106-493: The Brabham BT46 is a Formula One racing car designed by Gordon Murray for the Brabham team, owned by Bernie Ecclestone , for the 1978 Formula One season . The car featured several radical design elements, one of which was the use of flat panel heat exchangers on the bodywork of the car to replace conventional water and oil radiators . It was removed before the car's race debut, never to be seen again. The cars, powered by
212-400: A flat-12 Alfa Romeo engine, raced competitively with modified nose-mounted radiators for most of the year, driven by Niki Lauda and John Watson , winning one race in this form and scoring sufficient points for the team to finish third in the constructors' championship. The "B" variant of the car, also known as the "fan car", was introduced at the 1978 Swedish Grand Prix as a counter to
318-486: A rev limiter . The Formula One Teams Association (FOTA) believed that allowing some teams to have such technical freedom would have created a 'two-tier' championship, and thus requested urgent talks with the FIA. But talks broke down and FOTA teams announced, with the exception of Williams and Force India , that 'they had no choice' but to form a breakaway championship series . On 24 June, Formula One's governing body and
424-627: A ban on ground-effect aerodynamics during 1983 . But by then, turbocharged engines, which Renault had pioneered in 1977 , were producing over 520 kW (700 bhp) and were essential to be competitive. By 1986 , a BMW turbocharged engine achieved a flash reading of 5.5 bar (80 psi) pressure, estimated to be over 970 kW (1,300 bhp) in qualifying for the Italian Grand Prix . The next year, power in race trim reached around 820 kW (1,100 bhp), with boost pressure limited to only 4.0 bar. These cars were

The number of cars eliminated in each period is dependent on the total number of cars entered into the championship. Currently, with 20 cars, Q1 runs for 18 minutes, and eliminates the slowest five drivers. During this period, any driver whose best lap takes longer than 107% of
636-482: A guerrilla war with a very long-term aim in view". FOCA threatened to establish a rival series and boycotted a Grand Prix, and FISA withdrew its sanction from races. The result was the 1981 Concorde Agreement , which guaranteed technical stability, as teams were to be given reasonable notice of new regulations. Although FISA asserted its right to the TV revenues, it gave FOCA the administration of those rights. FISA imposed
742-404: A management buyout to become Brawn GP , with Ross Brawn and Nick Fry running and owning the majority of the organisation. Brawn GP laid off hundreds of employees, but won the year's world championships. BMW F1 was bought out by the original founder of the team, Peter Sauber . The Lotus F1 Team was another, formerly manufacturer-owned team that reverted to "privateer" ownership, together with
848-468: A new Concorde Agreement committing them to the sport until 2025, including a $ 145 million budget cap for car development to support equal competition and sustainable development. The COVID-19 pandemic forced the sport to adapt to budgetary and logistical limitations. A significant overhaul of the technical regulations intended to be introduced in the 2021 season was pushed back to 2022, with constructors instead using their 2020 chassis for two seasons and
954-530: A number of Grand Prix racing organisations made suggestions for a new championship to replace the European Championship, but due to the suspension of racing during the conflict, the new International Formula for cars did not become formalised until 1946, to become effective in 1947. The new World Championship was instituted to commence in 1950 . The first world championship race, the 1950 British Grand Prix , took place at Silverstone Circuit in
1060-404: A partnership with Lego , with the first new sets releasing in 2025. The regulations governing Formula One are set to be revised for the 2026 season, with big changes planned to help encourage closer and more competitive racing. Changes include: In November 2024, General Motors reached an agreement to enter Formula 1 in 2026 with its Cadillac brand. A Formula One Grand Prix event spans
1166-470: A press release stating it had been informed it was not entered for the 2010 season, and an FIA press release said the FOTA representatives had walked out of the meeting. On 1 August, it was announced FIA and FOTA had signed a new Concorde Agreement, bringing an end to the crisis and securing the sport's future until 2012. To compensate for the loss of manufacturer teams, four new teams were accepted entry into

#17327809126041272-516: A reason to impose rule changes that otherwise, under the Concorde Agreement, would have had to be agreed upon by all the teams—most notably the changes introduced for 1998 . This so-called 'narrow track' era resulted in cars with smaller rear tyres, a narrower track overall, and the introduction of grooved tyres to reduce mechanical grip. The objective was to reduce cornering speeds and produce racing similar to rainy conditions by enforcing
1378-434: A season (13, since beaten by Max Verstappen ), and most Drivers' Championships (seven, tied with Lewis Hamilton as of 2021). Schumacher's championship streak ended on 25 September 2005, when Renault driver Fernando Alonso became Formula One's youngest champion at that time (until Lewis Hamilton in 2008 and followed by Sebastian Vettel in 2010 ). During 2006, Renault and Alonso won both titles again. Schumacher retired at
1484-413: A series of races, known as Grands Prix . Grands Prix take place in multiple countries and continents on either purpose-built circuits or closed roads. A point-system is used at Grands Prix to determine two annual World Championships: one for the drivers , and one for the constructors (the teams). Each driver must hold a valid Super Licence , the highest class of racing licence the FIA issues, and
