Team and driver changes

There were relatively few changes in the top teams, but no less than usual further down the order:

• The factory-backed Matra team had withdrawn from Formula One. They had already reduced their operations to one car before the 1972 season and, after the season, packed up all-together.
• With backing from Universal Oil Products and technical support from ex-BRM designer Tony Southgate, the Can-Am team Shadow Racing Cars entered the 1973 Formula One season. Shadow brought their Can-Am driver Jackie Oliver with them and signed 1972 Can-Am champion George Follmer. Finally, they sold a chassis to Graham Hill's new own team Embassy Racing.
• Lotus signed Ronnie Peterson from March.
• Hill had moved from Brabham, where Andrea de Adamich took his place. The Italian came from Surtees, where Carlos Pace found a new home.
• After Pace and Henri Pescarolo left, Frank Williams had to find two new drivers: Howden Ganley from BRM and Nanni Galli from Tecno. Tecno signed Matra's last driver, Chris Amon.^[2]
• BRM signed Clay Regazzoni^[3] and Niki Lauda, next to Jean-Pierre Beltoise. This was a golden trio of drivers, but they would only manage to gain twelve points and the team finished seventh in the Manufacturers' championship. A slight consolidation for Regazzoni, who had left Ferrari over the winter, was that the Italian squad finished just one place higher, on the same amount of points.
• After Peterson and Lauda had left March, they signed Jean-Pierre Jarier. He was due to drive for them in Formula Two, but was given a Formula One seat as well. His F1 season would turn out difficult, only classifying once during the year, but he managed to rack up the Formula Two title in dominant fashion.

Calendar changes

The calendar was expanded from 12 to 15 races:

• The Brazilian Grand Prix was held for the first time, at Autodromo de Interlagos, and the Swedish Grand Prix was held for the first time, at the Scandinavian Raceway in Anderstorp.
• The Dutch Grand Prix returned to the calendar after it had been cancelled in 1972 due to safety upgrades that were not completed in time. The upgrades included new asphalt, new barriers, a change in the circuit's layout and a new race control tower.

Other changes:

• The Belgian Grand Prix and Monaco Grand Prix swapped places on the calendar so that the Monaco round came second. The Belgian round also carried the unofficial title of European Grand Prix for 1973.^[10]
• The Spanish Grand Prix was moved from Jarama near Madrid to the Montjuïc street circuit in Barcelona, in keeping with the event-sharing arrangement between the two circuits. Likewise, the Belgian Grand Prix was moved from Nivelles-Baulers to Circuit Zolder, and the British Grand Prix was moved from Brands Hatch to Silverstone.
• The French Grand Prix was moved from Charade Circuit to Paul Ricard Circuit.

Technical regulations

• The minimum weight was increased from 550 kilograms (1,210 lb) to 575 kilograms (1,268 lb).^[11]

Sporting regulations

• Drivers would do a full warm-up lap before the race. Previously, they would form a dummy grid, a short distance behind an official grid, and the cars would simply move from one to the other to begin the race.
• The numbering system for teams was formalised:
  • From the second race of the season on, teammates were paired: the Lotus drivers were given 1 and 2, Tyrrell's drivers 3 and 4, and so on.^[12] The numbers assigned to each team did still change for a couple of races.
  • Ahead of the fifth race on the calendar, the order was set for the rest of the year.^[13]
  • And then for the 1974 season, the numbers were assigned based on finishing positions in the 1973 Manufacturers' championship. After this, teams did not change numbers, unless they won the Drivers' championship or signed the reigning Drivers' champion, or if they or another team dropped out of the competition.
• The 1973 season saw the intervention of a Safety Car in Formula One for the first time, in the form of a Porsche 914 at the Canadian Grand Prix.^[14] However, the concept of a safety car would not be officially introduced until twenty years later, in 1993.

Rounds 1 to 4

Like last year, the championship commenced in January in Argentina. Swiss driver Clay Regazzoni had left Ferrari after three years, having scored just one podium finish in 1972. He was attracted by the Marlboro-sponsored British Racing Motors team for "an astronomical fee"^[15] and delivered early success: he qualified on pole position, ahead of reigning champion Emerson Fittipaldi in the Lotus and last year's teammate Jacky Ickx. But on Sunday, it was sixth-starting François Cevert that took his rivals by surprise: he snatched the lead even before the first corner, before being passed by the pole sitter later in the lap. For the first quarter of the race, five drivers formed a tight leading pack: Regazzoni, Cevert, Fittipaldi, new Lotus driver Ronnie Peterson and 1971 champion Jackie Stewart. But then, with his Firestone tyres overheating, Regazzoni fell back to fifth, while Stewart's conservative start allowed him to get up to second place. Going into the tail end of the race, Fittipaldi overtook Stewart, much to the joy of the South American fans, and set a new lap record in his chase for Cevert. After 50 laps in the lead, the Frenchman had to surrender first position and eventually finished 5 seconds behind his Brazilian rival. Stewart came home in third.^[16]

