All about F1

Formula One, abbreviated to F1, is the highest class of open wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. The "formula" in the name refers to a set of rules to which all participants and cars must conform. The F1 world championship season consists of a series of races, known as Grands Prix, held usually on purpose-built circuits, and in a few cases on closed city streets, the most famous of which is the Monaco Grand Prix in Monte Carlo. The results of each race are combined to determine two annual World Championships, one for drivers and one for constructors.
Formula One cars race at high speeds, up to 360 km/h (225 mph) with the engine revving up to 19000 RPM. The cars are capable of pulling 5g's in some corners. The performance of the cars is highly dependent on electronics, aerodynamics, suspension and tyres. The engine and transmission of a modern Formula One car are some of the most highly stressed pieces of machinery on the planet. The formula has seen many evolutions and changes through the history of the sport.

Europe is Formula One's traditional centre; all of the teams are based there and around half the races take place there. In particular the United Kingdom has produced the most Drivers' Champions, and the vast majority of Constructors' Champions . However, the sport's scope has expanded significantly in recent years and Grands Prix are now held all over the world. Events in Europe and the Americas have been dropped in favour of races in Bahrain, China, Malaysia and Turkey, with Singapore having held the first night race in 2008 and India being added to the schedule starting in 2011. Of the eighteen races in 2008, nine are outside Europe.
The Formula One series has its roots in the European Grand Prix Motor Racing (q.v. for pre-1947 history) of the 1920s and 1930s. The "formula" is a set of rules which all participants and cars must meet. Formula One was a new formula agreed after World War II in 1946, with the first non-championship races being held that year. A number of Grand Prix racing organisations had laid out rules for a World Championship before the war, but due to the suspension of racing during the conflict, the World Drivers' Championship was not formalised until 1947. The first world championship race was held at Silverstone, United Kingdom in 1950. A championship for constructors followed in 1958. National championships existed in South Africa and the UK in the 1960s and 1970s. Non-championship Formula One races were held for many years but, due to the rising cost of competition, the last of these occurred in 1983.

Since 1984 Formula One teams have been required to build the chassis in which they compete, and consequently the terms "team" and "constructor" became more or less interchangeable. This requirement distinguishes the sport from series such as the IndyCar Series which allows teams to purchase chassis, and "spec series" such as GP2, which require all cars be kept to an identical specification.

The sport's 1950 debut season saw eighteen teams compete, but due to high costs many dropped out quickly. In fact, such was the scarcity of competitive cars for much of the first decade of Formula One that Formula Two cars were admitted to fill the grids. Ferrari is the only still-active team which competed in 1950.

Early manufacturer involvement came in the form of a "factory team" or "works team" (that is, one owned and staffed by a major car company), such as those of Alfa Romeo, Ferrari or Renault. After having virtually disappeared by the early 1980s, factory teams made a comeback in the 1990s and 2000s and now form half the grid with Ferrari, BMW, Renault, Toyota and Honda either setting up their own teams or buying out existing ones. Mercedes-Benz owns 40% of the McLaren team and manufactures the team's engines. Factory teams currently make up the top competitive teams; in mid-2008 factory teams occupied the top 5 positions in the Constructors' Championship. Ferrari holds the record for having won the most Constructors' Championships.

Companies such as Climax, Repco, Cosworth, Hart, Judd and Supertec, which had no direct team affiliation, often sold engines to teams that could not afford to manufacture them. In the early years independently owned Formula One teams sometimes also built their engines, though this became less common with the increased involvement of major car manufacturers such as BMW, Ferrari, Honda, Mercedes-Benz, Renault and Toyota, whose large budgets rendered privately built engines less competitive. Cosworth was the last independent engine supplier, but lost its last customers after the 2006 season. Beginning in 2007 the manufacturers' deep pockets and engineering ability took over, eliminating the last of the independent engine manufacturers. It is estimated that the big teams spend €100 to €200 million ($125-$250 million) per year per manufacturer on engines alone.

In the 2007 season, for the first time since the 1984 rule, two teams used chassis built by other teams. Super Aguri started the season using a modified Honda Racing's RA106 chassis (used by Honda in the 2006 season), while Scuderia Toro Rosso used a modified Red Bull Racing RB3 chassis (same as the one used by Red Bull in the 2007 season). Such a decision did not come as a surprise because of spiraling costs and the fact that Super Aguri is partially owned by Honda and Toro Rosso is half owned by Red Bull. Formula One team Spyker raised a complaint against this decision, and other teams such as McLaren and Ferrari have officially confirmed that they support the campaign. Because of this use of other teams' chassis, the 2006 season could have been the last one in which the terms "team" and "constructor" were truly interchangeable. This attracted the Prodrive team to F1 to the 2008 season, where it intended to run a customer car. After not being able to secure a package from McLaren, Prodrive's intention to enter the 2008 season was dropped after Williams threatened legal action against them. Now, it seems that customer cars concept will be formally banned in 2010.

As of mid 2008, ten teams are on the grid, each fielding two cars.
Although teams rarely disclose information about their budgets, it is estimated that they range from US$66 million to US$400 million each.

