Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 1⁄4mi (1,320ft; 402m), with a shorter, 1,000ft (0.19mi; 304.80m) distance becoming increasingly popular, as it has become the standard for Top Fueldragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 1⁄8mi (660ft; 201m) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.
The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport.

To achieve high acceleration, drag racers have large tires, and the tires often "burn rubber" by friction with the pavement before the start, in order to heat and soften the tread surface of the tires.

History
Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned aircraft bases with landing strips that made them an ideal place for the sport. In 1951, Wally Parks formed the National Hot Rod Association (NHRA).[1][2] The organization banned the use of nitromethane in 1957, calling it unsafe, in part through the efforts of C. J. Hart; the ban would be lifted in 1963.[3]
Several other racing organizations were created over the past several decades, such as the Professional Drag Racers Association (PDRA) founded in 2014.[4][bettersourceneeded]
Thanks, in part, to the Discovery series Street Outlaws, fandom for drag racing has seen a resurgence in the past decade.[citation needed]
Push starts to get engines running were necessary until the National Hot Rod Association (NHRA) mandated self-starters in 1976.[5] After burnouts, cars would be pushed back by crews; this persisted until NHRA required reversing systems in 1980.[5]Don Garlits was the first to do burnouts across the starting line, which is now standard practice.[6] Each driver then backs up to and stages at the starting line.
Prerace preparations
Before each race (commonly known as a pass), each driver is allowed to perform a burnout, which heats the driving tires and lays rubber down at the beginning of the track, improving traction. The cars run through a "water box" (formerly a "bleach box", before bleach was replaced[when?] by flammable traction compound, which produced spectacular, and dangerous, flame burnouts; the hazard led NHRA to mandate use of water in the 1970s[6]).
Modern races are started electronically by a system known as a Christmas tree, which consists of a column of lights for each driver/lane, and two light beam sensors per lane on the track at the starting line. Current NHRA trees, for example, feature one blue light (split into halves), then three amber, one green, and one red.[7] When the first light beam is broken by a vehicle's front tire(s), the vehicle is "pre-staged" (approximately 7 inches (180mm) from the starting line), and the pre-stage indicator on the tree is lit. When the second light beam is broken, the vehicle is "staged", and the stage indicator on the tree is lit.[8] Vehicles may then leave the pre-stage beam, but must remain in the stage beam until the race starts.
Staging
Once one competitor is staged, their opponent has a set amount of time to stage or they will be instantly disqualified, indicated by a red light on the tree. Otherwise, once both drivers are staged, the system chooses a short delay at random (to prevent a driver being able to anticipate the start), then starts the race. The light sequence at this point varies slightly. For example, in NHRA Professional classes, three amber lights on the tree flash simultaneously, followed 0.4 seconds later by a green light (this is also known as a "pro tree"). In NHRA Sportsman classes, the amber lights illuminate in sequence from top to bottom, 0.5 seconds apart, followed 0.5 seconds later by the green light (this is also known as a "sportsman tree" or "full tree"). If a vehicle leaves the starting line before the green light illuminates, the red light for that lane illuminates instead, and the driver is disqualified (also known as red lighting). In a handicap start, the green light automatically lights up for the first driver, and the red light is only lit in the proper lane after both cars have launched if one driver leaves early, or if both drivers left early, the driver whose reaction time is worse (if one lane has a -.015 and the other lane has a -.022, the lane of the driver who committed a 0.022 is given the red light after both cars have left), as a red light infraction is only assessed to the driver with the worse infraction, if both drivers leave early. Even if both drivers leave early, the green light is automatically lit for the driver that left last, and they still may win the pass (as in the 2014 NHRA Auto Club Pro Stock final, Erica Enders-Stevens and Jason Line both committed red light infractions; only Line was assessed with a red light, as he was -.011 versus Enders-Stevens' -.002).
Measurements
Several measurements are taken for each race: reaction time, elapsed time, and speed. Reaction time is the period from the green light illuminating to the vehicle leaving the staging beams or breaking the guard beam. Elapsed time is the period from the vehicle leaving the starting line to crossing the finish line. Speed is measured through a speed trap covering the final 66 feet (20m) to the finish line, indicating average speed of the vehicle in that distance.
Except where a breakout rule is in place, the winner is the first vehicle to cross the finish line, and therefore the driver with the lowest combined reaction time and elapsed time. Because these times are measured separately, a driver with a slower elapsed time can actually win if that driver's advantage in reaction time exceeds the elapsed time difference. In heads-up racing, this is known as a holeshot win.[9] In categories where a breakout rule is in effect (for example, NHRA Junior Dragster, Super Comp, Super Gas, Super Stock, and Stock classes, as well as some dial-in classes), if a competitor is faster than his or her predetermined time (a "breakout"), that competitor loses. If both competitors are faster than their predetermined times, the competitor who breaks out by less time wins. Regardless, a red light foul is worse than a breakout, except in Junior Dragster where exceeding the absolute limit is a cause for disqualification.
