1950-1951

Automobiles Talbot S.A. was a French automobile manufacturer based in Suresnes, Hauts de Seine, outside Paris. The Suresnes factory had been built by Alexandre Darracq for his pioneering car manufacturing business begun in 1896.  Darracq sold his remaining portion of his business in 1912.

In the 1940's Talbot-Lago produced their T26C that would race in many compititions in the hands of varying drivers. A version of this car also took outright victory at the Le Mans 24 Hour in 1950.

The car would be present on the grid during 1950 and 1951 seasons and took podium finishes in the hands of Louis Rosier.

When the rule change made the big T26C extempt in 1952, Talbot-Lago withdrew from Formula 1.

The T26C made its competition debut at the 1948 Monaco Grand Prix. It retired after 16 laps with engine trouble, but at the Coupe du Salon at Montlhery a 1-2-3 was achieved by Louis Rosier, Pierre Levegh and Yves Giraud-Cabantous.

The first major victory came at the 1949 Belgian Grand Prix with Louis Rosier at the wheel who didn't stop for the entire three and half hours. Superior fuel consumption and reliability helped him against savvy competition like the Alfa Romeo 4CLT with it's two-stage supercharged engine.

1959

Tec-Mec (full name Studio Tecnica Meccanica) was a Formula One constructor from Italy. Founded by former Maserati designer Valerio Colotti in 1958, they participated in a single Grand Prix, scoring no World Championship points.

Tec-Mec used an improved, lightened version of the Maserati 250F, named the F415. The car was upgraded by the 250F's designer, Colotti, and financed by Lloyd Casner of Camoradi International. The team made its single outing in the 1959 United States Grand Prix, but the car, driven by Fritz d'Orey lasted six laps before retiring, having qualified 17th on the grid ahead of only the midget racer of Rodger Ward.

Colotti sold the design studio at the end of the year to found Colotti Trasmissioni, and the company continued to produce cars for the Formula Junior series.

1972-1973

Tecno is an Italian kart and former racing car constructor based in Bologna. It won the European Formula Two Championship in 1970 and became a Formula One constructor, participating in 10 grands prix and scoring one championship point.

Tecno's Formula One car made its first competitive appearance at the 1972 Belgian Grand Prix in the hands of Nanni Galli. The team chose to adopt the colour red for the chassis. The engine, designed by Luciano Pederzani, Renato Armaroli and Giuseppe Bocchi, was a flat-twelve engine very similar to the contemporary Ferrari unit, although apparently considerably less powerful. Galli managed to finish third in the non-valid for the championship 1972 Italian Republic Grand Prix in Vallelunga, but he wouldn't score points for the rest of the season. For the Italian Grand Prix Tecno fielded a second car driven by Derek Bell. Although Galli outqualified Bell, team manager David Yorke elected to retain Bell for the final two races in North America, terminating Galli's involvement with the company.

Because of ongoing problems  the Pederzanis decided to shut down the Formula One program. Rossi took the Martini & Rossi sponsorship to Brabham in 1974, and eventually established the racing brand Martini Racing; Luciano and Gianfranco Pederzani retired from the sport, citing the toxic atmosphere that pervaded the team in 1973 as the main cause of their disillusionment.

1978, 1981–1983

Theodore Racing was a Formula One constructor from Hong Kong founded by real estate magnate and millionaire Teddy Yip. They participated in 51 grands prix, entering a total of 64 cars.

In the present day Theodore Racing is an international motor racing team owned by Teddy Yip Jr.  competing in the Macau Grand Prix.

Theodore began participating in Indy cars in 1977 as a sponsor for the Simpson Sport team. In 1980, Theodore returned with AAR and Mosley. They originally fielded the No. 48 Eagle 80-Cosworth DFX at the Datsun Twin 200 at Ontario Motor Speedway. In 1981, Theodore fielded their own car. They first appeared at the Indianapolis 500 (part of the USAC Gold Crown Series with the No. 33 Red Roof Inns McLaren M24-Cosworth|Cosworth DFX with Vern Schuppan driving. The car qualified in 18th place and finish in third place. At the 1982 Indianapolis 500 (counted toward the 1981–82 USAC Gold Crown Series) Theodore would field, with Bob Fletcher Racing a car for Desire Wilson, the No. 33 Eagle 81-Cosworth DFX. Wilson failed to qualify.

1974

Token Racing was a short-lived Formula One team and constructor from the United Kingdom, participating in four Grands Prix of the 1974 Formula One season.

In late 1973 Rondel Racing, by now a successful Formula Two team founded by Ron Dennis and Neil Trundle, decided to enter F1. Dennis asked Ray Jessop to design the car, while backing was to come from the French oil company Motul, which had sponsored the team for the previous two years. 

