115-476: The NASCAR Xfinity Series ( NXS ) is a stock car racing series organized by NASCAR . It is promoted as NASCAR's second-tier circuit to the organization's top level Cup Series . NXS events are frequently held as a support race on the day prior to a Cup Series event scheduled for that weekend. The series was previously called the Budweiser Late Model Sportsman Series in 1982 and 1983,

230-486: 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

345-796: 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

460-618: 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

575-400: 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,

690-543: A few marquee events on the network itself. From 2007 until 2014, ESPN was the home of the renamed Nationwide Series. Generally four races per season aired on ABC, with the remainder on ESPN, ESPN2 , and ESPNews . Early in ESPN's run, ESPN Classic was used for NNS overflow, however with less carriage of that network, this practice ended. Fox Sports made a return to the series, airing the 2011 Bubba Burger 250 at Richmond on Speed Channel , as ESPN gave up its exclusive rights to

805-495: 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)

920-411: 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

1035-470: 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

1150-613: A non-Championship race. The following year the Mexican Grand Prix became a full World Championship event. The circuit remained part of the F1 calendar through 1970, when spectator overcrowding caused unsafe conditions. When F1 returned in 1986, the circuit boasted a new pit complex, as well as improved safety all around, but left again after 1992 due to safety concerns. In 2001 CIE and Forsythe Racing tasked D3 Motorsport Development with revamping

1265-684: 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

1380-487: A result, beginning with the 2011 season, NASCAR implemented a rule stating that drivers could only compete for the drivers' championship in one of three national series (Cup, Xfinity, and Truck) of the drivers' choosing. On October 26, 2016, NASCAR announced plans to limit Cup participation in the lower series starting in 2017. Cup drivers who were competing for points in the Cup Series with at least five years of experience in

1495-579: 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

1610-615: A series of sharp turns entering and exiting the Foro ; re-entering the Peraltada halfway through. After the Peraltada comes the long 1.2 km front straight. During the original turbo era in Formula One the faster cars were regularly clocking speeds of up to 330 km/h (205 mph) on the straight. In the 2005 NASCAR Busch Series season, there was a chicane on the main straightaway to slow

1725-490: 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

1840-453: 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

1955-512: A three-race test of unleaded gasoline in this series that began on July 29, 2006, with a race at Gateway International Raceway . The fuel, Sunoco GT 260 Unleaded, became mandatory in all series starting with the second weekend of the 2007 series, with Daytona being the last race weekend using leaded gasoline. Another distinction between the cars started in 2008: Goodyear had developed a rain tire for NASCAR road course racing in both series but NASCAR had yet to use them under race conditions by

2070-570: 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

2185-594: Is 1:14.758, set by Max Verstappen driving for Red Bull Racing in the qualifying of the 2019 Mexican Grand Prix . As of September 2024, the fastest official race lap records at the Autódromo Hermanos Rodríguez are listed as: The Autódromo includes a baseball stadium inside turn 14 (Peraltada). The stadium, called Estadio GNP Seguros since 2024 and formerly known as Foro Sol, was home to the Diablos Rojos del México and also hosts music concerts. Some of

2300-878: Is located within the public park of the Magdalena Mixhuca Sports City in southeast Mexico City. The circuit is owned by the Government of the City, but is currently operated under concession by Corporación Interamericana de Entretenimiento (CIE) through OCESA, one of CIE's subsidiaries. CIE also organizes the NASCAR and Desafío Corona races in this circuit and rents the circuits to other parties, including race organizers, automobile clubs and track amateurs for fees that are controversial due to their disproportionately high amounts compared to other ex-F1 courses. The NASCAR Xfinity Series started racing at Autódromo Hermanos Rodríguez in

2415-478: 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

2530-544: 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

2645-497: 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

2760-668: Is used at least twice a year, with two double-feature events featuring the NASCAR Toyota Series and the NASCAR Mexico T4 Series . The oval configuration also forms the base of the FIA Formula E Championship circuit for the Mexico City ePrix ; the oval is raced clockwise, but there is a chicane prior to the entrance of turn 4, with a second chicane on the backstretch, followed by a modified Foro Sol section that exits for

