167-542: BMW decided to return to Formula One in the late 1990s by signing an exclusive contract with the Williams team, which needed a new long-term engine supplier after the withdrawal of Renault in 1997 . The programme resulted in the creation of a new V10 engine which made its race début in the Williams FW22 in 2000 . The following year saw the partnership move from the midfield to challenging for race victories, but

334-490: A Lola F2 chassis powered by an enlarged BMW engine which meant that it conformed with the Formula One regulations, while David Hobbs was entered by Lola in the same combination with the standard smaller BMW engine. For the 1968 race , Hahne returned with the previous year's combination and finished tenth, BMW's best result up to this point in its Formula One history. BMW then entered three of its own 269 F2 chassis for

501-406: A compressor in the turbocharger pressurises the intake air before it enters the inlet manifold . In the case of a turbocharger, the compressor is powered by the kinetic energy of the engine's exhaust gases, which is extracted by the turbocharger's turbine . The main components of the turbocharger are: The turbine section (also called the "hot side" or "exhaust side" of the turbo) is where

668-478: A long safety car period. The media was initially told Kubica had broken his leg, but it later proved that he had escaped with only a sprained ankle and concussion. Vettel took his place in the United States Grand Prix , finishing in eighth place and therefore becoming the youngest driver to score a Formula One World Championship point. Later in the season, Vettel moved teams to take a race seat at

835-460: A lower boost threshold, and greater efficiency at higher engine speeds. The benefit of variable-geometry turbochargers is that the optimum aspect ratio at low engine speeds is very different from that at high engine speeds. An electrically-assisted turbocharger combines a traditional exhaust-powered turbine with an electric motor, in order to reduce turbo lag. This differs from an electric supercharger , which solely uses an electric motor to power

1002-636: A new record for the most wins by a single driver in one year. Despite this, there looked to be significant upheaval at Williams for 1993; what followed led to a domino effect that had not only effects on the World Championship, but also the CART -sanctioned PPG IndyCar Series . Williams was interested in signing Alain Prost to drive one of its two cars for 1993 as he was returning from his year long sabbatical after being sacked by Scuderia Ferrari during

1169-782: A race that season and finished seventh in the Constructors' Championship, scoring 20 points. The highlights of the season for the team were two second-place finishes by Mansell. When Mansell was forced to miss two races due to illness, he was replaced by Martin Brundle for Belgium and Jean-Louis Schlesser for Italy. Schlesser's collision with Ayrton Senna in that race would deny McLaren a clean sweep of race wins that season. The team secured Renault as their engine supplier in 1989. Renault engines subsequently powered Williams's drivers to another four Drivers' and five Constructors' Championships up until Renault's departure from Formula One at

1336-480: A realistic chance of taking at least one title. The lack of development was reflected with a drop of form throughout the second half of the season, causing BMW to be outpaced by Renault, Toyota and even Toro Rosso (who started the season as one of the slowest teams) by the end of the season. Despite this, Kubica remained with an outside chance of taking the drivers championship until the Chinese Grand Prix,

1503-512: A ring of holes or circular grooves allows air to bleed around the compressor blades. Ported shroud designs can have greater resistance to compressor surge and can improve the efficiency of the compressor wheel. The center hub rotating assembly (CHRA) houses the shaft that connects the turbine to the compressor. A lighter shaft can help reduce turbo lag. The CHRA also contains a bearing to allow this shaft to rotate at high speeds with minimal friction. Some CHRAs are water-cooled and have pipes for

1670-645: A second 1–2 after Hill won the French Grand Prix . Villeneuve won his second race in F1 at Silverstone after Hill retired with a wheel bearing failure on lap 26. Hill was victorious in the next Grand Prix in Germany while Villeneuve won the race after that in Hungary . Schumacher's Ferrari would then take the next two Grands Prix at Spa-Francorchamps and Monza . Villeneuve mounted a title challenge going into

1837-613: A single point the previous year. He won the Drivers' title that year despite winning only one race, the Swiss Grand Prix . Rosberg's teammate, Reutemann , finished in 15th place having quit Formula One after just two races of the new season. His seat was filled by Mario Andretti for the United States Grand Prix West ; before Derek Daly took over for the rest of the year. Williams finished fourth in

2004-620: A step up for the 1992 season, keeping their 1991 driver line-up of Patrese and Mansell . Mansell dominated the first round in South Africa , qualifying in pole position and winning the race by 24 seconds from his teammate, Patrese. Nigel Mansell won the next four rounds for Williams, at Mexico City , Interlagos , Catalunya and Imola , Patrese coming second in all but one (the Spanish Grand Prix at Catalunya, where he retired after spinning off). Mansell's five victories in

2171-418: A technical director (rather than just chief designer), but this was not possible at Williams, as Patrick Head was a founder and shareholder of the team. McLaren lured Newey away, though he was forced to take garden leave for the majority of 1997. Turbocharger In an internal combustion engine , a turbocharger (also known as a turbo or a turbosupercharger ) is a forced induction device that

2338-484: A technical partnership with technology company Intel . The team's new livery, which was maintained throughout its tenure in Formula One, consisted of the traditional BMW blue and white with a hint of red. Villeneuve scored the team's first points with a seventh-place finish at the Malaysian Grand Prix , after Heidfeld retired from fifth with an engine failure late in the race. Over the first two thirds of

2505-474: A ten-year absence from Formula One , BMW began evaluating a return to the sport in the late 1990s. In 1998 , the marque signed a contract to supply the Williams team with engines. Williams had won the 1992 , 1993 , 1996 and 1997 Drivers' Championships, and the Constructors' Championships in all of these years as well as 1994 , in a successful partnership with Renault , but the French company withdrew from

2672-637: A turbocharger was in June 1924 when the first heavy duty turbocharger, model VT402, was delivered from the Baden works of Brown, Boveri & Cie , under the supervision of Alfred Büchi, to SLM, Swiss Locomotive and Machine Works in Winterthur. This was followed very closely in 1925, when Alfred Büchi successfully installed turbochargers on ten-cylinder diesel engines, increasing the power output from 1,300 to 1,860 kilowatts (1,750 to 2,500 hp). This engine

2839-582: A type of fuel for which samples had not been provided to the FIA . Thus, Gerhard Berger and Ferrari were declared winners. Schumacher and Coulthard had their positions reinstated after appeal, though Benetton and Williams were not awarded their Constructors' points. Hill won the next two races in Argentina and San Marino and would later win races at The Hungaroring and in Adelaide . Hill won two laps ahead of

3006-474: Is increasing. The companies which manufacture the most turbochargers in Europe and the U.S. are Garrett Motion (formerly Honeywell), BorgWarner and Mitsubishi Turbocharger . Turbocharger failures and resultant high exhaust temperatures are among the causes of car fires. Failure of the seals will cause oil to leak into the cylinders causing blue-gray smoke. In diesel engines, this can cause an overspeed,

3173-407: Is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement . The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until

3340-453: Is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the turbo's aspect ratio can be maintained at its optimum. Because of this, variable-geometry turbochargers often have reduced lag,

3507-441: Is unable to produce significant boost. At low rpm, the exhaust gas flow rate is unable to spin the turbine sufficiently. The boost threshold causes delays in the power delivery at low rpm (since the unboosted engine must accelerate the vehicle to increase the rpm above the boost threshold), while turbo lag causes delay in the power delivery at higher rpm. Some engines use multiple turbochargers, usually to reduce turbo lag, increase

