111-592: The Northeastern Midget Association ( NEMA ) is a sanctioning body of short track auto racing in the United States and is the oldest sanctioning body of midget car type open wheel racing in North America. On March 8, 1953, a meeting was held at the Thompson Speedway Clubhouse for the purpose of forming a new midget racing organization. The founders were dedicated racing men determined to salvage

222-403: A " roval " (a blend word combining "road course" and "oval") is an oval track racing facility that features a road course in the infield (and/or outfield), that is usually linked to the oval circuit. This type of course makes for a multi-purpose track, and allows the facility to be used for both oval and road racing. A typical combined road course consists of the oval portion of the track, using

333-510: A 1/8 mile version. Perhaps the most unusual concentric oval facility is Dover Speedway- Dover Downs . The one-mile oval track encompasses a 0.625-mile harness racing track inside. Oval tracks usually have slope in both straight and in curves, but the slope on the straights is less, circuits without any slope are rare to find, low-slope are usually old or small tracks, high gradient are more common in new circuits. Circuits like Milwaukee Mile and Indianapolis Motor Speedway have 9° banking in

444-601: A 500-lap or 400-lap distance. Short tracks in many cases have lights installed and routinely host night races. The short ovals still form the backbone of NASCAR in the feeder series. Three race tracks of this type are also represented in the Cup: Bristol, Martinsville and Richmond. Tracks with potential for future cup races are the Iowa Speedway built in 2006, the Nashville Fairgrounds Speedway used until 1984 in

555-486: A Daytona 500 race, it was still a significant improvement over its predecessor the Dodge Charger 500. NASCAR feared that these increasing speeds significantly surpassed the abilities of the tire technology of the day, and it would undoubtedly increase the number of gruesome wrecks that were occurring. As a result, the 1970 Homologation rules were changed so that one car for every two U.S. dealers had to be built for sale to

666-796: A Midwest regional series. In addition to the ARCA Menards Series , it also sanctions the ARCA Midwest Tour since 2007, and previously the ARCA Lincoln Welders Truck Series from 1999 to 2016. NASCAR purchased ARCA in early 2018. For the 2020 season, the NASCAR K&;N Series East and West were rebranded under the ARCA banner as the ARCA Menards Series East and ARCA Menards Series West . Outside of NASCAR, there are

777-422: A concentric 1/4-mile oval layout. The 1/4-mile layout became a popular venue for legends car racing . The name "legends oval" was derived from this use. They have also seen use with go-karts, short track stock cars, and other lower disciplines. This idea was adopted by numerous tracks including Texas Motor Speedway, Atlanta Motor Speedway, Kentucky Speedway , Las Vegas Motor Speedway , and Iowa Speedway which has

888-618: A cost of A$ 54 million, was modeled on a scaled down version of the famous Charlotte Motor Speedway . Other tracks used included the 1 ⁄ 2 mile (805 metre) Speedway Super Bowl at the Adelaide International Raceway (also owned by Jane, this was the only paved oval track in Australia other than the Thunderdome, though with only 7° banking in the turns it was more of a traditional flat track), as well as road courses such as

999-400: A custom built machine, or a heavily modified streetcar. Individual sanctioning bodies (like NASCAR, ACT , PASS , UARA, ASA , CARS Tour , etc.) maintain their own late model rule books, and even individual racetracks can maintain their own rule books, meaning a late model that is legal in one series or at one track may not be legal at another without modifications. The national touring series,

1110-495: A great deal of available data, and NASCAR was formed just as some of the improved technology was about to become available in production cars. Until the advent of the Trans-Am Series in 1967, NASCAR homologation cars were the closest thing that the public could buy that was actually very similar to the cars that were winning national races. The 1949 Oldsmobile Rocket V-8 with a displacement of 303 cu in (5.0 L)

1221-411: A highly sophisticated purpose built race car with race-tuned V-8 engines developing 480 kW (650 bhp), quick change axles and gearboxes and biased and staggered chassis and braking set up for constant left turning. However large bumpers were mandatory with contact very much encouraged to remove opponents. The sport can be seen at venues throughout Britain and Mainland Europe. A downsized version of

1332-405: A length of one mile or more. Since the introduction of the intermediate oval, Superspeedway is an oval race course of 2 miles or longer. There are six active superspeedways in the United States, the most famous being Indianapolis Motor Speedway and Daytona International Speedway , both 2.5 miles (4.0 km) long. These tracks were built in 1909 and 1959 respectively. Indianapolis Motor Speedway

1443-492: A light rain. Some tracks (e.g., Evergreen Speedway in Monroe, WA) have "rain or shine" rules requiring races to be run in the rain. Safety has also been a point of difference between the two. While a road course usually has abundant run-off areas , gravel traps, and tire barriers, oval tracks usually have a concrete retaining wall separating the track from the fans. Innovations have been made to change this, however. The SAFER barrier

1554-445: A lot of oval tracks, which neither have a classical geometric shape nor still represent a modern tri-oval in the strict sense. While these courses still technically fall under the category of ovals, their unique shape, flat corners, hard braking zones, or increased difficulty, often produces driving characteristics similar to those of a road course. Some facilities feature several ovals track of different sizes, often sharing part of

1665-470: A meeting at the Streamline Hotel in order to form an organization that would unify the rules. When NASCAR was first formed by France in 1948 to regulate stock car racing in the U.S., there was a requirement that any car entered be made entirely of parts available to the general public through automobile dealers. Furthermore, the car models were required to have sold over 500 units to the public. This