2875-489: 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,

2990-569: The 2006–07 season using the full-track configuration used by Formula One . Alex Yoong from Malaysia won the sprint race and Oliver Jarvis from the United Kingdom won the feature race. In the 2007–08 season , Jonny Reid from New Zealand won the sprint race and Adam Carroll of Team Ireland won the feature race. Built in the Magdalena Mixhuca public park in 1959, the circuit hosted its first Formula One Grand Prix in 1962, as

3105-503: 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

3220-847: The Camaro SS , after initially running the Impala and then the Zeta-based Camaro (which coincided with GM's Cup car being its four-door Zeta counterpart, the Holden VF Commodore based Chevrolet SS , being used in Cup at the time). Ford uses the Mustang GT . Toyota runs the Camry , reconfigured in 2015 to resemble the current production model. Toyota announced they would be running the Supra starting in 2019, replacing

3335-521: The Modified and Roadster series in 1948 and Strictly Stock Series in 1949). The sportsman cars were not current model cars and could be modified more, but not as much as Modified series cars . It became the Late Model Sportsman Series in 1968, and soon featured races on larger tracks such as Daytona International Speedway . Drivers used obsolete Grand National cars on larger tracks but by

3450-633: The NASCAR Busch Grand National Series from 1984 through 2002, the NASCAR Busch Series from 2003 through 2007, and the NASCAR Nationwide Series from 2008 through 2014. Since 2015, it is sponsored by Comcast via its consumer cable and wireless brand Xfinity . The series emerged from NASCAR's Sportsman division, which had been formed in 1950 as NASCAR's short track race division. It was NASCAR's fourth series (after

3565-557: 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

3680-457: The Peraltada curve is slightly banked, allowing even more speed through the corner. It was at this corner that the younger Rodríguez crashed, due to suspension failure. After the last F1 Mexican Grand Prix in 1992, a baseball stadium called the "Foro" was built on the inner part of this curve. When the Champ Car series began using the track in 2002, the Peraltada curve was partially bypassed by

3795-651: 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,

3910-407: The current turbocharged Formula One cars , which eliminate the adverse effects of altitude present in naturally aspirated cars. However, the modern V6 hybrid turbo Formula One cars actually managed to reach top speeds in excess of 370 km/h (230 mph) down the main straight. The maximum speed recorded in a 2024 Formula One car was 362.5 km/h (225.2 mph), established at the end of

4025-571: The "Solana Complex" in English. In September 2002, Mexico's fourth and, then most recent, F1 driver Héctor Rebaque 's achievements both in F1 and CART were recognized by renaming turn 6 of the Autodromo as Recorte Rebaque instead of the previous name of Recorte de Gran Premio . In 2015, turn 17 was named in honour of Nigel Mansell , twice winner of the Mexican Grand Prix in 1987 and 1992 and

4140-592: 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

4255-481: The 2005 season and ended in the 2008 season. Martin Truex Jr. won the race in 2005, and Denny Hamlin won in 2006. For the 2007 race, the chicane was removed to increase passing opportunities down the front straight and into turn 1, and Juan Pablo Montoya from Bogotá , Colombia , won the race. Kyle Busch was the winner of the race in 2008. The A1 Grand Prix series started racing at Autódromo Hermanos Rodríguez in

4370-409: 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

4485-677: The Camry, which had been run in the series since Toyota joined the Xfinity Series in 2007. Dodge teams used the Challenger R/T model, despite the manufacturer pulling all factory support after 2012 (though it continued in Canada as FCA Canada still supports the Pinty's Series). Following Dodge's exit, smaller underfunded teams continued to run second-hand Challenger chassis without factory support (thus earning

4600-504: The Cup cars. However, the cars still used V6 engines. The cars gradually became similar to Cup cars. In 1995, changes were made. The series switched to V-8s with a compression ratio of 9:1 (as opposed to 14:1 for Cup at the time). The vehicle weight with driver was set at 3,300 pounds (as opposed to 3,400 for Cup). The body style changes, as well as the introduction of V-8s, made the two series' cars increasingly similar. The suspensions , brake systems, transmissions, were identical between

