Auto racing
from Wikipedia

Auto racing (also known as car racing, motor racing,[1] or automobile racing) is a motorsport involving the racing of automobiles for competition. In North America, the term is commonly used to describe all forms of automobile sport including non-racing disciplines.

Key Information

Auto racing has existed since the invention of the automobile. Races of various types were organized, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed.

There are now numerous different categories, each with different rules and regulations.

History

[edit]

The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, England, a distance of 8 mi (13 km). It was won by the carriage of Isaac Watt Boulton.[2]

Internal combustion auto racing events began soon after the construction of the first successful gasoline-fueled automobiles. The first organized contest was on April 28, 1887, by the chief editor of Paris publication Le Vélocipède, Monsieur Fossier.[3] It ran 2 kilometres (1.2 mi) from Neuilly Bridge to the Bois de Boulogne.

On July 22,[4] 1894, the Parisian magazine Le Petit Journal organized what is considered to be the world's first motoring competition, from Paris to Rouen. One hundred and two competitors paid a 10-franc entrance fee.[3]

The first American automobile race is generally considered to be the Thanksgiving Day Chicago Times-Herald race of November 28, 1895.[5] Press coverage of the event first aroused significant American interest in the automobile.[5]

The Targa Florio was an open road endurance automobile race held in the mountains of Sicily, Italy near the island's capital of Palermo. Founded in 1906, it was the oldest sports car racing event, part of the World Sportscar Championship between 1955 and 1973, and it was discontinued in 1977.

The oldest surviving sports car racing event is the 24 Hours of Le Mans, begun in 1923. It is run by the Automobile Club of the West (ACO). Team Ferrari won the race in 2023.

With auto construction and racing dominated by France, the French automobile club ACF staged a number of major international races, usually from or to Paris, connecting with another major city, in France or elsewhere in Europe.

Aspendale Racecourse, in Australia, was the world's first purpose-built motor racing circuit, opening in January 1906. The pear-shaped track was close to a mile in length, with slightly banked curves and a gravel surface of crushed cement.

Brooklands, in Surrey, England, was the first purpose-built 'banked' motor racing venue, opening in June 1907.[6] It featured a 4.43 km (2.75 mi) concrete track with high-speed banked corners.

One of the oldest existing purpose-built and still in use automobile race course in the United States is the 2.5-mile-long (4.0 km) Indianapolis Motor Speedway in Speedway, Indiana. It is the largest capacity sports venue of any variety worldwide, with a top capacity of some 257,000+ seated spectators.[7]

NASCAR was founded by Bill France Sr. on February 21, 1948, with the help of several other drivers. The first NASCAR "Strictly Stock" race ever was held on June 19, 1949, at Daytona Beach, Florida, U.S..

From 1962, sports cars temporarily took a back seat to GT cars, with the Fédération Internationale de l'Automobile (FIA) replacing the World Championship for Sports Cars with the International Championship for GT Manufacturers.[8]

From 1962 through 2003, NASCAR's premier series was called the Winston Cup Series, sponsored by R. J. Reynolds Tobacco Company cigarette brand Winston. The changes that resulted from RJR's involvement, as well as the reduction of the schedule from 56 to 34 races a year, established 1972 as the beginning of NASCAR's "modern era".

The IMSA GT Series evolved into the American Le Mans Series, which ran its first season in 1998.[9] The European races eventually became the closely related European Le Mans Series, both of which mix prototypes and GTs.

Turismo Carretera (TC) is a popular touring car racing series in Argentina, and one of the oldest car racing series still active in the world. The first TC competition took place in 1931 with 12 races, each in a different province. Future Formula One star Juan Manuel Fangio (Chevrolet) won the 1940 and 1941 editions of the TC. It was during this time that the series' Chevrolet-Ford rivalry began, with Ford acquiring most of its historical victories.

Over the last few years, auto racing has seen a transformative shift, echoing past pivots.[citation needed] The industry, much like the cars it champions, has had to navigate through a global pandemic and a persistent chip shortage,[10][11] each threatening to derail production schedules.[12] At the same time, a new course is being charted towards an electric future, a dramatic change in direction that is challenging the old guard of gasoline engines. There is also a growing number of events for electric racing cars, such as the Formula E, the Eco Grand Prix or the Electric GT Championship.[13][citation needed]

Racing driver's view

In single-seater (open-wheel) racing, the wheels are not covered, and the cars often have aerofoil wings front and rear to produce downforce and enhance adhesion to the track. The most popular varieties of open-wheel road racing are Formula One, IndyCar Series and Super Formula. In Europe and Asia, open-wheeled racing is commonly referred to as 'Formula', with appropriate hierarchical suffixes. In North America, the 'Formula' terminology is not followed (with the exception of Formula One). The sport is usually arranged to follow an international format (such as Formula One), a regional format (such as the Formula 3 Euro Series), and/or a domestic, or country-specific, format (such as the German Formula 3 championship, or the British Formula Ford).

Formula One is a worldwide series that runs only street circuit and race tracks. These cars are heavily based on technology and their aerodynamics. The speed record was set in 2005 by Juan Pablo Montoya hitting 373 km/h (232 mph).[14] Some of the most prominent races are the Monaco Grand Prix, the Italian Grand Prix, and the British Grand Prix. The season ends with the crowning of the World Championship for drivers and constructors.

In the United States, the most popular series is the IndyCar Series. The cars have traditionally been similar to, though less technologically sophisticated than, F1 cars, with more restrictions on technology aimed at controlling costs. While these cars are not as technologically advanced, they are faster, in part due to their lower downforce compared to Formula One cars, and also because they compete on oval race tracks, being able to average a lap at 388 km/h (241 mph). The series' biggest race is the Indianapolis 500, which is commonly referred to as "The Greatest Spectacle in Racing" due to being the longest continuously run race in the series and having the largest crowd for a single-day sporting event (350,000+).

The other major international single-seater racing series is Formula 2 (formerly known as Formula 3000 and GP2 Series). Regional series include Super Formula and Formula V6 Asia (specifically in Asia), Formula Renault 3.5 (also known as the World Series by Renault, succession series of World Series by Nissan), Formula Three, Formula Palmer Audi and Formula Atlantic. In 2009, the FIA Formula Two Championship brought about the revival of the F2 series. Domestic, or country-specific, series include Formula Three and Formula Renault, with the leading introductory series being Formula Ford.[15]

Single-seater racing is not limited merely to professional teams and drivers. There exist many amateur racing clubs. In the UK, the major club series are the Monoposto Racing Club, BRSCC F3 (formerly ClubF3, formerly ARP F3), Formula Vee, Club Formula Ford and Formula 4. Each series caters to a section of the market, with some primarily providing low-cost racing, while others aim for an authentic experience using the same regulations as the professional series (BRSCC F3). The SCCA is also responsible for sanctioning single-seater racing in much of North America.

There are other categories of single-seater racing, including kart racing, which employs a small, low-cost machine on small tracks. Many of the current top drivers began their careers in karts. Formula Ford represents the most popular first open-wheel category for up-and-coming drivers stepping up from karts. The series is still the preferred option, as it has introduced an aero package and slicks, allowing the junior drivers to gain experience in a race car with dynamics closer to Formula One. The Star Mazda Series is another entry-level series. Indy Lights represent the last step on the Road to Indy, being less powerful and lighter than an IndyCar racer.

