TypeRacing simulation

iRacing, previously, is a subscription-based racing simulation online video game developed and published by Motorsport Simulations in 2008. All races and practice sessions are hosted on the publisher's servers. The game simulates real world cars, tracks, and racing events, and enforces rules of conduct modeled on real auto racing events.[1][2][3]


iRacing only allows the use of a realistic cockpit view in official racing, but will allow for other camera views in test sessions or other sessions if the host or organizer allows. Most users use a force feedback steering wheel[citation needed] with gas, brake, and clutch pedals, as well as H-pattern shifters and/or sequential shifters.[citation needed] The gameplay is developed to mimic auto racing in as much detail as possible.


When the user account is created, the player starts with a Rookie-level license in all categories. In order to advance onto the "D"-level license and beyond, the user must complete a number of races with little to no accidents, off-track incidents, or losses of control. As the user achieves the higher-level licenses, they qualify to compete in more official series. The licences are (after progressing past Rookie-level): D, C, B and A. Pro/WC licences are available for those who can qualify.

For the standard official series managed by iRacing, each calendar year is normally divided into four 12-week seasons, with all driving sessions in a series taking place on one track for each week during the 12-week seasons.[4] Drivers can participate in practice, qualifying, license time trials, and race sessions. The week between each season is referred to as "week thirteen", and has its own set of series which change track each day. During Week 13 drivers cannot complete time-trials, and so cannot add to their licence level.[5] Week 13, in general, has a more relaxed attitude, with an emphasis on fun, rather than competition. Week 13 is often plagued with server issues, as the purpose of the week is for the implementation of software updates. There are also non-standard series, examples of which are the four-week Rookie series, IndyCar, Skip Barber and Grand-Am Premier series, and Pro series.[6] Races that are organized by members do not have to follow any official schedule.

The series are divided into four main categories, oval and road and dirt (off-road) variations of both, which are further divided into several license level series from Rookie to Pro, and a driver must earn each license to be eligible to participate in official race week sessions at their license level. If not qualified for the correct license for a series, drivers can still participate in practice sessions.[7] Earning a higher license involves both participation in competitions on a driver's current highest license level and achievement of a minimum safety record. The requirements for advancing and the licenses themselves are category-specific — in other words, a driver has a separate license for each of the categories.[8]

Racing within the service is managed by a sanctioning body called FIRST. The detailed rules for official competition are published in the FIRST Sporting Code, which registered members of the service are expected to read and agree to abide by as part of the games Terms of Service.[9] iRacing run several different official series, but members are also free to organize their own online sessions that are hosted on servers run by iRacing. In 2012, iRacing increased the ability for users to run their own seasons through "Leagues" where, for a fee, users manage their own league, recruit/accept drivers, and have automated scoring. Any member-organized sessions are free from the license level restrictions. In addition to taking part in the different public sessions, a member can use a test mode to drive alone on any track with any car, assuming he has purchased the license to use the content.[10]


The company behind, FIRST, LLC., was established in Bedford, Massachusetts in September 2004 by David Kaemmer and John W. Henry after the demise of Papyrus Design Group, which Kaemmer had also co-founded.[11][better source needed] The iRacing service has been in development since then, using code from Papyrus' NASCAR Racing 2003 Season as a starting point. According to Kaemmer, iRacing retains the multi-body physics system of NASCAR Racing 2003 Season, as well as some of the track presentation and multi-user packet code, but everything else has been changed, or is completely new like the tire model and graphics engine.[12] The service receives regular updates between 12-week competition seasons.[13]

In May 2009, NASCAR and announced a five-year deal of an online NASCAR-sanctioned racing series and on February 13, 2015, announced a six-year extension of their agreement.[14][better source needed] also provides the software used in the NASCAR Hall of Fame simulators.[15]

Laser scanning

iRacing copies real-world tracks using LIDAR. This technology makes the track's geometry more accurate.[1][16]

Virtual reality

iRacing has full support for both the Oculus Rift CV1 and HTC Vive.[17][better source needed]


While the licenses to 16 cars and 22 tracks offering a total of 70 track configurations are provided in the subscription's base content,[18] users must purchase individual licenses for each additional vehicle and track that they wish to drive. The game offers 94 tracks.[19] This total includes two of the tracks on the service that have been rescanned and reproduced (Daytona and Phoenix), because of modifications made to the track since they had originally been produced for iRacing, One Tech Tracks (New Jersey Motorsports Park available for test driving and hosted sessions while in an incomplete state), as well as iRacing's one fictional track which is a skid pad called "Centripetal Circuit", meant for use in acquiring data about your vehicle's dynamics.