Bracket system
Most race events use a traditional bracket system, where the losing car and driver are eliminated from the event while the winner advances to the next round, until a champion is crowned. Events can range from 16 to over 100 car brackets. Drivers are typically seeded by elapsed times in qualifying. In bracket racing without a breakout (such as NHRA Competition Eliminator), pairings are based on times compared to their index (faster than index for class is better). In bracket racing with a breakout (Stock, Super Stock, but also the NHRA's Super classes), the closest to the index is favorable.
A popular alternative to the standard eliminations format is the Chicago Style format (also called the Three Round format in Australia), named for the US 30 Dragstrip near Merrillville, Indiana where a midweek meet featured this format.[10] All entered cars participate in one qualifying round, and then are paired for the elimination round. The two fastest times among winners from this round participate in the championship round. Depending on the organization, the next two fastest times may play for third, then fifth, and so forth, in consolation rounds. Currently, the National Drag Racing Championship in Australia uses the format for major categories.[11]
Distances
The standard distance of a drag race is 1,320 feet, 402m, or 1/4 mile (±0.2% FIA & NHRA rules). However, due to safety concerns, certain sanctioning bodies (notably the NHRA for its Top Fuel and Funny Car classes) have shortened races to 1,000 feet. Some drag strips are even shorter and run 660 feet, 201m, or 1/8 mile. The 1,000 foot distance is now also popular with bracket racing, especially in meets where there are 1/8 mile cars and 1/4 mile cars racing together, and is used by the revived American Drag Racing League for its primary classes (not Jr Dragster). Some organizations that deal with Pro Modified and "Mountain Motor" Pro Stock cars (Professional Drag Racers Association) use the 1/8 mile distance, even if the tracks are 1/4 mile tracks.

The World Drag Racing Alliance (WDRA) WDRA is the first fully functioning sanctioning body created (one that actually sanctions facilities) since 1970.
Besides NHRA, IHRA, and WDRA, there are several other racing organizations were created over the past several decades. The Professional Drag Racers Association (PDRA), founded in 2014, races 1/8 mile with events throughout the US. The National Mustang Racers Association (NMRA), started in 1999, is considered the leader in Ford motorsports events.[12] The National Muscle Car Association (NMCA), is the longest running major street-legal drag racing association. The NMCA provides competitive and organized national event competitions from grassroots drag racers all the way to the powerful and fast VP Racing Fuels Xtreme Pro Mod racers.[13]
There are also niche organizations for muscle cars and nostalgia vehicles. The Nostalgia Drag Racing League (NDRL) based in Brownsburg, IN, runs a series of 1/4 mile (402m) drag races in the Midwest for 1979 and older nostalgic appearing cars, with four classes of competition running in an index system. Pro 7.0 and Pro 7.50 run heads up 200 mile per hour (320 kilometre per hour) passes, while Pro Comp and Pro Gas run 8.0 to 10.0 indices. NDRL competition vehicles typically include Front Engine Dragsters, Altereds, Funny Cars, early Pro Stock clones, Super Stocks and Gassers.[14]
The National Electric Drag Racing Association (NEDRA) races electric vehicles against high performance gasoline-powered vehicles such as Dodge Vipers or classic muscle cars in 1/4 and 1/8mile (402m & 201m) races. The current electric drag racing record is [15] 6.940 seconds at 201.37mph (324.0736km/h) for a quarter mile (402m). Another niche organization is the VWDRC which run a VW-only championship with vehicles running under 7 seconds.
Prior to the founding of the NHRA and IHRA, smaller organizations sanctioned drag racing in the early years, which included the competing AHRA in the United States and Canada from 1955 to 2005.
Australia

The first Australian Nationals event was run in 1965 at Riverside raceway, near Melbourne. The Australian National Drag Racing Association (ANDRA) was established in 1973, and today they claim they are the "best in the world outside the United States".[16] ANDRA sanctions races throughout Australia and throughout the year at all levels, from Junior Dragster to Top Fuel.
The ANDRA Drag Racing Series is for professional drivers and riders and includes Top Fuel, Top Alcohol, Top Doorslammer (similar to the USA Pro Modified class), Pro Stock (using 400 cubic inch engines (6.5 litres)), Top Bike and Pro Stock Motorcycle.
The Summit Sportsman Series is for ANDRA sportsman drivers and riders and includes Competition, Super Stock, Super Compact, Competition Bike, Supercharged Outlaws, Top Sportsman, Modified, Super Sedan, Modified Bike, Super Street and Junior Dragster.