Students at colleges and universities can also take part in single-seater racing through the Formula SAE competition, which involves designing and building a single-seater car in a multidisciplinary team and racing it at the competition. This also develops other soft skills, such as teamwork, while promoting motorsport and engineering.

The world's first all-female Formula racing team was created in 2006. The group was an assemblage of drivers from different racing disciplines and formed for an MTV reality pilot, which was shot at Mazda Raceway Laguna Seca.

In December 2005, the FIA gave approval to Superleague Formula racing, which debuted in 2008, whereby the racing teams are owned and run by prominent sports clubs such as A.C. Milan and Liverpool F.C.

After 25 years away from the sport, former Formula 2 champion Jonathan Palmer reopened the F2 category again; most drivers have graduated from the Formula Palmer Audi series. The category is officially registered as the FIA Formula Two championship. Most rounds have two races and are support races to the FIA World Touring Car Championship.

Touring car racing

[edit]

Touring car racing is a style of road racing that is run with production-derived four-seat race cars. The lesser use of aerodynamics means following cars have a much easier time following and passing than in open-wheel racing. It often features full-contact racing with subtle bumping and nudging due to the small speed differentials and large grids.

The major touring car championships conducted worldwide are the Supercars Championship (Australia), British Touring Car Championship, Deutsche Tourenwagen Masters (DTM), World Touring Car Championship and the World Touring Car Cup. The European Touring Car Cup is a one-day event open to Super 2000 specification touring cars from Europe's many national championships. While Super GT traces its lineage to the now-defunct JGTC, the cars are much more similar to GT3 race cars than proper touring cars, and also have much more aggressive aerodynamics.

The Sports Car Club of America's SPEED World Challenge Touring Car and GT championships are dominant in North America. America's historic Trans-Am Series is undergoing a period of transition, but is still the longest-running road racing series in the U.S. The National Auto Sport Association also provides a venue for amateurs to compete in home-built factory-derived vehicles on various local circuits.

Sports car racing

[edit]

In sports car racing, production-derived versions of two-seat sports cars, also known as grand tourers (GTs), and purpose-built sports prototype cars compete within their respective classes on closed circuits. The premier championship series of sports car racing is the FIA World Endurance Championship. The main series for GT car racing is the GT World Challenge Europe, divided into two separate championships: the GT World Challenge Europe Sprint Cup and the GT World Challenge Europe Endurance Cup. This series has formed after the folding of the various FIA GT championships.

The prevailing classes of GT cars are GT3, GT4 and GT2 class cars. GT2 cars have powerful engines, often exceeding 600 horsepower. However, they have less downforce than GT3 cars and also have less driver aids. GT3 cars are far and away the most popular class of GT cars, with premier racing series such as the FIA World Endurance Championship and IMSA both using GT3 as their top class of GT car. GT3 cars have more significant aero than a GT2 car, but also have less horsepower, typically falling in between 500 and 550 horsepower. GT4 class cars have very little aerodynamics and less horsepower than GT3 machinery, typically around 450 horsepower. GT4 typically serves as the last step up to premier GT-class racing.

Other major GT championships include the GT World Challenge America, GT World Challenge Asia, Super GT, and the International GT Open. There are minor regional and national GT series using mainly GT4 and GT3 cars featuring both amateur and professional drivers.

Sports prototypes, unlike GT cars, do not rely on road-legal cars as a base. They are closed-wheel and often closed-cockpit purpose-built race cars intended mainly for endurance racing. They have much lower weight, more horsepower and more downforce compared to GT cars, making them much faster. They are raced in the 24 hours of Le Mans (held annually since 1923) and in the (European) Le Mans series, Asian Le Mans Series and the WeatherTech SportsCar Championship. These cars are referred to as LMP (Le Mans prototype) cars with LMH and LMDh cars being run mainly by manufacturers and the slightly less powerful LMP2 cars run by privateer teams. All three Le Mans Series run GT cars in addition to Le Mans Prototypes; these cars have different restrictions than the FIA GT cars.

Another prototype and GT racing championship exists in the United States; the Grand-Am, which began in 2000, sanctions its own endurance series, the Rolex Sports Car Series, which consists of slower and lower-cost Daytona Prototype race cars compared to LMP and FIA GT cars. The Rolex Sports Car Series and American Le Mans Series announced a merger between the two series forming the WeatherTech SportsCar Championship starting in 2014.

These races are often conducted over long distances, at least 1,000 km (621 mi), and cars are driven by teams of two or more drivers, switching every few hours. Due to the performance difference between production-based sports cars and purpose-built sports prototypes, one race usually involves several racing classes, each fighting for its own championship.

Famous sports car races include the 24 Hours of Le Mans, the Rolex 24 at Daytona, 24 Hours of Spa-Franchorchamps, the 12 Hours of Sebring, the 6 Hours of Watkins Glen, and the 1,000-mile (1,600 km) Petit Le Mans at Road Atlanta. There is also the 24 Hours of the Nürburgring on the famed Nordschleife track and the Dubai 24 Hour, which is aimed at GT3 and below cars with a mixture of professional and pro-am drivers.

Production-car racing

[edit]

Production-car racing, otherwise known as "showroom stock" in the US, is an economical and rules-restricted version of touring-car racing, mainly used to restrict costs. Numerous production racing categories are based on particular makes of cars.

Most series, with a few exceptions, follow the Group N regulation. There are several different series that are run all over the world, most notably, Japan's Super Taikyu and IMSA's Firehawk Series, which ran in the 1980s and 1990s all over the United States.

Stock car racing

In North America, stock car racing is the most popular form of auto racing.[16] Primarily raced on oval tracks, stock cars vaguely resemble production cars, but are in fact purpose-built racing machines that are built to tight specifications and, together with touring cars, also called Silhouette racing cars.

The largest stock car racing governing body is NASCAR (National Association for Stock Car Auto Racing). NASCAR's premier series is the NASCAR Cup Series, its most famous races being the Daytona 500, the Southern 500, the Coca-Cola 600, and the Brickyard 400. NASCAR also runs several feeder series, including the Xfinity Series and Craftsman Truck Series (a pickup truck racing series). The series conduct races across the entire continental United States. NASCAR also sanctions series outside of the United States, including the NASCAR Canada Series, NASCAR Mexico Series, NASCAR Whelen Euro Series, and NASCAR Brasil Sprint Race.

NASCAR also governs several smaller regional series, such as the Whelen Modified Tour. Modified cars are best described as open-wheel cars. Modified cars have no parts related to the stock vehicle for which they are named after. A number of modified cars display a "manufacturer's" logo and "vehicle name", yet use components produced by another automobile manufacturer.

There are also other stock car governing bodies, most notably the Automobile Racing Club of America (ARCA).

In the UK, British Stock car racing is also referred to as "Short Circuit Racing". UK Stock car racing started in the 1950s and grew rapidly through the 1960s and 1970s. Events take place on shale or tarmac tracks – usually around 1/4 mile long. There are around 35 tracks in the UK and upwards of 7000 active drivers. The sport is split into three basic divisions – distinguished by the rules regarding car contact during racing. The most famous championship are the BriSCA F1 Stock Cars.

Full-contact formulas include Bangers, Bombers, and Rookie Bangers – and racing features Demolition Derbies, Figure of Eight, and Oval Racing.