1590-442: A smaller contact patch between tyre and track. According to the FIA, this was to reduce cornering speeds in the interest of safety. Results were mixed, as the lack of mechanical grip resulted in the more ingenious designers clawing back the deficit with aerodynamic grip. This resulted in pushing more force onto the tyres through wings and aerodynamic devices, which in turn resulted in less overtaking, as these devices tended to make
1696-427: A token system limiting which parts could be modified introduced. The start of the 2020 season was delayed by several months, and both it and 2021 seasons were subject to several postponements, cancellations, and rescheduling of races due to shifting restrictions on international travel. Many races took place behind closed doors and with only essential personnel present to maintain social distancing . In 2022,
1802-403: A weekend. It typically begins with two free practice sessions on Friday, and one free practice session on Saturday. Additional drivers (commonly known as third drivers ) are allowed to run on Fridays, but only two cars may be used per team, requiring a race driver to give up their seat. A qualifying session is held after the last free practice session. This session determines the starting order for
1908-399: A world championship race. It entered the 1961 British Grand Prix , the only front-engined car to compete that year. During 1962 , Lotus introduced a car with an aluminium-sheet monocoque chassis instead of the traditional space-frame design. This proved to be the greatest technological breakthrough since the introduction of mid-engined cars. In 1968 , sponsorship was introduced to
2014-559: Is allocated one set of the softest tyres for use in Q3. The cars that qualify for Q3 must return them after Q3; the cars that do not qualify for Q3 can use them during the race. As of 2022, all drivers are given a free choice of tyre to use at the start of the Grand Prix, whereas in previous years only the drivers that did not participate in Q3 had free tyre choice for the start of the race. Any penalties that affect grid position are applied at
2120-505: Is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of racing since its inaugural running in 1950 . The word formula in the name refers to the set of rules all participants' cars must follow. A Formula One season consists of
2226-434: The 1955 Le Mans disaster . The first major technological development in the sport was Bugatti 's introduction of mid-engined cars. Jack Brabham , the world champion in 1959 , 1960 , and 1966 , soon proved the mid-engine's superiority over all other engine positions. By 1961 all teams had switched to mid-engined cars. The Ferguson P99 , a four-wheel drive design, was the last front-engined Formula One car to enter
SECTION 20
#17327809126042332-457: The 2002 Austrian Grand Prix . Other changes included the qualifying format, the point-scoring system, the technical regulations, and rules specifying how long engines and tyres must last. A 'tyre war' between suppliers Michelin and Bridgestone saw lap times fall, although, at the 2005 United States Grand Prix at Indianapolis, seven out of ten teams did not race when their Michelin tyres were deemed unsafe for use, leading to Bridgestone becoming
2438-403: The 2014 Japanese Grand Prix , where Jules Bianchi collided with a recovery vehicle after aquaplaning off the circuit, dying nine months later from his injuries. Since 1994, three track marshals have died, one at the 2000 Italian Grand Prix , one at the 2001 Australian Grand Prix and one at the 2013 Canadian Grand Prix . Since Senna's and Ratzenberger's deaths, the FIA has used safety as
2544-425: The 2017 and 2018 seasons featured a title battle between Mercedes and Ferrari. Mercedes ultimately won the titles with multiple races to spare and continued to dominate in the next two years, eventually winning seven consecutive Drivers' Championships from 2014 to 2020 and eight consecutive Constructors' titles from 2014 to 2021. During this eight-year period between 2014 and 2021, a Mercedes driver won 111 of
2650-603: The Alfa Romeo name, Sauber introduced a title partnership with the online casino Stake.com , resulting in the team's new identity as Stake F1 Team Kick Sauber . Sauber will hold Stake's sponsorship name until the end of 2025, after which it will become the Audi works team for the 2026 season onwards. Scuderia AlphaTauri , Red Bull's junior team, dropped its name and took on sponsors from Hugo Boss and Cash App, becoming Visa Cash App RB, or VCARB for 2024. Formula One announced
2756-632: The Commission Sportive Internationale intervened to declare that henceforth fan cars would not be allowed and the car never raced again in Formula One. The car was not considered to have been illegal when it raced however, so the Swedish Grand Prix win stood. The two converted chassis were returned to standard BT46 configuration for the next race. A BT46 competed in 'B' specification once again in 1979 in
2862-467: The Cosworth DFV engines used by most teams, as well as a peak 324 lb-ft of torque (439 N·m). However the power came at the expense of greater size, increased fuel and oil consumption and about 40 kg more weight. The engine was also difficult to work with, with significant variations in dimensions between units. The car used a revised and lighter version of the 6-speed gearbox designed for
2968-694: The Formula One Constructors Association (FOCA) since 1972 and became its president during 1978. According to Ecclestone's biographer Terry Lovell, the heads of the other FOCA teams, led by Colin Chapman threatened to withdraw their support for Ecclestone unless he withdrew the BT46B. Ecclestone negotiated a deal within FOCA whereby the car would have continued for another three races before Brabham would voluntarily withdraw it. However,