3674-417: The 1969 race , for the trio of Hahne, Gerhard Mitter and Dieter Quester , but Mitter was fatally injured in a practice accident and the remainder of the team withdrew from the race. Following the commencement in 1977 of Renault's Formula One project with a turbocharged engine and increasing success thereafter, BMW decided to develop its own turbo engine for the sport, a programme which it announced to

3841-528: The 1981 British Grand Prix , where Piquet set a qualifying time 0.7 seconds slower than his effort in the Cosworth DFV -powered BT49. The BT50 handled poorly but recorded 192 miles per hour (309 km/h) through the speed trap, some 15 miles per hour (24 km/h) faster than the BT49. Meanwhile, Brabham won the Drivers' Championship with Piquet, who drove the BT49 throughout the season. Brabham began

4008-643: The 1982 season with two BMW-powered BT50 chassis at the South African Grand Prix , where Piquet and Patrese qualified second and fourth respectively, but retired early in the race. Team principal Bernie Ecclestone was under pressure from the team's title sponsor, Parmalat , to defend Piquet's championship, and opted to race with the Cosworth-powered BT49 chassis at the Brazilian Grand Prix , which Piquet won but

4175-726: The 1991 season. Replacing him was a returning Nigel Mansell , who had spent the previous two seasons driving for Ferrari . Williams also recruited future 1996 world champion, Damon Hill , as their reserve driver. Williams failed to finish the first Grand Prix of the season, the US Grand Prix , with both drivers retiring due to gearbox problems. Patrese got back on track for the team in the next Grand Prix at Interlagos , coming second behind McLaren's Ayrton Senna . The 1991 San Marino Grand Prix saw both cars retiring yet again: with Mansell crashing and Patrese suffering from an electrical failure. The Monaco Grand Prix saw Mansell finish in

4342-776: The 1996 championship. None of Williams's Drivers' Champions went on to win another championship after their success with Williams. Williams have worked with many engine manufacturers, most successfully with Renault , winning five of their nine Constructors' titles with the company. Along with Ferrari , McLaren , Benetton and Renault , Williams is one of a group of five teams that won every Constructors' Championship between 1979 and 2008 and every Drivers' Championship from 1984 to 2008. Williams also has business interests beyond Formula One. They have established Williams Advanced Engineering and Williams Hybrid Power, who take technology originally developed for Formula One and adapt it for commercial applications. In April 2014, Williams Hybrid Power

4509-759: The 2008 season. Their 2008 car, the F1.08 was officially launched in Munich at BMW Welt on January 14, 2008. It made its track debut at Valencia the next day, with Robert Kubica driving. Team principal Mario Theissen set the target of the team's first win. BMW Sauber started the season well with Kubica narrowly missing out on pole after a mistake in his main qualifying lap in Melbourne . He later retired after being hit by Kazuki Nakajima but Heidfeld finished second. Kubica took second in Malaysia , with Heidfeld in 6th setting

4676-591: The Austrian Grand Prix the previous season for a devastated Shadow team following the death of their lead driver, Tom Pryce . Jones's first race for the team was the Argentine Grand Prix where he qualified in 14th position but retired after 36 laps due to a fuel system failure. The team scored its first championship points two races later at the South African Grand Prix when Jones finished in fourth. Williams earnt their first podium at

4843-566: The Austrian Grand Prix , finishing half a minute ahead of Gilles Villeneuve's Ferrari. Three wins in a row became four two weeks later at the Dutch Grand Prix , with Alan Jones winning yet again by a comfortable margin over Jody Scheckter 's Ferrari. Scheckter ended Williams's winning streak when he won the Italian Grand Prix ; with Regazzoni finishing third behind Scheckter and Villeneuve. Alan Jones managed another win at

5010-557: The BMW M1 Procar Championship , the rounds of which were held during Grand Prix race weekends, thus strengthening the marque's ties with the sport. At the same time, Jochen Neerpasch oversaw the development by Paul Rosche of a prototype 1.4-litre turbo engine, which soon developed 600 bhp at a pressure of 2.8 bar. It was equipped with a single Kühnle, Kopp & Kausch (KKK) turbocharger and Bosch electronics, including fuel injection. This engine formed

5177-717: The BMW Sauber F1 Team (initially BMW planned to utilize BMW F1 Team naming). The takeover came after BMW's relationship with Williams had deteriorated in the previous months, the partnership ending at the end of the 2005 season. The team, operated under a German racing licence , was based at Sauber's headquarters in Hinwil , Switzerland and BMW's headquarters in Munich , Germany. BMW retained Sauber naming for 2006 to 2009 seasons due to historical reasons despite BMW ownership. The team scored two podium finishes and came fifth in 2006 , its first season in Formula One.

5344-578: The Brabham team. Testing of the M12/13 got underway in late 1980 with a Brabham BT49 chassis converted to accept the engine. The team's designer, Gordon Murray , designed a new car, the BT50 for the engine, but it was not completed until well into the 1981 season. The BT50 featured a longer wheelbase and a larger fuel cell than the BT49 to accommodate the requirements of the more powerful turbo engine, and

5511-561: The Brazilian Grand Prix and the Belgian Grand Prix . Williams won the Constructors' title for the second year in a row, scoring 95 points, 34 points more than second-placed Brabham. This season, Alan Jones retired from Formula One (though he would come back a year later for a single race with the Arrows team). The Australian was replaced by Keke Rosberg , the father of 2016 World Champion Nico Rosberg . Rosberg had not scored

5678-510: The British Grand Prix . (In the final round, in Adelaide , the two Williams cars again retired, Mansell after Senna violently crashed into the back of him, and Patrese with electrical problems.) Williams won the Constructors' Championship with 164 points, 65 points more than second-place McLaren. Mansell became World Champion, scoring 108 points, with Patrese finishing second with 56 points. Placing first in nine races, Mansell had set

5845-594: The British Grand Prix . Hill closed the points gap with Schumacher, who was disqualified from first at Spa after the Stewards found floorboard irregularities on his Benetton. He was banned for the next two races, and Hill capitalised on this with wins in Italy and a Williams 1–2 in Portugal . With three races left, 1992 champion Nigel Mansell returned from CART (where the season had concluded) to replace Coulthard for

6012-542: The Canadian and Detroit Grands Prix. The second Brabham was filled in most races by Teo Fabi , who attempted to compete in a full season of IndyCars , but committed to F1 full-time part-way through the year. Due to his American commitments he missed three races, in which he was substituted by his brother, Corrado . Winkelhock also raced for the team in the final race of the season after the Fabis' father died shortly before

The first practical application for trucks was realized by Swiss truck manufacturing company Saurer in the 1930s. BXD and BZD engines were manufactured with optional turbocharging from 1931 onwards. The Swiss industry played a pioneering role with turbocharging engines as witnessed by Sulzer, Saurer and Brown, Boveri & Cie . Automobile manufacturers began research into turbocharged engines during

6346-473: The Drivers' title with the team. Of those who have won the championship with Williams, only Jones, Rosberg and Villeneuve defended their title while still with the team; as Piquet moved to Lotus after winning the 1987 championship; Mansell left F1 to compete in the CART series after winning the 1992 championship, Prost retired after winning the 1993 championship, and Hill moved to Arrows after winning