The team made its F1 debut in April 1974 at the non-Championship International Trophy race at Silverstone, with Welshman Tom Pryce at the wheel.

After sitting out the next three races, Token reappeared at the British Grand Prix with David Purley in place of Pryce. But after failing to qualify, Purley left and was replaced. The rest of the season was unfortunate for the team and this stage the team had run out of money, and Vlassopulos and Grob closed it down. The RJ02 subsequently passed into the hands of the Safir Engineering company.

1981-1985

Toleman Motorsport was a Formula One constructor based in the UK. It was active between 1981 and 1985 and participated in 70 Grands Prix. The Toleman company was formed in 1926 by Edward Toleman for the purpose of delivering Ford cars from their factory in Old Trafford, Manchester.

Toleman's entry to Formula One was announced in November 1980. Discussions took place with Lancia over the supply of a turbocharged engine, but the team decided to use a turbocharged version of the Hart F2 engine. By that time, Formula One was beginning to be dominated by turbo-powered cars, leaving the naturally aspirated engines lagging behind.

Early in the 1984 season, Ayrton Senna recorded his only failure to qualify for a Formula One Grand Prix. At round four of the championship, the San Marino Grand Prix at Imola, Toleman decided not to run their cars during Friday qualifying after to a dispute with tyre supplier Pirelli. Senna then suffered a fuel pressure problem which left him stranded.

In May 1985, Toleman acquired major sponsorship from the Benetton clothing company, which had previously sponsored Tyrrell and were at the time the major sponsor of the Alfa Romeo team. During the 1985/86 off-season, the knitwear firm purchased the team and it was renamed Benetton Formula prior to the 1986 season. The team, through numerous sales, became the Renault factory team in 2016.

2006-2019

Scuderia Toro Rosso, commonly known as Toro Rosso or by its abbreviation STR, was an Italian Formula One racing team. The Italian name "Toro Rosso" translates to "Red Bull". It was one of two Formula One teams owned by Austrian beverage company Red Bull, the other being Red Bull Racing. Toro Rosso functioned as a junior team to Red Bull Racing, with the aim of developing the skills of promising drivers for the senior team. The team made its racing début in the 2006 season, moving to complete independence from its sister team in 2010. The team changed its name to Scuderia AlphaTauri in 2020.

The team was established after Paul Stoddart sold his remaining interest in the Minardi team at the end of 2005 to Red Bull's owner, Dietrich Mateschitz, and Minardi was renamed Toro Rosso.

From 2007 to 2013, Toro Rosso used Ferrari V8 engines, taking over the contract that their senior team broke from at the end of 2006 to switch engine builders to Renault. For 2014, Toro Rosso switched to Renault engines as well, but in 2016 returned to using Ferrari power. However, they switched back to Renault in 2017 (albeit under 'Toro Rosso' branding), then in 2018 to Honda. The team principal was Franz Tost, formerly of BMW's motor sport division.

2002-2009

Panasonic Toyota Racing was a Formula One team owned by the Japanese automobile manufacturer Toyota Motor Corporation and based in Cologne, Germany. Toyota announced their plans to participate in Formula One in 1999, and after extensive testing with their initial car, dubbed the TF101, the team made their debut in 2002. The new team grew from Toyota's long-standing Toyota Motorsport GmbH organisation, which had previously competed in the World Rally Championship and the 24 Hours of Le Mans. Despite a point in their first-ever race, Toyota never won a Grand Prix, their best finish being 2nd position, which they achieved five times.

Toyota drew criticism for their lack of success, as they never managed to win a Grand Prix with one of the sport's biggest budgets along with being the world's largest car manufacturer. Toyota was a well-funded team, but despite this, strong results had never been consistent.

On 4 November 2009, Toyota announced its immediate withdrawal from Formula One, ending the team's involvement in the sport after eight consecutive seasons.

2004 also saw Toyota being accused of industrial espionage in the case of stolen data files from Ferrari. This following a season where many Formula One fans commented on similarities of the Toyota TF104 to the Ferrari F2003-GA. 

1974

Trojan was an automobile manufacturer and a Formula One constructor, in conjunction with Australian Ron Tauranac, from the United Kingdom.

n 1962, Trojan acquired the Elva sports car business and started to make the Mk IV Elva Courier. This in turn led to the manufacturing of McLaren racing cars until vehicle production finally ceased in the early 1970s. Trojan Limited still exists as an independent company though the factory was sold in the 1970s.

They participated in eight grands prix, entering a total of eight cars. In 1974 David Purley won the Brighton Speed Trials driving a Trojan-Chevrolet T101. While Formula One remained the major series, sports cars were also fashionable on either side of the Atlantic. The McLaren M1 was put into production by Peter Agg's Lambretta Trojan Group in Rye, Sussex. They would make 200 McLarens during ten years. The budget was exhausted by September and the team closed down after the Italian GP.