1776-449: A notable exception. Many 1-mile dirt ovals were used by stock cars or champ cars before race tracks with dirt surfaces were removed from the racing calendar in the early 1970s. Many of these racetracks got the nickname "Fairgrounds” — for example Arizona State Fairgrounds , California State Fairgrounds and Michigan State Fairgrounds Speedway . The origin of these racetracks was in harness racing , which commonly used 1-mile tracks. Also,

1887-628: A number of other national or regional stock-car sanctioning bodies in the United States. There are a few organizations that cater to these local short tracks . The American Speed Association (ASA), Champion Racing Association (CRA), International Motor Contest Association (IMCA), United Auto Racing Association (UARA), Championship Auto Racing Series (CARS), and they all sanction their own forms of stock-car racing, on varying types of track, and with various levels of media coverage. The International Race of Champions (IROC) and Superstar Racing Experience (SRX) are usually perceived as being outside of

1998-405: A road course, there are many different lines that can work on an oval track. The preferred line depends on many factors including track conditions, car set-up, and traffic. The oval track driver must choose which line to use each time they approach a corner. On a short track in a 25-lap feature race, a driver might not run any two laps with the same line. Both types of racing place physical demands on

2109-579: A row) in the boxier Plymouth Belvedere. The 1969 season featured the Torino Cobra or Torino "Talladega" which had enough aerodynamic body improvements that it gave it a higher speed than the 1968 Torino, with no other changes. The Cobra, featuring extended nose and reshaped rockers, was renamed Talladega part way through the 1969 season when the Boss 429 replaced the 427. Starting in 1963 up till this point, Ford had won six straight Manufacturer Championships, and by

2220-490: A single cam-in-block . But even without the cammer, the Ford FE 427 won in 1965. In 1966 Chrysler sold enough of the 426 Hemis to make it available again, and they put it in their new Dodge Charger which had a low-drag rear window that was radically sloped. It was called a "fast-back", and because of this David Pearson was the series champion that year with Richard Petty dominating 1967, winning 27 of 48 races (including 10 in

2331-417: A single accident. This type of accident is often called " The Big One ". Oval track racing requires different tactics than road racing. While the driver does not have to shift gears nearly as frequently, brake as heavily or as often, or deal with turns of various radii in both directions as in road racing, drivers are still challenged by negotiating the track. Where there is generally one preferred line around

2442-453: A speed record for stock cars in a 2007-season Dodge Charger built to NASCAR specifications by achieving a maximum speed of 244.9 mph (394.1 km/h) at Bonneville Speedway . For the 2015 NASCAR Cup Series , power output of the competing cars ranged from 750 to 800 hp (560 to 600 kW). In the 1920s, moonshine runners during the Prohibition era would often have to outrun

2553-461: A stand-alone road course layout(s) in the infield not directly linked to the oval layout, or otherwise using only a short portion of the oval. Combined road courses combine the high speed characteristics of ovals with the technical precision of road courses . It allows road racing disciplines the unique experience of being held in the stadium style atmosphere of an oval superspeedway. Numerous combined road courses saw widespread use with sports cars in

2664-570: A way that they hoped would make the cars safer and more equal, so the race series would be more a test of the drivers, rather than a test of car technology. In addition, R.J. Reynolds (the tobacco conglomerate) took over as the major sponsor of NASCAR racing (changing the name to the "Winston Cup") and they made a significantly larger financial contribution than previous sponsors. Richard Petty's personal sponsorship with STP also set new, higher standards for financial rewards to driving teams. The sudden infusion of noticeably larger amounts of money changed

2775-467: Is a phenomenon found on fast, high-banked superspeedways. It occurs when the vehicles racing are cornering at their limit of aerodynamic drag , but within their limit of traction . This allows drivers to race around the track constantly at wide open throttle . Since the vehicles are within their limit of traction, drafting through corners will not hinder a vehicle's performance. As cars running together are faster than cars running individually, all cars in

2886-478: Is referred to as " homologation ", which other racing series has since adapted for their own rulesets. In NASCAR's early years, the cars were so "stock" that it was commonplace for the drivers to drive themselves to the competitions in the car that they were going to run in the race. While automobile engine technology had remained fairly stagnant in World War II, advanced aircraft piston engine development had provided

2997-545: Is the Talladega Superspeedway in Talladega, Alabama . Built in 1969, it is 2.66 miles (4.28 kilometers) long, and holds the current record for fastest speed in a stock car, lapping at an average of 216.309 mph (348.116 km/h) and reaching 228 mph (367 km/h) at the end of the backstretch. Daytona and Talladega are the pinnacle of stock car superspeedway racing, where restrictor plates are mandated by

3108-513: Is the predominant form of auto racing in the United States. According to the 2013 National Speedway Directory, the total number of oval tracks, drag strips and road courses in the United States is 1,262, with 901 of those being oval tracks and 683 of those being dirt tracks. Among the most famous oval tracks in North America are the Indianapolis Motor Speedway , Daytona International Speedway and Talladega Superspeedway . Pack racing

3219-597: Is the second tier series in the United States. It serves as the primary feeder series to the Cup Series, similar to Formula Two for Formula One , and Indy Lights for Indy Car . Races are commonly held as a support race to Cup Series events. Many current Cup Series drivers formerly competed in the Series before moving on to competing full-time in the Cup Series. The Xfinity series typically features multiple Cup Series competitors competing alongside full time Xfinity drivers. There