4715-619: The Cup drivers because it gives them the opportunity to drive with more seasoned veterans. In 2007, the NASCAR Cup Series began racing with the Car of Tomorrow , a radically new specification different from the NXS. NASCAR Cup Series drivers have admitted that driving the Xfinity car the day before the race does little to help with the NASCAR Cup Series race, as the cars differ greatly. This loosely resulted in

4830-467: 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

4945-455: The Formula 1 layout. After turn 2 (Formula E track), the track will turn left instead of right and the extended part includes a 4-turn sequence before going back to the original circuit and the stadium section. Before the 1986 Formula One race, the first turn (now turns 1-3) was named in honour of Moisés Solana , Mexico's third F1 driver. It is still called Ese Moisés Solana , often referred to as

5060-581: The Gold Roof. The 2012 World Championship held at Skegness was won by 217 Lee Fairhurst. The 2013 World Championship will be held at King's Lynn on Saturday 21 September. Autodromo Hermanos Rodriguez The Autódromo Hermanos Rodríguez is a 4.304 km (2.674 mi) motorsport race track in Mexico City , Mexico, named after the racing drivers Ricardo Rodríguez (1942–1962) and Pedro Rodríguez (1940–1971). The circuit got its name shortly after it opened when Ricardo Rodríguez died in practice for

5175-557: The Mexican Grand Prix as the 19th round of the provisional schedule for the 2014 season , but it was not on the final schedule. The Mexican Grand Prix was listed on the 2015 Formula One calendar published by the FIA on 3 December 2014, with Formula One making its return to the circuit with the race on 1 November 2015. The racetrack is also home to Electric Daisy Carnival (EDC Mexico), a music festival attended by over 200,000 people. Designed as his thesis by student Óscar Fernández in 1953,

5290-524: The NASCAR Cup Series Chase for the Championship. Unlike the Cup Series, whose Chase consists of four rounds, the Xfinity Series and Truck Series both use a three-round format. After each of the first two rounds, the four Chase grid drivers with the fewest season points are eliminated from the grid and Chase contention. In the 1980s, races were sparsely shown, mainly by ESPN if they were covering

5405-579: The NXS live or near live during the 2008 season. ONE continued to air highlights packages of each race until the end of 2014. Broadcasts of the series are now exclusively shown on the Fox Sports pay TV channels. All races are live on TSN channels using FOX's or NBC's coverage. Also, races are broadcast on RDS or RDS2 in French using the world feed produced by NASCAR. In 2012, Motors TV broadcasts all Xfinity races live, delayed and highlights, until 2018 when

5520-424: The NXS. This can be for any number of reasons, most prominent or often claimed is to gain more "seat time", or to familiarize themselves with the track. Examples of this would be Dale Earnhardt , who won the very first NXS race, and Kyle Busch , who has won the most races in NXS history. In recent years, this practice had been dubbed "Buschwhacking" by its detractors. The colloquialism originated when Anheuser-Busch

5635-468: The Nationwide Series would not return to Mexico City in 2009 , and in 2012 they announced that it would not be returning to Montreal in 2013 . While the Xfinity Series races at nearly all the same tracks as the Cup Series, there are some stand-alone weekends in the Xfinity Series, with the only one being Portland in 2024 . In 2016, the NXS and Truck Series adopted a playoff format similar to

5750-514: 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

5865-538: 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

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

The Diablos Rojos later left the then-called Foro Sol in order to build a new baseball stadium named Estadio Alfredo Harp Helú , which

6210-469: 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

6325-526: 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

6440-504: The cars down. They also introduced a curve between the short course and the Ese del Lago to bypass the latter, but avoiding the stadium detour. The Grand Prix circuit underwent a significant renovation under the direction of Hermann Tilke for the return of Formula One in 2015 . The front straight was slightly extended and reprofiled to accommodate a new media center and paddock. The iconic esses between turns 7 and 13 were significantly modified;

6555-475: 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,

6670-447: The channel ceased operations. In Portugal , SPORT TV broadcasts every Xfinity races live. In the United Kingdom , the Xfinity races—in full and highlights—are available on Premier Sports 2 . All races are live on Sports Illustrated Television channels using FOX's or NBC's coverage with highlights on Fox Sports Asia . Since the early days of the Xfinity Series, many NASCAR Cup Series drivers have used their days off to drive in

