1957 Formula One season

The first race of the season was in January at the Buenos Aires Autodrome in Argentina's capital city. Briton Moss took pole ahead of Fangio, ahead of Behra, and Ferrari drivers Castellotti, Collins, Musso and Hawthorn. At the start of the race Behra took the lead from Fangio and Castellotti. Moss was taken by surprise and a juddering start damaged the throttle mechanism and he pitted at the end of the first lap. While Moss sat in the pits, Castellotti led but was then overtaken by Behra. Soon afterwards Collins worked his way to the front but within a few laps he was in trouble with his clutch and had to pit. This left Behra in the lead again but he was soon passed by Fangio. Castelotti had lost his third position after a spin, so now Hawthorn was leading the charge although both he and Musso would retire after a while with clutch problems. Castellotti remained the only challenge to the Maseratis at the front but his race ended when a wheel fell off with 24 laps to go. Menditeguy and Schell were promoted to third and fourth when Castellotti went out and so Maserati started the season by romping home with a 1-2-3-4 result, with Fangio winning his 4th Argentine Grand Prix in a row ahead of Behra.

Argentina '57 would be Castellotti's last Grand Prix. He was killed testing a Ferrari at the Modena Aerodrome in March. A non-championship race was held in Syracuse on the southern Italian island of Sicily; this race was won by Peter Collins for Ferrari. The Pau Grand Prix, held on the city streets of the southwestern French town of Pau was won by home favorite Behra in a Maserati, while on the same day, the Glover Trophy at the Goodwood circuit in southern England was won by Briton Stuart Lewis-Evans in a Connaught-Alta. 6 days after these two events, Collins won the Naples Grand Prix. Another works Ferrari driver, Spaniard Alfonso de Portago, was killed in May while contesting the Mille Miglia sportscar race in Italy for Ferrari.

Four months after the Argentine round and a number of non-championship races, the teams assembled in Monaco for the second championship round of the season. Moss had joined Vanwall from Maserati, driving a car designed by Colin Chapman and financed by Tony Vanderwell, a wealthy British industrialist, leaving Fangio as the undisputed team leader at Maserati. Fangio took pole position, however Moss took the lead at the first corner with Fangio behind him but on the second lap Collins got ahead of the Argentine driver. Moss went off and crashed at the chicane on lap 4, and Collins swerved to avoid the crash and ended up hitting a stone wall. Fangio managed to get through without a problem and Brooks braked hard only to be rammed from behind by Hawthorn. Only Brooks was able to keep going, but he was five seconds behind Fangio by the time he was up to speed again. Von Trips was third with Menditeguy fourth and Schell fifth. Menditeguy would have to stop early for new tyres after hitting a curb so Schell moved to fourth until his suspension broke. Brabham was next in the little Cooper with Trintignant chasing him but the Frenchman soon dropped away with a stop to cure a misfire. After a number or retirements, Australian Jack Brabham was up to third as a result of this but a fuel pump failure left him to push the car to the line. He was classified sixth, and Fangio won again ahead of Brooks, Masten Gregory in a Maserati, Lewis-Evans and Trintignant.

The Indianapolis 500 was the 3rd round of the championship but since that race was not run to Formula One rules, no competitors who raced in Formula One raced at the Indy 500, and vice versa. The Belgian and Dutch Grands Prix, which had been scheduled for June 2 and June 16, were both canceled because of disputes over money affected by the Suez crisis in Egypt, so there was a six-week break between Monaco and the French GP, which was to be held at the Rouen-Les-Essarts public road circuit in northern France, extended from its previous layout used in 1952.