3330-497: Is the team racing format. Typically teams racing consists of two teams of four cars each that work together to win the race. Teams normally protect their "runners" while attempting to eliminate the opposing team, the races can be decided by a points format or first across the finish line. The class most resembling the North American form of stock car racing are known as Saloon cars. Super Saloons are similar to dirt late models with

3441-449: Is very common as vehicles may travel two and three abreast. This forces drivers to use strong mental discipline in negotiating traffic. There are drawbacks, however. Should an accident occur at the front of the pack, the results could block the track in a short amount of time. This leaves drivers at the back of the pack with little time to react and little room to maneuver. The results are often catastrophic as numerous cars may be destroyed in

3552-489: Is widely recognized as the first postwar modern overhead valve (OHV) engine to become available to the public. The Oldsmobile was an immediate success in 1949 and 1950, and all the automobile manufacturers could not help noticing the higher sales of the Oldsmobile 88 to the buying public. The motto of the day became "win on Sunday, sell on Monday." However, in spite of the fact that several competing engines were more advanced,

3663-589: The MotoGP races were run counter-clockwise, with some reconfigured corners to fix corner apex problems. Michigan was also an example of a clockwise combined road course. Another example is the Adelaide International Raceway in Australia which combines a 2.41 km (1.50 mi) road course with an 0.805 km (0.500 mi) speedway bowl. The Bowl forms a permanent part of the road course and also runs clockwise. At many tracks, multiple configurations are available for

3774-533: The 24 Hours of Daytona . Since 2018, NASCAR has held the Bank of America Roval 400 on a combined course at Charlotte . In some rare examples, the combined road course layout is run in the opposite direction to the oval circuit. For instance, at Indianapolis the oval is run counter-clockwise, but the combined road course used during the IndyCar Series Grand Prix of Indianapolis is run clockwise. However

3885-503: The BriSCA Formula 1 Stock Cars , the smaller BriSCA Formula 2 Stock Cars , previously known as "The Juniors" or "Junior Stock Cars", are also very popular. these cars are powered by the 2 litre Ford 'Pinto' engine. There are also many other formulas running on the oval tracks throughout a season that starts around March/Easter and continues to October/November. In the 2008 World Final, held at Ipswich, Andy Smith raced to victory becoming

3996-557: The NASCAR Late Model Sportsman Series , originated from local late model races in the east coast of the U.S. This division was later called the "Busch Series", the "Nationwide Series", and currently the "Xfinity Series" as its title sponsor changed. Late model racing has a very big following throughout the country. Many of the biggest late model races have very large purses, some equivalent to some NASCAR Truck and Xfinity Series races, that attract drivers from all over

4107-651: The Surfers Paradise Street Circuit (where the cars ran as a support category to the Gold Coast IndyCar Grand Prix ), Oran Park in Sydney , and the famous Mount Panorama Circuit . The term 'stock cars' in the UK refers to a specialized form of racing that bears little resemblance to any road car. Stock car racing was brought to Britain in 1954. Taking place on existing greyhound or speedway tracks,

4218-592: The "top 3" series. In addition to the top three series, NASCAR also sanctions many regional and local series. NASCAR also sanctions three international series that race in Canada , Mexico , and Europe . The most prominent championship in stock car racing is the NASCAR Cup Series . It is the most popular racing series in the United States, drawing over 6 million spectators in 1997, an average live audience of over 190,000 people for each race. The most famous event in

4329-424: The 1970s and early 1980s. However, their use at the professional level has since diminished considerably, since most layouts lacked the desirable topography and competitive challenges of natural road courses. In addition, most combined road course circuits offer poor sightlines for fans sitting in the grandstands. Oftentimes the challenging infield portion is obscured or not visible at all from the grandstands that line

4440-824: The 2000s were of this type. These include the Chicago Motor Speedway and the Walt Disney World Speedway , which were built during the 1990s construction boom but used for only four years. The historic Nazareth Speedway , which was paved in 1986, was completely abandoned after the 2004 season. Physically, many mile oval still exist such as the Rockingham Speedway and the Pikes Peak International Raceway . However, these racetracks have not been used by nationally important motorsports events for years. There are only three 1-mile tracks left on

4551-409: The 2008 BriSCA F1 Stock Car World Champion for the second time in his career, taking the crown from brother Stuart Smith Jnr. 2009 also saw Andy Smith win again this time at Kings Lynns Norfolk Arena. 2010 saw Andy Smith win for a 3rd consecutive time at Coventry, the same venue as his 1st win in 2006. The 2011 World Championship took place at Northampton on September 10 with 2 Paul Harrison the winner of

4662-664: The Cup, and the Memphis Motorsports Park, which had races of the Busch Series back then until the 2000s. The Auto Club Speedway is to be converted from a 2-mile super speedway to a 1/2 mile short track in 2024. Synonymous with the name, a 1-mile (1.61 km) oval is a popular and common length for oval track racing. The exact measurements, however, can vary by as much as a tenth of a mile and still fall into this category. Most mile ovals are relatively flat-banked, with Dover being

