Drag racing is a competition in which specially prepared automobiles or motorcycles compete two at a time to be the first to cross a set finish line, from a standing start, in a straight line, over a measured distance, most commonly a ¼-mile (402.3-metre / 1,320 ft) straight track.
The race track, known as a dragstrip, uses an electronic timing system to determine the winner.
RuPaul's Drag Race is an American reality television series produced by World of Wonder for Logo. RuPaul plays host, mentor and inspiration for this series, which details RuPaul's search for "America's next drag superstar."[1]
The show was greenlit in May 2008, according to a press release by MTV Networks. It premiered in the U.S. on February 2, 2009 on Logo. It premiered in Canada on the MuchMore network on Sunday, February 15, 2009.[2] The show also airs at 9:00 p.m. Eastern Time on the VH1 network[3], but due to contractual obligations with Logo, this is not being promoted.[citation needed]
The show was marked as the most watched series on Logo in its first season, and it became the most streamed series ever on LogoTV.com during its second.[4] The title of the show is a play on drag queen and drag racing, with the title sequence and theme song "Covergirl (Put the Bass in Your Walk)" both having a drag racing theme. Both the contestants and fans are affectionately referred to as "Racers."
The series was renewed for a fourth season on April 18, 2011, along with its companion series Untucked; both are scheduled to be broadcast in January 2012.[5Before each race (also 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. Each driver then lines up (or stages) at the starting line. Races are started electronically by a system known as a Christmas tree. The Christmas tree consists of a column of lights for each driver/lane. In each column, the top two lights are small amber lights (or two halves of an open blue circle split with a bar in the center that lights when the second light has turned on; that form debuted April 15, 2011 at zMax Dragway and became permanent for NHRA National events) [1] connected to light beams on the track, which when broken by the vehicle's front tire(s) indicate that the driver has pre-staged (approximately 7 inches (180 mm) from the starting line) and then staged (at the starting line).[2]

Below the staging lights are three large amber lights, a green light, and a red light. When both drivers are staged, the tree is activated to start the race, which causes the three large amber lights to illuminate, followed by the green light. There are two standard light sequences: either the three amber lights flash simultaneously, followed 0.4 seconds later by the green light (a Pro tree), or the ambers light in sequence from top to bottom, 0.5 seconds apart, followed 0.5 seconds later by the green light (a Sportsman tree, or full tree). If the front tires leaves from a stage beam (stage and pre-stage lights both turned off) before the green light illuminates, the red light for that driver's lane illuminates instead, indicating disqualification (unless a more serious violation occurs). Once a driver commits a red-light foul (also known as redlighting), the other driver can also commit a foul start by leaving the line too early but still win, having left later. Should both drivers leave after the green light illuminates, the one leaving first is said to have a holeshot advantage.
The winner is the first vehicle to cross the finish line (and therefore the driver with the lowest total reaction time and elapsed time). The elapsed time is a measure of performance only; it does not necessarily determine the winner. Because elapsed time does not include reaction time and each lane is timed individually, a car with a slower elapsed time can actually win if that driver's holeshot advantage exceeds the elapsed time difference. This is known as a holeshot win.[3]
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 starting line. 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 (20 m) to the finish line, indicating the approximate maximum speed of the vehicle during the run.
In the standard racing format, the losing car and driver are removed from the contest, while the winner goes on to race other winners, until only one is left.

[edit] North America

The National Hot Rod Association (NHRA) oversees the majority of drag racing events in North America. The next largest organization, Feld Entertainment's International Hot Rod Association (IHRA), is about one-third the size of NHRA. Nearly all drag strips are associated with one sanctioning body or the other. The NHRA is more popular with large, 1/4-mile (402.3-metre / 1,320 ft) nationally recognized tracks (although the two fuel classes have 304.8-metre (1,000 ft) races to reduce top speeds due to safety concerns), while the IHRA is a favorite of smaller 1/8-mile [201.2-metre (660 ft)] local tracks (and offers selected races on their national tour under the 1/8-mile format). One reason for this (among others) is the IHRA is less restrictive in its rules, such as rules on nitrous oxide (legal in Pro Modified) and oversized engines (no 500-cubic-inch (8.2 L) restriction in the IHRA's Pro Stock category) and less expensive to be associated.
Prior to the founding of the NHRA and IHRA, smaller organizations sanctioned drag racing in the early years. The first commercially sanctioned drag race on the East Coast was reputed to have been held at Longview Speedway (now Old Dominion Speedway) in Manassas, Virginia. Old Dominion Speedway is currently sanctioned by the SBRA (Southern Bracket Racing Association).
In the midwest, there are several small organizations that have been active in drag racing for several years. One that is notable and well established is Nostalgia Pro Comp Association. They feature old school dragsters and muscle cars, under numerous classes to choose from. The majority of the tracks they race are 1/8-mile and 1/4-mile.
Drag racing is permitted on Main Street in Worcester, Massachusetts during the New England Summer Nationals.