Semi Contact Formulas include BriSCA F1, F2, and Superstox – where bumpers are used tactically.

Non-contact formulas include National Hot Rods, Stock Rods, and Lightning Rods.

One-make racing

[edit]

One-make, or single marque, championships often employ production-based cars from a single manufacturer or even a single model from a manufacturer's range. There are numerous notable one-make formulae from various countries and regions, some of which – such as the Porsche Supercup and, previously, IROC – have fostered many distinct national championships. Single marque series are often found at the club level, to which the production-based cars, limited modifications, and close parity in performance are very well suited. Some of the better-known single-make series are the Mini 7 Championship (Europe's longest-running one-make championship), the Radical European Masters, John Cooper Mini Challenge, Clio Cup, Ginettas, Caterhams, BMWs, and MX5s. There are also single-chassis single seater formulae, such as Formula Renault and Formula BMW, usually as "feeder" series for "senior" race formula (in the fashion of farm teams).

Drag racing

[edit]

In drag racing, the objective is to complete a given straight-line distance, from a standing start, ahead of a vehicle in a parallel lane. This distance is traditionally 14 mile (400 m), though 1,000 feet (300 m) and 18 mile (200 m) are also common. The vehicles may or may not be given the signal to start at the same time, depending on the class of racing. Vehicles range from the everyday car to the purpose-built dragster. Speeds and elapsed time differ from class to class. Average street cars cover the 14 mile in 12 to 16 seconds, whereas a top fuel dragster takes 4.5 seconds or less, reaching speeds of up to 530 km/h (329 mph). Drag racing was organized as a sport by Wally Parks in the early 1950s through the National Hot Rod Association (NHRA). The NHRA was formed to discourage street racing.

When launching, a top fuel dragster will accelerate at 3.4 g (33 m/s2), and when braking parachutes are deployed the deceleration is 4 g (39 m/s2), more than the Space Shuttle experiences. A top fuel car can be heard over 8 miles (13 km) away and can generate a reading equivalent to a magnitude 1.5 to 3.9 earthquake.[17]

Drag racing is two cars head-to-head, the winner proceeding to the next round. Professional classes are all first to the finish line wins. Sportsman racing is handicapped (slower car getting a head start) using an index (a lowest e.t. allowed), and cars running under (quicker than) their index "break out" and lose. The slowest cars, bracket racers, are also handicapped, but rather than an index, they use a dial-in.

Off-road racing

[edit]

In off-road racing, various classes of specially modified vehicles, including cars, compete in races through off-road environments. In North America these races often take place in the desert, such as the famous Baja 1000. Another format for off-road racing happens on closed-course short course tracks such as Crandon International Off-Road Raceway. In the 1980s and 1990s, the short course was extended to racing inside stadiums in the Mickey Thompson Entertainment Group; this format was revived by Robby Gordon in 2013 with his Stadium Super Trucks series.

In Europe, "offroad" refers to events such as autocross or rallycross, while desert races and rally-raids such as the Paris-Dakar, Master Rallye or European "bajas" are called "cross-country rallies".

Kart racing

[edit]

The modern kart was invented by Art Ingels, a fabricator at the Indianapolis-car manufacturer Kurtis-Kraft, in Southern California in 1956. Ingels took a small chainsaw engine and mounted it to a simple tube-frame chassis weighing less than 100 lb. Ingels, and everyone else who drove the kart, were startled at its performance capabilities. The sport soon blossomed in Southern California, and quickly spread around the world. Although often seen as the entry point for serious racers into the sport, kart racing, or karting, can be an economical way for amateurs to try racing and is also a fully-fledged international sport in its own right. A large proportion of professional racing drivers began in karts, often from a very young age, such as Michael Schumacher and Fernando Alonso. Several former motorcycle champions have also taken up the sport, notably Wayne Rainey, who was paralysed in a racing accident and now races a hand-controlled kart. As one of the cheapest ways to race, karting is seeing its popularity grow worldwide.

Despite their diminutive size, karts of the most powerful class, superkart (assuming a weight of 205 kg (452 lb), and a power output of 100 hp (75 kW)), can have a power-to-weight ratio (including the driver) of 490 hp/tonne (0.22 hp/lb). Without the driver, this figure doubles, to almost 980 hp/tonne (0.44 hp/lb).

Historical racing

[edit]

Historic motorsport or vintage motorsport uses vehicles limited to a particular era. Only safety precautions are modernized in these hobbyist races. A historical event can be of various types of motorsport disciplines, from road racing to rallying. Because it is based on a particular era it is more hobbyist-oriented, reducing corporate sponsorship. The only modern equipment used is related to safety and timing. A historical event can be of a number of different motorsport disciplines.

Some of the most famous events include the Goodwood Festival of Speed and Goodwood Revival in Britain and Monterey Historic in the United States. Championships range from "grass root" Austin Seven racing to the FIA Thoroughbred Grand Prix Championship for classic Formula One chassis. While there are several professional teams and drivers in historical racing, this branch of auto sport tends to be contested by wealthy car owners and is thus more amateur and less competitive in its approach.

Other categories

[edit]

Scoring

[edit]

Each motor racing series has a points system, and a set of rules and regulations that define how points are accrued. Nearly all series award points according to the finishing position of the competitors in each race. Some series only award points for a certain number of finishing positions. In Formula One, for example, only the top ten finishers get points. Drivers may be forced to finish the race or complete a certain number of the laps in order to score points.

In some series, points are also awarded based on lap leading, lap times, overtaking and qualifying positions (in particular by achieving pole positions and fastest laps). In NASCAR, for example, besides receiving points depending on the final standings, one point is awarded for leading a lap and one point for leading the most laps in the race. In other series, such as for the National Hot Rod Association, points are awarded for attempting the race along with a podium finish in any of the four qualifying rounds, as an incentive to have drivers participate week after week to compete.

Use of flags

[edit]

In many types of auto races, particularly those held on closed courses, flags are displayed to indicate the general status of the track and to communicate instructions to competitors. While individual series have different rules, and the flags have changed from the first years (e.g., red used to start a race), these are generally accepted.

Flag Displayed from the start tower Displayed from the observation post
Green flag The session has started or resumed after a full course caution or stop. End of the hazardous section of the track.
Yellow flag Full course caution condition for ovals. On road courses, it means a local area of caution. Depending on the type of racing, either two yellow flags will be used for a full course caution or a sign with 'SC' (Safety car) will be used as the field follows the pace/safety car on track and no cars may pass. However, if the safety car gives a green light, then the cars behind can pass the safety car (lapped cars only). Local caution condition —no cars may pass at the particular corner where being displayed. When Stationary indicates hazard off-course, when Waving indicates hazard on-course.
Yellow flag with red stripes Debris, fluid, or other hazard on the track surface. Debris, fluid, or other hazard on the track surface.
Black flag The car with the indicated number must pit for consultation. The session is halted, all cars on the course must return to the pit lane. May also be seen combined with a green flag to indicate oil on the track, typically referred to as a 'pickle' flag combination.
Meatball flag The car with the indicated number has mechanical trouble and must pit.
Black and white flag The driver of the car with the indicated number has been penalized for misbehaviour.
White cross flag The driver of the car with the indicated number is disqualified or will not be scored until they report to the pits.
Blue flag with yellow stripe The car should give way to faster traffic. This may be an advisory or an order depending on the series. A car is being advised or ordered to give way to faster traffic approaching.
Red flag The session is stopped. All cars must halt on the track or return to the pit lane.
White flag Depending on the series, either one lap remains or a slow vehicle is on the track. A slow vehicle is on the track.
Chequered flag The session has concluded.