4773-703: The Ford Falcon and Chevy II engines take their share of wins over the mighty “Offy”. NEMA remains one of the main short track sanctioning bodies in the country and one of the largest in the northeastern US. With 10-15 races a year, the series runs at some of the most historic tracks in America, and when top the feature event, NEMA midgets support some of the top series such as; ISMA and the NASCAR Whelen Modified Tour . NEMA also sanction its own junior support series, NEMA Lites. The Lites are similar in appearance to

4884-467: The Ford Talladega, Mercury Spoiler II, Charger 500, Dodge Daytona and Plymouth Superbird to a maximum engine displacement of 305 cu in (5.0 L) for 1971. Almost all teams switched to non-aero bodystyles. NASCAR eventually adopted a restrictor plate to limit top speeds for the 7.0L engine as teams switched to small-block 358 cu in (5.9 L) engines. NASCAR edited the rules in

4995-510: The NASCAR racing calendar: Phoenix, Loudon, and Dover. IndyCar only returned to 1-mile oval racing with the addition of the Milwaukee Mile in 2024 after 9 years of it being off the schedule. Also referred to with the general term of "speedway", these courses are 1 to 2 miles (1.6 to 3.2 km) in length, but the term is particularly reserved for 1.5-mile (2.4 km) tracks. At the beginning of

5106-514: The UK and New Zealand there is a racing formula called stock cars, but the cars are markedly different from any road car. In Australia there was a formula that was quite similar to NASCAR called AUSCAR . The Racecar-Euro Series began in 2009 and was sanctioned by NASCAR as a touring series in 2012, currently operating as the NASCAR Whelen Euro Series . "True" stock car racing, which consists of only street vehicles that can be bought by

5217-597: The United Kingdom, have forms of stock car racing worldwide as well. Top-level races typically range between 200 and 600 miles (322 and 966 km) in length. Top-level stock cars exceed 200 mph (322 km/h) at speedway tracks and on superspeedway tracks such as Daytona International Speedway and Talladega Superspeedway . Contemporary NASCAR-spec top-level cars produce maximum power outputs of 860–900 hp from their naturally aspirated V8 engines. In October 2007 American race car driver Russ Wicks set

5328-469: The United States after World War II, this type of racing was early-on characterized by its participants' modification of passenger cars in pursuit of higher speeds, hence the name. In many regions, particularly on the east coast, modified racing is considered the highest class of stock cars in local racing. NASCAR officially sanctions the NASCAR Whelen Modified Tour which is the oldest racing series sanctioned by NASCAR. The SMART Modified Tour , at one point

5439-418: The aerodynamic and low-slung Hudson Hornet managed to win in 1951, 1952, and 1953 with a 308 cu in (5.0 L) inline six-cylinder that used an old-style flathead engine , proving there was more to winning than just a more powerful engine. At the time, it typically took three years for a new design of car body or engine to end up in production and be available for NASCAR racing. Most cars sold to

5550-469: The authorities. To do so, they had to upgrade their vehicles—while leaving them looking ordinary, so as not to attract attention. Eventually, runners started getting together with fellow runners and making runs together. They would challenge one another and eventually progressed to organized events in the early 1930s. The main problem racing faced was the lack of a unified set of rules among the different tracks. When Bill France Sr. saw this problem, he set up

5661-408: The back straight of the oval. As they are separate tracks, this creates a unique situation where different races can actually be run on both the oval and the full road course at the same time. Also unique is that unlike most combined circuits which use the oval track's start/finish line and pits, in the case of Calder Park it is the road course start/finish line and pits that are used. This configuration

5772-514: The cars coming towards and moving away from their vantage point. Traditional ovals (such as Indianapolis ) offered only limited linear views of the course, and required fans to look back and forth much like a tennis match. The tri-oval shape prevents fans from having to "lean" to see oncoming cars, and creates more forward sight lines. The modern tri-ovals were often called as cookie cutters because of their (nearly) identical shape and identical kind of races. Additional prominent examples: There are

5883-526: The cars conform to standard model specs has changed over the years and varies from country to country. Today most American stock cars may superficially resemble standard American family sedans but are in fact silhouette cars: purpose-built racing machines built to a strict set of regulations governing the car design ensuring that the chassis , suspension , engine, etc. are architecturally identical to those in stock production vehicles. For example, NASCAR Cup Series race vehicles now require fuel injection . In

5994-475: The cars were mostly 'stock' cars from the 1930s with locked rear axle differentials and added armour. After the first couple of years 'specials' began to appear eventually making the 'stock' car name something of a misnomer. Since the early days of stock car racing in Britain the sport has developed into many different classes, from the destructive 'Banger' categories to the very sophisticated National Hot Rods. However,

6105-415: The circumference of the oval track, so many fans choose to view from the ground level inside the infield – leaving the grandstands mostly empty and unsightly. Many combined road course layouts have been abandoned. However, some have enjoyed extended life as venues for testing, driving schools, and amateur race meets . Since 1962, the most famous race continuously held on a combined road course has been

6216-527: The combined road course layout(s). An example of an outfield combined road course can be seen at the Calder Park Raceway in Melbourne , Australia . The Calder Park complex has a 1.119 mi (1.801 km) high-banked oval speedway called the Thunderdome as well as a separate road course. The road course and the oval can be linked via two short roads that connect the front straight of the road course to

6327-480: The competitors, sponsorship dollars on offer as well as major television time, the Australian Superspeedway series shut down after 2001. The majority of the NASCAR and AUSCAR racing in Australia took place at the 1.801 km (1.119 mi), high-banked (24°) Calder Park Thunderdome in Melbourne . The Thunderdome, which was opened in 1987 and was built by multi-millionaire tyre retailer Bob Jane at

