About iRacing

iRacing.com is an online, subscription-based racing simulation service for Microsoft Windows created by iRacing.com Motorsport Simulations. In addition to accurately modeled vehicles and tracks, iRacing provides servers on which to race and practice and a sanctioning body to organize and oversee competition within the service.

From the start, iRacing has been marketed as both an entertainment service and a training tool for real life racers.[2] They have established numerous partnerships with real-world racing organizations and series, including NASCAR, GRAND-AM, IndyCar, the SCCA, the Skip Barber Racing School, the Volkswagen Jetta TDI Cup, the Star Mazda Championship and Williams F1 among others.[3][4]

The service was launched to the public on August 26, 2008. As of December 2010, 40,000 individual member accounts had been created. 

Gameplay

The iRacing company aims to cater both to real-world racers and racing simulation enthusiasts by offering a realistic simulation of motorsport with accurate track, vehicle and physics modeling, and with all of the cars and tracks officially licensed. iRacing can only be driven online on servers run by iRacing.com, and participation requires a subscription to the service. The subscription package includes a basic set of 10 tracks and six cars with which to practice and race. Additional cars and tracks are subject to additional one-time charges. Vehicles in iRacing are divided into classes which correspond to the identically named driver license classes, except for the two different Rookie car classes which can both be driven with the same Rookie driver license. iRacing creates each track using proprietary Exactrac laser mapping technology to replicate the tracks with millimeter precision.