6785-486: The circuit has an elevation of 2,238 m (7,342 ft); the thin air causes difficulties for both the drivers and their cars. It also reduces the levels of aerodynamic drag that cars experience, meaning that higher downforce setups can be used with less impact on straight-line speed. The circuit has an extremely fast final corner (the Peraltada , turn 17) before a long start/finish straight, and thus reminded some of Monza ; however, unlike Monza's Parabolica curve,

6900-675: The circuit. A redesign to include the Foro and a complete upgrade of the circuit was done. It saw a record crowd of 402,413 people attend a round of the CART Championship in 2002. It was announced in May 2012, that the circuit would again host the Mexican Grand Prix from 2013, in a five-year deal that would see it replace the European Grand Prix in Valencia , but this did not happen. The FIA listed

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

7245-449: The cup race at the same track. Starting in 1990, more races began to be shown. By the mid-1990s, all races were shown. Most standalone races were aired on TNN , which helped grow coverage of the series, while races that were companion races with Winston Cup dates mostly aired on the network airing the Cup race. TNN aired some of these races, which also aired on CBS , NBC , ESPN , ABC and TBS . From 2001 until 2006, Fox Sports covered

7360-430: The end of Busch sponsorship. Critics claim that NASCAR Cup Series drivers racing in the NXS take away opportunities from the NXS regulars, usually younger and less experienced drivers. On the other hand, many fans claim that without the NASCAR Cup Series stars and the large amount of fan interest they attract on their own races, the NXS would be inadequate as a high-tier division. In addition, many NXS drivers have welcomed

7475-481: 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

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

7705-479: The entire first half of the Busch Grand National season, while NBC and TNT both aired races during the second half, with Turner Sports producing all the coverage for both networks. However, in even numbered years, coverage was changed, with the opening race at Daytona airing on NBC in 2004, on TNT in 2002 and 2006 (due to NBC's coverage of the Winter Olympics ) and the track's July race airing on FX. Large portions of Fox's coverage aired on sister network FX , with

7820-471: 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

7935-611: The final eight races of the 2024 season. The NXS is available in most Latin American countries on cable and satellite TV. Since 2006, Fox Sports 3 (formerly called SPEED until 2013) carries live coverage of all events. The races are also shown on Fox Sports Latin America , some of them live and some tape-delayed depending on the network's schedule. Televisa Deportes also broadcast a 30-minute recap every Sunday morning on national television in Mexico . In Brazil , BandSports carries all three series. Network Ten 's additional high-definition service, ONE , began broadcasting races from

8050-421: The front wheel on the Next Gen. The then Nationwide Series unveiled its "Car of Tomorrow" (CoT) at the July 2010 race at Daytona International Speedway . Before being fully integrated in the 2011 season, it was also used in 2010 races at Michigan International Speedway , Richmond International Raceway and Charlotte Motor Speedway . The Xfinity CoT has important differences from the NASCAR Cup Series CoT , and

8165-403: The full Peraltada, and a third chicane midway through the Peraltada (turns 1 and 2 of the oval). FIA Formula E track design was modified by Agustin Delicado Zomeño. Starting from season 3 (2016–2017), the first chicane is removed and now it is a right-hand corner. In season 6, the track is extended and the two chicanes at the back straight and the Peraltada are removed. The track also uses more of

8280-411: 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

8395-465: The inception of the touring format in 1982 , the series used older compact cars. Short track cars with relatively small 300 cubic inch V-8 motors were used. Drivers used smaller current year models featuring V6 motors. The modern-day Xfinity Series was formed in 1982, when Anheuser-Busch sponsored a newly reformed late-model sportsman series with its Budweiser brand. In 1984, the series switched sponsorship to Anheuser-Busch's Busch Beer brand and

8510-450: The limited visibility at the exit of turns 2 and 4. This is because the Foro Sol baseball stadium is located inside turns 1 and 2; and several trees are located inside turns 3 and 4. During the 2006 season, two accidents occurred in the oval track during NASCAR Mexico T4 Series events, which took several drivers out of the race, with some needing hospital treatment. The oval configuration

8625-465: 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

8740-529: 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

8855-428: 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

8970-424: The new Nationwide Series car making its debut in the 2010 Subway Jalapeño 250 at Daytona International Speedway. This car has a set-up closer to the current Cup car and some Cup drivers who have tested the car say it has similar handling characteristics. The new car has gone full-time since the 2011 season. In 2007, six out of the top ten drivers in the final point standings were Cup regulars, with Jason Leffler being

9085-2064: The nickname "Zombie Dodges"). As a result of a rules change after the 2018 season, all Challenger chassis were rendered ineligible for competition, as the series made the switch to composite body panels. Since FCA had pulled factory support years earlier, no new body was submitted for competition, ending the possibility of running a Challenger chassis in the series.