6438-687: The country including Cup, Xfinity, and Truck drivers. Despite NASCAR officially sanctioning the NASCAR Advance Auto Parts Weekly Series as a national championship, series such as the CARS Tour , ASA , UARA, and the ACT draw the biggest attention and sanction most of the biggest races in the country. NASCAR is currently the largest stock car racing governing body in the world. While NASCAR sanctions multiple series, it has three national championship touring series that are commonly referred to as

6549-444: The driver. A driver in an IndyCar race at Richmond International Raceway may be subject to as many lateral g-forces (albeit in only one direction) as a Formula One driver at Silverstone . Weather also plays a different role in each discipline. Road racing offers a variety of fast and slow corners that allow the use of rain tires . Paved oval tracks generally do not run with a wet track surface. Dirt ovals will sometimes support

6660-486: The drivers, IndyCar will no longer drive super speedways outside of Indianapolis. Michigan Speedway was part of the series from 2002 to 2007, AutoClub Speedway from 2002 to 2005 and a second time from 2012 to 2015, Pocono was used by IndyCar between 2014 and 2019. In NASCAR they are still an essential part of the racing calendar. The closed and partially demolished Texas World Speedway , was the original "sister track" to Michigan. The two-mile oval, with its 22-degree banking,

6771-474: The early twentieth century had wood surfaces. Indianapolis Motor Speedway 's track surface used to be made entirely of bricks, and today, 3 feet (0.91 m), or one yard, of original bricks remain exposed at the start-finish line. Each was hand laid over a 2-inch (51 mm) cushion of sand, then leveled and the gaps filled with mortar. Before the work was completed, locals nicknamed the track "The Brickyard". A combined road course , colloquially referred to as

6882-518: The early years of the Indy Racing League , the series visited several intermediate tracks. The higher-downforce, normally aspirated IRL-type cars proved to be competitive at several of the tracks. The CART series however, mostly stayed away as the faster, more powerful Champ Cars were generally thought to be too fast for this type of circuit. This became evident at the 2001 Firestone Firehawk 600 , when drivers experienced vertigo-like symptoms, and

6993-531: The end of the 1969 season Ford would make it seven in a row. Richard Petty was tired of winning races but losing the championship, so after a private viewing of Ford's new Talladega and Boss 429 engine, he signed a lucrative deal with Ford. Prior to its first race at the Daytona 500, David Pearson's 427 powered Ford Torino Cobra set a new NASCAR record by being the first to exceed 190 mph (310 km/h) when he qualified at 190.029 mph (305.822 km/h). When

7104-511: The engine. Power output is usually in the range of 500–550 horsepower (373–410 kilowatts ). Tire width is usually limited to 8 in (200 mm). Some entry level classes are called "street stock", and are similar to what is often called " banger racing " in England. Modified stock cars resemble a hybrid of open wheel cars and stock cars. The rear wheels are covered by fenders but the front wheels and engine are left exposed. First popular in

7215-471: The entire nature of the sport. The 1973 oil crisis meant that large displacement special edition homologation cars of all makes were suddenly sitting unsold. Through the balance of the 1970s until 1991, the factory stock sheetmetal over a racing frame meant the cars looked very much like their street version counterparts. Then in 1992, with a highly modified body, and more aerodynamics, stock cars were quickly allowed to differ greatly from anything available to

7326-399: The field will draft each other simultaneously in one large pack. In stock car racing this is often referred to as " restrictor plate racing " because NASCAR mandates that each car on its two longest high-banked ovals, Talladega and Daytona , use an air restrictor to reduce horsepower . The results of pack racing may vary. As drivers are forced to race in a confined space, overtaking

7437-488: The first club president, car owners Ray and Wen Kelley, and John McCarthy; drivers Al Pillion and Ray Roberts; racing officials Lenny Poe and many others. NEMA gradually outgrew its humble beginnings and emerged as a solid professional division. The early rules of NEMA restricted the use of costly specialized racing engines, specifically the twin overhead camshaft Offenhauser . These engines were so powerful and expensive that owners with modified stock engines had little chance at

7548-411: The general public, is sometimes now called "street stock", "pure stock", "hobby stock", "showroom stock", or "U-car" racing. In 1972, SCCA started its first showroom stock racing series, with a price ceiling on the cars of $ 3,000. Some modern showroom stock racing allows safety modifications done on showroom stock cars. Super stock classes are similar to street stock, but allow for more modifications to

7659-535: The history of NASCAR and IndyCar, this oval size was not very common. Until 1990, there were only five examples. Two of these, the Marchbanks Speedway (1.4 miles) and the Trenton Speedway (1.5 miles), were demolished in the 1970s and 1980s, and only three—Charlotte Motor Speedway, Atlanta Motor Speedway and Darlington Raceway—have survived to this day. All other ovals of this type were built after 1994. During

7770-465: The main differences being the bodies closer resemble production cars, use iron engines up to 7.1 litres (434 cu in) with no rear offset and run much larger sprint car tyres on the rear. Stock car racing in the NASCAR mould (AUSCAR) had a following in Australia during the mid-late 1980s and through the 1990s, but with the advent of the Supercars Championship , which took up the bulk of