Accidents

[edit]

The worst accident in racing history is the 1955 Le Mans disaster, where more than 80 people died, including the French driver Pierre Levegh.[18]

Racing-car setup

[edit]

In auto racing, the racing setup or car setup is the set of adjustments made to the vehicle to optimize its behaviour (performance, handling, reliability, etc.). Adjustments can occur in suspensions, brakes, transmissions, engines, tires, and many others.

Aerodynamics

[edit]

Aerodynamics and airflow play big roles in the setup of a race car. Aerodynamic downforce improves the race car's handling by lowering the center of gravity and distributing the weight of the car equally on each tire.[19] Once this is achieved, fuel consumption decreases and the forces against the car are significantly lowered. Many aerodynamic experiments are conducted in wind tunnels, to simulate real-life situations while measuring the various drag forces on the car.[20] These "Rolling roads" produce many wind situations and direct air flow at certain speeds and angles.[21] When a diffuser is installed under the car, the amount of drag force is significantly lowered, and the overall aerodynamics of the vehicle is positively adjusted.[20] Wings and canards channel the airflow in the most efficient way to get the least amount of drag from the car. It is experimentally proven that downforce is gained and the vehicle's handling is considerably changed when aerodynamic wings on the front and rear of the vehicle are installed.[20]

Suspension

[edit]

Suspension plays a huge part in giving the race car the ability to be driven optimally. Shocks are mounted vertically or horizontally to prevent the body from rolling in the corners. The suspension is important because it makes the car stable and easier to control and keeps the tires on the road when driving on uneven terrain. It works in three different ways including vertically, longitudinally, and laterally to control movement when racing on various tracks.[19]

Tyres

[edit]

Tyres called R-Compounds are commonly used in motorsports for high amounts of traction. The soft rubber allows them to expand when they are heated up, making more surface area on the pavement, therefore producing the most traction.[19] These types of tyres do not have grooves on them. Tyre pressure is dependent on the temperature of the tyre and track when racing. Each time a driver pulls into the pits, the tyre pressure and temperature should be tested for optimal performance. When the tyres get too hot they will swell or inflate and need to be deflated to the correct pressure.[19] When the tyres are not warmed up they will not perform as well.

Brakes

[edit]

Brakes on a race car are imperative in slowing and stopping the car at precise times and wear quickly depending on the road or track on which the car is being raced, how many laps are being run, track conditions due to weather, and how many caution runs require more braking. There are three variables to consider in racing: brake pedal displacement, brake pedal force, and vehicle deceleration.[22] Various combinations of these variables work together to determine the stiffness, sensitivity, and pedal force of the brakes. When using the brakes effectively, the driver must go through a buildup phase and end with a modulating phase. These phases include attaining maximum deceleration and modulating the brake pressure.[22] Brake performance is measured in bite and consistency. Bite happens when the driver first applies the brakes and they have not warmed up to the correct temperature to operate efficiently. Consistency is measured in how consistent the friction is during the entire time of braking. These two measurements determine the wear of the brakes.[22]

Engine

[edit]

The race car's engine needs a considerable amount of air to produce maximum power. The air intake manifold sucks the air from scoops on the hood and front bumper and feeds it into the engine. Many engine modifications to increase horsepower and efficiency are commonly used in many racing-sanctioning bodies.[19] Engines are tuned on a machine called a dynamometer, which is commonly known in the racing world as a DYNO. The car is driven onto the DYNO and many gauges and sensors are hooked up to the car that are controlled by an online program to test force, torque, or power. Through the testing, the car's engine maps can be changed to get the most horsepower and ultimately speed out of the vehicle.

Racing drivers

[edit]

Racing drivers, at the highest levels, can be paid by the team, or by sponsors, and can command substantial salaries. Drivers who pay for their positions, or seats, within racing teams are typically known as pay drivers, or gentleman drivers.[23] Drivers may also enter events as privateers.

Contrary to popular assumption, racing drivers as a group do not have unusually strong reflexes or peripheral response time.[24] During repeated physiological and psychological evaluations of professional racing drivers, the two characteristics that stand out are racers' near-obsessive need to control their surroundings—psychological—and an unusual ability to process fast-moving information —physiological. Researchers have noted a strong correlation between racing driver psychological profiles and those of fighter pilots. In tests comparing racing drivers to the general public, the greater the complexity of the information processing matrix, the greater the speed gap between the two groups.[25]

Due partly to the performance capabilities of modern racing cars, racing drivers require a high level of fitness, focus, and the ability to concentrate at high levels for long periods in an inherently difficult environment. They are often subject to injuries in the lumbar, shoulder, and neck regions.[26] Racing drivers experience large g-forces due to formula cars and sports prototypes generating high levels of downforce, and being able to corner at high speeds.[27] Formula One drivers routinely experience lateral loads in excess of 4.5 g (44 m/s2; 140 ft/s2), requiring drivers to commit to frequent neck training regimens.[28]

History

Origins in the late 19th century

The invention of the automobile is widely attributed to Karl Benz, who in 1885 constructed the Benz Patent-Motorwagen, a three-wheeled vehicle powered by a single-cylinder four-stroke gasoline engine, marking the first practical self-propelled road vehicle. This breakthrough, patented on January 29, 1886, as a "vehicle powered by a gas engine" (patent number 37435), ignited interest in motorized transport across Europe, particularly in France and Germany, where engineers and manufacturers sought to refine the technology for public roads. The Motorwagen's top speed of about 16 km/h and its successful test drives demonstrated the feasibility of automobiles, shifting perceptions from novelty to potential utility and sparking competitive demonstrations to showcase reliability and innovation. The first organized automobile competition emerged in 1894 with the Paris-Rouen Trial, a 126 km reliability event from to , , initiated by Giffard, editor of the newspaper Le Petit Journal, to celebrate the centenary of inventor and promote emerging automotive technology. Of 102 registered entries representing diverse propulsion methods—including , electric, , and even —only 21 vehicles qualified under basic safety and non-animal power criteria, with 17 completing the course after stops for mechanical issues and inspections. The event prioritized vehicle dependability over outright speed, lacking formal racing rules and emphasizing ease of operation, comfort, and safety; winners were declared based on a judging panel's assessment, with shared honors going to the -powered De Dion and -driven Type 5, both averaging under 20 km/h. This trial, held on July 22, 1894, drew massive public attention, boosting manufacturer prestige and encouraging tourism along the route by highlighting scenic French roadways. Building on this momentum, the 1895 Paris-Bordeaux-Paris race, also organized by Le Petit Journal, represented the first true endurance contest, covering 1,178 km round-trip over public roads in under 100 hours to test long-distance viability. Of around 46 entrants, 22 started after qualification, but only nine finished, with Émile Levassor winning in a et Levassor after 48 hours and 48 minutes, achieving an average speed of 24.4 km/h despite breakdowns, dust, and rudimentary repairs conducted roadside. The event underscored the promotional role of such races in advancing internal-combustion engines and designs, as manufacturers like and vied for technological superiority to attract investors and consumers in Europe. By 1900, international competition arrived with the inaugural Gordon Bennett Cup, held in France from Paris to Lyon over 566 km on June 14, organized by American newspaper publisher to foster global automotive progress through national team entries. Five cars started under ad-hoc rules limiting weight and emphasizing speed on timed public roads, with France's Fernand Charron victorious in a 40 hp et Levassor after 9 hours and 4 minutes, averaging about 62 km/h and securing prestige for French engineering amid growing manufacturer rivalries. These early events, driven by desires to validate automobile reliability, stimulate technological innovation, and enhance tourism via publicized routes, laid the groundwork for auto racing without standardized regulations, often relying on newspaper sponsorship for organization and publicity.