After an inspired promotional campaign, São Paulo were selected to host the first ever World Championship Brazilian Grand Prix. Team Lotus dominated practice and qualified 1-2, but it was Peterson ahead of Fittipaldi. Ickx started next to them in third. The Tyrrells of Stewart and Cevert could only managed eighth and ninth, respectively. At the start, however, the Scot jumped up to third, behind Fittipaldi and another local hero with a good start, Carlos Pace. Peterson fell back to fourth and then, on lap 6, had a crash due to high right rear wheel collapsing. Pace then retired with suspension damage. Fittipaldi finished with a comfortable lead over Stewart. McLaren driver Denny Hulme was third.^[17]

Staying on the southern hemisphere but moving almost 7,500 km (4,700 mi) on, Kyalami hosted the South African Grand Prix. In practice, Jackie Stewart was going faster and faster until he suffered a dramatic brake failure and spun backwards through three layers of chain link fence. He was unhurt, so his biggest grief came from being unable to defend his time: with the first thirteen drivers separated by less than a second, the Scot was relegated to the sixteenth place on the grid. Denny Hulme achieved pole position, ahead of Emerson Fittipaldi and local driver Jody Scheckter. The start of the race was rather calm, but on lap 3, Clay Regazzoni crashed into a stationary Mike Hailwood. Both cars burst into flames and Regazzoni was unconscious. Hailwood did not hesitate to rescue him and managed to release the Swiss driver's seat belts. His overalls caught on fire, so he turned to a marshal with a fire extinguisher and then continued to drag Regazzoni from the wrecked BRM. Meanwhile, leader Hulme had to pit twice with punctures, but Stewart was performing a miraculous recovery drive: he was up to sixth place on lap 6, and was leading the race on lap 7. American driver Peter Revson in his McLaren overtook Fittipaldi for second place and managed to stay there. Scheckter retired with just four laps to go. At least three drivers reported Stewart for overtaking under yellow flags and McLaren's team boss filed the official protest. The stewards handed the Scot a severe reprimand but the race results were upheld.^[18]

The Spanish Grand Prix was held on Barcelona's street circuit that combined tight hairpins with high-speed blind corners, resulting in average speeds of over 160 km/h (99 mph). Peterson qualified on pole position, ahead of Hulme and Cevert. Stewart and Fittipaldi started fourth and seventh, respectively. Around a quarter distance, Hulme and Cevert had to pit with damage and the Swede at the front achieved a comfortable lead. On lap 55, however, his gearbox failed and his Lotus ground to a halt. Stewart retired with brake problems and Fittipaldi endured a slow puncture. Carlos Reutemann, smelling a sudden victory, was chasing down his fellow Brazilian until his driveshaft failed. So the championship leader held on to victory, ahead of François Cevert for Tyrrell and George Follmer in the Shadow.^[19]

In the Drivers' Championship, Emerson Fittipaldi (31 points) held a sizable lead over Jackie Stewart (19) and François Cevert (12). Lotus (31 points) was leading in the standings for the Manufacturers' Cup, ahead of Tyrrell (27) and McLaren (15).

Rounds 5 to 8

The Belgian Grand Prix was held at Circuit Zolder for the first time, as part of the 1972 agreement to alternate with Nivelles-Baulers. The track was prepared for the event too late and after an hour of practice, the drivers' union (GPDA) were threatening with a strike action, complaining that the tarmac was breaking up. After a quick resurfacing job on Friday evening, the track held together during Saturday practice, but now was very slippery, and there was a lot of sand off the racing line. Ronnie Peterson qualified his Lotus on pole position and held the lead at the start, but was passed by fourth-starting François Cevert (Tyrrell) on the second lap. Championship rivals Jackie Stewart (Tyrrell) and Emerson Fittipaldi (Lotus) had started in sixth and ninth, respectively, but quickly charged through the field. After Cevert spun off on lap 20 and rejoined down in eighth, they were fighting for the lead, with the Scot coming out on top. When Fittipaldi had to slow with fuel pressure problems, he had to settle for third, while Cevert recovered to second position.^[20]

