70-482: The Lausitzring has a feature which is unique in continental Europe: a high-speed oval race track , as used in the United States by NASCAR and IndyCar . The 3.256 km (2.023 mi) tri-oval (similar to Pocono Raceway ) was used twice in 2001 and 2003 by open seater CART races named German 500 (won by Kenny Bräck and Sébastien Bourdais ), plus a few British SCSA races. In 2005 and 2006,

140-403: 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

210-510: 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

280-626: 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

350-422: 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

420-480: A confined space, overtaking 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

490-405: 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

560-496: 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

630-445: 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

700-405: A major event. There were three serious accidents at the facility in its first year of operation. On 25 April 2001, former Formula One driver Michele Alboreto was killed on the test oval after crashing at high speed due to a tyre failure. Alboreto was testing an Audi R8 in preparation of his participation at the 2001 24 Hours of Le Mans . Just over a week later, on 3 May 2001, a track marshal

770-449: 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,

840-585: A replacement for the AVUS in Berlin . The construction of the EuroSpeedway Lausitz began on 17 June 1998. The facility was officially opened during a public ceremony on 20 August 2000. Winding in the infield of the high-speed tri-oval, there is a regular road race track for automobile and motorbike racing, using various track configurations up to roughly 4.562 km (2.835 mi). The stands around

910-405: 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

980-417: 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

1050-461: 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

1120-615: Is represented at 150 locations. It is one of the largest private training companies in Germany. On November 1, 2017, Dekra acquired the EuroSpeedway Lausitz as a test site, especially for autonomous driving . The DEKRA e. V. association has nearly 44,000 members. They are primarily companies with fleets of commercial vehicles, such as carriers, that are supported technically and commercially by Dekra. The association also provides employee training for companies engaged in

1190-560: 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

1260-449: Is the world’s largest non-listed expert organization in the TIC sector (Testing, Inspection, Certification) founded in Berlin , Germany in 1925 as Deutscher Kraftfahrzeug-Überwachungs-Verein (German Motor Vehicle Inspection Association). At 28 million per year worldwide, Dekra inspects more vehicles than any other organization. Dekra is active in the field in more than 20 countries across

1330-903: Is wholly owned by DEKRA e. V. The vision for the company’s 100th birthday in 2025 is that Dekra will be the global partner for a safe, secure and sustainable world. With a platinum rating from EcoVadis, Dekra is in the top one percent of sustainable businesses ranked. Other products and services include damage reports, accident analyses and technical reports, industrial testing services, initial and in-service training, temporary work , outplacement, certifications, environmental protection, materials testing, product testing, building surveys, corporate consultancy and specialist publications. Dekra's range of services also includes safety engineering and occupational medicine support for businesses in accordance with professional association regulations. In former West Germany, Dekra operates as an "officially recognised inspection organisation". In former East Germany and Berlin,

1400-682: 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

1470-548: 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

1540-502: The German Formula Three Championship held races at the oval, with a pole position lap average speed of 251.761 km/h (156.437 mph) and a race average of 228.931 km/h (142.251 mph). As far back as 1986, in the former communist East Germany , it was planned to convert one of the huge open coal mine pits into a race track. In the late 1990s, this idea was taken up again in order to build

1610-424: 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

1680-867: 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

1750-683: 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

1820-509: The German Women's Volleyball League. Dekra was the official sponsor of the DFB (German Football Association) football referees from 2003 to 2021. Dekra gained worldwide recognition between 1991 and 1995 as the exclusive advertising partner of Formula 1 driver Michael Schumacher . Dekra offers free visual and functional inspection in all of its branches under the name SafetyCheck during

1890-647: The Group. Dekra was founded in Berlin in 1925 as Deutscher Kraftfahrzeug-Überwachungs-Verein (German Motor Vehicle Inspection Association). When National Socialists come to power in 1933, Dekra follows a consciously neutral course with regard to the National Socialist state and the Nazi Party under the management of Kurt Möhring. From 1937, Dekra can no longer maintain its neutral course with regard to

1960-521: 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

Starting in 1942, the focal point of orders shifts from vehicle inspection to damage and time estimates. After World War II, former Dekra engineers resume

2100-629: 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 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

2170-460: The agenda. Oval track racing Oval track racing is a form of motorsport that is contested on an oval-shaped race track . An oval track differs from a road course in that the layout resembles an oval with turns in only one direction, and the direction of traffic is almost universally counter-clockwise. Oval tracks are dedicated motorsport circuits, used predominantly in the United States. They often have banked turns and some, despite