The early 20th century marked a pivotal phase in the professionalization of auto racing, driven by the establishment of international competitions that elevated the sport from localized events to a globally recognized spectacle. The Gordon Bennett Cup, initiated in 1900 and concluding in 1905, served as the inaugural international motor racing series, conceived by American newspaper publisher James Gordon Bennett Jr. to foster competition among nations. This event rotated annually across host countries—beginning in France in 1900, moving to Germany in 1901, Ireland in 1902 and 1903, Germany again in 1904, and returning to France in 1905—while emphasizing national teams rather than individual entrants, which heightened patriotic fervor and international prestige. By 1905, the cup had become the world's premier race, showcasing rapid advancements in automobile technology and drawing massive crowds, though its finale in Auvergne, France, highlighted the grueling nature of the courses with elimination trials and challenging terrain. Efforts to standardize the burgeoning sport led to the formation of the Association Internationale des Automobile Clubs Reconnus (AIACR) in 1904, an organization uniting national automobile clubs to establish uniform rules for competitions, licensing, and technical specifications. This body laid the groundwork for regulated international events, addressing the chaos of disparate national regulations that had previously hindered cross-border racing. Building on this framework, the first Grand Prix race emerged in 1906 as the , organized by the Automobile Club de France (ACF) on a 64-mile circuit of public roads near , spanning two days and covering over 760 miles. Hungarian driver Ferenc Szisz claimed victory in a AK, averaging around 59 mph, underscoring the event's role in promoting manufacturer innovation and endurance testing under controlled yet demanding conditions. Public safety concerns, amplified by catastrophic incidents in open-road races, prompted a critical shift from public highways to purpose-built circuits in the early 1900s. The 1903 Paris- race, organized by the ACF as a 807-mile endurance challenge from Versailles to , exemplified this danger when it resulted in at least eight fatalities—including drivers like Marcel and numerous spectators—due to high speeds on unprepared roads, leading to crashes into crowds and barriers. The event was halted prematurely at by French authorities, and the ensuing outrage prompted widespread bans on city-to-city road races across by mid-1903, as governments prioritized public welfare over the sport's spectacle. This tragedy accelerated the development of enclosed tracks, such as the UK's circuit in 1907, which became the world's first purpose-built motor racing venue, allowing safer, controlled high-speed racing while enabling promoters to monetize admissions.

Scoring systems

Scoring systems in auto racing determine race results and allocate points toward season-long championships, ensuring fair competition across various series governed by organizations like the FIA and . Race outcomes are primarily based on finishing order, which is established by the sequence in which vehicles cross the finish line after completing the prescribed number of laps, adjusted for any penalties such as time additions or position drops imposed by stewards for infractions like track limit violations or unsafe releases. Points are awarded to classified finishers based on their position, with structures varying by series but often following a descending scale to reward top performers. In FIA-sanctioned Formula 1, the standard points allocation for Grand Prix races awards 25 points to the winner, 18 to second place, 15 to third, and continues down to 1 point for tenth place, with no points for positions beyond tenth unless fewer than 10 cars are classified. These points contribute to both the Drivers' and Constructors' Championships, tallied cumulatively over the season's events, where the driver or constructor with the highest total at the end secures the title. Similarly, sprint races in select events award points on a reduced scale: 8 for first, 7 for second, down to 1 for eighth. In multi-class events like the , scoring is conducted separately within each category to account for differing vehicle types and performance levels, such as Hypercar prototypes versus LMGT3 grand tourers. Points are allocated per class, with scaling based on race duration—for example, 25 points for the top finisher in a 6-hour race, increasing to 50 for the —descending accordingly within each class and ensuring equitable championships for each division while cars compete simultaneously on track; additionally, as of 2025, drivers must complete at least 45 minutes of driving time to be eligible for points. Drivers who do not finish (DNF) a race receive zero points, significantly impacting their championship standings, as only classified finishers earn awards—for instance, in , those completing at least 90% of the winner's race distance, though requirements vary by series (e.g., 70% in WEC). Specific rules extend scoring's influence beyond immediate race results; for instance, in Formula 1, super licence points are awarded based on performance in lower formulas, with drivers needing at least 40 points accumulated over three seasons from series like Formula 2 or Formula 3 to qualify for an F1 super licence, emphasizing consistent excellence for eligibility. In NASCAR's Cup Series, stage points were introduced in 2017 to add competitive segments within races, awarding bonus points to the top-10 finishers at the end of predefined stages (typically two per race), plus 1 playoff point for stage winners, enhancing strategic depth and rewarding mid-race performance alongside the final finishing order. Electronic timing systems underpin these determinations with high precision, measuring lap times and photo-finishes to an accuracy of 0.001 seconds in major series like Formula 1 and , using technology and high-speed cameras to resolve disputes and ensure verifiable results. Flag signals from race control can indirectly affect scoring by altering race conditions, such as neutralizations that bunch the field and influence final positions.

Flag signals and procedures

Flag signals serve as the primary system in auto racing, alerting drivers to track conditions, hazards, and procedural directives to maintain and race integrity across various series. These signals, displayed by marshals at strategic points around the circuit, ensure that competitors respond promptly to changing circumstances without verbal instruction during high-speed sessions. While flag meanings are standardized under governing bodies like the FIA for international events, slight variations exist in series such as to accommodate oval-track dynamics. The core flag types include the green flag, which indicates the start of a race or session, or the resumption of racing after a caution period, allowing full-speed competition and overtaking. A yellow flag signals caution due to hazards like debris or incidents ahead, requiring drivers to slow down, avoid overtaking, and maintain position; a single waved yellow denotes a trackside hazard, while double waved indicates a more severe blockage. The red flag halts the session entirely, instructing drivers to reduce speed and return to the pit lane or stop safely, often due to major incidents or weather. The checkered flag marks the finish, signaling the end of the race or stage, with drivers required to complete the lap for official results.