7881-529: The majority of the races, Dodge was forced to develop a better car of their own. Using the Charger 500 as a basis, they added a pointed nose. This nose was almost a carbon copy of the nose on the 1962 Ford Mustang I prototype. This radical body shape required a wing to remain stable at speeds over 180 mph (290 km/h). They named it the Dodge Daytona after the race they hoped to win. Even though it never won

7992-480: The name "stock car", but is now run using cars specifically built for racing. It originated in the southern United States and later spread to Japan; its largest governing body is NASCAR . Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Canada, Mexico, Brazil, Argentina and Chile also have forms of stock car racing in the Americas . Other countries, such as Australia, New Zealand and

8103-428: The name 'stock car' is usually reserved for that racing class which traces its roots back to these early days in the 1950s, BriSCA F1 Stock Cars , which were previously known as "The Seniors" or "Senior Stock Cars". Despite the physical demands of this full-contact sport, many competitors have been racing for 20 and even 30 years. For the first 10 years of the sport, stock cars were either adapted from road cars, or bore

8214-470: The oldest oval race track, the Milwaukee Mile was originally a race track for horse racing . In NASCAR, 1-mile oval tracks are among the intermediate tracks. IndyCar rates these tracks as short ovals, since IndyCar does not usually run on ovals shorter than 3/4-mile. The 1-mile ovals have lost a great deal of their former importance for oval racing. Most of the racetracks abandoned by NASCAR or IndyCar in

8325-585: The only long, flat tracks on the schedule. Auto Club Speedway, which joined Indianapolis, Michigan and Pocono as the one of four superspeedways used in the Verizon IndyCar Series , was the site of Gil de Ferran 's qualifying lap of 241.428 mph (388.541 km/h) in the CART FedEx Championship Series in 2000 , the fastest qualifying lap recorded at an official race meeting. Due to the low number of spectators or safety concerns by

8436-454: The other manufacturers had openly circumvented the ban. In 1963 GM gave in and openly abandoned compliance, and Chevrolet was allowed to produce the ZO6 427, but it did not immediately enjoy success. Then, in 1964 the new Chrysler 426 Hemi engine so dominated the series in a Plymouth Belvedere "Sport Fury" , the homologation rules were changed so that 1,000 of any engine and car had to be sold to

8547-448: The oval race tracks. As a result, the racetracks have lengths of different accuracy. The following table shows the values that NASCAR, IndyCar and CART/CCWS used to determine the lap speeds and track records. A typical oval track consists of two parallel straights, connected by two 180° turns. Although most ovals generally have only two radii curves, they are usually advertised and labeled as four 90° turns. While many oval tracks conform to

8658-482: The pits of the infant organization were filled to capacity with no less than forty six cars signed-in. Fred Meeker captured the first NEMA victory driving the Kerhan #17 V-8. The years of 1953 and 1954 saw the fortunes of midget racing at their lowest ebb. Total purses of less than what is paid to the winner of a race feature today were common place. The group credited with keeping NEMA afloat during this timewere; Milt Dentch,

8769-778: The public did not have a wide variety of engine choices, and the majority of the buying public at the time was not interested in the large displacement special edition engine options that would soon become popular. However, the end of the Korean War in 1953 started an economic boom, and then car buyers immediately began demanding more powerful engines. Also in 1953, NASCAR recommended that the drivers add roll bars, but did not require them. In 1957, several notable events happened. The Automobile Manufacturers Association banned manufacturers from using race wins in their advertising and giving direct support to race teams. The desire from fans and manufacturers alike for higher performance cars within

8880-417: The public for homologation purposes, the race car rules were further modified, primarily in the interest of safety. This is because race drivers and their cars during this era were subjected to forces unheard of in street use, and require a far higher level of protection than is normally afforded by truly "stock" automobile bodies. In 1963 Ford sold enough of their aerodynamic "sport-roof" edition Galaxies to

8991-468: The public so it would qualify as stock, and with the heavy-duty FE block bored and stroked to the new limit of 427, the top five finishers were all Fords. Chrysler had bored their 413 to create the "Max Wedge" 426, but it still could not compete with the Fords. General Motors' headquarters had genuinely tried to adhere to the 1957 ban, but their Chevrolet division had also constantly tried to work around it, because

9102-482: The public to qualify as a stock part, instead of just 500. This made the 426 Hemi unavailable for the 1965 season. In 1965 Ford adapted two single-overhead-cams to their FE 427 V8 to allow it to run at a higher RPM (called the Ford 427 Cammer ). Ford started to sell "cammers" to the public to homologate it (mostly to dealer-sponsored privateer drag racers), but NASCAR changed the rules to specify that all NASCAR engines must use

9213-442: The public to qualify, hoping to delay the use of aero-bodies until tires could improve. For the 1970 season Dodge raced the 1969 model Daytona, but Plymouth managed to build over 1,920 Plymouth Superbirds , which were similarly equipped to the Daytona. Petty came back to Plymouth in the plus 200 mph (320 km/h) Superbird, and Bobby Isaac won the season championship in a Daytona. NASCAR restricted all "aero-cars" including

9324-554: The public. It also marks the beginning of the Generation 4 car . Modern racing "stock" cars are stock in name only, using a body template that is vaguely modeled after currently available automobiles. The chassis, running gear, and other equipment have almost nothing to do with anything in ordinary automobiles. NASCAR and the auto manufacturers have become aware of this, and for 2013 each brand ( Chevrolet , Dodge , Ford , and Toyota ) have redesigned their racing sheetmetal to more resemble