In 2015, after a dispute with ANDRA, Sydney Dragway, Willowbank Raceway and the Perth Motorplex invited the International Hot Rod Association (IHRA) to sanction events at their tracks. Shortly thereafter the Perth Motorplex reverted to ANDRA sanction. Although greatly assisted by ANDRA prior to its construction, Springmount Raceway opted for IHRA sanction. The 400 Thunder Series targets professional racers to its races. Intended to be the premier Drag racing series in Australia it has never been able to run a truly National series and has been on a steady decline since its inception. Most recently Top Fuel Australia (the organization that represents the Top Fuel owners) recently extracted itself from the 400 Thunder series. ANDRA recently launched a new National series that will initially cater for Top Doorslammer and Top Fue Motorcycle. This series will provide a greater National coverage than the 400 Thunder Series did and will soon add other Professional categories. In 2021 Heathcote Park Raceway in Victoria was sold to new ownership and has since been sanctioned by IHRA for small regional events.
Europe

Drag racing was imported to Europe by American NATO troops during the Cold War.[17] Races were held in West Germany beginning in the 1960s at the airbases at Ramstein and Sembach[18] and in the UK at various airstrips and racing circuits[19] before the opening of Europe's first permanent drag strip at Santa Pod Raceway in 1966.
The FIA organises a Europe-wide four wheeled championship for the Top Fuel, Top Methanol Dragster, Top Methanol Funny Car, Pro Modified and Pro Stock classes. FIM Europe organises a similar championship for bike classes. In addition, championships are run for sportsman classes in many countries throughout Europe by the various national motorsport governing bodies.
New Zealand
Drag racing in New Zealand started in the 1960s. The New Zealand Hot Rod Association (NZHRA) sanctioned what is believed to have been the first drag meeting at an open cut coal mine at Kopuku, south of Auckland, sometime in 1966. In 1973, the first and only purpose built drag strip opened in Meremere by the Pukekohe Hot Rod Club. In April 1993 the governance of drag racing was separated from the NZHRA and the New Zealand Drag Racing Association (NZDRA) was formed. In 2014, New Zealand's second purpose built drag strip – Masterton Motorplex – opened.
The first New Zealand Drag Racing Nationals was held in the 1966/67 season at Kopuku, near Auckland.
There are now two governing bodies operating drag racing in New Zealand with the Florida-based International Hot Rod Association sanctioning both of New Zealands major tracks at Ruapuna (Pegasus Bay Drag Racing Association Error in Webarchive template: Empty url.) in the South Island and Meremere Dragway Inc in the North Island which is now become the best drag strip in NZ. However, the official ASN of the sport, per FIA regulations, is the New Zealand Drag Racing Association.
South America

Many countries in South America race 200 meters, unlike in the United States, Canada and Australia, where the quarter-mile, or, 400 meters, respectively, is typical.
Organized drag racing in Brazil is the responsibility of Club G3, a private organization. The events take place at Autódromo de Tocancipá.[citation needed]
On the island of Curaçao, organization of drag racing events is handled by the Curaçao Autosport Foundation (FAC)[20] All racing events, including street legal competitions, happen at the Curaçao International Raceway.
Aruba
On the island of Aruba, all racing events, including street legal competitions, happen at Palomarga International Raceway.[21]
Barbados
On the island of Barbados, organization of drag racing events is done by the Barbados Association of Dragsters and Drifters.[22] Currently the drag racing is done at Bushy Park racing circuit[23] over 1/8 mile, while "acceleration tests" of 1/4 mile are done at the Paragon military base.
Saint Lucia
On the Island of Saint Lucia, organization of drag racing events is done by no-one. All local groups are tie ups. Currently races are held at the US Old military base also known as the "Ca Ca Beff", "The Base" near the Hewanorra International Airport in Vieux Fort.
Dominican Republic
On Santo Domingo, organization of drag racing events is done by Autodromo Sunix and they happen at the Autodromo Sunix, close to the Airport SDQ.

Organized drag racing is rapidly growing in India. The country's first drag race meet was organized by Autocar India in Mumbai in 2002. Since then there have been many drag racing events in India. The most popular event is Elite Octanes' Valley Run which is held at Ambey Valley air strip in Loanavla every year.