Safety car procedures are integral to yellow flag responses, particularly for debris or minor incidents; in FIA-sanctioned series like Formula 1, a physical deploys to bunch the field at reduced speeds, allowing marshals to clear the track safely. The virtual safety car (VSC), introduced in F1 in 2015 following tests to address incidents without full bunching, imposes a delta time limit—typically requiring drivers to stay within 40 km/h above the minimum speed—across the circuit without a physical vehicle leading the pack. In NASCAR, the pace car fulfills a similar under , controlling speeds on ovals. Procedural flags guide specific actions: the blue flag, often with a yellow diagonal stripe, warns slower or lapped cars of approaching faster vehicles, requiring them to yield position without defending to facilitate passing and maintain race flow. Pit lane entry rules mandate controlled speeds—typically 60 km/h in FIA events—and single-file entry to prevent collisions, with closures enforced during red flags or high-risk cautions. A black flag with a white diagonal stripe serves as a warning for , such as , urging the driver to correct behavior without immediate penalty. Radio communications from race control supplement flags, providing verbal clarifications on complex situations like penalty enforcement or track-specific hazards, ensuring drivers receive real-time updates beyond visual signals. In the evolution of these systems, LED panels began replacing traditional cloth flags in the for improved visibility and reliability; for instance, adopted digital marshalling panels in 2022 to reduce driver distraction and enhance precision in flag display.

Safety

Notable accidents and fatalities

Auto racing has long been associated with significant risks to drivers, marshals, and spectators, with notable accidents underscoring the sport's perilous nature and prompting critical safety discussions. The 1955 stands as the deadliest incident in motorsport history, where a collision between Pierre Levegh's and Lance Macklin's caused Levegh's car to launch into the air, disintegrate upon impact with the barrier, and scatter flaming debris into the spectator stands, resulting in 83 fatalities, including Levegh and 82 spectators. This catastrophe, exacerbated by inadequate barriers and the proximity of crowds to the track, severely damaged the sport's public image and led to temporary bans on motorsport in several countries. In Formula 1, the 1970s marked a particularly grim era, with 12 driver fatalities amid rapid technological advancements and insufficient safety measures. , the 1970 World Champion posthumously awarded after his death, perished during qualifying for the at when his Lotus 72's front wing failed, sending the car into the barriers at high speed and causing fatal injuries from the subsequent impact. Other tragedies in this decade, such as the deaths of at Zandvoort in 1970 due to a fiery crash from barrier contact and at Watkins Glen in 1973 from a high-speed shunt, highlighted recurring issues like flimsy guardrails and fire hazards. By 1994, Formula 1 had claimed over 45 driver lives since 1950, with the San Marino Grand Prix weekend at Imola epitomizing the era's dangers: Austrian rookie Roland Ratzenberger died in qualifying from a steering failure-induced crash into the Villeneuve corner wall, followed the next day by Ayrton Senna's fatal impact at Tamburello, where a suspected steering column fracture caused his Williams to veer off-track at 211 km/h, resulting in a piece of suspension piercing his helmet. Senna's death, as one of the sport's most iconic figures, profoundly shocked global audiences and intensified scrutiny on circuit design and car integrity. Stock car racing also faced devastating losses, exemplified by Dale Earnhardt's death on February 18, 2001, during the final lap of the Daytona 500. The seven-time champion's No. 3 Chevrolet collided with Sterling Marlin's car, then hit the Turn 4 wall at nearly 160 mph, suffering a from the head-on impact despite his seatbelt; he was pronounced dead at the hospital. This incident, the first fatality in 's top series in over five years, drew widespread media attention and eroded fan confidence in the sport's safety. Common causes in these accidents included mechanical failures like steering or brake issues, inadequate barriers that failed to contain high-speed impacts, and tire problems leading to loss of control, as seen in various Formula 1 shunts. Even in the , junior series have not been immune, with 18-year-old Dutch driver dying in a multi-car pileup during a rain-affected race at Spa-Francorchamps in July 2023, triggered by and poor visibility. Such events have continued to influence public perception, portraying auto racing as inherently risky despite progress, and have spurred brief references to regulatory responses like enhanced track runoff areas. Overall, auto racing fatalities have declined markedly, with Formula 1 recording 14 driver deaths in the compared to just one since 2014 ( in 2014), reflecting a drop in annual fatality rates from approximately 1.4 per season in the to near zero in recent decades across major series. This evolution, driven by lessons from these tragedies, has transformed the sport from one where 47 drivers perished in F1-related incidents before to a safer discipline by 2025.

Safety innovations and regulations

Safety innovations in auto racing have significantly reduced fatalities and injuries through advancements in , vehicle modifications, and infrastructure enhancements. One pivotal development in driver gear is the Head and Neck Support () device, introduced mandatorily in in 2001 following the , which tethers the driver's helmet to the shoulder harness to limit head movement during impacts and prevent basilar skull fractures. Fire-resistant suits, made from materials like , emerged in the mid-1960s after a series of fiery crashes highlighted the need for better thermal protection, becoming standard equipment to give drivers precious seconds to escape burning vehicles. Additionally, gear tailored for women addresses anatomical differences, such as narrower shoulders and hips, to ensure proper fit of suits, harnesses, and seats, thereby improving restraint effectiveness and reducing injury risk during collisions. Vehicle design features have also evolved to prioritize occupant protection. Roll cages, which provide a rigid framework to prevent roof collapse in rollovers, became mandatory in major series like USAC Champ Car racing by 1959 and for sprint cars by 1971, and across international events under FIA rules by 1971, stemming from numerous fatal overturns in the preceding decades. In open-wheel racing, the FIA-mandated halo device—a bar encircling the —was implemented in 2018 to shield drivers' heads from debris and penetrating objects, crediting it with saving lives in at least eight high-profile incidents by 2024, including those involving and . Trackside improvements focus on energy absorption to mitigate crash forces. The Steel and Foam Energy Reduction (SAFER) barrier, developed through collaborative research in the 1990s by , , and universities, uses a steel-faced structure to dissipate impact , first installed at in 2002 and now standard at oval tracks hosting major events. Complementary features like extended runoff areas and tire walls provide deceleration zones, reducing the severity of off-track excursions. Regulatory frameworks enforce these innovations globally. The FIA's Appendix J to the outlines technical standards for safety equipment, including specifications for cages, restraints, and across racing categories. Medical protocols require on-site response teams equipped with advanced life-support ambulances and helicopters for rapid evacuation, as seen in series like Formula 1 and , where ensure transport to trauma centers within the golden hour.

Vehicle design and setup

Aerodynamics

Aerodynamics in auto racing focuses on managing around vehicles to generate , which increases grip and cornering speeds, while minimizing drag to enhance straight-line . is primarily produced using inverted airfoils, such as wings, that create low-pressure areas above the car and high-pressure areas below, pushing the vehicle toward the track surface. Drag reduction is achieved through smooth underbody designs that promote and reduce , allowing cars to reach higher speeds with less power. These principles balance the trade-off between , which aids handling but increases drag, and overall performance optimization. Key aerodynamic components include front and rear wings, which adjust airflow to produce targeted downforce; diffusers at the rear that accelerate exhaust air to create suction; and bargeboards, which condition turbulent air from the front wing to improve flow over the sidepods. In the 1970s, ground effect aerodynamics emerged with the Lotus 78 Formula 1 car, utilizing venturi tunnels under the sidepods and sliding skirts to seal low-pressure zones close to the ground, generating substantial downforce with reduced drag compared to traditional wings. This innovation revolutionized racing by enabling higher cornering speeds without excessive top-speed penalties. Aerodynamic development relies on testing, where scaled models are subjected to controlled airflow to measure forces and visualize flow patterns, and (CFD) simulations, which predict airflow behavior through numerical modeling for rapid iterations. In Formula 1, regulations enforced by the FIA limit aerodynamic flexibility, including bans on adjustable wing elements beyond specified zones and restrictions on overall car width and underbody profiles to promote closer . Active aerodynamics, which allowed movable components like adjustable front wings, was prohibited starting in 2009 to reduce complexity and costs while enhancing . Modern Formula 1 cars can generate equivalent to about five times their weight—around 4,000 kg total vertical load—at speeds of 300 km/h, enabling sustained cornering at forces up to . Aerodynamic optimization contributes significantly to performance, with reductions in potentially increasing lap times by over 20 seconds on a typical circuit, underscoring its role in achieving lap time gains through balanced and drag management. These designs integrate with suspension systems to translate aerodynamic loads into mechanical grip, though the primary focus remains on airflow control.