[edit] United Kingdom

The British Hot Rod Association (BHRA) was established in 1960, with the intent of unifying local clubs and holding organised Drag Races at disused airfields like Duxford and Graveley.[4]

[edit] 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".[5] ANDRA sanctions races throughout Australia and throughout the year at all levels, from Junior Dragster to Top Fuel.
The Australian sport adds the Top Doorslammer class, which caters for full-bodied racing sedans, which are replicas of production vehicles. Engines for this class of racing are large-capacity, supercharged V8 engines, running methanol.

[edit] Europe

Drag racing was imported to Europe by American NATO troops during the Cold War.[6] Races were held in West Germany beginning in the 1960s at the airbases at Ramstein and Sembach.[7]

[edit] South America

Organized drag racing in Colombia is Club G3's responsibility, which is a private organization. The events take part at Autódromo de Tocancipá.

[edit] South Asia

Organized drag racing is rapidly growing in India. Autocar India organised the country's first drag race meet in Mumbai in 2002.[8]
Drag racing is also gaining popularity in Pakistan, with private organizations organizing such events. The Bahria Town housing project recently organized a drag racing event in Rawalpindi, with the help of some of the country's best drivers.[9]

[edit] 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.[10] 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.[10]

[edit] Classes

There are literally 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, 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. The major difference is the nitro-class distance, which is 300 meters at some tracks, although the NHRA and FIA are likely to discuss the distance change in the future.

There are currently only 5 pro classes in North America, which are:
  • Top Fuel Dragster (TF/D). The rail dragsters, or "diggers", the fastest class—up to 90% nitromethane fuel is used.
  • Top Fuel Funny Car (TF/FC) Nearly as fast as the diggers, the "floppers" (marginally) resemble actual cars.
  • Pro Modified (Pro Mod) Some engine restrictions, very high power. Cars can run superchargers, turbochargers, or nitrous oxide. Cars running blowers are limited to 527-cubic-inch (8.64 L) while cars with nitrous can run up to 740 cubic inches (12.1 L).
  • Pro Stock (NHRA, MMPSA) "Doorslammers" must maintain a relatively stock appearance. NHRA engines can be no more than 500-cubic-inch (8.2 L) displacement while MMPSA cars can run a maximum of 820 cubic inches (13.4 L) (called "Mountain Motors"). Both classes require the motors to be naturally aspirated.
  • Pro Stock Bike (NHRA and ANDRA) Heavily modified motorcycles.
In addition to the professional classes, these are some other popular classes:
  • Top Alcohol Dragster (TA/D)
  • Top Alcohol Funny Car (TA/FC). In the IHRA, Alcohol Funny Car is the fifh pro category, replacing NHRA's Pro Stock Bike.
  • Competition Eliminator
  • Outlaw Series NHRA engine 2800 pound car where they used Alchool or +- 116 octane gaz
  • Pro FWD
  • Super Comp/Quick Rod
  • Super Gas/Super Rod
  • Super Street/Hot Rod
  • Super Stock
  • Stock
  • Sport Compact
  • Top Sportsman (NHRA and IHRA)
  • Top Dragster (NHRA and IHRA) In NHRA, these two classes are sometimes run together as Top Comp
  • Top Fuel Funny Bike (high performance 5 second bikes)
  • NHRA and ANDRASummit 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 following: 12.90-slower for 8-9 year olds, 10-12 year olds at 8.90, and 13-18 year olds 7.90 and slower at a top speed of 85 mph). 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 (180 km/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 (see external links).

In the FIA European Drag Racing Championships, a different structure of professional categories is used with Top Fuel Dragster (with a 90% nitromethane mix), Top Methanol (Alcohol) Dragster, Top Methanol (Alcohol) Funny Car, Pro Stock, and Pro Modified running as professional championships as well as FIA specifications published for Fuel Funny Car although this does not run as a championship.
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 start 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 his or her 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). This eliminates any advantage from putting a slower time on the windshield to get a head start. 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 large infusions of money, and more dependent on skill. Therefore, bracket racing is popular with casual weekend racers. Many of these recreational racers will drive their vehicles to the track, race them, and then simply drive them home. Most tracks do not host national events every week, and on the interim weekends host local casual and weekend racers. Organizationally, however, the tracks are run according to the rules of either the NHRA or the IHRA (for the most part). Even street vehicles must pass a safety inspection prior to being allowed to race.
Besides NHRA and IHRA, there are niche organizations for muscle cars and nostalgia vehicles. 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 1/8 mile races. The current electric drag racing record is 7.824s for a quarter mile. Another niche organisation is the VWDRC which run a VW-only championship with vehicles running under 7 seconds.
Rules require a radiator overflow tank, commonly called a puke can. This type (using an old beer can) is illegal at many tracks where a factory-type stock overflow tank (usually plastic) is required.