The Monaco Grand Prix was held on a heavily revised circuit, the layout becoming even twistier and slower than before. Stewart qualified on pole position, ahead of Peterson, but it was Cevert who took the lead at the start. Clay Regazzoni moved his BRM ahead of Stewart, going up from eighth to third, and this became second when Cevert hit a kerbstone and punctured his tyre. On lap 6, however, he locked up coming out of the tunnel and had to make a pit stop. Now Stewart could start chasing down Peterson. When the Swede's Lotus started suffering from dropping fuel pressure, the lead was easily taken and Stewart steadily increased his lead. Fittipaldi got by his teammate for second position, but did not manage to put up a real fight with Stewart. The pair finished within 1.3 seconds of eachother, while they lapped the rest of the field, making abudantly clear that they would be the championship contenders for this year.^[21]

The F1 circus arrived at Anderstorp Raceway for the first Swedish Grand Prix and it was local hero Ronnie Peterson who qualified on pole position, ahead of François Cevert. Stewart and Fittipaldi started on the second row. At the start, Fittipaldi got up to second and so, the two Lotuses were leading the two Tyrrells. On lap 33, Stewart passed his teammate, who fell further back behind Denny Hulme in miscommunication with a lapped car. The McLaren driver was on a real charge and rejoiced in his rivals' troubles: Fittipaldi's brakes were fading before his gearbox packed up all together, Stewart lost drive and Peterson had worn out his tyres. Hulme won his first Grand Prix, ahead of Peterson and Cevert. Stewart was a lucky man finishing in fifth and salvaging two points for the championship.^[22]

Circuit Paul Ricard played host to the French Grand Prix, combining two twisty sections with the 1.8 km (1.1 mi) long Mistral Straight. Stewart qualified on pole, ahead of a surprising Jody Scheckter in just his third F1 race, and championship leader Fittipaldi. Scheckter made the quickest getaway and was followed by fifth-starting Peterson. Astonishingly, Scheckter led the field for 42 laps. While lapping a backmarker, however, the South African was hit from behind by now-second placed Fittipaldi. Both cars broke their left front suspension. Peterson picked up the scraps to take his first Grand Prix victory, ahead of Cevert and Reuteman. Stewart came home in fourth, scoring less points than usual, but important points nonetheless. ^[23]

In the Drivers' Championship, Jackie Stewart (42 points) had just overtaken Emerson Fittipaldi (41), while François Cevert was third (31). The Manufacturers' Cup was being fought just as closely by Lotus (52 points) and Tyrrell (51), ahead of McLaren (26) in a distant third.

Rounds 9 to 11

Going into the second half of the championship, the British Grand Prix was held at the fast Silverstone Circuit. The 450 bhp (340 kW) cars were expected to hit average speeds of nearly 225 km/h (140 mph). Fans and rivals were eager to see the pace of Jody Scheckter, after he was robbed of an apparent victory in France. The South African could manage a sixth starting place. Pole position was for Ronnie Peterson (Lotus), with Denny Hulme and Peter Revson (both McLarens) next to him. Championship rivals Jackie Stewart and Emerson Fittipaldi filled the second row of the grid. At the start, Stewart shot up to take the lead, ahead of Peterson and eighth-starting Reutemann. Going through Woodcote corner for the first time, Scheckter lost the back end of his McLaren, hit the pit wall and came to a halt in the middle of the track. Revson hit Scheckter's rear wing and another nine cars came together in a pile-up. The race was suspended (only the second time in history that had happened) while marshals extracated Andrea de Adamich from the wreckage with a broken ankle. Ninety minutes after the first start, the race got underway again and Peterson led from Lauda and Stewart. The Scot quickly got up to second and then tried his luck for first, but spun on the kerb. When Lauda made a pit stop, Fittipaldi was second, until he was hit with a transmission failure. During a short rain shower, Peterson lost the lead to Revson and the American managed to win his first Grand Prix. Hulme was third, ahead of future champion James Hunt in fourth.^[24]

Scuderia Ferrari had decided to withdraw from the Dutch Grand Prix to focus on upgrading their cars, seeing that they had played no part in the championship so far this year. Fittipaldi crashed during Saturday practice when his left front wheel broke coming on to the start-finish straight. His ankles were badly bruised. His teammate Peterson qualified on pole for the sixth time this season, ahead of Stewart and Cevert (Tyrrell). The top two remained the same at the start, but eighth-starting Carlos Pace took the place of Cevert in third. Fittipaldi had started the race but pitted on the second lap and was helped out of his car. On lap 8, Roger Williamson crashed his March at the same corner as Piers Courage in 1970. He was trapped in his overturned and burning car. With the crash taking place at the far end of the track, no one of the marshals understood this, instead mistaking David Purley, having abandoned his race to rescue Williamson, for the driver that had crashed, and they tried to drag him away. The race, meanwhile, continued and Peterson's lead grew ever bigger, until on lap 40, his engine was losing speed. He eventually retired on lap 66. Stewart took his fourth victory of the season ahead of Cevert and Hunt, the future champion's claiming his first podium finish. Local driver Gijs van Lennep finished sixth and scored a point as well.^[25]