Suspension and chassis

The suspension and chassis in auto racing form the foundational structure that supports the vehicle's components while managing dynamic forces during high-speed maneuvers. The primary role of the suspension system is to absorb impacts from road irregularities, such as bumps and curbs, while ensuring continuous contact with the surface to maximize grip and stability. This is achieved through a combination of springs, dampers, and linkages that control weight transfer during , braking, and cornering, thereby optimizing handling without compromising driver control. Chassis designs vary by racing discipline to balance rigidity, weight, and safety. In Formula 1, the chassis—introduced with carbon fiber composites in the early , notably McLaren's MP4/1 in 1981—serves as a lightweight, high-stiffness survival cell that integrates the driver's cockpit and withstands extreme loads. This single-piece structure must pass rigorous FIA crash tests, including frontal, side, and rear impacts, to limit deformation and protect occupants. In contrast, NASCAR stock cars employ a spaceframe , consisting of a tubular steel that provides structural integrity and energy absorption during collisions, while adhering to series-specific dimensional and material standards. Suspension setups are engineered for precise wheel control and compliance with regulations. The double wishbone configuration, widely used in open-wheel and , employs upper and lower A-arms to allow independent wheel movement, enabling fine-tuned camber and adjustments for enhanced cornering precision and reduced tire scrub. systems, which use electronics to adjust and in real-time, were pioneered in the 1980s but banned by the FIA in 1994 across major series due to concerns over escalating speeds and safety risks; only passive mechanical systems are permitted today. Teams fine-tune suspension geometry for specific track conditions through adjustments to camber (wheel tilt relative to vertical), (steering axis inclination), and (wheel angle relative to the centerline). Negative camber improves cornering grip by increasing the outer tire's under lateral load, while positive enhances straight-line stability and steering return; settings minimize drag on straights or promote turn-in responsiveness. These parameters are optimized pre-race to complement aerodynamic , ensuring the chassis responds effectively to varying loads. In rally racing, suspensions feature long-travel shocks to handle rough terrain, with travel distances reaching up to 300 mm in specialized setups to maintain traction over jumps and . Regulations impose flex limits to prevent unfair advantages or issues; for instance, the FIA mandates that F1 bodywork and components exhibit no more than specified deflection under load tests, typically 10-20 mm depending on the element, to preserve structural integrity. Similar constraints in ensure the spaceframe remains within approved tolerances during inspections.

Tires

In auto racing, tires are essential for providing traction, influencing vehicle handling, and determining race strategy through their selection and management. Slicks are used for dry conditions to maximize grip on the track surface, while wet tires, including intermediates for light rain or drying tracks and full wets for heavy rain, feature treads to displace water and prevent . Tire compounds vary from soft, which offer superior initial grip but rapidly, to hard, which prioritize durability for longer stints at the cost of peak performance. In Formula 1, supplies six slick compounds labeled C0 (hardest) to C5 (softest), with three selected per race weekend—typically a soft (red sidewall), medium (yellow), and hard (white)—to balance speed and longevity based on track characteristics. Soft compounds can degrade after approximately 10-15 laps on abrasive circuits, while harder ones may last 20 laps or more, depending on factors like track surface and driving style. Pirelli has been the exclusive tire supplier to Formula 1 since 2011, providing tires for 18-inch rims as mandated by regulations introduced in 2022 to improve aesthetics and performance. In the (WEC), serves as the exclusive supplier for the Hypercar class through at least 2029, offering similar slick and wet options tailored for endurance racing. pressures are strictly regulated for safety and performance, typically ranging from 20-25 psi at the rear and slightly higher at the front to optimize and heat buildup. Effective management involves warm-up procedures during formation laps, where drivers weave and lightly to raise temperatures without excessive wear, ensuring optimal grip from the start. Teams employ degradation models to predict life and plan pit stops, factoring in variables like track temperature and load to minimize performance loss over a stint. Run-flat , which allows continued driving after punctures, has been used in series like the until but is less common in modern open-wheel racing due to weight and cost concerns. Tire grip varies significantly with operating temperature, peaking at 90-110°C where the rubber achieves ideal viscoelastic properties for maximum ; deviations can reduce grip by up to 20% through decreased contact conformance or overheating. Brake during hard stops can further influence tire temperatures, tying into overall thermal management strategies addressed in braking systems.

Brakes

In auto racing, brakes are critical stopping systems engineered for extreme performance, converting into through while enduring repeated high-speed applications without failure. These systems prioritize materials and high thermal capacity to handle decelerations far beyond road vehicles, often generating temperatures exceeding 800°C in short bursts. Disc brakes dominate professional series due to their superior and modulation compared to designs, with hydraulic actuation providing precise control. Key components include carbon-carbon composite discs and multi-piston calipers. In Formula 1, front discs typically measure 328 mm in diameter with a maximum thickness of 32 mm, made from carbon fiber that withstands peak temperatures up to 1,000°C to prevent warping or cracking under load. Calipers, typically forged aluminum, feature up to six pistons per wheel to evenly distribute clamping force on the pads and discs, maximizing friction while minimizing weight; this configuration is mandated as the maximum by FIA regulations. Advanced braking systems in modern racing incorporate electronic aids selectively, with anti-lock braking systems (ABS) prohibited in most professional series like Formula 1 to emphasize driver skill in modulating pressure and avoiding wheel lockup. In hybrid-era vehicles, such as those in Formula 1 since 2014, technology integrates from the MGU-K energy recovery system, electronically adjusting rear brake bias for optimal energy harvest without compromising pedal feel. Effective cooling is essential to maintain performance, particularly through aerodynamic ducts that channel air to the discs and calipers, often via over 1,000 ventilation holes drilled into the disc surface. In endurance racing like the , where continuous high loads can push disc temperatures to 1,000°C, fade resistance— the system's ability to sustain friction despite heat buildup—proves vital, with designs emphasizing rapid heat dissipation to avoid progressive loss of over hours. Formula 1 brakes exemplify these demands, achieving decelerations of 5-6G, equivalent to forces over 100 kg on the pedal, limited primarily by grip rather than the braking hardware itself. materials have evolved significantly for safety and performance; early racing pads relied on for heat resistance until health concerns prompted a shift in the to non-asbestos organics, followed by Kevlar-reinforced composites in the for superior durability and fade resistance without carcinogenic risks.