Allgaier Stock car racing 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

9200-493: The non-Championship 1962 Mexican Grand Prix . Ricardo's brother Pedro was also killed behind the wheel nine years later. Since 2015 , the track has once again hosted the Formula One Mexican Grand Prix , an event it previously hosted in two separate periods on a different layout, the last occasion of which was in 1992 . Since 2021 the event has been held under the name "Mexico City Grand Prix". The circuit

9315-598: The now-retired Generation 4 style car. The body and aerodynamic package differs from the NASCAR Cup Series cars, marketing American pony cars from the 1960s such as the Ford Mustang , Dodge Challenger , and Chevrolet Camaro . The change to share the same CoT chassis as the Cup series resulted in the wheelbase being lengthened from 105 to 110 inches Each manufacturer uses a distinct body design (similar to 1960s muscle cars), built within strict aerodynamic guidelines provided by NASCAR. The Chevrolet car body currently resembles

9430-519: The only non-Cup driver in that group to win a race in 2007. This number decreased from 2006 when 8 out of 10 drivers were Cup regulars. The decreased number is attributed to Cup regulars running only partial schedules, allowing for more NXS regulars to reach the top ten in points. However, the champions from 2006 to 2010 were all Cup regulars driving the full series schedule ( Kevin Harvick , Carl Edwards , Clint Bowyer , Kyle Busch , and Brad Keselowski ). As

9545-454: 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

9660-454: The others air on NBCSN (until 2020) or, during the Olympics, CNBC or USA Network (prior to 2020). Since 2021, USA Network had carried all races not aired on NBC or Fox Sports. On July 28, 2023, it was announced the Xfinity Series will move exclusively to The CW in 2025 as part of a seven-year deal. It was then announced on April 11, 2024, that the move would begin a year early to broadcast

9775-561: The prolific, high radius turns largely diminished and some replaced with fixed angle turns. The baseball field portion of the track was also altered to a low-speed left-right combination that bypassed the first half of the Peraltada, allowing the cars to re-enter the Peraltada halfway through the corner. At 4.304 kilometres (2.674 mi), the course is 170 metres (560 ft) shorter than the previous Grand Prix layout, and Mexican Grand Prix organizers predicted lap times of around 75 seconds and speeds in excess of 328 km/h (204 mph) for

9890-778: 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

10005-417: 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

10120-468: 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

10235-482: 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

10350-492: 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

10465-554: 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

10580-423: The race because of programming conflicts. In 2015, the NXS returned to Fox Sports during the first half of the season. Like the previous time Fox held rights to the series, most of the coverage aired on cable, though this time on FS1 . Four races aired on Fox itself until 2019, when all races moved to FS1. The second half of the NXS season is televised by NBC Sports . Four to five races air on NBC itself, while

10695-507: 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

10810-549: 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

10925-575: 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

11040-519: 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

11155-415: The scene of his daring pass around the outside of Gerhard Berger in 1990 . On September 20, 2016 Adrián Fernández 's achievements have been recognized by the naming of turn 12 of the Autodromo in his honour. The official lap record for the current circuit layout is 1:17.774, set by Valtteri Bottas driving for Mercedes in the 2021 Mexico City Grand Prix , while the unofficial all-time track record

11270-650: 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

11385-595: The series would be allowed to compete in up to 10 NXS races, but are banned from racing in the series' regular season finale, Chase, and Dash 4 Cash races. In the early 1980s, teams were switching from the General Motors 1971–77 X-Body compact cars with 311-cubic inch engines. Later, teams were using General Motors 1982–87 G-body cars. Ford teams have used the Thunderbird cars consistently. In 1989, NASCAR changed rules requiring cars to use current body styles, similar to