6513-598: The FW07 chassis and gearbox for the 1979 season with Frank Dernie picking up the suspension, aerodynamic development and skirt design. This was the team's first ground effect car, a technology that was first introduced by Colin Chapman and Team Lotus . Williams also obtained membership of the Formula One Constructors' Association (FOCA) which expressed a preference for teams to run two cars, so Jones

6680-538: The French Grand Prix , five seconds ahead of Alain Prost 's Ferrari . Mansell then won again at the British Grand Prix ; it had been four years since a Briton had won the Grand Prix, Mansell having won it in 1987 . Three consecutive victories became four when Mansell won again in Germany , with Patrese about 10 seconds behind him in second place. Senna ended Williams's run of victories by winning in Hungary , finishing five seconds ahead of Mansell. Mansell later won

6847-561: The Italian Grand Prix and the Spanish Grand Prix , while Patrese won the Portuguese Grand Prix after Mansell's race was ruined by a botched pitstop in which only three wheel nuts were fitted. Williams finished second in the Constructors' Championship, scoring 125 points in total, 14 points behind McLaren. Mansell finished second in the Drivers' Championship with 72 points, 24 points behind Senna. Williams took

7014-541: The Ligier team. Neerpasch had arranged the sale of Rosche's M12/13 engine to Talbot, but Rosche and Neerpasch's successor, Dieter Stappert , successfully protested to their board that such an undertaking deserved full works commitment, particularly as the fact that M12/13 was derived from a production road car engine meant that potential success could be extremely valuable to BMW from a marketing and sales point of view. BMW thus negotiated an exclusive supply of M12/13 engines to

7181-658: The Mexican Grand Prix , the team managed to achieve their first podium with the Renault engine, as Patrese finished second, 15 seconds behind Ayrton Senna in first. The next race saw Patrese finish second again, having started from 14th on the grid, with Boutsen finishing in 6th. At the sixth round in Canada , Williams not only scored their first win with the Renault engine but also their first one-two: with Boutsen finishing in first followed by Patrese in second. This won

7348-626: The National Advisory Committee for Aeronautics (NACA) and Sanford Alexander Moss showed that a turbocharger could enable an engine to avoid any power loss (compared with the power produced at sea level) at an altitude of up to 4,250 m (13,944 ft) above sea level. The testing was conducted at Pikes Peak in the United States using the Liberty L-12 aircraft engine. The first commercial application of

7515-479: The South African Grand Prix . Williams finished in third in the Constructors' Championship, scoring 71 points. During qualifying for the British Grand Prix , Rosberg completed a lap of the circuit in 1:05.591. The lap's average speed was 160.938 mph (259.005 km/h). This was the fastest recorded lap in Formula One history to that point. From 1985 until 1993, Williams ran their famous yellow, blue and white Canon livery. In March 1986, Frank Williams faced

7682-723: The Toro Rosso team. Kubica returned to racing action at the French Grand Prix and proved his recovery by finishing in fourth position. Over the remainder of the season, he and Heidfeld continued their form to score a total of 101 points, which secured the team second in the Constructors' Championship after McLaren's disqualification. Heidfeld scored another podium finish at the Hungarian Grand Prix and scored 61 points to Kubica's 39, while Vettel's sole appearance produced an additional point. On August 21, 2007, BMW confirmed its driver line-up of Heidfeld and Kubica for

7849-521: The United States Grand Prix , where Jones came second, 20 seconds behind the Ferrari of Carlos Reutemann . Williams finished the season in ninth place in the Constructors' Championship, with a respectable 11 points, while Alan Jones finished 11th in the Drivers' Championship. Towards the end of 1978, Frank Williams recruited Frank Dernie to join Patrick Head in the design office. Head designed

A turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, increasing pumping losses. Supercharged engines are common in applications where throttle response is a key concern, and supercharged engines are less likely to heat soak

8183-422: The 17th round out of 18. In October the team confirmed that they would stick with Robert Kubica and Nick Heidfeld as their drivers for the 2009 Season. Although BMW Sauber targeted the 2009 season as the year they would challenge for the title, their start to the season was a disappointment. Kubica was running in 3rd place in the opening round when he collided with Vettel while battling for 2nd place and

8350-511: The 1950s, however the problems of "turbo lag" and the bulky size of the turbocharger were not able to be solved at the time. The first turbocharged cars were the short-lived Chevrolet Corvair Monza and the Oldsmobile Jetfire , both introduced in 1962. Greater adoption of turbocharging in passenger cars began in the 1980s, as a way to increase the performance of smaller displacement engines. Like other forced induction devices,

8517-405: The 1980s. In the 1990 season, Williams kept Patrese and Boutsen as the team's drivers. The team scored 20 fewer points than the previous year and finished fourth in the Constructors' Championship two positions lower than in 1989. In the Drivers' Championship, Boutsen finished sixth with 34 points and Patrese in seventh with 23 points. Boutsen left Williams and joined Ligier at the start of

8684-402: The 1991 World Championship. Patrese, perhaps figuring that he would be the driver being sacked in order for Prost to take one of the two available rides, decided to leave after driving for Williams since 1987. He would join up with Benetton, where he would replace Martin Brundle alongside Michael Schumacher in the team's Camel -backed Fords. Mansell, meanwhile, was not pleased that Williams

8851-520: The 1992 season, to join Prost in the other Renault. The Williams FW15C was an extremely dominant car, with active suspension and traction control systems beyond anything available to the other teams. Prost won on his debut for the team in South Africa and, like Mansell, dominated the weekend, taking pole position and finishing a minute ahead of Senna , who was second. The next Grand Prix in Brazil saw Prost collide with Christian Fittipaldi's Minardi in

9018-470: The 1993 championship and subsequent retirement. Hill retained the number 0, while Senna's car was issued number 2. Pre-season testing showed the FW16 had speed but was difficult to drive. The Fédération Internationale de l'Automobile (FIA) had banned electronic driver's aids, such as active suspension , traction control and ABS , to make the sport more "human". It was these technological advancements that

9185-496: The 2010 Championship. On November 22, Swiss newspaper SonntagsZeitung revealed that Qadbak's attempt to purchase the team had failed as it did not have the necessary funds. Qadbak turned out to be a shell company with no assets and no investors behind it. On November 27, 2009, it was announced that Peter Sauber would repurchase the team conditional upon the team receiving a FIA entry for the 2010 season. The FIA subsequently granted Sauber an entry on December 3, after Toyota had left

9352-551: The Arrows cars in 1987 and 1988 , and the Ligier team in 1987 only. Arrows finished fifth in the Constructors' Championship in the latter of these two seasons, a result which stands as the best in the team's 25-year history. For 1989 , the technical regulations were changed to ban turbocharged engines, outlawing the M12/13 engine. During its time in F1, the engine had won the 1983 Drivers' Championship and nine Grands Prix. It also took 14 pole positions and set 13 fastest laps. After

This left Alain Prost to defend his title successfully, despite being in a slower car. The 1987 season brought the Williams-Honda partnership its first and only Drivers' Championship title in

9686-560: The Constructors' Championship that year, 16 points behind first-place Ferrari . Frank Williams looked towards Honda, who was developing a turbocharged V6 engine with Spirit . A deal between Honda and Williams was settled early in 1983 and the team used the engines for the 1984 season. For the 1983 season however, Williams continued to use the Ford engine except for the last race of the year in South Africa ; where Keke Rosberg finished in an impressive fifth place. The team finished fourth in