1970-1998

The Tyrrell Racing Organisation was an auto racing team and Formula One constructor founded by Ken Tyrrell which started racing in 1958 and started building its own cars in 1970. The team experienced its greatest success in the early 1970s, when it won three Drivers' Championships and one Constructors' Championship with Jackie Stewart. The team never reached such heights again, although it continued to win races through the 1970s and into the early 1980s, taking the final win for the Ford Cosworth DFV engine at Detroit in 1983. The team was bought by British American Tobacco in 1997 and completed its final season as Tyrrell in 1998.

With the help of Elf and Ford, Tyrrell then achieved his dream of moving to Formula One in 1968 as team principal for Matra International, a joint-venture established between Tyrrell's own privateer team and the French auto manufacturer Matra. For the 1969 championship, the Matra works team decided not to compete in Formula One. Matra would instead focus its efforts on Ken Tyrrell's 'Matra International' team. In 1977, the Turbo era dawned in Grand Prix racing, which was, by the mid-1980s, to render normally-aspirated-engined cars obsolete. Without the proper funding, Tyrrell was the last to race with the Cosworth DFV when all other teams had switched to turbocharged engines.

1954-1960

Vanwall was a motor racing team and racing car constructor that was active in Formula One during the 1950s. Founded by Tony Vandervell, the Vanwall name was derived by combining the name of the team owner with that of his Thinwall bearings produced at the Vandervell Products factory at Acton, London. Originally entering modified Ferraris in non-championship races, Vanwall constructed their first cars to race in the 1954 Formula One season. The team achieved their first race win in the 1957 British Grand Prix, with Stirling Moss and Tony Brooks sharing a VW 5, earning the team the distinction of constructing the first British-built car to win a World Championship race. Vanwall won the inaugural Constructors' Championship in Formula One in 1958, in the process allowing Moss and Brooks to finish second and third in the Drivers' Championship standings, winning three races each. Vandervell's failing health meant 1958 would be the last full season; the squad ran cars in a handful of races in the following years, but finished racing in 1961.

1992

Venturi is a Monaco-based automotive manufacturer. Founded in 1984 by French engineers Claude Poiraud and Gérard Godfroy as MVS (Manufacture de Voitures de Sport), the company's purpose was to compete in the "Grand Tourisme" market. This was only the most recent post-war attempt at building a sporty luxury car in France, following in the footsteps of Facel Vega, Monica, and Ligier.^[1] As with its predecessors, Venturi was immediately faced with many challenges ranging from an unknown name to its under-capitalized and under-staffed state. Venturi did nonetheless manage to continue in production for nearly sixteen years, declaring bankruptcy in 2000.

The Venturi LC92 (also known as the Venturi Larrousse LC92 or the Larrousse LC92) was a Formula One racing car designed by Robin Herd, Michel Tétu and Tino Belli for the 1992 Formula One season. Built to replace the Lola LC91 used in the previous season, after Larrousse had ended their agreement with Lola, the LC92 used a 3.5-litre Lamborghini 3512 V12 engine. It was the first car that Larrousse had built since Venturi had bought a controlling stake in the team, with Bertrand Gachot and Ukyo Katayama being selected to drive the car. Although the LC92 finished more races than its predecessor, it was no quicker, and Gachot scored the team's only point of the season at the 1992 Monaco Grand Prix. After Venturi sold their stake in Larrousse at the end of the season, the LC92 was replaced by the Larrousse LH93, which was marginally more successful.

1951-1953

Veritas was a West German post World War II sports and race car company, located in the village of Hausen am Andelsbach, near Sigmaringen, Baden-Württemberg. It later moved to Meßkirch and Muggensturm and finally to the Nürburgring.

The company was founded by Ernst Loof, Georg Meier and Lorenz Dietrich who initially re-built and tuned pre-war BMW 328 cars using components supplied by the customer, turning them into BMW-Veritas cars. The first car was used in 1947 Karl Kling to win at Hockenheim and subsequently become the 1947 German 2-litre champion. After only a few cars were made, following an objection from BMW, the cars became simply known as Veritas.

In 1951, a Veritas was converted into a single-seat Formula 1 racer known as the Meteor. Run under the F2 regulations, many cars contested the 1951 and 1952 German Grand Prix with mediocre results. By 1953, the small firm closed and Ernst Loof went back to BMW.

2010-2011

Virgin Racing (subsequently Marussia Virgin Racing) was a Formula One racing team which was under management of Manor Motorsport, Wirth Research and Richard Branson's Virgin Group which competed in Formula One in 2010 and 2011. It scored no points and finished last in the Constructor's Championship for the two years the team competed.