3074-500: The Grand Prix Manufacturers Association (GPMA), the manufacturers negotiated a larger share of Formula One's commercial profit and a greater say in the running of the sport. In 2008 and 2009, Honda , BMW , and Toyota all withdrew from Formula One racing within a year, blaming the economic recession . This resulted in the end of manufacturer dominance of the sport. The Honda F1 team went through
3180-565: The Gunnar Nilsson Trophy race at Donington Park . This was an event held to raise funds for the Gunnar Nilsson Cancer Fund. Originally intended as a non-championship Formula One race, without FIA sanction it was instead run in a time trial format, with victory going to the fastest single lap recorded. As it was not an FIA event, the car's illegality was not a factor. Nelson Piquet drove, coming fourth of
3286-655: The Imperial Tobacco 's Gold Leaf livery at the 1968 Spanish Grand Prix . Aerodynamic downforce slowly gained importance in car design with the appearance of aerofoils during the 1968 season. The wings were introduced by Lotus's owner Colin Chapman who installed modest front wings and a rear spoiler on his Lotus 49 B at the 1968 Monaco Grand Prix . In the late 1970s, Lotus introduced ground-effect aerodynamics, previously used on Jim Hall 's Chaparral 2J in 1970, that provided enormous downforce and greatly increased cornering speeds. The aerodynamic forces pressing

3392-509: The Italian Grand Prix in the standard car, albeit after Mario Andretti and Gilles Villeneuve were penalised a minute for jumping the second race start after Ronnie Peterson ’s fatal accident at the first start. The BT46 appeared for the last time in the Formula One World Championship at the first round of the 1979 season in the hands of Nelson Piquet . Niki Lauda also used the car to qualify for that race, as
3498-531: The Jaguar Racing team, new manufacturer-owned teams entered Formula One for the first time since Alfa Romeo's and Renault's departures in 1985. By 2006, the manufacturer teams—Renault, BMW , Toyota , Honda, and Ferrari—dominated the championship, taking five of the first six places in the Constructors' Championship. The exception was McLaren, which at the time was part-owned by Mercedes-Benz. Through
3604-505: The World Manufacturers' Championship ( 1925 – 1930 ) and European Drivers' Championship ( 1931 – 1939 ). The formula is a set of rules that all participants' cars must follow. Formula One was a formula agreed upon in 1946 to officially become effective in 1947 . The first Grand Prix in accordance with the new regulations was the 1946 Turin Grand Prix , anticipating the formula's official start. Before World War II ,
3710-409: The 'sprint shootout'; such a system made its debut at the 2023 Azerbaijan Grand Prix and is set to be used throughout all sprint sessions in place of the traditional second free practice session. Sprint qualifying sessions are run much shorter than traditional qualifying, and each session required teams to fit new tyres - mediums for SQ1 and SQ2, and softs for SQ3 - otherwise they cannot participate in
3816-585: The 160 races, with Hamilton winning 81 of these and taking six Drivers' Championships during this period to equal Schumacher's record of seven titles. In 2021 , the Honda-powered Red Bull team began to seriously challenge Mercedes, with Verstappen beating Hamilton to the Drivers' Championship after a season-long battle that saw the pair exchange the championship lead multiple times. This era has seen an increase in car manufacturer presence in
3922-538: The 2010 season ahead of a much anticipated 'cost-cap'. Entrants included a reborn Team Lotus —led by a Malaysian consortium including Tony Fernandes , the boss of Air Asia ; Hispania Racing —the first Spanish Formula One team; and Virgin Racing — Richard Branson 's entry into the series following a successful partnership with Brawn the year before. They were also joined by the US F1 Team , which planned to run out of
4028-561: The 2010 season, Mercedes-Benz reentered the sport as a manufacturer after it purchased Brawn GP and split with McLaren after 15 seasons with the team. During the 2009 season, Formula One was gripped by the FIA–FOTA dispute . FIA President Max Mosley proposed numerous cost-cutting measures for the next season, including an optional budget cap for the teams; teams electing to take the budget cap would be granted greater technical freedom, adjustable front and rear wings, and an engine not subject to
4134-473: The BT45B. Brabham designed the gearbox casing, which was cast by Alfa Romeo and used Hewland gears. The BT46 was an aluminium alloy monocoque featuring the trapezoidal cross section common to many of Gordon Murray's 1970s designs. It featured inbuilt pneumatic jacks fed from an external supply of compressed air to lift it off the ground for tyre changes during practice. It employed a very early version of
4240-494: The F1 governing body announced a major rule and car design change intended to promote closer racing through the use of ground effects , new aerodynamics, larger wheels with low-profile tyres, and redesigned nose and wing regulations. Red Bull emerged as the dominant force after the rule shakeup. The 2022 and 2023 Constructors' and Drivers' Championships were won by Red Bull and Verstappen, with multiple races to spare. In 2023
4346-539: The FIA had ruled it could be used for the remainder of that season. Murray, Brabham's chief designer, later said that the car was withdrawn by Brabham due to concerns from Bernie Ecclestone, the team owner. Ecclestone became chief executive of the Formula One Constructors' Association (FOCA) in the same year that the Brabham BT46 appeared, and he was concerned that the upset from other teams over

4452-421: The FIA opened applications for new teams to enter Formula 1 in the then near future. Of the teams that applied, only Andretti were approved by the FIA, with them then being rejected by Formula One Management , though they have launched an appeal. In early 2024, the Formula One landscape underwent a significant change in the sphere of team sponsorships and collaborations. Having competed for five seasons under