With their removal in 1994, Williams had not been a good-handling car, as observed by other F1 drivers, having been seen to be very loose at the rear. Senna himself had made numerous comments that the Williams FW16 had quirks that needed to be ironed out. It was obvious that the FW16, after the regulation changes banning active suspension and traction control, exhibited none of

11690-537: The basis of the M12/13 design, the race unit that BMW ultimately supplied to five teams from 1982 to 1988. Initial discussions were held with double World Champion Niki Lauda and McLaren on the subject of a 1980 campaign, but the BMW board denied Neerpasch's request for the programme. Neerpasch then left his position to join the French Talbot marque, which was also planning to enter Formula One, in this case with

11857-406: The benefits of both small turbines and large turbines. Large diesel engines often use a single-stage axial inflow turbine instead of a radial turbine. A twin-scroll turbocharger uses two separate exhaust gas inlets, to make use of the pulses in the flow of the exhaust gasses from each cylinder. In a standard (single-scroll) turbocharger, the exhaust gas from all cylinders is combined and enters

12024-421: The compressor wheel. Large turbines typically require higher exhaust gas flow rates, therefore increasing turbo lag and increasing the boost threshold. Small turbines can produce boost quickly and at lower flow rates, since it has lower rotational inertia, but can be a limiting factor in the peak power produced by the engine. Various technologies, as described in the following sections, are often aimed at combining

12191-419: The compressor. The compressor draws in outside air through the engine's intake system, pressurises it, then feeds it into the combustion chambers (via the inlet manifold ). The compressor section of the turbocharger consists of an impeller, a diffuser, and a volute housing. The operating characteristics of a compressor are described by the compressor map . Some turbochargers use a "ported shroud", whereby

12358-479: The death of Elio de Angelis in a testing accident after four races; his replacement Derek Warwick and team returnee Patrese scored two points between them all season. The Arrows team also slipped backwards, scoring just one point with Boutsen, Surer and Christian Danner , and also lost Surer's services mid-season when the Swiss driver was seriously injured in a rallying accident. BMW's most successful 1986 partnership

12525-453: The desired championship remained elusive due to the dominance of Michael Schumacher and Ferrari in the first half of the 2000s. By 2005 , the relationship between BMW and Williams had deteriorated, and BMW chose to part company and buy the rival Sauber team outright. The BMW Sauber project lasted from 2006 until 2009 , and resulted in a substantial increase in competitiveness for the Swiss former privateer team. Two podium finishes in

12692-446: The drivers' vision and thus compromise safety. Heidfeld scored the team's first podium finish at the Hungarian Grand Prix from tenth on the grid. This race also saw the début of Robert Kubica , who replaced Villeneuve after the latter had crashed heavily at the preceding German Grand Prix . Kubica finished seventh, although he was later disqualified after his car was found to be underweight. The official reason for Villeneuve's absence

12859-413: The effective aspect ratio of the turbocharger as operating conditions change. This is done with the use of adjustable vanes located inside the turbine housing between the inlet and turbine, which affect flow of gases towards the turbine. Some variable-geometry turbochargers use a rotary electric actuator to open and close the vanes, while others use a pneumatic actuator . If the turbine's aspect ratio

13026-508: The end of 1997. The team brought in Adrian Newey to replace Frank Dernie . The combination of Renault's powerful engine and Adrian Newey 's designing expertise led to the team dominating the sport in the mid-1990s alongside McLaren. Mansell had a record-breaking 1992 season, winning the title in record time and leading numerous races from pole to finish. The Renault era started in 1989 , with Riccardo Patrese and Thierry Boutsen at

13193-458: The end of the year, team owner Bernie Ecclestone , who was increasingly involved in running the commercial side of the sport, decided not to compete the following year, ending BMW's tenure as a supplier of works turbo engines. The Arrows team, however, was still keen to use the upright version of the M12/13, and arranged for its title sponsor, USF&G , to purchase the remaining stock. The engines were rebadged as "Megatrons", and were used to power

13360-403: The engine rpm is within the turbocharger's operating range – that occurs between pressing the throttle and the turbocharger spooling up to provide boost pressure. This delay is due to the increasing exhaust gas flow (after the throttle is suddenly opened) taking time to spin up the turbine to speeds where boost is produced. The effect of turbo lag is reduced throttle response , in

13527-559: The engine's coolant to flow through. One reason for water cooling is to protect the turbocharger's lubricating oil from overheating. The simplest type of turbocharger is the free floating turbocharger. This system would be able to achieve maximum boost at maximum engine revs and full throttle, however additional components are needed to produce an engine that is driveable in a range of load and rpm conditions. Additional components that are commonly used in conjunction with turbochargers are: Turbo lag refers to delay – when

13694-470: The event. In 1985 , Brabham switched to Pirelli tyres, which had previously not been very competitive against the established Goodyear and Michelin suppliers, in the hope that the Italian company could provide bespoke tyres that would especially suit the new BT54 chassis. This proved to be a misjudgement, as Piquet only won one race—the French Grand Prix —and the team dropped from fourth to fifth in

13861-482: The exhaust gases, minimizes parasitic back losses and improves responsiveness at low engine speeds. Another common feature of twin-scroll turbochargers is that the two nozzles are different sizes: the smaller nozzle is installed at a steeper angle and is used for low-rpm response, while the larger nozzle is less angled and optimised for times when high outputs are required. Variable-geometry turbochargers (also known as variable-nozzle turbochargers ) are used to alter

14028-406: The fastest lap of the race. The team's points total of 11 was their largest score up to that time. In Bahrain , Kubica scored his and the team's first ever pole position, beating Felipe Massa by just under three hundredths of a second. The team went on to finish 3rd and 4th in the race, equalling their highest round points total and promoting them to first place in the constructors' championship for

14195-412: The field at Adelaide in one of F1's most dominating victories. Coulthard recorded his only 1995 win for the Williams team at Estoril , before moving to McLaren. Williams's champion streak was ended by Benetton , who elected to switch engine suppliers from Ford to Renault, the same as Williams. As such, Benetton outscored Williams by 29 points in the Constructors' Championship. Damon Hill placed second in

14362-584: The final race of the season at Japan , but Hill reasserted his dominance to take the race and the 1996 title, while Villeneuve lost a wheel and retired. Williams's dominance was such that they had clinched the Constructors' Championship and only their drivers had a mathematical chance of taking the title, several races before the season concluded. Around that time, Frank Williams announced that Hill would not be re-signed after his contract expired, despite Hill's successes and eventual Drivers' Championship, so he joined Arrows for 1997. Adrian Newey had ambitions as

14529-514: The first five Grands Prix, Hill winning all but one of them. Olivier Panis would take victory at the sixth round in Monaco after both Williams cars retired. Hill would retire for the second time in a row after he spun-off in Spain , while his teammate, Villeneuve, took third place. Hill and Villeneuve dominated the next Grand Prix in Canada , with a 1–2 in qualifying and a 1–2 finish. Williams made it

14696-533: The first lap. Since Senna's death, every Williams F1 car has carried a Senna 's' on its livery in his honour and to symbolise the team's ongoing support of the Instituto Ayrton Senna , but cars from 2022 onwards will not have the Senna S, with CEO Capito stating it was time to "move on". At the next race in Spain , Williams brought in test driver David Coulthard as Hill's new teammate. Hill took