11500-477: The sponsorship after the 2007 season ; Nationwide Insurance took over the sponsorship for the 2008 season, renaming it the Nationwide Series . The Nationwide sponsorship was a seven-year contract, and did not include the banking and mortgage departments of Nationwide. The sponsorship reportedly carried a $ 10 million commitment for 2008, with 6% annual escalations thereafter. On September 3, 2014, it

11615-473: The start/finish straight. The circuit also features an oval layout due to the inclusion of a flat turn that goes from the middle of the main straight to the beginning of the backstretch of circuit. Unlike the road course, the oval is raced in counter-clockwise direction (except for the Formula E race). The oval configuration of this Mexico City facility is arguably the most dangerous racetrack in Mexico, because of

11730-408: 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

11845-472: The time NASCAR abandoned the program for the Cup Series in 2005 (the Cup Series eventually used rain tires at the 2020 Bank of America Roval 400 and 2021 Texas Grand Prix ), but the Busch Series continued to use rain tires in races at Autodromo Hermanos Rodriguez and Circuit Gilles Villeneuve , since the races could not be planned with rain dates. When rain started to fall at the 2008 NAPA Auto Parts 200 ,

11960-498: The tires were used in the rain for the first time. Another distinction was added in 2012, when NASCAR changed the fuel delivery system in the Cup cars from carburetion to fuel injection . NXS cars continue to use carburetors. Furthermore, with the Cup Series' switch to Next Gen car in 2022, Xfinity cars (as well as Truck Series vehicles) continue to use traditional five-lug steel wheels and centered door numbers, as opposed to an aluminum center lock wheel and numbers being placed behind

12075-454: 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

12190-437: The two series, but The Car of Tomorrow eliminates some of these commonalities. The Car of Tomorrow is taller and wider than the Generation 4 -based vehicles in the then-Nationwide Series, and until 2010, it utilizes a front "splitter", opposed to a front valance. The Car of Tomorrow also set pole speeds slower than the NXS cars at companion races. Previously, Busch Series cars used fuel that contained lead . NASCAR conducted

12305-525: Was announced that Comcast would become the new title sponsor of the series via its cable television and internet brand Xfinity , renaming it the Xfinity Series . In 2016 , NASCAR implemented a seven-race Chase system similar to the one used in the NASCAR Cup Series. Xfinity race fields have varied in the number of drivers. Prior to 2013 , the grid size resembled its Cup counterpart with 43 cars per race; that year, it shrank to 40 maximum cars. The field

12420-511: Was further reduced in 2019 and 2020 to 38 and 36, respectively. During the 2020 season, fields were temporarily increased to 40 cars again to accommodate part-time teams that were otherwise unable to qualify due to such sessions being canceled in the wake of the COVID-19 pandemic . On March 6, 2005 , the series held its first race outside the United States, the Telcel-Motorola 200 . The race

12535-652: Was held in Mexico City , Mexico at the Autodromo Hermanos Rodriguez , a track that has held Formula One and Champ Car races in the past. It was won by Martin Truex Jr. On August 4, 2007 , the series held its second race outside the United States, at the Circuit Gilles Villeneuve in Montreal, Quebec , another road course. It was won by Kevin Harvick , while Quebec native Patrick Carpentier finished second. In July 2008 , NASCAR announced that

12650-454: 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

12765-566: Was renamed the Busch Grand National Series . "Grand National" was dropped from the series' title in 2003 as part of NASCAR's brand identity (the "Grand National" name was later used for the Busch East and Winston West series as part of a nationwide standardization of rules for NASCAR's regional racing; both series are now run under ARCA Menards Series banner after NASCAR purchased the organization in 2018). Anheuser-Busch dropped

12880-505: 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

12995-560: 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

13110-399: Was the main sponsor of the series by combining the name "Busch" with the term " bushwhacker ," but it has gradually fallen out of use since Anheuser-Busch's sponsorship ended. Other nicknames, such as Claim Jumper (for when Nationwide was the series sponsor), and Signal Pirate (for the current sponsor Xfinity) have never really caught on, although the generic term "Cup leech" is often used after

13225-469: 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