The fearsome Nürburgring Nordschleife constituted the arena for the German Grand Prix. Stewart started on pole, ahead of Peterson and Cevert. Fittipaldi was down in fourteenth, still recovering from his injuries. Peterson retired half way through the first lap and the Tyrrells were unchallenged. Jacky Ickx was third for McLaren. Future champion Niki Lauda had crashed on the second lap, completely demolishing his BRM and breaking his wrist.^[26]

In the Drivers' Championship, Emerson Fittipaldi (42 points) had fallen down to third after a streak of four races without points. Jackie Stewart (60) was leading teammate François Cevert (45). Tyrrell (71 points) had also taken a firm grip on the Manufacturers' Cup over Lotus (59) and McLaren (42).

Rounds 12 to 15

Lotus were not giving up their hunt for the title: Emerson Fittipaldi and Ronnie Peterson qualified 1-2 for the Austrian Grand Prix. Their rivals at Tyrrell, Jackie Stewart and François Cevert, started seventh and tenth, respectively. Denny Hulme (McLaren) started third but overtook Fittipaldi before the first corner. On lap 4, Stewart overtook Arturo Merzario for fourth place. Cevert tried the same on lap 6, but hit the Ferrari and had to retire with a damaged wishbone. Hulme had to pit when he lost a cylinder. Fittipaldi was allowed to pass Peterson to keep his championship fight alive, but on lap 48, his engine suddenly died. His fuel line had come loose and it meant another retirement for the 1972 champion. Peterson won, ahead of Stewart and Pace.^[27]

If Stewart would manage to finish third or higher in the Italian Grand Prix, he would clinch the Drivers' Championship. A lower points finish would almost necessitate Fittipaldi to win and Cevert to get on the podium to stay in the championship fight. It was Peterson who claimed his seventh pole position of the season, ahead of the McLarens of Peter Revson and Denny Hulme. Stewart started in sixth, with his teammate and closest rival Cevert in eleventh. Fittipaldi started in fourth but was second before the first corner. Stewart got up to that vital fourth position, until he had to pit with a flat rear tyre. He rejoined in nineteenth, but by half distance, he was up in eighth place. With seven laps to go, he overtook his teammate for fourth position, so Fittipaldi would have to win the race. However, Peterson stayed ahead and Fittipaldi finished second ahead of Revson. Stewart was awarded the 1973 Drivers' Championship.^[28]

For the Canadian Grand Prix, Peterson started on pole, ahead of Revson and Scheckter. A heavy shower fell before the start and all-but-one drivers started on full wet tyres. After the start, Peterson was leading Scheckter and Lauda, while Revson fell back to seventh. Lauda was comfortable in the wet conditions and actually grabbed the lead on lap 4. Peterson crashed out on lap 16, before the track dried up and everyone started coming into the pits. The race organisers got confused with the order of the cars, even more when Scheckter and Cevert crashed and, as was agreed after the Dutch Grand Prix, the pace car was deployed. No one, however, knew for sure who was in the lead and the pace car driver picked up Howden Ganley as such. After ten laps, during which the track had completely dried, the field was released and Ganley hold off Stewart and Fittipaldi for eight laps. Post-race analysis showed that, actually, Jackie Oliver lost the lead on that lap to Peter Revson. Lotus team boss Colin Chapman believed Fittipaldi won after passing Ganley, but three hours after the race finished, Revson was declared the winner, with Fittipaldi in second and Oliver in third.^[29]

The 1973 season ended on a low-point when François Cevert crashed during practice for the United States Grand Prix and was killed on impact. Tyrrell withdrew from the event, giving up the Manufacturers' Title to Lotus. Peterson started on pole for the ninth time this year, ahead of Reutemann and Fittipaldi. Future champion Hunt in his little March passed Fittipaldi and Reutemann and came within a second of Peterson. The Swede held on to take his third win in four races, ahead of hero-of-the-day Hunt and Reutemann.^[30]

The Drivers' Championship was awarded to Jackie Stewart (Tyrrell, 71 points), ahead of Emerson Fittipaldi (Lotus, 55) and Ronnie Peterson (Lotus, 52). The Manufacturers' Cup was won by Lotus (92 points), ahead of Tyrrell (82) and McLaren (58).