14863-579: The first time. The team also attained a second-place finish in the Monaco Grand Prix with Robert Kubica , beating both Ferraris and only trailing the McLaren of Lewis Hamilton by three seconds. BMW Sauber's first race victory came in the 2008 Canadian Grand Prix , the team achieving a one-two finish with Robert Kubica's first race win and Nick Heidfeld taking second place. The victory came after Lewis Hamilton collided with Kimi Räikkönen in

15030-412: The first year were followed by a solid third in the Constructors' Championship in 2007 (which became second when McLaren was disqualified). In 2008 , Robert Kubica won the team's only race, the 2008 Canadian Grand Prix , and led the Drivers' Championship at one point, but the team chose to focus on development of its 2009 car and slipped back in the standings by the end of the season. The 2009 season

15197-412: The following year, and Clay Regazzoni won Williams's first race at the 1979 British Grand Prix . At the 1997 British Grand Prix , Jacques Villeneuve scored the team's 100th race victory, making Williams one of only five teams in Formula One, alongside Ferrari , McLaren , Mercedes , and Red Bull Racing to win 100 races. Williams won nine Constructors' Championships between 1980 and 1997 . This

15364-404: The form of a delay in the power delivery. Superchargers do not suffer from turbo lag because the compressor mechanism is driven directly by the engine. Methods to reduce turbo lag include: A similar phenomenon that is often mistaken for turbo lag is the boost threshold . This is where the engine speed (rpm) is currently below the operating range of the turbocharger system, therefore the engine

15531-405: The gas flow through the turbine section, and the turbine itself can spin at speeds of up to 250,000 rpm. Some turbocharger designs are available with multiple turbine housing options, allowing a housing to be selected to best suit the engine's characteristics and the performance requirements. A turbocharger's performance is closely tied to its size, and the relative sizes of the turbine wheel and

15698-405: The hands of Nelson Piquet . Piquet won three races and scored 73 points in the Drivers' Championship. His teammate Mansell came in second place with six victories and 61 points. Williams won the Constructors' Championship for the second year in a row, scoring 137 points, 61 points ahead of their nearest rivals, McLaren. Despite this success, Honda ended their partnership with Williams at the end of

15865-417: The helm of the two Williams cars. Boutsen replaced Mansell, who had signed a contract with Ferrari. The engine's first Grand Prix in Brazil was one that the team would prefer to forget: Boutsen retired with an engine failure and Patrese with an alternator failure. Williams managed to get back on track with Boutsen finishing in fourth at the next race in Italy ; winning the team three points. Two races later at

16032-502: The intake air. A combination of an exhaust-driven turbocharger and an engine-driven supercharger can mitigate the weaknesses of both. This technique is called twincharging . Turbochargers have been used in the following applications: In 2017, 27% of vehicles sold in the US were turbocharged. In Europe 67% of all vehicles were turbocharged in 2014. Historically, more than 90% of turbochargers were diesel, however, adoption in petrol engines

16199-509: The marque's maiden pole position at the Austrian race. In 1983 , the improved reliability of the BMW engine in the new BT52 allowed Piquet to win the Drivers' Championship, after overhauling Alain Prost (Renault) in the points standings. Brabham also finished third in the Constructors' Championship, although Patrese's lack of consistency in the second car prevented the team challenging for this title. Piquet won three races and Patrese won

16366-654: The media in April 1980. The engine was based on the M10 unit, a four-cylinder, 1.5-litre, normally aspirated engine that had originally been designed in the late 1950s. Its racing derivative, the M12 had also been used in racing throughout the intervening period, winning races in Formula Two and other categories. In 1979 and 1980 , BMW provided a fleet of identical M1 cars for Formula One and other professional drivers to race in

16533-431: The mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. Prior to the invention of the turbocharger, forced induction was only possible using mechanically-powered superchargers . Use of superchargers began in 1878, when several supercharged two-stroke gas engines were built using a design by Scottish engineer Dugald Clerk . Then in 1885, Gottlieb Daimler patented

16700-423: The most serious challenge of his life. While returning to the airport at Nice , France, after pre-season testing, he was involved in a road accident that left him paralysed. He did not return to the pit lane for almost a year. Despite the lack of his trackside presence, the Williams team won nine Grands Prix and the Constructors' Championship and came close to winning the Drivers' Championship with Nigel Mansell, but

16867-588: The new car and both drivers raced without the device. After the qualifying session for the British Grand Prix Mario Theissen announced that the team had decided to halt further development KERS; of which BMW had been one of the strongest proponents, and focus instead on improving the car's aerodynamics. This left Ferrari and McLaren as the only remaining users of the KERS system. In the European Grand Prix at Valencia Robert Kubica scored

17034-403: The new engine supplier, Senna approached Williams and offered to take over the second car. His interest was such that he was willing to drive for Williams while collecting no salary. However, like with Mansell, Prost had a rather testy relationship with Senna from when the two were teammates and rivals at McLaren in the 1980s. As such, he negotiated a two-year contract with Williams that gave him

17201-517: The next race in Canada , where the cool conditions suited the turbocharged engines and allowed Piquet to lead home Patrese (still in the BT49), to record BMW's first Formula One victory. For the remainder of the season, both drivers raced with the BT50, and used Murray's radical strategy of a planned pit stop for refuelling midway through the race to run at the front of the field on numerous occasions. The car

17368-399: The opening five races was a new record in Formula One. Senna won the next race in Monaco , ahead of both Williams cars, which finished second and third. In the next race, in Canada , both Williams cars retired: Mansell spun off on entering the final corner (he claimed that Senna pushed him off) and Patrese had a gearbox failure. Mansell went on to record four more Grand Prix wins, including at

17535-411: The outside wall at the 5th corner (out of sight of Hill). As Schumacher recovered, Hill came around the corner and attempted to overtake into the next corner. Schumacher turned in and the resulting contact (Schumacher in the wall and Hill retiring with bent suspension), meant Schumacher was the champion. This collision has been controversial. Some, such as Williams's Patrick Head , have suggested that this

17702-490: The penultimate race in Canada to cap off a great season. Williams had greatly improved their Constructors' Championship position, finishing eight places higher than the previous year and scoring 59 more points. Alan Jones was the closest driver to the Ferrari duo of Villeneuve and 1979 champion Jody Scheckter. Jones scored 43 points, 17 points behind Scheckter, while Regazzoni was two places behind him with 32 points. Before

17869-579: The penultimate race of the season. However, he ultimately fell short, as did the team in the Constructors' Championship, as although the FW25 was often the car to beat in the second half of the season, it took too much time to reach this point. For 2004 , the team produced the FW26 chassis, which featured a radical nose section designed by Antonia Terzi . This design proved ineffective, however, in another year of Ferrari dominance, and Williams slipped to fourth in

18036-526: The pitlane, ending the race for both drivers. Kubica was on a different refueling strategy from Heidfeld, who also briefly led the race before securing the one-two finish for BMW Sauber in comfortable fashion. After the team's breakthrough win, development was switched to the 2009 season where new regulations come into play. This greatly annoyed Kubica, (who was leading the championship after the Canadian Grand Prix), as he felt they could have had

18203-404: The points for the first time; as Jones was fourth with Regazzoni in sixth. The team's first win came at the British Grand Prix (their home Grand Prix) when Regazzoni finished 25 seconds ahead of second place. Greater success followed when Williams got a 1-2 finish at the next round in Germany , Jones in first with Regazzoni two seconds behind in second. Jones then made it three wins in a row at