In practice Fangio was fastest with Behra and Musso alongside on the front row. Behind them were Schell and Collins with the third row consisting of Salvadori, Hawthorn and Trintignant. At the start Behra went into the lead but Musso soon got ahead. Fangio followed in third with Collins and Schell giving chase. Then came a fast-starting McKay-Fraser. Fangio worked his way past Behra on the second lap and took Musso for the lead on lap four. BRM suffered a setback when Flockhart seriously damaged his car in a high-speed accident, although he himself was not hurt. Collins worked his way past Behra and the order remained unchanged at the front all the way to the flag with Fangio winning from Musso and Collins. Behra slipped behind Hawthorn, allowing the Englishman to give the Lancia-Ferraris a 2-3-4 finish behind Fangio. McKay-Fraser's promising run ended with a transmission failure at one-third distance but the American would not be seen again in F1. He was to die a few days later in the annual Formula 2 race at the Reims public road circuit before the Reims Grand Prix, which was won by Musso in a Lancia-Ferrari.

The British Grand Prix was held at the Aintree circuit in Liverpool as opposed to being held at the Silverstone circuit between London and Birmingham the previous year. The Aintree circuit was located in the middle of the horse-racing course where the famous Grand National was held. Both Vanwall drivers missed the French Grand Prix, and were back in action for their home race. This was to be a landmark race for British motorsports. At the start of the race, Behra took off into the lead with Moss in hot pursuit and it was the Englishman who emerged ahead at the end of the lap, to the delight of the partisan crowd. Brooks was third with Hawthorn fourth and Collins fifth. There were four British drivers in the top five positions. Then came Schell, Musso and Fangio. Moss was able to build up his lead but then the car began to sound rough and he pitted. Behra took the lead with Brooks behind him but the second Vanwall driver was soon called into the pits to give his car to Moss who rejoined in ninth position. He began to work his way through the field. Behra remained ahead with Hawthorn unable to challenge him. Then came Lewis-Evans and Collins. Moss was quickly back up to fifth. The field was thinned out by a series of mechanical failures including Fangio and Collins. Moss caught Lewis-Evans but then on lap 69 the whole race changed when Behra's clutch exploded. Hawthorn ran over some of the wreckage and suffered a puncture. Lewis-Evans took the lead but was passed almost immediately by Moss. The dream of a Vanwall 1–2 was punctured when Lewis-Evans suffered a broken throttle linkage which dropped him to seventh place. Moss duly won the race, claiming the first World Championship victory for a British car. Musso was second with Hawthorn third.

The Caen Grand Prix, another important non-championship Formula One race held in the town of Caen in northern France (further west of Rouen), held between the British and German Grands Prix was won by Behra in a BRM.

At the Nürburgring in Germany the field was as normal with Lancia-Ferrari fielding Mike Hawthorn, Peter Collins and Luigi Musso and Maserati running Juan Manuel Fangio, Jean Behra and Harry Schell in their leading cars. The field was bolstered for the first time by Formula 2 machinery which included a trio of Porsches and various Cooper-Climaxes; the length of the circuit allowed for these cars to run alongside each other.

Pole position went to Fangio with Hawthorn, Behra and Collins completing the front row. Then came Brooks, Schell and Moss. At the start Hawthorn and Collins went into a battle for the lead with Fangio and Behra giving chase. On the third lap Fangio passed Collins and was soon able to take the lead. Collins then passed Hawthorn and chased after Fangio but the Argentine driver was edging gradually away. A slow mid-race pit stop lasting 1 minute and 18 seconds (originally supposed to be 30 seconds) dropped Fangio one whole minute behind the two Lancia-Ferraris but he chased back hard, broke the lap record 10 times and passed both first Collins and then Hawthorn on the penultimate lap. Fangio thus won the race and his fifth World title.

The cancellation of the Belgian and Dutch GPs earlier in the season enabled the FIA to include the Coppa Acerbo Pescara GP in the World Championship for the first time, although it had been taking place since 1924– it was around during the 1930s Grand Prix days of Mercedes, Auto Union and Alfa Romeo, and was continued to be used as a non-championship race throughout the 1950s. The 25.6 km public road circuit, the longest ever used for a Formula One race (even longer than the Nürburgring), was very dangerous. Practice was limited and Enzo Ferrari did not bother to send cars for Mike Hawthorn and Peter Collins, partly because the World Championship had already been won by Juan Manuel Fangio and partly in protest against Italian government moves to ban road racing, following Alfonso de Portago's accident earlier in the year in the Mille Miglia. Luigi Musso managed to convince Ferrari to lend him a car and entered the race as a privateer.