The biggest drag series event was organized by India Speed Week with three different locations around India. After the series two riders were chosen to represent the country 2017 initiative to bring 11 times world drag racing champion Rickey Gadson to India. The initiative was executed during the Valley Run 2017 event, which gave the participants a platform to perform at the highest level globally. Rickey Gadson, as an extension of the initiative invited two of the top performing drag racers to visit USA to train and get an opportunity to represent India at the World Finals of drag racing held on 16–18 November 2018 in Valdosta GA, USA.[24][25] As a result, the two riders performed in their maiden event outside India. Also during the event, Amit Sharma, the fastest drag racer in Indian drag racing history, produced a time slip of 8.87 sec's – the fastest ever by any Indian.[26]
Drag racing is also gaining popularity in Pakistan, with private organizations sponsoring such events. The Bahria Townhousing project recently organized a drag racing event in Rawalpindi with the help of some of the country's best drivers.[27]
Sri Lanka has seen an immense growth in drag racing due to legal meets held by the Ceylon Motor Sports Club, an FIA sanctioned body. In recent years, exotic cars and Japanese power houses have been taking part in these popular events.[28]
Japan
Drag racing is widely performed in Japan as the racing sport.[citation needed]
South Africa
Drag racing is an established sport in South Africa, with a number of strips around the country including Tarlton International Raceway and ODI Raceway. Drag racing is controlled by Motorsport South Africa and all drivers are required to hold a valid Motorsport South Africa license.[29] Drivers can compete in a number of categories including Top Eliminator, Senior Eliminator, Super Competition Eliminator, Competition Eliminator, Pro Street Bikes, Superbike Eliminator, Supersport Shootout (motorcycle), Street Modified, and Factory Stock.[29]
Drag racing in Russia started in 2004 in Moscow when the Russian Automotive Federation (RAF) sanctioned it as an official motorsport. Drag Racing became popular in Russia after "The Fast and the Furious" film in 2001, but competitions were illegal before 2004. The most outstanding drag racing event of the early years was "DRAG BITVA" (Drag Battle) which took place in Krasnoyarsk, Siberia from 2005 to 2008. Krasnoyarsk is located in the middle of Russia, so it was the best place to bring all the fastest cars from all over the country. Due to the financial situation "DRAG BITVA" was canceled in 2009 and never came back. It was difficult times for drag racing in Russia from 2009 to 2014, but it was supported by enthusiasts in every region. There were a lot of competitions but it was not as big as "DRAG BITVA". In 2014 Dragtimes company in partnership with SMP Racing became the Russian Drag Racing Championship (SMP RDRC) promoters, since then Drag Racing in Russia became more professional. From the very beginning to 2014 only streetcars were allowed to compete in Russia. Now it's also allowed to run promods and dragsters in SMP RDRC. Thanks to the efforts of SMP RDRC promoters in 2019 the first professional dragstrip in Russia "RDRC Racepark" was built. It's located near Moscow in 40 kilometers of downtown at the former airfield Bykovo. It gave many opportunities to test the cars and make new records. Before the track was built, competitions took place on straight parts of circuits, so it was not allowed to prepare the whole 1/4 mile, only 1/8 and the tracks were available for drag racers except racing weekends of local or national events. From the very beginning one of the main ideas of the promoters was to increase the quality and reach of live broadcasts, so SMP RDRC became the first racing series with its video production and remains so to this day.
Russian Championship has four classes:
Pro ET (Bracket class) – most of the participants here are running streetcars (e. g. BMW M5, Audi RS6, Porsche 911, Nissan GT-R, Lamborghini Huracan, etc.). It's allowed to run the car without a roll cage. Breakout for the class is 9.6 sec.
Street – full-body streetcars. Roll cage and all FIA or SFI safety equipment is mandatory. The class includes a lot of different cars (e. g. Toyota Supra, Audi TT RS, Jeep Grand Cherokee SRT-8, Honda Civic, Porsche 911 Turbo S, VAZ 2110, etc.). Breakout for the class is 8.6 sec.
Pro Street – full-body streetcars and 3/4 chassis cars. Breakout for the class is 7.6 sec.
SuperPro Street – door slammers, promods, dragsters, 3/4 chassis cars. The only limitation in the class is breakout which is 6.8 sec.
Regional Series also have four classes divided by ET:
Stock – Breakout 11.9 sec.
Super Stock – Breakout 10.9 sec.
Super Gas – Breakout 9.9 sec.
Super Comp – Breakout 8.9 sec.
The national record belongs to 4-time national champion Dmitry Samorukov: 6.325 seconds at 328.76km/h (204.28mph). It was set in a special record run in 2016 on Dodge Viper Doorslammer in Grozny, Chechen Republic at "Fort Grozny" racetrack.
Dmitry Samorukov was the first Russian participant of the FIA European Championship on a newly built Chevrolet Camaro in the most competitive Promod class in 2019. After six stages of the competition, he took 10th of 38 places overall.
Russian driver Dmitry Kapustin on Nissan Skyline GT-R R32 is holding the European record of AWD streetcars: 7.182 seconds at 312.77km/h (194.35mph). The record was set in a qualifying run in Grozny, Chechen Republic at "Fort Grozny" racetrack in 2018.
1/2 mile races are also popular in Russia. "Unlim 500+" is the main 1/2 mile race in Russia. It's a supercar and sportscar festival where only 500+ hp cars are allowed (e. g. Nissan GT-R, McLaren 720S, Lamborghini Aventador, Porsche 911, Ferrari 488, etc.). The national record on 1/2 mile distance also belongs to Dmitry Samorukov on Nissan GT-R R 35: 13.305 seconds at 346.48km/h (215.29mph). The record was set on a test and tune day at the "RDRC Racepark" track in 2020.
Classes
Caterpillar-sponsored dragster. Note wide slicks and high-mounted wing, to assist traction.