The team was one of the four granted an entry for the 2010 season, and was originally known as Manor Grand Prix, before being renamed Virgin Racing when Virgin brought a shareholding and naming rights at the end of 2009. The team's original car, the Virgin VR-01, was the first in Formula One to be developed using only computational fluid dynamics, and was driven by Timo Glock and Lucas di Grassi. At the end of the season, Marussia Motors bought a stake in the team and became the main sponsor, with the team known as Marussia Virgin Racing and racing under a Russian licence for 2011. The partnership with Wirth ended midway through 2011, and a new technical structure bringing car development in-house was set up for 2012.

Marussia Virgin Racing was renamed to Marussia F1 Team at the end of 2011. The company retained its base in Dinnington, South Yorkshire as well as setting up the technical base in Banbury, Oxfordshire for the construction of the racing cars.

1978-present

Williams Grand Prix Engineering Limited, currently racing in Formula One as Williams Racing, is a British Formula One motor racing team and constructor. It was founded by former team owner Frank Williams and automotive engineer Patrick Head. The team was formed in 1977 after Frank Williams's earlier unsuccessful F1 operation: Frank Williams Racing Cars (which later became Wolf–Williams Racing in 1976). All of Williams F1 chassis are called "FW" then a number, the FW being the initials of team co-founder and original owner, Frank Williams.

The team's first race was the 1977 Spanish Grand Prix, where the new team ran a March chassis for Patrick Nève. Williams started manufacturing its own cars the following year, and Switzerland's Clay Regazzoni won Williams's first race at the 1979 British Grand Prix. At the 1997 British Grand Prix, Canadian Jacques Villeneuve scored the team's 100th race victory, making Williams one of only four teams in Formula One, alongside Ferrari, fellow British team McLaren, and Mercedes to win 100 races. Williams won nine Constructors' Championships between 1980 and 1997. This stood as a record until Ferrari surpassed it in 2000.

In May 2020, Williams announced they were seeking buyers for a portion of the team due to poor financial performance in 2019 and that they had terminated the contract of title sponsor ROKiT. On 21 August 2020, Williams was acquired by Dorilton Capital.

1977-1979

Walter Wolf Racing was a Formula One constructor active from 1977 to 1979, which won the first race the team entered. It was owned and run by Canadian Walter Wolf. The team was based in Reading, UK but raced with the Canadian licence.

In 1975, the Austrian naturalized Canadian businessman Walter Wolf had started to appear at many of the F1 races during the season. A year later, he bought 60% of Frank Williams Racing Cars while agreeing to keep Frank Williams as manager of the team. Simultaneously Wolf bought the assets of Hesketh Racing and bought some equipment from Embassy Hill, both teams having recently withdrawn from F1.  The team, however, was not very competitive and failed to qualify at a number of races during the year. In 1979, Scheckter was signed up by Ferrari and Wolf signed James Hunt to replace him. Postlethwaite designed the WR7 which ran with Olympus sponsorship. The car was not very successful and retired more than 7 times during the first half of the season. The WR8 soon followed. In mid-season Hunt decided to retire and Wolf quickly hired Keke Rosberg to replace him. The appearance of the WR9 did little to change the team's fortunes and at the end of the year Wolf grew tired of his F1 adventure and sold the team to Emerson Fittipaldi, who merged its assets into Fittipaldi Automotive.

1985-1989

Zakspeed  is a motor racing team from Germany, founded in 1968 by Erich Zakowski and after that run by his son Peter Zakowski. It is based in Niederzissen, Rhineland-Palatinate, around 25 kilometres  from the Nürburgring circuit.

In 1982, Zakspeed ran the works Ford C100 Group C effort in conjunction with the factory. The Zakspeed-prepared machine was run by the works Ford Germany team with Klaus Ludwig, Manfred Winkelhock and Marc Surer at the wheel, but the car was a midfielder at best. The engine was the basis for their Formula One entry from 1985 to 1988. In spite of the team's engineering expertise, Zakspeed never managed to create a competitive chassis/engine package. Their first car, the 184, debuted in 1985, one year after the original plan, and was already outdated.

For their final season, in 1989, they had to use Yamaha engines as turbos were banned. The Japanese engine was unreliable and drivers Bernd Schneider (former German Formula 3 champion) and the rookie Aguri Suzuki struggled to pre-qualify the car. Schneider only qualified the car twice and retired both times, while Suzuki never got past pre-qualifying. In the end, Zakspeed were notable for building their own chassis and engine, something only Ferrari did at that time, but with no competitive showings in five years, the team left Formula One and returned to touring cars, where they had once been at the top of the game.