4558-568: The Type 78, but by early 1978, Gordon Murray had grasped how the Lotus design was achieving its remarkable levels of grip. He also realised that the Alfa Romeo flat-12 engine used by Brabham that season was too wide to permit the Venturi tunnels needed for really significant ground effect. At Murray's instigation, Alfa went on to produce a V12 engine for the 1979 season. In the meantime, Murray's idea
4664-650: The UK in the 1960s and 1970s. Promoters held non-championship Formula One events for many years. Due to the increasing cost of competition, the last of these was held in 1983. This era featured teams managed by road-car manufacturers, such as Alfa Romeo, Ferrari, Mercedes-Benz and Maserati . The first seasons featured prewar cars like Alfa Romeo's 158 , which were front-engined , with narrow tyres and 1.5-litre supercharged or 4.5-litre naturally aspirated engines. The 1952 and 1953 seasons were run to Formula Two regulations, for smaller, less powerful cars, due to concerns over
4770-524: The United Kingdom on 13 May 1950. Giuseppe Farina , competing for Alfa Romeo , won the first Drivers' World Championship, narrowly defeating his teammate Juan Manuel Fangio . Fangio won the championship in 1951 , 1954 , 1955 , 1956 , and 1957 . This set the record for the most World Championships won by a single driver, a record that stood for 46 years until Michael Schumacher won his sixth championship in 2003. A Constructors' Championship
4876-557: The United States as the only non-European-based team in the sport. Financial issues befell the squad before they even made the grid. Despite the entry of these new teams, the proposed cost-cap was repealed and these teams—which did not have the budgets of the midfield and top-order teams—ran around at the back of the field until they collapsed; HRT in 2012, Caterham (formerly Lotus) in 2014 and Manor (formerly Virgin, then Marussia), having survived falling into administration in 2014, at
4982-736: The ambitious design of the BT46. It was intended to compensate for the weight of the engine and fuel and allow the Brabham team to take a large technical step forward as well as to improve safety. Alfa Romeo's sportscar-derived flat-12 engine had a capacity of 2995 cc and employed fuel injection and electronic ignition . The engine featured a cast magnesium alloy engine block with aluminium alloy crankcase and magnesium or aluminium cylinder heads . There were four gear-driven valves per cylinder. In Formula One form by 1978 it delivered about 520 bhp at 12,000 rpm, about 50 bhp more than
5088-406: The average annual cost of running a team—designing, building, and maintaining cars, pay, transport—at approximately £220,000,000 (or $ 265,000,000), Formula One's financial and political battles are widely reported. The Formula One Group is owned by Liberty Media , which acquired it in 2017 from private-equity firm CVC Capital Partners for £6.4 billion ($ 8 billion). Formula One originated from
5194-867: The ban on driver aids was in name only, as they "proved difficult to police effectively". The teams signed a second Concorde Agreement in 1992 and a third in 1997. On the track, the McLaren and Williams teams dominated the 1980s and 1990s. Brabham was also competitive during the early 1980s, winning two Drivers' Championships with Nelson Piquet . Powered by Porsche , Honda , and Mercedes-Benz , McLaren won 16 championships (seven constructors' and nine drivers') in that period, while Williams used engines from Ford , Honda, and Renault to also win 16 titles (nine constructors' and seven drivers'). The rivalry between racers Ayrton Senna and Alain Prost became F1's central focus during 1988 and continued until Prost retired at
5300-636: The buy-out of the Renault team by Genii Capital investors. But a link with its previous owners still survived, with its car continuing to be powered by a Renault engine until 2014. McLaren also announced that it was to reacquire the shares in its team from Mercedes-Benz (McLaren's partnership with Mercedes was reported to have started to sour with the McLaren Mercedes SLR road car project and tough F1 championships, which included McLaren being found guilty of spying on Ferrari ). Hence, during
5406-399: The car, they could accelerate the air passing under the car, thereby reducing the air pressure under the car relative to that over it and pushing the tyres down harder onto the track. The increased downforce gave more grip and thus higher cornering speeds. Ground effect had the great advantage of being a low drag solution, unlike conventional wings, meaning that the increased cornering ability
SECTION 50
#17327809126045512-505: The carbon brakes that were in universal use by the mid-1980s—a concept taken from the aircraft industry. The system, which Brabham had been developing since 1976, combined carbon composite brake pads with a steel disc faced with carbon composite pucks. The most radical feature of the original car was its use of flat plate heat exchangers mounted flush to the surface of the bodywork in place of conventional water radiators. The absence of standard radiators allowed Murray to compensate somewhat for
5618-403: The cars to the track were up to five times the car's weight. As a result, extremely stiff springs were needed to maintain a constant ride height , leaving the suspension virtually solid. This meant that the drivers depended entirely on the tyres for any small amount of cushioning of the car and driver from irregularities of the road surface. Beginning in the 1970s, Bernie Ecclestone rearranged