Engines and powertrains

In auto racing, engines and powertrains serve as the core systems, converting fuel or into mechanical power to drive vehicles at high speeds while adhering to series-specific regulations for performance, efficiency, and sustainability. These systems have evolved from traditional internal combustion engines to advanced hybrids, balancing raw power output with energy recovery and environmental goals. Major series like Formula 1 and emphasize hybrid turbocharged V6 configurations, while relies entirely on electric motors, showcasing diverse approaches to in circuit, oval, and . Formula 1 power units feature a 1.6-liter turbocharged V6 internal combustion engine paired with hybrid components, delivering a total output exceeding 1,000 horsepower, with the combustion engine alone producing approximately 840 horsepower and the electric systems adding up to 160 horsepower. IndyCar employs a 2.2-liter twin-turbocharged V6 engine with hybrid assist, generating around 700 horsepower from the combustion element and up to 900 horsepower combined during peak deployment on ovals and road courses. In contrast, Formula E uses battery-powered electric motors in its Gen3 cars, providing 300 kilowatts (about 402 horsepower) in standard race mode and up to 350 kilowatts in attack mode for temporary boosts. Energy recovery systems (ERS) are integral to modern hybrid powertrains, particularly in Formula 1, where the motor generator unit-kinetic (MGU-K) recaptures kinetic energy during braking at rates up to 400 kilowatts, though deployment is limited to 120 kilowatts to store usable electrical energy in the battery for later acceleration boosts. The MGU-heat (MGU-H) further enhances efficiency by recovering waste heat from the turbocharger exhaust, contributing to overall thermal efficiencies exceeding 50% in current V6 hybrids—a benchmark that nearly doubles typical road car engines and supports Formula 1's sustainability push. Fuels play a key role, with Formula 1 mandating E10 blends (90% fossil-based and 10% renewable ethanol) since 2022, paving the way for 100% sustainable drop-in fuels by 2026 to reduce carbon emissions without altering engine designs. IndyCar and other series are exploring similar biofuel integrations to align with efficiency targets, including 50% thermal efficiency in hybrid systems by 2025. Drivetrain configurations vary by discipline to optimize traction and handling; rear-wheel drive remains standard in circuit-based series like Formula 1 and for its simplicity and weight distribution benefits, channeling power directly to the rear via a layout. In rally racing, such as the FIA , all-wheel drive is prevalent, distributing torque to all four wheels for superior grip on loose surfaces like or , often through adjustable differentials that enhance cornering stability. Engine tuning via (ECU) mapping refines power delivery by adjusting parameters like timing, ignition advance, and turbo boost to shape the power curve—optimizing across RPM ranges for track-specific demands, such as low-end pull for or high-rev peaks for top speed. In , these maps are iteratively refined during testing to maximize usable power without exceeding regulatory limits, ensuring consistent under varying conditions like temperature or fuel quality.

Participants

Racing drivers

Professional racing drivers in auto racing must meet varying requirements depending on the discipline, with high-level series like Formula 1 imposing stringent criteria. The (FIA) mandates a Super Licence for Formula 1 participation, which requires drivers to accumulate at least 40 points over a three-year period from approved junior single-seater championships, hold an International Grade A competition licence, possess a valid road driving licence, and be at least 18 years old on the of their first Grand Prix. Additionally, they must pass an FIA theory test on Formula 1 sporting codes and regulations. In other series, such as , drivers need a competition license from sanctioning bodies like , often starting with regional events. Physical fitness is paramount across disciplines, with Formula 1 drivers needing exceptional neck strength to withstand lateral G-forces up to during cornering and braking, often training to exert over 100 pounds of pressure to maintain head control. Rally drivers, by contrast, endure high-impact forces and require endurance for multi-day events. Training regimens for racing drivers emphasize both technical proficiency and resilience. Drivers typically spend several hours per week in advanced simulators to replicate race conditions, practicing vehicle handling and strategy for up to eight hours a day during preparation phases. Mental preparation is equally critical, involving visualization techniques, , and to make split-second decisions under pressure, such as during overtakes or tire management. These skills enable drivers to optimize performance, briefly tying into design elements like for better control at high speeds. Career paths in auto racing often begin in karting as early as age six, progressing through feeder series such as , , and Formula 2 before reaching Formula 1, a journey that can span over a decade. In , paths may start in local short tracks leading to NASCAR's lower divisions. Upon securing a seat, drivers sign multi-year contracts with teams, earning salaries ranging from about $1 million for rookies to $50 million or more for top stars, supplemented by performance bonuses. Iconic figures like , who joined Ferrari in 2025, exemplify success, having won a record-tying seven World Drivers' Championships. However, diversity remains a challenge, with women and minorities facing underrepresentation—as of 2020, less than 1% of Formula 1 personnel from Black or minority ethnic backgrounds—and barriers like stereotypes and limited access to junior programs, though recent diversity charters aim to address this. Specific aspects of a driver's include an average length of 10-15 years in top-tier series, influenced by performance and , after which many transition to other motorsports or roles. For example, rally drivers like have careers spanning decades across WRC events. Biometric monitoring via sensors in gloves tracks like and blood oxygen levels during races, allowing teams to assess driver and adjust strategies accordingly.

Teams and organizations

Auto racing teams operate as complex organizations with varying scales depending on the discipline, particularly in high-profile series like Formula 1 employing over 1,000 personnel across factory and track roles, including specialized positions such as race engineers—who monitor vehicle performance in real-time—and strategists who analyze race data to optimize decisions. In endurance racing like , teams manage multi-driver lineups and larger crews for 24-hour events. Budgets for top Formula 1 teams surpass $100 million annually, constrained by a financial cost cap set at €140.4 million (about $152 million) for 2024, excluding driver salaries and certain marketing expenses. This cap aims to promote competitive balance by limiting excessive spending on development and operations; for 2025, it is approximately €135 million base adjusted for inflation. Funding for racing teams relies heavily on sponsorships and manufacturer backing, which provide the bulk of beyond . Sponsorship deals, often featuring prominent on team liveries and , have evolved due to regulatory changes; for instance, the imposed a ban on advertising in effective July 31, 2005, forcing teams to diversify away from such high-value partners previously dominant in the sport. Manufacturers play a pivotal role in and , with Ferrari exemplifying deep integration by producing Formula 1 power units and chassis components alongside its road car lineup at its historic facility, ensuring synergies in . In , teams like receive support from automotive giants like Chevrolet. Governing organizations oversee the sport's framework, with the Fédération Internationale de l'Automobile (FIA) serving as the primary international body responsible for establishing and enforcing technical and sporting regulations across disciplines. The FIA develops rulebooks covering vehicle specifications, safety standards, and competition formats, while also licensing events and participants to maintain uniformity. National bodies like NASCAR's sanctioning organization handle series-specific rules. Series promoters, such as —which acquired Formula 1 in January 2017 for an enterprise value of $8 billion—handle commercial aspects like broadcasting rights, event organization, and global marketing to drive the sport's expansion and revenue. Team operations emphasize precision and technology, with Formula 1 pit crews achieving tire changes in as little as 1.90 seconds during the 2024 season, showcasing rigorous and to minimize time loss. In , crew efficiency focuses on rapid vehicle launches rather than stops. Data analytics forms the backbone of strategic decision-making, as teams process vast datasets from over 300 sensors per car—generating up to 1.5 terabytes per race weekend—to simulate scenarios, predict degradation, and refine timing. Real-time tactics are communicated via team radio systems, enabling engineers to relay adjustments for track conditions or rival moves directly to drivers. Partnerships, such as Honda's agreement to supply power units to starting in 2026, illustrate how manufacturers collaborate with teams to share expertise and resources in engine development.
