Auto racing (also known as car racing, motor racing, 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.
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 Classic 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.
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. It ran from Neuilly Bridge to the Bois de Boulogne.
On July 22, 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.
The first American automobile race is generally considered to be the Thanksgiving Day Chicago Times-Herald race of November 28, 1895. Press coverage of the event first aroused significant American interest in the automobile.
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. It featured a 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 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.
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 Grand tourer, with the italic=no (FIA) replacing the World Championship for Sports Cars with the International Championship for GT Manufacturers.
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. The European races eventually became the closely related European Le Mans Series, both of which mix prototypes and GTs.
italic=no (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. The industry, much like the it , has had to navigate through a global pandemic and a persistent chip shortage, each threatening to derail production schedules. 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.
Formula One is a worldwide series that runs only street circuit and . 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). 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 Two (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.
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 and Club Formula Ford. 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.
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.
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 , 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 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.
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.
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 Banger racing, 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.
When launching, a top fuel dragster will accelerate at 3.4 g-force (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 away and can generate a reading from 1.5 to 3.9 on the Richter scale.
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.
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".
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).
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.
In some series, points are also awarded based on lap leading, lap times, overtaking and qualifying positions (in particular by achieving and ). 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.
The session has started or resumed after a full course caution or stop. | End of the hazardous section of the track. | |
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 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.

Contrary to popular assumption, racing drivers as a group do not have unusually strong reflexes or reaction time. 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.
Due partly to the performance capabilities of modern racing cars, racing drivers require a high level of Physical fitness, focus, and the ability to concentrate at high levels for long periods in an inherently difficult environment. They often complain about injuries in the lumbar, shoulder, and neck regions. Racing drivers experience large due to formula racing and generating high levels of downforce, and being able to corner at high speeds. Formula One drivers routinely experience lateral loads in excess of , requiring drivers to commit to frequent neck training regimens.