5724-408: The cars was soon protested, but they were allowed to race. They qualified second and third behind championship leader Andretti. In the race, Watson spun off on the 19th lap. Once the slower Didier Pironi dropped oil onto the track and with both major front-runners out of the race, the remaining Brabham was in a class of its own, seemingly unaffected by the slippery surface. Lauda passed Andretti around
5830-527: The championship began in 1950 . This was the debut race of the future world champion Keke Rosberg . The Ferrari ( 312T3 ) and Brabham ( BT46 ) teams had new cars in Kyalami for the race. The event also saw the return of Renault with its unique turbocharged car. Ronnie Peterson , in the Lotus 78 with its Colin Chapman -inspired ground effect aerodynamics, battled Patrick Depailler in his Tyrrell on
5936-456: The dearth of Formula One cars. When a new Formula One formula for engines limited to 2.5 litres was reinstated for the 1954 world championship, Mercedes-Benz introduced its W196 , which featured things never seen on Formula One cars before, such as desmodromic valves , fuel injection , and enclosed streamlined bodywork. Mercedes drivers won the championship for the next two years, before the team withdrew from all motorsport competitions due to
6042-510: The dominant ground effect Lotus 79 . The BT46B generated an immense amount of downforce utilizing a fan, claimed to be for increased cooling, but which also extracted air from beneath the car. The car only raced once in this configuration in the Formula One World Championship—when Niki Lauda won the 1978 Swedish Grand Prix at Anderstorp . The "fan car" concept was withdrawn by Brabham after one race even though
6148-405: The driver to very high lateral acceleration, which would become a major problem in the ground effect era. In his autobiography, Lauda described the car as being unpleasant to drive due to the lateral loads and reliance on aerodynamics over driver skill. He realised early on that the rate of ground effect development meant that in the future, every driver would be exposed to such g-loading while behind
6254-409: The end of 1993 . Senna died at the 1994 San Marino Grand Prix after crashing into a wall on the exit of the notorious curve Tamburello . The FIA worked to improve the sport's safety standards since that weekend, during which Roland Ratzenberger also died in an accident during Saturday qualifying. No driver died of injuries sustained on the track at the wheel of a Formula One car for 20 years until
6360-541: The end of 2006 after 16 years in Formula One, but came out of retirement for the 2010 season, racing for the newly formed Mercedes works team, following the rebrand of Brawn GP . During this period, FIA frequently changed the championship rules with the intention of improving the on-track action and cutting costs. Team orders , legal since the championship started during 1950, were banned during 2002, after several incidents in which teams openly manipulated race results, generating negative publicity, most famously by Ferrari at
6466-439: The end of 2016. A major rule shakeup in 2014 saw the 2.4-litre naturally aspirated V8 engines replaced by 1.6-litre turbocharged hybrid power units. This prompted Honda to return to the sport in 2015 as the championship's fourth power unit manufacturer. Mercedes emerged as the dominant force after the rule shakeup, with Lewis Hamilton winning the championship closely followed by his main rival and teammate, Nico Rosberg , with
SECTION 60
#17327809126046572-490: The end of qualifying. Grid penalties can be applied for driving infractions in the previous or current Grand Prix, or for changing a gearbox or engine component. If a car fails scrutineering, the driver will be excluded from qualifying but will be allowed to start the race from the back of the grid at the race stewards' discretion. 2021 saw the trialling of a 'sprint qualifying' race on the Saturday of three race weekends, with
6678-585: The engine. Using a fan to assist cooling was legal—Brabham had used a small electric fan to this effect on the BT45Cs at the South American races at the start of the year—and Brabham claimed that this was the primary effect of the new device. These claims were lent some legitimacy by the cooling system issues that had affected the original design at the start of the year. The cars were modified BT46s—chassis numbers BT46/4 and BT46/6. Modifications to implement
6784-622: The fan car could collapse FOCA. Murray said in 2008 that Ecclestone "was working on getting his foothold in the Formula One Constructors’ Association and launching himself towards what he's doing now", with the words "what he's doing now" referring to Ecclestone's position as chief executive of the Formula One Group , which he held from 1987 until 2017. The first Alfa Romeo-engined Brabham, the Brabham BT45
6890-410: The fan concept were quite extensive—involving sealing the engine bay as well as adding the clutch system and the fan. They were designed and tested in some secrecy. Brabham's lead driver, Niki Lauda, realised he had to adjust his driving style, mostly for cornering. He found that if he accelerated around corners, the car would "stick" to the road as if it were on rails. This had the side effect of exposing
6996-417: The faster the engine ran, the stronger the suction effect. Like the Lotus, it had sliding "skirts" that sealed the gap between the sides of the cars and the ground. These prevented excessive air from being sucked into the low pressure area under the car and dissipating the ground effect. There was a rule banning "moveable aerodynamic devices", but the fan also drew air through a horizontally mounted radiator over
7102-466: The fastest getting first place on the grid, referred to as pole position . From 1996 to 2002, the format was a one-hour shootout. This approach lasted until the end of 2002 before the rules were changed again because the teams were not running in the early part of the session to take advantage of better track conditions later on. Grids were generally limited to 26 cars – if the race had more entries, qualification would also decide which drivers would start