There are hundreds of classes in drag racing, each with different requirements and restrictions on things such as weight, engine size, body style, modifications, and many others. NHRA and IHRA share some of these classes, but many are solely used by one sanctioning body or the other. The NHRA boasts over 200 classes, while the IHRA has fewer. Some IHRA classes have multiple sub-classes in them to differentiate by engine components and other features. There is even a class for aspiring youngsters, Junior Dragster, which typically uses an eighth-mile track, also favored by VW racers.
In 1997, the FIA (cars) and UEM (bikes) began sanctioning drag racing in Europe with a fully established European Drag Racing Championship, in cooperation (and rules compliance) with NHRA. The major European drag strips include Santa Pod Raceway in Podington, England; Alastaro Circuit, Finland; Mantorp Park, Sweden; Gardermoen Raceway, Norway and the Hockenheimring in Germany.
Pain Killer J/D. Note the driver, helmet off, is still in the car, which is under tow on the return road, headed for the pits.
There is a somewhat arbitrary definition of what constitutes a "professional" class. The NHRA includes 5 pro classes; Top Fuel, Funny Car, Pro Stock, Pro Modified and Pro Stock Motorcycle. The FIA features a different set of 5 pro classes; Top Fuel, Top Methanol Dragster, Top Methanol Funny Car, Pro Modified and Pro Stock. Other sanctioning bodies have similarly different definitions. A partial list of classes includes:
Top Fuel dragsters
Top Fuel Dragster (TF/D). The dragsters, or "diggers", are the fastest class. Among the fastest-accelerating machines in the world, these cars can cover the dragstrip in less than 3.7 seconds and record trap speeds over 330mph (530km/h). Under current rules, Modern Top Fuel dragsters are 25ft (7.6m) long and weigh 2,320lb (1,050kg) in race-ready trim. Methanol mixed with up to 90% nitromethane is used as fuel.
Typical Funny Cars
Top Fuel Funny Car (TF/FC). Similar to their dragster counterparts but with a shorter wheelbase and a carbon-fiber body that loosely resembles a production automobile, Funny Cars, or "floppers", routinely run in the 4.0s and can exceed 315mph. In 2017, NHRA driver Robert Hight ran a career-best ET of 3.793 and speed of 339.87mph.
A typical Pro Stock car.
Pro Stock (NHRA, IHRA/MMPSA). Often called "factory hot rods" because of their resemblance to production-based cars (and because they must maintain a relatively stock appearance), and commonly known as "doorslammers", Pro Stockers can record quarter-mile times in the 6.4 second range, and speeds over 210mph (340km/h). They can rev to more than 10,500 rpm and make in excess of 1,300hp (970kW). NHRA engines can be no more than 500-cubic-inch (8.2L)displacement while MMPSA cars can run a maximum of 820 cubic inches (13.4L) (called "Mountain Motors"). IHRA engines can be no more than 400-cubic-inch (6.6L). Both classes require the motors to be naturally aspirated.
Pro Stock Motorcycle (NHRA and IHRA). These highly modified vehicles, which can run under 6.8 seconds at more than 195mph, feature a purpose-built tube chassis and a lightweight, aerodynamically enhanced replica of original bodywork.
Pro Modified (Pro Mod). Known as Top Doorslammer in Australia. Some engine restrictions, very high power. Cars can run superchargers, turbochargers, or nitrous oxide. Cars running blowers are limited to 527 cubic inches (8.6L) while cars with nitrous can run up to 740 cubic inches (12.1L). This class is globally recognised, although the name differs between North America and Australia.
Top Alcohol Dragster (TA/D). Known as Top Methanol Dragster in FIA competition. Top Alcohol Dragsters resemble Top Fuelers, but have significant differences. They may use a supercharged methanol-burning engine or an injected nitromethane combination. They can run in the 5.1s at more than 280mph.
Top Alcohol Funny Car (TA/FC). Known as Top Methanol Funny Car in FIA competition. Similar in physical appearance to their nitro-burning Funny Car counterparts, Top Alcohol Funny Cars are restricted to the use of methanol fuel and have three-speed transmissions. They can run in the 5.4s at more than 265mph. In the IHRA, Alcohol Funny Car is the fifth pro category, replacing NHRA's Pro Stock Bike.
A typical Comp car.
Competition Eliminator. This is the NHRA class with the most variety. Each of its 88 sections is assigned an index based on what a well-built car should run, and races are handicapped according to those indexes.