18370-487: The points, coming in second. At the next race, the Canadian Grand Prix , Williams locked out the front row only for Patrese to drop back with gearbox problems and Mansell to retire from the lead on the final lap due to an electrical fault. At the following race in Mexico , Williams achieved a 1–2 finish, with Patrese finishing in first and Mansell finishing in second. Williams then ran a streak of victories, with Mansell winning

18537-546: The points. Williams retained their Constructors' title, 84 points ahead of second-placed McLaren. Prost clinched the Drivers' Championship in Portugal and finished the season 26 points ahead of second-placed Senna. Based on his victory in the 1992 World Championship, Mansell would have been issued car number 1 for the 1993 season, and his teammate issued number 2. However, Mansell's move to the IndyCar series meant that number 1

18704-533: The power to approve or disapprove any driver Williams would seek to have him team with for 1993. Once the contract was signed, Prost used that power to freeze Senna out of driving for Williams; he would return to McLaren for one more season with the team running Ford engines. Needing a replacement, Williams decided not to pursue any of the available drivers such as Berger and Brundle. Instead, they chose to promote former Brabham driver Damon Hill , who had been their test driver since Brabham collapsed and folded during

18871-462: The pre-war BMW 328 chassis, entered in the 1952 and 1953 German Grands Prix . BMW-derived cars were also entered by the Alex von Falkenhausen Motorenbau (AFM) and Veritas companies in occasional races from 1951 to 1953 . The entries occurred during this period because the championship was effectively run to Formula Two regulations, allowing the BMW cars to take part. Amongst the modified 328s

19038-417: The previous two World Championships with vastly superior cars, Senna was a natural and presumptive pre-season title favourite, with second-year driver Damon Hill intended to play the supporting role. Between them, Prost, Senna, and Hill had won every race in 1993 but one, which was taken by Benetton's Michael Schumacher . As with 1993, Williams's cars were issued numbers 0 and 2, following Prost's victory in

19205-407: The previous year and beat McLaren to second place in the Constructors' Championship, but only won a single race with Schumacher at the Malaysian Grand Prix . Moreover, Montoya was unable to win a single race, despite taking seven pole positions. The Williams team was more competitive in 2003 , as both drivers won on two occasions and Montoya remained in contention for the Drivers' Championship until

19372-455: The rain on lap 29, while Hill went on to his first podium finish: second, 16 seconds behind Senna. Prost won three of the next four Grands Prix for Williams, Senna winning the other race. Prost and Hill later scored a 1–2 in France : the only 1–2 of the season for Williams. Prost won the next two Grands Prix at Silverstone and Hockenheim . Hill proved competitive especially in the second half of

19539-399: The range of rpm where boost is produced, or simplify the layout of the intake/exhaust system. The most common arrangement is twin turbochargers, however triple-turbo or quad-turbo arrangements have been occasionally used in production cars. The key difference between a turbocharger and a supercharger is that a supercharger is mechanically driven by the engine (often through a belt connected to

19706-654: The relationship between Brabham, BMW and Parmalat became strained, Ecclestone was forced to compromise, with Piquet continuing development of the BT50 whilst Patrese raced with the Cosworth chassis. At the Monaco Grand Prix , Patrese won, whilst Piquet was more than two seconds slower in qualifying and retired from the race. The nadir of BMW's Formula One involvement thus far came at the Detroit Grand Prix , where engine reliability problems prevented Piquet from qualifying. BMW's fortunes suddenly improved, however, at

19873-512: The relatively conservative E41, BMW designed the more aggressive P80 engine for 2001 , a basic type number that was maintained for the remainder of the company's involvement in Formula One. The engine immediately proved to have a significant power improvement, and propelled Schumacher and new teammate Juan Pablo Montoya into contention for race victories. In all, the two drivers scored four race wins, but lost other opportunities through unreliability and racing incidents. The FW23 chassis also lacked

20040-523: The remainder of the season. Mansell would get approximately £900,000 per race , while Hill was paid £300,000 for the entire season, though Hill remained as lead driver. Schumacher came back after his suspension for the European Grand Prix , which he won by about 25 seconds, to take a lead of 5 points into the penultimate round in Japan . The race in Japan was held in torrential rain, with Hill managing to win

20207-419: The restarted race, by three seconds on aggregate over Schumacher who finished second. Going into the final round at Adelaide , Schumacher led Hill by a single point. Mansell took pole for Williams but had a poor start which let Hill and Schumacher through to fight for the lead and the 1994 title. Midway through the race, Schumacher's perceived need for a low downforce setup cost him, as he lost control and clipped

20374-436: The rotational force is produced, in order to power the compressor (via a rotating shaft through the center of a turbo). After the exhaust has spun the turbine it continues into the exhaust piping and out of the vehicle. The turbine uses a series of blades to convert kinetic energy from the flow of exhaust gases to mechanical energy of a rotating shaft (which is used to power the compressor section). The turbine housings direct

20541-601: The season finale. BMW also began supplying its engines to the German ATS team this season, but sole driver Manfred Winkelhock was unable to score any points. For 1984 , BMW expanded to three teams by also supplying the M12/13 to Arrows . The team's A7 chassis was not ready at the beginning of the season, and drivers Marc Surer and Thierry Boutsen drove the Cosworth-engined A6 on ten out of 32 entries, but scored three points with BMW engines later in

20708-544: The season the drivers picked up points with a succession of seventh and eighth-place finishes, plus a fourth-place finish for Heidfeld at the Australian Grand Prix . The team ran a radical "twin towers" aero enhancement on the front of the car for the French Grand Prix , which was meant to improve the flow of air over the top of the chassis. The parts were promptly banned by the Fédération Internationale de l'Automobile (FIA) as they were adjudged to impede

20875-522: The season. Mechanical problems cost Hill leads in Britain and Germany, but he went on to win the next three Grands Prix at Hungary , Belgium and Italy which moved him to second in the standings, as well as giving him a chance of taking the Drivers' title. After Italy, Williams would not win a Grand Prix for the rest of the season, as a young Michael Schumacher won the following race in Portugal , and Senna took Japan and Australia to overtake Hill in

21042-445: The sport at the end of 1997 , leaving team owner Frank Williams and Technical Director Patrick Head in need of a new engine partnership to remain competitive. As BMW spent 18 months building and testing a normally aspirated, three-litre V10 engine to comply with technical regulations that had changed significantly since the 1980s, the team used old Renault engines rebadged as first Mecachrome and then Supertec . BMW's E41 engine

21209-399: The sport. The team used Ferrari engines in 2010 . * Excludes factory team. † BMW engine re-badged as Megatron in 1987 and 1988. WilliamsF1 51°37′5″N 1°24′46″W  /  51.61806°N 1.41278°W  / 51.61806; -1.41278 Williams Racing , legally known as Williams Grand Prix Engineering Limited , is a British Formula One team and constructor. It

21376-429: The start of the 1980 season, Regazzoni left the team. So, Carlos Reutemann joined the team. Williams started strong in the championship, with Jones winning the first race of the season in Argentina . Jones won four more races: the French Grand Prix , the British Grand Prix , the Canadian Grand Prix and, the last race of the season, the United States Grand Prix . Jones became the first of seven Williams drivers to win

