Alfa Romeo in Formula One
Italian motor manufacturer Alfa Romeo has participated many times in Formula One. It currently participates as Alfa Romeo F1 Team Stake while being operated by Sauber Motorsport AG. The brand has competed in motor racing as both a constructor and engine supplier sporadically between  and , and later as a commercial partner since . The company's works drivers won the first two World Drivers' Championships in the pre-war Alfetta: Nino Farina in 1950 and Juan Manuel Fangio in . Following these successes, Alfa Romeo withdrew from Formula One.

During the 1960s, although the company had no official presence in the top tier of motorsport, several Formula One teams used independently developed Alfa Romeo engines to power their cars. In the early 1970s, Alfa provided Formula One support for their works driver Andrea de Adamich, supplying adapted versions of their 3-litre V8 engine from the Alfa Romeo Tipo 33/3 sports car to power Adamich's McLaren () and March () entries. None of these engine combinations scored championship points.

In the mid-1970s, Alfa engineer Carlo Chiti designed a flat-12 engine to replace the T33 V8, which achieved some success in taking the 1975 World Sportscar Championship. Bernie Ecclestone, then owner of the Brabham Formula One team, persuaded Alfa Romeo to supply this engine free for the 1976 Formula One season. Although the Brabham-Alfa Romeo's first season was relatively modest, during the  and  World Championships their cars took 14 podium finishes, including two race victories for Niki Lauda.

The company's sporting department, Autodelta, returned as the works team in . This second period as a constructor was less successful than the first.  Between the company's return and its withdrawal as a constructor at the end of , Alfa works drivers did not win a race and the team never finished higher than sixth in the World Constructors' Championship. The team's engines were also supplied to Osella from  to 1987, but they scored only two World Championship points during this period.

The Alfa Romeo logo returned to Formula One in 2015, appearing on the Scuderia Ferrari cars. In late 2017, Alfa Romeo announced that they were to become title sponsors for Sauber from , and had entered into a technical and commercial partnership with the team. Alfa Romeo returned to the sport when Sauber was renamed at the beginning of .

As a constructor

Pre-Formula One era: early success and Grands Prix winning (1920s–1940s) 

Before World War II, Alfa Romeo was a dominant presence in Grand Prix motor racing. The P2 and the P3 consistently achieved victories until 1934, when the German Mercedes and Auto Union cars emerged and posed serious competition. By this time, Alfa Romeo had withdrawn temporarily as a manufacturer and was run by Enzo Ferrari and his Scuderia Ferrari team from 1929 to 1938. From 1934 to the start of World War II in 1939, Alfa rarely experienced a scarcity of victories, as their cars appeared underdeveloped compared to the technically advanced Mercedes.

After Alfa Corse retrieved its control of the brand from Ferrari, they made the Alfa Romeo 158 for the 1938 season. The 158, after subsequent updates, went on to become a dominant force in Gran Prix racing in the aftermath of the war. Alfa continued to use this car at Grands Prix from 1946 to 1948, withdrawing from racing in 1949 due to death of Jean-Pierre Wimille, Achille Varzi, and Carlo Felice Trossi, dominating the 1947 and 1948 Grand Prix seasons.

The success at the dawn of Formula One and retirement (1950–1951) 

Alfa Romeo experienced astounding success in the first two seasons of the Formula One World Championship. In 1950, Giuseppe Farina won the inaugural World Drivers' Championship in a 158 with a supercharger. The success was replicated the following year by Juan Manuel Fangio while driving an Alfetta 159 (an evolution of the 158 with a two-stage compressor). The Alfetta's engines were extremely powerful for their capacity: in 1951 the 159 engine was producing around  but this was at the price of fuel consumption of 125 to 175 litres per 100 km (1.5 mpg–U.S. / 3 mpg–imp).

Surprisingly, the team won the two World Drivers' Championships on a very limited budget, using only nine engine blocks that were built before the war. In 1952, facing increased competition from Ferrari, the Istituto per la Ricostruzione Industriale, a public holding company controlling Alfa Romeo, decided to withdraw the team from Formula One after the Italian government's refusal to fund the expensive design of a new car to replace the 13-year-old model.

Second spell as a constructor (1979–1985) 

In 1976, Alfa Romeo started supplying engines to Brabham, winning two Grands Prix during the 1978 Formula One season. However, in 1977, Italian engine designer Carlo Chiti persuaded the team to develop their own Formula One car. The development, led by Alfa Romeo's competition department Autodelta, started in 1977. The result was the Alfa Romeo 177, which made its debut at the 1979 Belgian Grand Prix.  The partnership with Brabham finished before the end of the 1979 season, with Brabham switching back to Cosworth DFV engines.

This second spell in Formula One was never truly successful and their performance was consistently hampered by reliability issue. In , they endured endured tragedy when their driver Patrick Depailler died in a fatal crash while testing for the 1980 German Grand Prix at the Hockenheimring. At the 1980 United States Grand Prix, Bruno Giacomelli obtained pole position with the Alfa Romeo 179, and led the race for 32 laps before the Alfa coasted to a halt with electrical trouble. 