9435-507: The race started Donnie Allison's Torino lead the majority of the race (84 laps). Towards the end of the race the Torino of LeeRoy Yarbrough chased down the Dodge of Charlie Glotzbach , who had an 11-second lead. It was the first Daytona 500 won on a last lap pass. Things got worse for Dodge when NASCAR, a few months later, finally allowed Ford to run its hemi-headed Boss 429 engine. With Ford winning

9546-861: The race track construction boom of the late 1990s, these tracks began to be labeled with the rather derogatory term "cookie cutter" tracks, as their differences were perceived to be minimal. In 1992, Charlotte became the first intermediate track to install lights and allow for night racing. It is now commonplace for these types of tracks to host night races. Intermediate tracks usually have moderate to steep banking. Almost all modern race tracks that are still used in NASCAR and IndyCar today are of this type. Since their size allows them to compromise high speeds with sightlines, especially tri- and quad-ovals of 1.5-mile length have become commonplace in major racing series that use oval tracks. While intermediate speedways were designed primarily with stock cars in mind, they were also believed to be suited to host Indy cars as well. In

9657-518: The race was cancelled for safety reasons. As of 2020, the IndyCar Series has only one race remaining at a high-banked intermediate track ( Texas ). These tracks began to be removed from the Indy car schedule in the late-2000s and early-2010s due to low crowds and serious crashes, including the fatal accident involving Dan Wheldon at Las Vegas in 2011. Originally a superspeedway was an oval race track with

9768-549: The recognizable bodywork of road cars. By the 1970s, chassis and bodywork had evolved into very specialized forms. In 2001 the ASCAR Racing Series was formed and ran until 2008, the series was a "NASCAR" style racing series that was predominantly run at Rockingham Motor Speedway as well as briefly on the continent. The first season was won by John Mickel . Other notable champions were Nicolas Minassian and Ben Collins who also played as The Stig on Top Gear . The field

9879-575: The regular stock car racing scene because of their all-star grids. Cars are built to an extremely rigid design and feature strong steel guards around almost the entire car. "Stockcars" are divided into three classes: Superstocks, Stock cars, Ministocks (Ministocks predominantly being a non-contact youth class). Superstocks are the top class and are typically powered by V8 engines up to 4.1 litres (248 cu in) which can produce over 370 kilowatts (500 hp). The majority of races are of an individual nature however, unique to New Zealand stock car racing

9990-518: The remains of what had been the most successful spectator sport in the United States. The first officially sanctioned NEMA race took place at the famed Seekonk Speedway May 30, 1953. It was a two billed show in conjunction with the American Racing Drivers Club (ARDC) of New York, with each organization running its own program. The cars and drivers came from the ranks of several other racing organizations which had fallen on hard times and

10101-519: The restrictions of homologation meant that carmakers began producing limited production "special edition" cars based on high production base models. It also became apparent that manufacturers were willing to produce increasingly larger engines to remain competitive (Ford had developed a 483 they hoped to race). For the 1963 season NASCAR engines were restricted to using a maximum displacement of 7.0 liters (427 cu.in.) and using only two valves per cylinder. Also, even with heavy duty special editions sold to

10212-447: The same front straightaway. The now defunct Ascot Speedway featured 1/2 mile and 1/4 mile dirt oval tracks, and Irwindale Speedway features 1/2 mile and 1/3 mile concentric paved oval tracks. Pocono Raceway once had a 3/4 mile oval which connected to the main stretch, and circled around the garage area. In 1991, Charlotte Motor Speedway connected the quad oval start-finish straight to the pit lane with two 180 degree turns, resulting in

10323-403: The same start/finish line, and same pit area, but a mid-course diversion to a winding road circuit in the infield (and/or outfield). At some point, the circuit leads back to the main oval, and completes the rest of the lap. On some of the faster ovals, a chicane is present on long back-straights, to keep speeds down, and create additional braking/passing zones. Some more complex facilities feature

10434-581: The series is the Daytona 500 , an annual 500-mile (800 km) race at the Daytona International Speedway . The series' second-biggest event is arguably The Brickyard 400 , an annual 400-mile (640 km) race held at the Indianapolis Motor Speedway , the legendary home of the Indianapolis 500 , an open-wheeled race. However, the event was excluded from the 2021 schedule in favor of a race on

10545-512: The similar construction boom of the baseball/football cookie-cutter stadiums of the 1960s and 1970s, and the subsequent sport-specific stadium construction boom that began in the 1990s. Most of the oval tracks are located in the United States, Mexico, and Canada. However, there are also many oval tracks elsewhere too, as listed below. Stock car racing Stock car racing is a form of automobile racing run on oval tracks and road courses . It originally used production-model cars, hence

10656-599: The sport's ruling body to reduce the high speeds accommodated by their steep banking since 1988. Other superspeedways used by NASCAR include the Michigan International Speedway (2.0 miles), Auto Club Speedway (known as California Speedway prior to February 2008) (2.0 miles), and Pocono Raceway (2.5 miles). Auto Club Speedway and Michigan are often considered intermediate tracks by NASCAR due to their similarities with 1.5-mile tracks, while Pocono and Indianapolis are sometimes classified separately, as they are