21543-410: The success he desired. Despite the promise of a new owner, Canadian millionaire Walter Wolf , and the team's rebranding as Wolf–Williams Racing in 1976 , the cars still were not competitive. Eventually, Williams left the rechristened Walter Wolf Racing and moved to Didcot, Oxfordshire to rebuild his team as Williams Grand Prix Engineering. Frank recruited Patrick Head to work for the team, creating

21710-598: The superiority of the FW15C and Williams FW14 B cars that had preceded it. The surprise of testing was Benetton - Ford which was less powerful but more nimble than the Williams. The first four rounds were won by Michael Schumacher in the Benetton - Ford . Senna took pole in the first two races but failed to finish either of them. In the third race, the 1994 San Marino Grand Prix in Imola, Senna again took pole position, but

21877-475: The team 15 points. Williams came second in the Constructors' Championship, scoring 77 points, 64 points behind McLaren. Patrese finished 3rd in the Drivers' Championship with 40 points, 41 points behind second-placed Alain Prost . Boutsen finished 5th in the championship with 37 points after also winning in Australia . Boutsen's win gave Williams the distinction of having won both the first and last Grand Prix of

22044-416: The team Williams signed a contract with tobacco company Rothmans International for 1994 , and their namesake brand became its primary sponsor from 1994 to 1997 . Despite Prost's continued unwillingness to have his former McLaren teammate run with him, pressure from various sources including the team's new sponsor led Williams to agree to terms with Ayrton Senna for 1994. The veto power in Prost's contract

22211-404: The team at the end of the season. The final year of BMW's association with Williams, 2005 , saw the team's decline in competitiveness continue, dropping to fifth in the Constructors' Championship. None of the team's three drivers— Mark Webber , Nick Heidfeld and Antônio Pizzonia —were able to win a race; the team's best result was a double podium finish at the Monaco Grand Prix . By this time,

22378-431: The team remain in F1. On 15 September 2009 it was announced that BMW Sauber had secured a buyer, Qadbak Investments Limited which said to represent European and Middle Eastern interests. However Lotus had been given the 13th and final slot in the 2010 Championship. The team were awarded what was termed a 14th entry, which hinged either on another team dropping out or all the other teams agreeing to allow 28 cars to enter

22545-463: The team's first points since the race in Turkey. Following a meeting of the BMW board on July 28, the company held at press conference the following morning in which it confirmed the team's withdrawal from Formula One at the end of 2009. Chairman Norbert Reithofer described the decision as a strategic one. The Formula One Teams Association released a statement in response pledging its support to help

22712-534: The team's first victory of the season, by almost half a minute over Schumacher's Benetton , while Coulthard would retire due to an electrical problem. In Montreal , both Williams cars finished in the points for the first time that season, with Hill finishing second and Coulthard finishing fifth. In France, Nigel Mansell replaced Coulthard (in the first of four appearances), at the behest of Renault. At Silverstone, Damon Hill accomplished what had eluded his father, twice Formula One World Champion Graham Hill , by winning

22879-502: The team's relationship with its engine supplier had deteriorated, with BMW believing that its engines were capable of winning championships but were being let down by the Williams chassis they were powering. BMW offered to buy the team outright in the hope of gaining overall control of its Formula One endeavours, but Frank Williams refused; as a result, BMW chose to buy the rival Sauber team instead for 2006 and end its deal with Williams. BMW bought Swiss team Sauber in June 2005 to form

23046-400: The technique of using a gear-driven pump to force air into an internal combustion engine. The 1905 patent by Alfred Büchi , a Swiss engineer working at Sulzer is often considered the birth of the turbocharger. This patent was for a compound radial engine with an exhaust-driven axial flow turbine and compressor mounted on a common shaft. The first prototype was finished in 1915 with

23213-411: The third-fastest team, behind Ferrari and McLaren . Theissen also made the point that the performance gap between BMW Sauber and the two top teams was less than the gap between BMW Sauber and the teams behind it. The Canadian Grand Prix brought mixed fortunes for the team. While Heidfeld scored BMW Sauber's best result thus far with a second-place finish, Kubica suffered a huge crash that resulted in

23380-403: The times sheets on occasions. However, team principal Mario Theissen declared some reliability concerns before the season's opening race in Australia . Kubica retired from fourth place with a gearbox problem, but Heidfeld took over the position and held it to the end of the race. In the early races of the season, Heidfeld and Kubica scored a series of points finishes and established BMW Sauber as

23547-500: The turbocharger via a single intake, which causes the gas pulses from each cylinder to interfere with each other. For a twin-scroll turbocharger, the cylinders are split into two groups in order to maximize the pulses. The exhaust manifold keeps the gases from these two groups of cylinders separated, then they travel through two separate spiral chambers ("scrolls") before entering the turbine housing via two separate nozzles. The scavenging effect of these gas pulses recovers more energy from

23714-473: The ultimate downforce to compete with the Ferrari and McLaren drivers at every circuit, although it was the class of the field at "power circuits" such as Hockenheim and Monza . For 2002 , the reliability and consistency of the FW24 chassis was much improved, but Ferrari made a more significant step forward with its own F2002 chassis and dominated both championships. The team scored twelve more points than in

23881-830: The year in favour of McLaren. Unable to make a deal with another major engine manufacturer, Williams used naturally aspirated Judd engines for the 1988 season. This left them with a significant performance deficit compared with their turbo-powered rivals. Piquet left Williams to join Lotus who had retained their Honda engines for the 1988 season, helped by having Satoru Nakajima as number 2 driver to Piquet. Nelson Piquet called Frank Dernie every week to persuade him to join Lotus. Eventually Dernie moved to Lotus to become their new Technical Director. Williams brought in Riccardo Patrese to replace Piquet. The team did not win

24048-500: The year. ATS again failed to score with either Winkelhock or Gerhard Berger , and withdrew from the sport at the end of the season. At the front of the field, Piquet was unable to defend his title, which was dominated by the two McLaren drivers, Niki Lauda and Prost. Piquet took nine pole positions during the season, but retired from the same number of races, and the McLarens were usually faster in race conditions, although he did win

24215-426: Was a deliberate attempt by Schumacher to take Hill out of the race. Others, such as then BBC commentator Murray Walker, defended Schumacher, calling the accident a "racing incident". Meanwhile, Nigel Mansell won the last Grand Prix of his career here, driving the second Williams car. Williams would end the season as Constructors' Champion for the third consecutive year, scoring 118 points, while Hill finished second in

24382-452: Was a major disappointment as the F1.09 chassis proved uncompetitive. Combined with the global financial recession and the company's frustration about the limitations of the contemporary technical regulations in developing technology relevant to road cars, BMW chose to withdraw from the sport, selling the team back to its founder, Peter Sauber . The early years of the post-war World Drivers' Championship saw private BMW racing cars, based on

24549-456: Was a record until Ferrari won its tenth championship in 2000 . Notable drivers for Williams include: Alan Jones , Keke Rosberg , Nigel Mansell , Damon Hill , David Coulthard , Jenson Button , Juan Pablo Montoya , Alain Prost , Nelson Piquet , Ayrton Senna , Riccardo Patrese , Valtteri Bottas , Carlos Reutemann , Felipe Massa and Jacques Villeneuve . Of these drivers, Jones, Rosberg, Mansell, Hill, Piquet, Prost, and Villeneuve won