In , the team's best achievement that year was Giacomelli's third-place finish at the 1981 Caesars Palace Grand Prix with an Alfa Romeo 179C. After a restructuring of Autodelta, the team operations and design of the car were outsourced to Euroracing in , with the engines still being supplied by Autodelta. This year, the team achieved a pole position at the 1982 United States Grand Prix West and a third-place finish at the 1982 Monaco Grand Prix, both with Andrea De Cesaris driving the Alfa Romeo 182. The team's best season was , when the team switched to the turbocharged 890T V8 engine and achieved the sixth place in the Constructors' Championship, largely thanks to two second-place finishes by Andrea de Cesaris with the Alfa Romeo 183T.

While the turbocharged 890T had proved somewhat competitive in 1983, increasing competition from more powerful engines from BWM and TAG, plus the fact that FIA imposed 220-litre fuel limit with no re-fuelling allowed during pit stops during  saw the decline of the Euroracing Alfa Romeo team as a competitive force in Grand Prix racing. The 890T (the only turbo V8 engine used in GP racing at this time) was very thirsty, and to temporarily rectify this problem, the drivers could interact with a knob regulating the turbo pressure, thus reducing the available power. Riccardo Patrese's third-place finish at the 1984 Italian Grand Prix being the last podium finish for the team, with both Patrese and Eddie Cheever often failing to finish races throughout 1984 and  due to running out of fuel.

The team's 1985 car, the Alfa Romeo 185T, proved to be so uncompetitive that the 1984 car, the 184T, was re-called into service mid-season. After being updated to 1985 specifications the car, now dubbed the 184TB, was an improvement over the 1985 car, but results were still not forthcoming. In an interview he gave years later, Riccardo Patrese described the 185T as the worst car he had ever driven.

Alfa Romeo pulled out of Formula One as a constructor at the end of the 1985 season.

The partnership with Sauber (2019–2023)

On 1 February 2019, following the multi-year technical and commercial partnership agreement established in 2018, Sauber announced that the team would rename to Alfa Romeo Racing, while the ownership, Swiss racing licence, and management structure would remain unchanged.

Alfa Romeo's challenger for the  season was the C38, continuing the naming convention from previous Sauber Formula One cars. The C38 included unique aerodynamic design elements in comparison to its rivals and predecessors, particularly at the front of the car as a result of regulation changes for the new season. 2007 world champion Kimi Räikkönen and former Sauber reserve driver Antonio Giovinazzi were hired as the team's drivers. Giovinazzi led the 2019 Singapore Grand Prix for four laps, the first Alfa Romeo driver to lead a lap since Andrea de Cesaris did so at the 1983 Belgian Grand Prix. The team's best result of the year came at the chaotic Brazilian Grand Prix, where Räikkönen and Giovinazzi were classified 4th and 5th respectively. Alfa Romeo finished the year in 8th place in the Constructors' Championship with 57 points.

Alfa Romeo entered the  season with an unchanged driver lineup. In January 2020, the team announced that they would enter a title sponsorship arrangement with Polish oil company PKN Orlen (renaming the team as Alfa Romeo Racing Orlen in 2020 and 2021 and as Alfa Romeo F1 Team Orlen in 2022) and that Robert Kubica would join as a reserve driver. Alfa Romeo finished the 2020 season in 8th place again, but this time scoring only 8 points.

In July 2021, Alfa Romeo Racing extended their deal with Sauber with a multi-year agreement with yearly assessments. In the 2021 season, the team finished in 9th place with 13 points. At the end of the season, Räikkönen retired from Formula One, while Giovinazzi departed the team to compete in Formula E.

For the  season, the team signed former Mercedes driver Valtteri Bottas and Formula 2 graduate Zhou Guanyu, securing their best Constructors’ Championship finish in 6th place since the beginning of their partnership with Sauber. 

In January 2023, Alfa Romeo announced a multi-year title sponsorship agreement with online casino Stake, renaming the team as Alfa Romeo F1 Team Stake and having their logo displayed prominently on the C43. The team also signed a partnership agreement with live streaming platform Kick, which is invested by Stake co-founder and owner Eddie Craven. Kick's name and logo will replace Stake's in countries where gambling and sports betting advertisements are not allowed as Alfa Romeo F1 Team Kick. Alfa Romeo raced a revised Kick livery at the 2023 Belgian Grand Prix. 

Alfa Romeo are due to pull out of Formula One at the end of 2023 and ending their partnership with Sauber, who are set to launch a works partnership with Audi in 2026.

As an engine supplier

Naturally aspirated engines (1960s and 1970s) 

During the 1960s, several minor F1 teams used Alfa Romeo straight-4 engines in cars such as the LDS Mk1 and Mk2 (1962–1963 and 1965), the Cooper T53 (1962), and the De Tomaso F1 (1961). None of these teams scored a single Championships point. 

In 1962, Peter de Klerk created a custom-made, single-seater racing special built for the South African Formula One Championship, powered by an Alfa Romeo Giulietta 1.5-litre straight-4 engine, which was christened as the Alfa Special. The Special participated in two Grands Prixs, retiring at the 1963 South African Grand Prix and finishing 10th at the 1965 South African Grand Prix. It also entered five non-championship Grands Prix, scoring a podium finish at the 1963 Rand Grand Prix.