Sport Front-Wheel-Drive (SFWD). This is a class that is dedicated to solely front wheel drive vehicles. One of the motivations behind the creation of this class was to keep cars as original looking as they could possibly be. SFWD is one of the most common and popular import drag racing classes. The two most common vehicles in this class are the Honda Civic and the Acura Integra. In this class, the number one restriction is that each vehicle must retain its original chassis. No modification to the OEM floorboard or Firewall is permitted. In addition, at least one headlight and both brake lights must be fully functional. Suspension and brake modifications are allowed to a certain extent. Aftermarket components are permitted as long as the original mounting points are not modified. All four brakes must be retained and parachutes are permitted. The stock dashboard and windshield must be retained along with the car's original interior from the front seats forward, while rear seats as well as passenger-side seat may be removed. Racing gas or E85 may be used; methanol may not. Internal engine modifications of all types, aftermarket engine blocks, and engine swaps are permitted. Engines may use nitrous oxide or be turbocharged. Tires may be a maximum of 25in (640mm) tall and 9.5in (240mm) in tread width. All cars must meet a minimum weight requirement of 2,200lb (1,000kg), plus any weight penalties teams may incur for having certain equipment installed that would have given them too much of an advantage over the competition.[30][31][32]
Stick Shift. Reserved for vehicles with a manual transmission. The rising popularity of automatic transmissions in drag racing created the demand for these classes. Popular sanctioning bodies include United Manual Transmission Racers, Pro Stick Racing, Rocky Mountain Stick Shifters, and Ozark Mountain Super Shifters.
Super Comp/Quick Rod. The quickest of the heads-up Super classes (8.90 index) is composed primarily of dragsters. Most cars are capable of running well under the index but use electronic aids to run close to it without breaking out.
Super Gas Probe.
Super Gas/Super Rod. Super Gas entries, which run on a 9.90 index, are primarily full-bodied cars and street roadsters. No dragsters or altereds are permitted. As in Super Comp, competitors use electronic aids to run as close to the class standard without going under.
Super Street/Hot Rod. Racers compete on a fixed 10.90 index. All vehicles must be full-bodied cars and weigh no less than 2,800 pounds except for six-cylinder cars (2,000) and four-cylinder and rotary-powered cars (1,200). Engine and chassis modifications are virtually unlimited.
Super Street MustangA typical Super Stock car
Super Stock. Super Stock vehicles resemble ordinary passenger cars, but are actually heavily modified. Entries are classified using factory shipping weight and horsepower and compete on indexes. The breakout rule is enforced.
Stock. Stock cars are similar to Super Stockers, but rules regarding everything from engine modifications to body alterations are much stricter. Virtually any car is eligible to compete, and entries are classified using factory shipping weight and horsepower.
Top Sportsman (NHRA, IHRA, ANDRA). Competitors in these full-bodied entries may choose their own dial-in for eliminations, generally from 6.00 to 7.99 seconds. Full Tree starts are used, and the breakout rule is enforced. Cars can run in the sixes at more than 200mph (320km/h).
Blown Top Dragster
Top Dragster (T/D) (NHRA, IHRA, ANDRA). Competitors in these open-wheel entries may choose their own dial-in for eliminations, generally from 6.00 to 7.70 seconds. Full tree starts are used, and the breakout rule is enforced. Cars can run in the sixes at more than 200mph (320km/h). Cars can run any combination of motor: blown, turbo, nitrous or just all motor.
Top Fuel Funny Bike (high performance 5 second bikes)
NHRA and ANDRA Summit Racing series Super Pro, Pro, and bike.
Junior Dragster (racers between the ages of 8 and 18 may race a half scale version of the sport's fastest car, Top Fuel Dragster. Juniors run as follows: 12.90-slower for 8-9year olds, 10-12year olds at 8.90, and 13-18year olds 7.90 and slower at a top speed of 85mph). These cars race at 1/8 mile or 1/16 mile.
NHRA new class for Juniors is JR COMP running 6.90s at a top speed of 110 miles per hour (180km/h) (1/8 mile or 1/16 mile).
A complete listing of all classes can be found on the respective NHRA and IHRA official websites.
Dragster engine with dual-plug heads, dual ignition magnetos, and intake snorkel
The UEM also has a different structure of professional categories with Top Fuel Bike, Super Twin Top Fuel Bike, and Pro Stock Bike contested, leaving the entire European series with a total of 8 professional categories.
To allow different cars to compete against each other, some competitions are raced on a handicap basis, with faster cars delayed on the starting line enough to theoretically even things up with the slower car. This may be based on rule differences between the cars in stock, super stock, and modified classes, or on a competitor's chosen "dial-in" in bracket racing.
A 'dial-in' is a time the driver estimates it will take their car to cross the finish line, and is generally displayed on one or more windows so the starter can adjust the starting lights on the tree accordingly. The slower car will then get a head start equal to the difference in the two dial-ins, so if both cars perform perfectly, they would cross the finish line dead even. If either car goes faster than its dial-in (called breaking out), it is disqualified regardless of who has the lower elapsed time; if both cars break out, the one who breaks out by the smallest amount wins. However, if a driver had jump-started (red light) or crossed a boundary line, both violations override any break out (except in some classes with an absolute break out rule such as Junior classes).
The effect of the bracket racing rules is to place a premium on consistency of performance of the driver and car rather than on raw speed, in that victory goes to the driver able to precisely predict elapsed time, whether it is fast or slow. This in turn makes victory much less dependent on budget, and more dependent on skill, making it popular with casual weekend racers.