2240-441: The association also has the status of a "technical testing centre for automobile traffic" with the accompanying expertise (including the conducting of driving tests and assessments for the purpose of obtaining operating licences). Dekra operates 480 branches throughout Germany and carries out regular vehicle inspections at 38,500 inspection sites (workshops). The Dekra Academy, which is responsible for initial and in-service training,

2310-408: 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

2380-514: 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

2450-415: 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

2520-601: 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

2590-522: The company's work in 1946. Stuttgart becomes the new location of the head office. After the introduction of the main vehicle inspection in 1951. In 1961, Dekra was recognised as an official inspection association. The first Dekra training centre was opened in Wart in 1974. DEKRA AG was founded in 1990 and took over the work of the association. DEKRA ETS was founded in 1991 and took on technical safety, materials testing and construction tasks. DEKRA Umwelt

2660-444: 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

2730-486: 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,

2800-474: 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

2870-526: 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

2940-413: The entire facility was sold to the vehicle inspection company Dekra , which announced plans to modernize it and use it as a proving ground for road car innovations. Amid fears that the purchase would mark the end of public racing events at the circuit, Dekra announced that it would not organize such events, but other companies would remain welcome to organize them and Dekra would rent the circuit to them for

The latest additions were Finland, Mexico and Chile. With approximately 48,646 employees and revenues of more than €3.8 billion, Dekra is the largest inspection company in Germany and one of the world’s leading expert organizations. By its own account, it is the European market leader. The group focuses on the inspection of vehicles and technical systems, but also offers other services like testing and certification. Dekra has had its headquarters in Stuttgart since 1946. Business operations are carried out by DEKRA SE, which

3080-552: 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

3150-574: The meeting was set by Nicolas Lapierre and was 0.45 seconds slower than the lap record for the 4.345 km (2.700 mi) circuit held by Heikki Kovalainen . The EuroSpeedway played host to Round 6 of the 2010 Red Bull Air Race World Championship . As the last two events of the 2010 Championship (Rounds 7 and 8) were cancelled, the 2011 series was cancelled as well. The series then suffered an overall three-year hiatus before finally returning in September 2016 and September 2017. On 1 November 2017,

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 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

3290-477: 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

3360-607: 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

3430-448: 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

3500-431: The pit exit following a late stop for fuel and the car slid onto the tri-oval, where it was hit from the side by Alex Tagliani 's car at full speed. The impact split the front of Zanardi's car from the rest of it and caused the driver to suffer a traumatic amputation of both of his legs. Tagliani was not seriously injured, having suffered some bruising as a result of the crash. The official EuroSpeedway anthem "Speed Kings"

3570-727: The purpose. The DTM has continued to organize races at the circuit ever since. As of May 2024, the fastest official race lap records at Lausitzring are listed as: On 1 November 2017, Dekra acquired the Lausitzring as a test site, especially for autonomous driving . In April 2019 test and verification of communication elements took place on the Lausitzring. Participants were Ford , Samsung , Vodafone , Huawei , LG Electronics and others. Topics were communication matters. Dekra organised also an Open-air festival , that took place in May 2019. Complementary racing events, such as DTM are on

3640-861: 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

3710-529: 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

3780-493: The safe transport of dangerous goods or substances. DEKRA e. V. holds 100% of the shares in DEKRA SE. It acts as a holding company for the subsidiaries organised into the following three business units: Overall, the group has more than 230 subsidiaries and holdings in over 50 countries. In fiscal year 2022, the expert organization achieved sales of €3.8 billion. At the end of 2022, Dekra employed around 48,646 people across

3850-447: 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

3920-403: 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

3990-406: 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. Dekra Dekra (stylized in all uppercase in its logo)

4060-612: 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

4130-618: 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 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

4200-407: 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

4270-624: The tri-oval have a capacity of 120,000, while the huge main grandstands have 25,000 seats, and unlike many circuits, the entire circuit can be seen from the main grandstand. Next to the racing facility, there is a test oval with two long straights connecting two steeply banked U-shaped corners. The test oval has a total length of 5.800 km (3.604 mi), with each of its two straights measuring about 2.5 km (1.6 mi) in length. All tracks can be connected to form an 12.030 km (7.475 mi) long endurance racing course, but so far this option has been used only for testing and never as part of

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

4410-596: 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

4480-781: 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

4550-421: 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

On 13 July 2010, DEKRA AG was renamed DEKRA SE ( Societas Europaea ), becoming a European Company. Dekra has been a technical partner and sponsor of the DTM (German Touring Car Masters) since 1989. Since 2022, Dekra has also been an official partner of