Staying true to their focus on remaining a motorsports simulation, the vehicles on are almost exclusively digital models of purpose built race cars as opposed to street legal sports cars or supercars and all of the content is produced using a combination of laser scan data, CAD data, live audio samples, and thousands of photographs to be as faithful a digital reproduction as possible within their means.[20][better source needed]

Since December 4, 2018, iRacing offers a day-night-cycle, offering more dynamic racing due to e.g. temperature impacts and limited sight at night.[21]

On October 18, 2016, a partnership with Ferrari was announced. The first car to be released will be the 2016 Ferrari 488 GTE.[22]

The developers have established numerous partnerships with real-world racing organizations and series, including NASCAR, IndyCar, Supercars Championship, the SCCA, the Skip Barber Racing School, the Volkswagen Jetta TDI Cup, the new Formula Renault 2.0, the Star Mazda Championship, the Blancpain Endurance Series and McLaren F1.[23][better source needed] Categories of vehicles available include open wheel cars such as Formula 1 cars like the McLaren-Honda MP4-30, many American stock cars such as those used in NASCAR series, Australian V8 Supercars, several GT3 cars used in the Blancpain series such as the Audi R8 LMS GT3, trainers such as the Skip Barber or Legends Ford, sports cars such as Ford Mustang FR500 and prototypes such as the Corvette Daytona Prototype.[24][better source needed]

A variety of tracks of are available in the service to support competitions for the diverse selection of cars such as classic grand prix tracks like the Autódromo José Carlos Pace and Autodromo Nazionale di Monza, the whole complement of major NASCAR ovals such as Daytona International Speedway and a variety of short-track ovals such as Lanier and Indianapolis Raceway Park.[25][better source needed]

Dirt track racing

On April 1, 2016, the developers announced that they would introduce dirt track racing in the game.[26][better source needed][27] The patch was introduced on March 29, 2017, and included new vehicles such as Dirt Super Late Model, Dirt Sprint and Dirt Street racing cars. Moreover, the developers acquired licenses of Eldora Speedway, Volusia Speedway Park, and Williams Grove Speedway.[28] These three tracks, along with a revised, dirt version of USA International Speedway became the four dirt tracks on iRacing.[29][better source needed][30][31] Later, the dirt version of Lanier Raceplex and Knoxville Raceway became available.

Also in early 2017, iRacing announced partnerships with the United States Auto Club and World of Outlaws, two of the major North American dirt track racing sanctioning bodies.[32][33]

Note: The above list is compiled from the release history that goes back to 2008. So all tracks listed as Pre 2008 is not path of the release notes, but are mentioned in there, normally in conjunction with changes made to them. [Ref: Release Notes thread (Requires Logon)] Some of the releases has a release date, others are referring to the race season it was released. If the date is available is was used, otherwise the race season was used as a release date, but the chronology should be intact.

Subscription and operation

iRacing can only be played online on servers run by, and participation requires a subscription to the service. Additional cars and tracks are subject to additional one-time charges. As of May 2020, the subscription package includes a set of 18 race courses with 30 available configurations, a fictional skid pad (named Centripetal Circuit in the game), and over 18 cars with which to practice and race.[34][better source needed]

Reception was launched to the public on August 26, 2008.[38][better source needed] By July 2009 more than 16,000 individuals had subscribed to the service.[39] The company said there were 50,000 members as of December 2013.[40][better source needed] has received favorable reviews from automobile, racing and gaming magazines as well as websites dedicated to racing simulators.[41][42][43][44] The service has also been criticized for not yet including features often found on other racing simulators, such as rain and more advanced visual damage modeling.[45] PC Gamer stated that the game was "not one that will be to everyone's taste", while GameStar back in 2009 concluded "The graphics give the impression of an unfinished beta, but at least the atmosphere between the players is always friendly."[36][37]
