53.2 (average 132.83 mph), under eleven seconds ahead of a Lotus driven by Ronnie Peterson. Stewart runs down race leader Peterson on Lap 2 only to spin out at Becketts a few laps later and drop back to sixth position. Undeterred, Stewart resumes the chase and closes in on Peterson just as snow flurries begin to fall upon the circuit. With both drivers pressing hard in the treacherous conditions, Stewart manages to slip past Peterson before both entries slide off the slick circuit. Stewart recovers first, continues his press through the flurries, and crosses for a dramatic victory in the most unanticipated of race conditions. Photo Credit: Attribution Unascertained.