7208-511: The fastest time in Q1 will not be allowed to start the race without permission from the stewards. Otherwise, all drivers proceed to the race albeit in the worst starting positions. This rule does not affect drivers in Q2 or Q3. In Q2, the 15 remaining drivers have 15 minutes to set one of the ten fastest times and proceed to the next period. Finally, Q3 lasts 12 minutes and sees the remaining ten drivers decide
7314-489: The first ten grid positions. At the beginning of the 2016 Formula 1 season, the FIA introduced a new qualifying format, whereby drivers were knocked out every 90 seconds after a certain amount of time had passed in each session. The aim was to mix up grid positions for the race, but due to unpopularity, the FIA reverted to the above qualifying format for the Chinese GP, after running the format for only two races. Each car
7420-508: The five cars competing. Murray had designed a car for the 1979 season called the BT47 that had a Chaparral 2J -type box rear end with twin variable geometry fans on the rear to maximize ground effect. The car was never built due to the FIA closing the loophole in the regulations for the 1979 season. Another variation on the theme was produced later in the season. Like the BT46B, the BT46C removed
7526-498: The front of the car. The BT46 debuted at the third race of the 1978 season, the South African Grand Prix on 4 March 1978, with the revised nose-mounted radiators. The cars were immediately competitive, although reliability was suspect. After the winning debut and subsequent withdrawal of the BT46B "fan car" at the Swedish Grand Prix, the Brabham team completed the season with the standard BT46s. Niki Lauda winning
7632-475: The intention of testing the new approach to qualifying. The traditional qualifying would determine the starting order for the sprint, and the result of the sprint would then determine the start order for the Grand Prix. The system returned for the 2022 season, now titled the 'sprint'. From 2023, sprint races no longer impacted the start order for the main race, which would be determined by traditional qualifying. Sprints would have their own qualifying session, titled
7738-410: The large engine and fuel tanks and produce a relatively light design with a low frontal cross section (important to reduce drag). Upon seeing pictures of the car, consultant engineer David Cox calculated that the BT46 had only around 30% of the cooling surface area required. He contacted Brabham to express his concerns. By this time the car had already run, suffering serious problems with over-heating. Cox
7844-474: The last lap to take a dramatic victory. John Watson finished third for Brabham. Young Italian, Riccardo Patrese got his Arrows into the lead before retiring with a blown engine. Pole sitter and reigning world champion Niki Lauda , in his first season with Brabham, retired with engine failure and the Ferraris of Carlos Reutemann and Gilles Villeneuve exited on lap 55. James Hunt , who had qualified third on
7950-434: The management of Formula One's commercial rights; he is widely credited with transforming the sport into the multibillion-dollar business it now is. When Ecclestone bought the Brabham team during 1971, he gained a seat on the Formula One Constructors' Association , and in 1978, he became its president. Previously, the circuit owners controlled the income of the teams and negotiated with each individually; Ecclestone persuaded
8056-458: The most powerful open-wheel circuit racing cars ever. To reduce engine power output and thus speeds, the FIA limited fuel tank capacity in 1984 , and boost pressures in 1988 , before banning turbocharged engines completely in 1989 . The development of electronic driver aids began in the 1980s. Lotus began to develop a system of active suspension , which first appeared during 1983 on the Lotus 92 . By 1987, this system had been perfected and
8162-404: The new BT48 was proving troublesome, although he did race the new car. Piquet retired on the first lap after a multi-car collision that wrecked the BT46. Lotus had introduced the concept of ground effect to the Formula One world championship in 1977 with their fast, but not always reliable, Type 78 . Peter Wright and Colin Chapman had discovered that by carefully shaping the underside of
8268-411: The outside of one of the corners, who dropped out shortly afterwards due to a broken valve, and went on to win by over half a minute from Riccardo Patrese in an Arrows . There was uproar from rival teams, who saw the "fan car" as a threat to their competitiveness. Lotus immediately started design work on a fan version of the 79. Bernie Ecclestone , owner of the Brabham team, had also been secretary of
8374-441: The overall layout for the car, utilising the cooling properties of the fan to be able to argue that this was its primary purpose, thus satisfying the regulations. Gordon Murray designed a version driven by a complex series of clutches running from the engine to a large single fan at the back of the car, anticipating problems caused by the momentum of the fan during gear changes, although in practice these were not required. Therefore,
8480-477: The pit crews time to clear themselves and their equipment from the grid for the race start. 1978 South African Grand Prix The 1978 South African Grand Prix (formally the XXIV Citizen and Asseng Grand Prix of South Africa ) was a Formula One motor race held on 4 March 1978 at Kyalami . It was the third round of the 1978 Formula One season and the 300th World Championship Grand Prix held since
8586-426: The race on Sunday. Each driver may use no more than thirteen sets of dry-weather tyres, four sets of intermediate tyres, and three sets of wet-weather tyres during a race weekend. For much of the sport's history, qualifying sessions differed little from practice sessions; drivers would have one or more sessions in which to set their fastest time, with the grid order determined by each driver's best single lap, with