24716-423: Was also one of the first Formula One cars to feature onboard telemetry as a means of monitoring the engine's fuel injection. The team's lead driver, Nelson Piquet , tested the BT50 throughout 1981, but the car proved chronically unreliable until Bosch introduced a digital electronic management system at the end of the year, which immediately improved the situation. The BT50 made a solitary race weekend appearance at

24883-581: Was followed by a second place in 2007 after the McLaren team had been excluded from the championship. Robert Kubica took the team's only Grand Prix victory at the 2008 Canadian Grand Prix . Following a poor 2009 season, BMW withdrew from Formula One and sold the team back to founder Peter Sauber . For the 2006 season , BMW Sauber signed Nick Heidfeld from Williams to be the lead driver, while 1997 World Champion Jacques Villeneuve had his existing two-year contract with Sauber honoured. Robert Kubica

25050-431: Was forced to retire. Heidfeld then secured the team's first podium of the year in Malaysia , but after 6 races BMW Sauber had collected a mere 6 points, and occupied 8th place in the Constructors' Championship out of 10 teams. A raft of upgrades were set for Turkey , including an improved regenerative braking system (KERS) and a double deck diffuser. While the new diffuser was implemented, the KERS could not be made to fit

25217-524: Was founded by Frank Williams (1942–2021) and 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). The team is based in Grove, Oxfordshire , on a 60-acre (24 ha) site. 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

25384-417: Was involved in a fatal crash at the second corner after completing six laps. The repercussions of Senna's fatal accident were severe for the team itself, as the Italian prosecutors tried to charge the team and Frank Williams with manslaughter, an episode which was not over until 2005. At the next race in Monaco , Damon Hill was the only Williams on the grid, as a mark of respect to Senna, and retired on

25551-447: Was joined at the team by Clay Regazzoni . It was not until the seventh round of the championship, the Monaco Grand Prix , that they finished in the points. Regazzoni came close to taking the team's first win but finished second, less than a second behind race winner Jody Scheckter . The next race, the French Grand Prix , is remembered for the final lap battle between René Arnoux and Gilles Villeneuve , but also saw both cars finish in

25718-496: Was later disqualified for circumventing the minimum weight limit by running "water-cooled brakes". Both drivers also raced the BT49 at the Long Beach Grand Prix , and the team boycotted the San Marino Grand Prix as part of the ongoing FISA–FOCA war . For the following race, the Belgian Grand Prix , Piquet and Patrese switched back to the BT50, but Piquet finished three laps behind the winner and Patrese retired. As

25885-412: Was leaving CART to replace Berger at McLaren. McLaren also was potentially dealing with losing a driver, as Ayrton Senna's contract had expired following the 1992 season. In addition to this, McLaren's arrangement with Honda to provide engines had also expired, and the team had signed to run Ford engines for 1993. With McLaren having fallen behind Williams on the grid, combined with his uncertainty regarding

26052-629: Was looking to bring Prost aboard. Prost and Gerhard Berger had essentially swapped rides after the 1989 season with Prost becoming Mansell's teammate at Ferrari. The acrimonious relationship between the two that ensued nearly resulted in Mansell retiring from the sport altogether and he had not forgotten this; as such, Mansell began looking for other options to continue his racing career. He eventually decided to move over to CART, where he paired with Mario Andretti at Newman/Haas Racing . That seat, meanwhile, had opened up because Andretti's son, Michael ,

26219-429: Was not issued; instead, the team was issued the number 0, which was placed on Hill's car, while Prost was issued number 2. 1993 marked the final season that Williams ran with Canon as its primary backer. During the 1994 season, Williams used FW16 (developed during the pre-season) and FW16B (with shorter sidepods and optimised for the revised floor regulations which were introduced during the season). After Canon left

26386-627: Was one driven by an engine in the rear of the car (known as the "Heck", the German automotive term for "back" or "rear"), a design feature which became standard in Formula One in the early 1960s after later success by the Cooper team. In the 1960s, the Formula One German Grand Prix was often held concurrently with a Formula Two race on the same circuit, allowing BMW F2 cars to take part. In 1967 , BMW entered Hubert Hahne in

26553-409: Was only in effect for the 1993 season, and since Williams was now free to do as it desired and that Senna was again a free agent, the team decided it would bring in the multi-time former champion. To appease Prost, who decided to retire from racing permanently after Senna's signing, Williams agreed to pay him his full salary for the second half of the contract. Given this was the same team that had won

26720-545: Was ready to compete in the 2000 season , fitted in the FW22 and driven by Ralf Schumacher and Jenson Button . Schumacher scored a podium finish in the engine's first race, and added two more during the course of the season. A series of consistent points-scoring finishes meant that Williams finished a competitive third in the Constructors' Championship, some distance behind the dominant Ferrari and McLaren teams, but ahead of engine manufacturers with more recent experience. After

26887-650: Was signed as the team's third driver . The team continued to use Sauber's facilities, mostly for chassis construction and wind tunnel testing, while BMW's headquarters in Munich were responsible for building the new 2.4-litre P86 V8 engine , revised technical regulations forcing a change from the 3-litre V10 formula. This replaced the Petronas -badged Ferrari engines which the team had used since 1997. The Sauber team's existing major sponsors, Petronas and Credit Suisse , renewed their contracts with BMW. The team also announced

27054-589: Was sold to GKN . 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. Frank and Claire Williams stepped down from being Manager and Deputy Manager of the team on 6 September 2020, with the 2020 Italian Grand Prix being their last time in their respective positions. Frank Williams founded Williams in 1977 after his previous team, Frank Williams Racing Cars , failed to achieve

27221-550: Was still unreliable, though, restricting Piquet and Patrese to just four further finishes before the end of the season. The BMW engine's competitiveness was shown by the fact that Piquet retired from the lead of the British , French and German Grands Prix, whilst Patrese likewise retired from the lead of the Austrian Grand Prix . Patrese also secured BMW's first fastest lap at the French Grand Prix, whilst Piquet took

27388-409: Was that he was recovering from his previous accident, but the team later announced that the driver change was permanent. Kubica scored BMW Sauber's second podium finish of the season at the Italian Grand Prix , after running in third place for most of the race and leading briefly during the first round of pit stops while Heidfeld finished in eighth. The team scored a total of 36 points to finish fifth in

27555-452: Was thus with the new Benetton team, which scored 19 points, won the Mexican Grand Prix and took two pole positions with Berger and Teo Fabi. Arrows and Benetton continued to use the original "upright" version of the M12/13 engine. BMW reduced its full works commitment to the sole supply of Brabham in 1987 ; the team produced the more conservative BT56 chassis and scored ten points with Patrese, Andrea de Cesaris and Stefano Modena . At

27722-506: Was to significantly reduce the car's drag and lower its centre of gravity. BMW produced the M12/13/1 engine, which was tilted sideways to fit in the reduced space allocated to the engine. Despite its theoretical advantages, the BT55 proved uncompetitive, suffering from poor traction and numerous mechanical failures caused by oil scavenge problems in the tilted engine. Moreover, the team suffered

27889-696: Was used by the German Ministry of Transport for two large passenger ships called the Preussen and Hansestadt Danzig . The design was licensed to several manufacturers and turbochargers began to be used in marine, railcar and large stationary applications. Turbochargers were used on several aircraft engines during World War II, beginning with the Boeing B-17 Flying Fortress in 1938, which used turbochargers produced by General Electric. Other early turbocharged airplanes included