At the end of the 1960s, Alfa Romeo was developing a new V8 engine for its racing cars, which was briefly tested on the Cooper T86C F1-3-68 by Lucien Bianchi.

Alfa Romeo briefly returned to Formula One for the  and  seasons with a V8 engine based on their sportscar unit used on the Alfa Romeo Tipo 33. In 1970, the unit was mainly entrusted to Andrea de Adamich, a long time Alfa driver, in the McLaren M7D and M14D. The combination often failed to qualify and was uncompetitive when it did run in the races. In 1971, a similar arrangement saw de Adamich run most of the second half of the season in a March 711, with a similar lack of success.

In 1976, Bernie Ecclestone did a deal for the Brabham Formula One team to use Alfa Romeo engines based on their new flat-12 sports car unit designed by Carlo Chiti. The engines were free and produced a claimed  against the  of the ubiquitous Cosworth DFV; however, the 12-cylinder Alfa engine was heavier and used more oil and water than the 8-cylinder DFV, because of more mechanical processes going on in it. Packaging the engines was difficult – they had to be removed to change the spark plugs – and the high fuel consumption engine required no fewer than four separate fuel tanks to contain  of fuel. While the Brabham BT45 (1976 Formula One season) proved quite unsuccessful, the upgraded BT45B represented an proviment. Gordon Murray's increasingly adventurous designs, like the BT46 which won two races in 1978, were partly a response to the challenge of producing a suitably light and aerodynamic chassis around the bulky unit. When aerodynamic ground effect became critical in 1978, it was clear that the low, wide engines would interfere with the large venturi tunnels under the car which were needed to create the ground effect. At Murray's instigation, Alfa produced a narrower V12 design in only three months for the 1979 season, but it continued to be unreliable and fuel-inefficient.

Turbo engines (1980s) 
For the 1987 season, Alfa Romeo made a deal to supply engines to Ligier. A Gianni Tonti designed,  twin turbo 1500 cc straight-4 named the Alfa Romeo 415T was tested in a Ligier JS29 by René Arnoux. When Fiat (the same company that owned F1 giant Ferrari) took control of Alfa Romeo, the deal was cancelled (ostensibly due to negative remarks by Arnoux about the engine, comparing it to used food) and Ligier had to use Megatron (ex BMW) engines for the entire 1987 season.

Alfa also supplied engines to the small and unsuccessful Italian Osella team from 1983 to 1988. Normally aspirated (1983) and turbo (1984–1987) engines were used. In the beginning, Alfa also offered some technical input to the small Turin team; the 1984 Osella (the model FA 1/F) was based on the 1983 works Alfa Romeo 183T, the first chassis was a lightly reworked 183T. All the following Osella models up to the FA1L in 1988 had their origins in the 183T design.

By 1988, the last turbo season, Alfa was fed up with the negative publicity generated by Enzo Osella's cars, so the Milan-based manufacturer prohibited the further use of its name in connection with the engine. The 1988 engines were simply dubbed "Osella V8". At the end of that season, the relationship finished, ending Alfa Romeo's involvement in Formula One.

Naturally aspirated V10 (1985)
In 1985, Alfa Romeo started a V10 Formula One engine project, in anticipation of the upcoming rules forbidding turbo engines. The engine was targeted to be used with Ligier Formula One cars. This was the first modern V10 Formula One engine, followed soon by Honda and Renault engines. The Alfa Romeo V1035 F1 engine was designed by Pino D'Agostino during the 1986 season. In its first stage the 3.5 litre engine produced  and the last version from 1986 could produce  at 13300 rpm. After the co-operation with Ligier was cancelled the engine was available to the 164 Pro Car project.

In 1988, Alfa Romeo (Fiat Group) bought Motor Racing Developments Ltd. (otherwise known as the Brabham F1 team) to build a chassis for a new ProCar series. The car developed was V10 powered Alfa Romeo 164 ProCar (Brabham BT57) and was planned to race in a special racing series (as a support event to Formula One Grands Prix).

Team partnerships

Scuderia Ferrari (2015–2018) 
Alfa Romeo branding appeared on the Scuderia Ferrari Formula One cars from the 2015 until the 2018 season, starting with the Ferrari SF15-T.

Sauber F1 Team (2018) 

On 29 November 2017, it was announced that Alfa Romeo would be the title sponsor of the Sauber Formula One team starting from the 2018 season in a multi-year technical and commercial partnership agreement as Alfa Romeo Sauber F1 Team. On 2 December 2017, a press conference was held at the Alfa Romeo Museum in Arese, Milan, illustrating the terms of the agreement between the FCA Group and the Swiss team followed by a presentation ceremony for the livery and the driver line-up consisting of Charles Leclerc and Marcus Ericsson. 

A January 2018 interview with Frederic Vasseur revealed that Alfa Romeo were intending to take over the Sauber team. On 1 February 2019, it was announced that the team would enter the  season as Alfa Romeo Racing with the ownership and management structure remaining unchanged.