Entering a new team in the Formula One World Championship requires a £25 million (about US$47 million) up-front payment to the FIA, which is then repaid to the team over the course of the season. As a consequence, constructors desiring to enter Formula One often prefer to buy an existing team: B.A.R.'s purchase of Tyrrell and Midland's purchase of Jordan allowed both of these teams to sidestep the large deposit and secure the benefits that the team already had, such as TV revenue.

Modern Formula One cars are mid-engined open cockpit, open wheel single-seaters. The chassis is made largely of carbon fibre composites, rendering it light but extremely stiff and strong. The whole car, including engine, fluids and driver, weighs only 600kg - the minimum weight set by the regulations. The construction of the cars is typically lighter than the minimum and so they are ballasted up to the minimum weight. The race teams take advantage of this by placing this ballast at the extreme bottom of the chassis, thereby locating the centre of gravity as low as possible in order to improve handling and weight transfer.

The cornering speed of Formula One cars is largely determined by the aerodynamic downforce that they generate, which pushes the car down onto the track. This is provided by 'wings' mounted at the front and rear of the vehicle, and by ground effect created by low pressure air under the flat bottom of the car. The aerodynamic design of the cars is very heavily constrained to limit performance and the current generation of cars sport a large number of small winglets, 'barge boards' and turning vanes designed to closely control the flow of the air over, under and around the car.

The other major factor controlling the cornering speed of the cars is the design of the tyres. Since 1998, tyres in Formula One have not been 'slicks' (tyres with no tread pattern) as in most other circuit racing series. Instead, each tyre has four large circumferential grooves on its surface designed to limit the cornering speed of the cars.Slick tyres will return to Formula One in the 2009 season. Suspension is double wishbone or multilink all round with pushrod operated springs and dampers on the chassis. Carbon-Carbon disc brakes are used for reduced weight and increased frictional performance. These provide a very high level of braking performance and are usually the element which provokes the greatest reaction from drivers new to the formula.
Engines must be 2.4 litre naturally aspirated V8s, with many other constraints on their design and the materials that may be used. Engines run on unleaded fuel closely resembling publicly available petrol.The oil which lubricates and protects the engine from overheating is very similar in viscosity to water. The 2006 generation of engines spun up to 20,000 rpm and produced up to 780 bhp (582 kW). For 2007 engines are restricted to 19,000 rpm with limited development areas allowed, following the engine specification freeze from the end of 2006.
A wide variety of technologies – including active suspension, ground effect and turbochargers – are banned under the current regulations. Despite this the current generation of cars can reach speeds of up to 350 km/h (around 220 mph) at some circuits.A Honda Formula One car, running with minimum downforce on a runway in the Mojave desert achieved a top speed of 415 km/h (258 mph) in 2006. According to Honda the car fully met the FIA Formula One regulations.Even with the limitations on aerodynamics, at 160 km/h aerodynamically generated downforce is equal to the weight of the car and the often repeated claim that Formula One cars create enough downforce to 'drive on the ceiling' remains true in principle, although it has never been put to the test. At full speed, downforce of two and a half times the car's weight can be achieved. The downforce means that the cars can achieve a lateral force of up to five times the force of gravity (5g) in cornering – a high-performance road car like the Ferrari Enzo only achieves around 1g.Consequently in corners the driver's head is pulled sideways with a force equivalent to 20kg. Such high lateral forces are enough to make breathing difficult and the drivers need supreme concentration and fitness to maintain their focus for the one to two hours that it takes to complete the race.

Currently the terms "Formula One race" and "World Championship race" are effectively synonymous; since 1984, every Formula One race has counted towards the World Championship, and every World Championship race has been to Formula One regulations. But the two terms are not interchangeable. Consider that:

the first Formula One race was held in 1947, whereas the World Championship did not start until 1950. in the 1950s and 1960s there were many Formula One races which did not count for the World Championship (e.g., in 1950, a total of twenty-two Formula One races were held, of which only six counted towards the World Championship). The number of non-championship Formula One events decreased throughout the 1970s and 1980s, to the point where the last non-championship Formula One race was held in 1983. the World Championship was not always exclusively composed of Formula One events: The World Championship was originally established as the "World Championship for Drivers", i.e., without the term "Formula One" in the title. It only officially became the Formula One World Championship in 1981. From 1950 to 1960, the Indianapolis 500 counted towards the World Championship. This race was run to AAA/USAC regulations, rather than to Formula One regulations. From 1952 to 1953, all races counting towards the World Championship (except the Indianapolis 500) were run to Formula Two regulations. Note that Formula One was not "changed to Formula Two" during this period; the Formula One regulations remained the same, and numerous Formula One races were staged during this time. The distinction is most relevant when considering career summaries and "all time lists". For example, in the List of Formula One drivers, Clemente Biondetti is shown with 1 race against his name. Biondetti actually competed in four Formula One races in 1950, but only one of these counted for the World Championship. Similarly, several Indy 500 winners technically won their first world championship race, though most record books choose to ignore this and instead only record regular participants.