8692-461: The race. During the early 1990s, the number of entries was so high that the worst-performing teams had to enter a pre-qualifying session, with the fastest cars allowed through to the main qualifying session. The qualifying format began to change in the early 2000s, with the FIA experimenting with limiting the number of laps, determining the aggregate time over two sessions, and allowing each driver only one qualifying lap. The current qualifying system
8798-662: The races must be held on grade one tracks , the highest grade rating the FIA issues for tracks. Formula One cars are the world's fastest regulated road-course racing cars , owing to very high cornering speeds achieved by generating large amounts of aerodynamic downforce , much of which is generated by front and rear wings. The cars depend on electronics, aerodynamics , suspension , and tyres . Traction control , launch control , and automatic shifting , and other electronic driving aids were first banned in 1994 . They were briefly reintroduced in 2001 , and have more recently been banned since 2004 and 2008 , respectively. With
8904-420: The radiators from the front wing assembly leaving a clean aerodynamic wing and moving the centre of gravity further back again. The standard radiators were replaced by units from a Volkswagen Golf mounted behind the front wheels out of the airstream in a region of positive pressure. The BT46C only ran in practice for the 1978 Austrian Grand Prix . The drivers complained of reduced revs and straight-line speed. It
9010-418: The second engine before being banned by the sporting authorities. The contemporary Tyrrell 008 designed by Maurice Philippe had been built with a small fan fitted at the rear and driven from the engine's crankshaft. Ostensibly to act as an extractor fan for the radiators, which were mounted underneath the car, the fan had the side effect of its operation providing a modicum of downforce. However, in testing,
9116-459: The session. The race begins with a warm-up lap, after which the cars assemble on the starting grid in the order they qualified. This lap is often referred to as the formation lap, as the cars lap in formation with no overtaking (although a driver who makes a mistake may regain lost ground). The warm-up lap allows drivers to check the condition of the track and their car, gives the tyres a chance to warm up to increase traction and grip, and also gives
9222-406: The sole tyre supplier to Formula One for the 2007 season by default. On 20 December 2007 Bridgestone signed a contract that officially made it the exclusive tyre supplier for the next three seasons. During 2006, Max Mosley outlined a 'green' future for Formula One, in which efficient use of energy would be an important factor. Starting in 2000, with Ford's purchase of Stewart Grand Prix to form
9328-487: The sport . Team Gunston became the first team to run cigarette sponsorship on its Brabham cars, which privately entered in orange, brown and gold colours of Gunston cigarettes in the 1968 South African Grand Prix on 1 January 1968. Five months later, the first works team , Lotus, initially using the British racing green , followed this example when it entered its cars painted in the red, gold, and white colours of
9434-663: The sport. After Honda's return as an engine manufacturer in 2015, Renault came back as a team in 2016 after buying back the Lotus F1 team. In 2018, Aston Martin and Alfa Romeo became Red Bull and Sauber's title sponsors, respectively. Sauber was rebranded as Alfa Romeo Racing for the 2019 season, while Racing Point part-owner Lawrence Stroll bought a stake in Aston Martin to rebrand the Racing Point team as Aston Martin for 2021. In August 2020, all ten F1 teams signed
9540-408: The system was found to not be particularly effective. The car overheated, partly as a result of the size of the fan which was limited by the amount of space available. The fan concept was abandoned in favour of conventionally mounted radiators. Nevertheless, Cox, who was present at the tests and saw potential in the idea if properly developed, informed Murray of what Tyrrell had attempted. Cox produced
9646-536: The team winning 16 out of the 19 races that season. The team continued this form in the next two seasons, again winning 16 races in 2015 before taking a record 19 wins in 2016 , with Hamilton claiming the title in the former year and Rosberg winning it in the latter by five points. The 2016 season also saw a new team, Haas , join the grid, while Max Verstappen became the youngest-ever race winner at age 18 in Spain . After revised aerodynamic regulations were introduced,
9752-507: The teams reached an agreement to prevent a breakaway series. It was agreed teams must cut spending to the level of the early 1990s within two years; exact figures were not specified, and Max Mosley agreed he would not stand for reelection to the FIA presidency in October. Following further disagreements, after Mosley suggested he would stand for reelection, FOTA made it clear that breakaway plans were still being pursued. On 8 July, FOTA issued
9858-600: The teams to "hunt as a pack" through FOCA. He offered Formula One to circuit owners as a package they could take or leave. In return for the package, almost all that was required was to surrender trackside advertising. The formation of the Fédération Internationale du Sport Automobile (FISA) in 1979 set off the FISA–FOCA war , during which FISA and its president Jean-Marie Balestre argued repeatedly with FOCA over television revenues and technical regulations. The Guardian said that Ecclestone and Max Mosley "used [FOCA] to wage