10767-408: The street models of their cars. A stock car, in the original sense of the term, is an automobile that has not been modified from its original factory configuration. Later the term stock car came to mean any production-based automobile used in racing. This term is used to differentiate such a car from a " race car ", a special, custom-built car designed only for racing purposes. The degree to which

10878-414: The top prize money. By 1957 the stock block powered machines had developed to such an extent that this restriction was removed and from this time until 1968, NEMA crowned an Offy non-Offy champion, with one being the overall champion. Along with this improved competition with this rule change came a renewal of interest in midget racing among competitors as well as the fans, who came out in large numbers to see

10989-454: The track's road course. Together the Cup Series and Xfinity Series drew 8 million spectators in 1997, compared to 4 million for both American open-wheel series ( CART and IRL ), which merged in 2008 under the IRL banner. In 2002, 17 of the 20 US top sporting events in terms of attendance were stock car races. Only football drew more television viewers that year. The NASCAR Xfinity Series

11100-465: The traditional midgets, but have less power, some running the USAC Ford Focus Midget engine, and are limited in components they are able to use; all to control cost. Short track motor racing Major forms of oval track racing include stock car racing , open-wheel racing , sprint car racing , modified car racing , midget car racing and dirt track motorcycles . Oval track racing

11211-407: The traditional symmetrical design, asymmetrical tracks are not uncommon. Additional prominent examples: The tri-oval is the common shape of the ovals from the construction booms of the 1960s and 1990s. The use of the tri-oval shape for automobile racing was conceived by Bill France, Sr. during the planning for Daytona. The triangular layout allowed fans in the grandstands an angular perspective of

11322-414: The turns and are considered low banked, superspeedways like Talladega have up to 33° of tilt in curves, Daytona has up to 32°, both are considered high banked. Atlanta is the intermediate track with the highest banking, 28°. Winchester has the highest banking of any active oval track with 37° Track surfaces can be dirt , concrete, asphalt, or a combination of concrete and asphalt. Some ovals in

11433-596: The years. While some tracks use terms such as "speedway" or "superspeedway" in their name, they may not meet the specific definitions used in this article. A short track is an oval track less than one mile (1.6 km) long, with the majority being 0.5 miles (0.8 km) or shorter. Drivers seeking careers in oval track racing generally serve their apprenticeship on short tracks before moving up to series which compete on larger tracks. Due to their short length and fast action, these tracks are often nicknamed " bullrings ". Professional-level NASCAR races on short tracks usually use

11544-640: Was built as a facility for the automotive industry to conduct research and development. Daytona International Speedway was built as a replacement for the Daytona Beach Road Course , which combined the town's main street and its famous beach. Daytona hosts the Daytona 500 , NASCAR's most prestigious race, while the Indianapolis Motor Speedway is home to the Indianapolis 500 and the Brickyard 400 . The longest superspeedway in North America

11655-421: Was created to provide a less dangerous alternative to a traditional concrete wall. The barrier can be retrofitted onto an existing wall or may take the place of a concrete wall completely. Oval tracks are classified based upon their size, surface, banking, and shape. Their size can range from only a few hundred feet to over two and a half miles. The definitions used to differentiate track sizes have changed over

11766-511: Was inspired by off-road truck racing. Unlike the other two national touring NASCAR series, the Truck Series race pickup truck styled bodies, though it is still considered a stock car series because of its similarity. Much like the Xfinity Series, the Truck Series often features Cup Series drivers competing for parts of the season. The Automobile Racing Club of America was founded in 1953 as

11877-555: Was some controversy as Cup Series drivers tended to be more successful than full-time Xfinity drivers. Cup drivers are not eligible to score points in the Xfinity series, and are limited to the number of races they are allowed to race in the Series. Starting in 1995, the NASCAR Truck Series is the third highest ranking stock car series in the United States. The series was the brainchild of then-NASCAR West Coast executive Ken Clapp, who

11988-560: Was the NASCAR Whelen Southern Modified Tour , is another prominent modified tour. In many areas of the country late models are usually the highest class of stock cars in local racing. Rules for construction of a late model car vary from region to region and even race track to race track. The most common variations (on paved tracks) include super late models (SLMs), pro Late models (PLMs), late model stock cars (LMSCs), and limited late models (LLMs). A late model may be

12099-526: Was the site of Mario Andretti's closed-course record of 214.158 mph (344.654 km/h) which stood for 12 years. No major professional series have raced at TWS since the 1990s. The 2.5 mile Ontario Motor Speedway was known as the "Indianapolis of the West", but was bought by the Chevron Land Company in 1980 and partitioned for development. NASCAR and IndyCar use different measuring systems to measure

12210-521: Was used only twice (both in 1987) and has not been used for major motor racing since hosting Round 9 of the 1987 World Touring Car Championship . There have been two distinct oval race track construction "booms" in the United States. The first took place in the 1960s, and the second took place in the mid-to-late 1990s. The majority of tracks from the 1960s boom and the 1990s boom have survived, but some tracks failed to achieve long-term financial success. Incidentally, these two booms loosely coincided with

12321-469: Was usually populated by professional or semi-professional stock car drivers, however notable drivers who were famous from other areas of motorsport either took part in single races or for one complete season, they included Colin McRae , Jason Plato , Matt Neal , Darren Manning , Max Papis , John Cleland and former NASCAR drivers Brandon Whitt and Randy Tolsma . The modern BriSCA Formula 1 Stock Cars are