Historic cars
Smokin' White Owl, built by "Ollie" Morris in 1954
1979 — Vanishing Point, rocket-powered funny car built by Sammy Miller, set current standing world record for fastest quarter-mile time (3.58 seconds) in 1984.[39]

Beam – electronic device (e.g. an optical beam) at the starting line to detect a car's staging position
Big tire – Car with a set of rear tires taller than 28.5 inches tall and or wider than 12.5 inches of tread. Car may have modifications to the rear frame rails and suspension system to allow the large tires to fit under the car. Compare Small tire.
Bottle – nitrous system; also known as the jug.[40][41]
Blanket – a ballistic cover, typically over the supercharged intake manifold assembly to contain shrapnel, in the case of an explosion.
Blow – see Blown.
Blower – supercharger (occasionally turbocharger); in '90s, generally grouped as "power adder" with turbocharger and nitrous
Blown – supercharged, when describing a functioning engine; wrecked, when describing an engine failure.
Blowover – flipping of a car, due to air under car lifting front wheels
Breakout – in bracket racing, running quicker than dial-in; also "breaking out".
Bump – (also called on the bump or in the bubble) a driver is ranked by qualifying order if they are ranked 15 or 16 in most skill classes they are placed "on the bump" if the next driver improves and gets a better score that driver is eliminated and has to do another run to requalify. If they mess up on all qualification days, do not make it to elimination, or lose the first or second round that driver is eliminated and "placed on the trailer" and sent home.[42]
Burnout – intentionally spinning and smoking the tires to build heat for better traction
Christmas tree (or "tree") – device at the starting line containing signal lights, used to start a race in addition to showing starting violations
DA – density altitude; a reference to qualities in the air.
Dial-in (bracket racing) – a car's pre-estimated ET for a pass, used for handicapping the start
Diaper – an absorbent containment blanket under the engine to prevent/reduce oil contact with the track, in the event of parts breakage
Dope (Southern U.S.) – nitrous or propane injection in a diesel engine[citation needed]
Digger – dragster (as distinct from a bodied car or flopper)[44]
ET – Elapsed time. Time from a car leaving the starting line to crossing the finish line.
First or worst[45] – if both drivers commit a foul, the driver who commits the foul first loses, unless it is two separate fouls, where the loser is the driver who committed the worse foul (lane violation is worse than foul start, and failure to participate in a post-run inspection is worst).
Flopper
commonly, Funny Car
any flip-top car[46] Coined by dragster crews in the late 1960s to separate Funny Cars, which had fiberglass bodies with fenders, from dragsters.

Holeshot win – a race won by a driver with a slower elapsed time but a faster reaction time.
Hook[ed] up – good traction between tires and track resulting in increased acceleration and reduced slipping or smoking of tires.
James Bond – when a driver's reaction time is seven thousandths of a second after the green light (.007). A "James Bond Red" is a reaction time of -.007 seconds (red light), which is disqualification unless the opponent commits a more serious violation.[47]

Put on the trailer – lost (got "put on the trailer") or won (put the other driver on the trailer)
Quad - when a drag racing event features four cars in a single race, each race is called a Quad.
Quick 8 (Q8) – quickest eight cars in a defined race
Rail – dragster (as distinct from bodied car or flopper). From the exposed frame rails of early cars.
Redlight(ed) – jump(ed) the start, left before tree turned green. This is a loss unless the opponent commits a more serious foul (boundary lines or failed inspection).
Sandbagging – releasing the throttle or using the brakes at the end of the track during a bracket race after dialing a purposely slow time. Considered a dirty trick or tantamount to cheating in amateur classes.

The National Hot Rod Association (NHRA) is a governing body which sets rules in drag racing and hosts events all over the United States and Canada. With over 40,000 drivers in its rosters, the NHRA claims to be the largest motorsport sanctioning body in the world.
Funny Car is a type of drag racing vehicle and a specific racing class in organized drag racing. Funny cars are characterized by having tilt-up fiberglass or carbon fiber automotive bodies over a custom-fabricated chassis, giving them an appearance vaguely approximating manufacturers' showroom models. They also have the engine placed in front of the driver, as opposed to dragsters, which place it behind the driver.
Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 341.68 miles per hour (549.9 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.61 seconds.
A dragstrip is a facility for conducting automobile and motorcycle acceleration events such as drag racing. Although a quarter mile is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.
The International Hot Rod Association (IHRA) is the second-largest drag racing sanctioning body after the National Hot Rod Association (NHRA).
Pro stock is a class of drag racing featuring "factory hot rods". The class is often described as "all motor", due to the cars not using any form of forced induction such as turbocharging or supercharging, or other enhancements, like nitrous oxide, along with regulations governing the modifications allowed to the engines and the types of bodies used.