9964-672: The technological advances of the 1990s, the cost of competing in Formula One increased dramatically, thus increasing financial burdens. This, combined with the dominance of four teams (largely funded by big car manufacturers such as Mercedes-Benz), caused the poorer independent teams to struggle not only to remain competitive but to stay in business. This effectively forced several teams to withdraw. Michael Schumacher and Ferrari won five consecutive Drivers' Championships (2000–2004) and six consecutive Constructors' Championships (1999–2004). Schumacher set many new records, including those for Grand Prix wins (91, since beaten by Lewis Hamilton ), wins in
10070-460: The throttle, the car could be seen to squat down on its suspension as the downforce increased. Lotus driver Mario Andretti said: "It is like a bloody great vacuum cleaner. It throws muck and rubbish at you at a hell of a rate." Murray says that this was untrue, arguing: "The fan couldn't spit anything out the back because the fan efflux [exit speed] was only 55 mph. Besides the radial fan would have sent any stones flying sideways." The legality of
10176-478: The track as well. Drivers from McLaren , Williams , Renault (formerly Benetton ), and Ferrari , dubbed the "Big Four", won every World Championship from 1984 to 2008 . The teams won every Constructors' Championship from 1979 to 2008 , as well as placing themselves as the top four teams in the Constructors' Championship in every season between 1989 and 1997 , and winning every race but one (the 1996 Monaco Grand Prix ) between 1988 and 1997 . Due to
10282-425: The wake behind the car turbulent or 'dirty'. This prevented other cars from following closely due to their dependence on 'clean' air to make the car stick to the track. The grooved tyres also had the unfortunate side effect of initially being of a harder compound to be able to hold the grooved tread blocks, which resulted in spectacular accidents in times of aerodynamic grip failure, as the harder compound could not grip
10388-416: The wheel of such a car, and the physical effort needed to drive the cars would leave the drivers exhausted by the end of the races. The two modified cars were prepared for the Swedish Grand Prix at Anderstorp on 17 June 1978, for Niki Lauda and John Watson. When not in use, the fan was covered by a dustbin lid, but it soon became clear what the modified Brabham was intended to achieve: when the drivers blipped
10494-532: Was added in the 1958 season . Stirling Moss , despite being regarded as one of the greatest Formula One drivers in the 1950s and 1960s, never won the Formula One championship. Between 1955 and 1961, Moss finished second in the championship four times and third the other three times. Fangio won 24 of the 52 races he entered—still the record for the highest Formula One winning percentage by an individual driver. National championships existed in South Africa and
10600-525: Was adopted in the 2006 season. Known as "knock-out" qualifying, it is split into three periods, known as Q1, Q2, and Q3. In each period, drivers run qualifying laps to attempt to advance to the next period, with the slowest drivers being "knocked out" of qualification (but not necessarily the race) at the end of the period and their grid positions set within the rearmost five based on their best lap times. Drivers are allowed as many laps as they wish within each period. After each period, all times are reset, and only
10706-402: Was an overweight and bulky car, initially weighing 625 kg and as wide as was permitted under the F1 technical regulations. This was due to the difficulties of packaging the large, powerful Alfa flat-12 engine and the fuel it required to complete a race distance. After lengthy development, it became competitive, but never won a race. In mid-1977, Brabham designer Gordon Murray started work on
10812-545: Was driven to victory by Ayrton Senna in the Monaco Grand Prix that year. In the early 1990s, other teams followed suit and semi-automatic gearboxes and traction control were a natural progression. The FIA, due to complaints that technology was determining races' outcomes more than driver skill, banned many such aids for the 1994 season. This resulted in cars that previously depended on electronic aids becoming very "twitchy" and difficult to drive. Observers felt
10918-466: Was invited by the team to discuss his calculations, pointed out what he believed to be fundamental errors in the concept and concluded that the idea could not be made to work. The heat exchangers were replaced by more standard radiators in the nose of the car, similar to that of the BT45, compromising its aerodynamic efficiency. In addition to the question of drag the nose-mounted radiators moved weight towards
11024-483: Was not compromised by a decrease in straight line speed. In 1978 Lotus ironed out the reliability problems and further developed the concept from relatively simple sidepods with a wing profile into full venturi tunnels under the car. As soon as they appeared at Zolder , the black and gold Type 79s of Mario Andretti and Ronnie Peterson outpaced the opposition by a comfortable margin. It had not been clear to other designers just what Wright and Chapman had done with
11130-552: Was not used in the race and did not appear again. ( key ) (results in bold indicate pole position; results in italics indicate fastest lap) ^1 This total includes points scored by the BT45C car Brabham used during the first two races. ^2 This total includes points scored by the BT48 & BT49 cars Brabham used for the rest of the season. Formula One Formula One , commonly known as Formula 1 or F1 ,
11236-564: Was to use another way of reducing the pressure underneath the car. In 1970 the Chaparral 2J "sucker car" had proved significantly faster than its opposition in the North American Can-Am sportscar series. The 2J had two fans at the rear of the car driven by a dedicated two-stroke engine to draw large amounts of air from under the chassis, reducing pressure and creating downforce. It had suffered from reliability problems with