Maserati's Fangio set the fastest time in qualifying with Stirling Moss second in his Vanwall. Musso was third. The second row of the 3–2–3 grid featured the Maseratis of Jean Behra and Harry Schell while row three had Vanwall's Tony Brooks and Stuart Lewis-Evans split by the Scuderia Centro Sud Maserati of Masten Gregory.

The weather was hot and at the start, Musso took the lead. Maserati privateer Horace Gould hit a mechanic who was slow to get off the grid. Vanwall's challenge was blunted on the first lap when Brooks retired with mechanical troubles. Moss took the lead from Musso on lap two but the two cars remained together. Fangio ran third but the field thinned out quickly as the hot temperatures took their toll with Lewis-Evans losing nearly a lap because of two tyre failures and Behra suffering an engine failure. On lap 10, Musso disappeared when his engine blew, the oil causing Fangio to have a spin which damaged one of his wheels. By the time Fangio rejoined, Moss was un-catchable. Moss's lead was even able to stop for a drink and to have his oil topped up, and he won the race ahead of Fangio. Schell finished third with Gregory fourth and Lewis-Evans grabbing fifth at the end of the race from the fourth Maserati factory driver Giorgio Scarlatti. The Coppa Acerbo was never again to be used for a Formula One championship race; the race was last held in 1961 as a sportscar race.

The Italian Grand Prix at Monza was held only on the road circuit without the poorly constructed concrete banking this year, as it had caused problems for the Italian constructors the year before. The track used was very like the Monza of today, although without the chicanes. Ferrari was back in action for this most important of Italian races after boycotting Pescara and so it was a three-way fight between the Lancia-Ferraris, the Maseratis and the Vanwalls. The British cars were strong with pole position going to Stuart Lewis-Evans with Stirling Moss and Tony Brooks alongside him. Juan Manuel Fangio put his Maserati on the outside of the 4-3-4 grid while his teammates Jean Behra and Harry Schell shared row two with Peter Collins's Lancia-Ferrari. There were three more of the cars on row three with Wolfgang von Trips, Luigi Musso and Mike Hawthorn alongside the Scuderia Centro Sud Maserati of Masten Gregory.

Although the Vanwalls went away from the grid at the front Behra moved up to second on the first lap. Fangio attached himself to the train of cars ahead of him and the five began to pull away from the rest of the field while indulging in a traditional Monza slipstreaming battle which saw the lead constantly changing between Moss and Behra. On lap seven Fangio took the lead but he was soon toppled in favor of Moss, Brooks and then Lewis-Evans. On lap 20 Brooks dropped out of the fight with a sticking throttle. Then Lewis-Evans ran into trouble and pitted. This left Moss in the lead with Fangio and Behra behind him, although Behra would pit soon afterwards for new tyres. This moved Schell into third place but he disappeared with an oil leak which meant that third was passed on to Collins. At two-thirds distance Collins ran into engine trouble and pitted. This promoted Hawthorn to third but a split fuel pipe dropped him to sixth in the closing laps, leaving third place to Von Trips.

3 more non-championship races were held, all of which were won by Jean Behra. The BRDC International Trophy at Silverstone in England, won driving a BRM; the Modena Grand Prix at the Modena Aerodrome (where Eugenio Castellotti had been killed previously) and the Moroccan Grand Prix at the Ain-Diab public road circuit in Casablanca, both won in a Maserati.

All 7 of the FIA-mandated championship races had been won by 2 drivers in 1957: Argentine Juan Manuel Fangio and Briton Stirling Moss. Although Moss took over an ill Tony Brooks's car during the British Grand Prix, he won with it on the road at that event.