The Junior Dragster or Jr Dragster is a scaled-down version of the top fuel dragster. The cars were developed in New Zealand in 1988, with classes developed by the New Zealand Hot Rod Association. The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL. The JDRL is a division of the NHRA, which consists of two different dragster classes, traditional Jr. Dragster having a wheelbase between 90 and 150 inches and a single-cylinder, five brake horsepower Briggs & Stratton engine, and the larger Jr. Comp dragster being 150-190 inches in wheelbase and using a motorcycle or personal watercraft engine. Junior drag racers may choose to participate in programs run by the NHRA, IHRA and the Australian National Drag Racing Association [ANDRA], or at an unsanctioned facility. Drivers may be male or female and must be at least five years of age to test, and six years to compete, and be no older than 20 years on December 31 of the competition year.
Top Alcohol refers to two different classes in professional drag racing: Top Alcohol Dragster and the Top Alcohol Funny Car. Commonly known as "alky" cars, both are akin in design to the premier Top Fuel classes, but less powerful. In both classes, the cars are either supercharged ("blown") engines, burning alcohol (methanol) or can burn nitromethane and be normally aspirated, fuel injected engines. Top Alcohol Dragsters and Funny Cars resemble their nitromethane (Fuel) counterparts, with about half the power of their respective classes. Each car uses a three-speed transmission.
Nostalgia drag racing is a form of drag racing that uses cars from earlier eras of drag racing, as well as cars built to fit the guidelines of earlier eras using parts that would have been available in that era.
Pro Modified, also known as Pro Mod, is a class or division in the sport of drag racing used in the NHRA and FIA (quarter-mile) and the Professional Drag Racers Association (PDRA) (eighth-mile). It is similar to the Top Doorslammer class as defined by the ANDRA.
Eddie Hill is an American retired drag racer who won numerous drag racing championships on land and water. Hill had the first run in the four second range (4.990 seconds), which earned him the nickname "Four Father of Drag Racing." His other nicknames include "The Thrill", "Holeshot Hill", and "Fast Eddie". In 1960, he set the NHRA record for the largest improvement in the elapsed time (e.t.) when he drove the quarter mile in 8.84 seconds to break the previous 9.40-second record.
Jack Chrisman was an American drag racer. He was a drag racing pioneer and 1961 champion. He was influential in the formation of the Funny Car class, as he introduced the first blown injected nitro-burning Funny Car. The National Hot Rod Association (NHRA) ranked Chrisman 23rd on their Top 50 drivers in 2001.
Don Nicholson was an American drag racer from Missouri. He raced in the 1960s and 1970s when there were few national events. The National Hot Rod Association (NHRA) estimates he won 90 percent of his match races. As of 2002, he held the record for the most number of categories in which he reached a final round : Funny Car, Pro Stock, Super Stock, Competition Eliminator, Stock, and Street. He was nicknamed "Dyno Don" after he was one of the first drivers to use a chassis dynamometer on his cars in the late 1950s, a skill that he learned while working as a line mechanic at a Chevrolet car dealer.
Bruce Larson (1937) is an American retired drag racer from Camp Hill, Pennsylvania. He became nationally known for his match races. He quit funny Car racing in 1972 after a bad fire and raced in the Pro Stock class for 2 years. He then returned to the Funny Car class and match racing until 1987 where he fought his way to the NHRA Funny Car Championship in 1989. He led the points chase from start to finish collecting 6 National Event wins, 5 runner ups and the Car Craft Funny Car Driver of the Year award. That championship car is now one of only 2 drag race cars in the collection of the Smithsonian Institution, the other being Don Garlits' rear engine dragster. He was inducted into the International Drag Racing Hall of Fame in 2006. Larson is remembered for his red, white, and blue USA-1 Chevrolet Camaros.
Dale Armstrong was a Canadian drag racer and crew chief. After winning 12 National Hot Rod Association (NHRA) and 12 International Hot Rod Association (IHRA) events in the 1970s, including the Pro Comp title in 1975, he became Kenny Bernstein's crew chief. The combination produced four consecutive national championships in Funny Car and another in Top Fuel. Bernstein became the first driver to top the 300 miles per hour mark in an engine tuned by Armstrong. Armstrong has been inducted in numerous halls of fame. He died on November 28, 2014, at his home in Temecula, California, at the age of 73. He had sarcoidosis.
Summit Racing Equipment is an automotive parts retailer with four retail stores and distribution centers located in Tallmadge, Ohio; Sparks, Nevada; McDonough, Georgia; and Arlington, Texas. Summit Racing Equipment is also involved in motorsports and other events as a sponsor.
The NHRA Mission Foods Drag Racing Series is a drag racing series organized by the National Hot Rod Association (NHRA). It is the top competition series of the NHRA, comprising competition in four classes, including Top Fuel Dragster, Funny Car, Pro Stock, and Pro Stock Motorcycle.
New England Dragway is a 1⁄4 mile NHRA dragway in Epping, New Hampshire, Rockingham County, United States. The track hosts the New England Nationals event as part of the NHRA Mission Foods Drag Racing Series. The track also hosts a regional event as part of the NHRA Lucas Oil Drag Racing Series.
A dragster is a specialized competition automobile used in drag racing.
