From the start, iRacing has been marketed as both an entertainment service and a training tool for real life racers. They have established numerous partnerships with real-world racing organizations and series, including NASCAR, IndyCar, V8 Supercars, the SCCA, the Skip Barber Racing School, the Volkswagen Jetta TDI Cup, the Star Mazda Championship, the Blancpain Endurance Series and Williams F1 among others.
The iRacing World Championship Grand Prix series (iWCGPS) is an online racing series hosted by iRacing.com. It features the top 50 sim-racers from iRacing’s road course series competing for more than $35,000 in cash and prizes.
iWCGPS drivers race digital versions of the Williams-Toyota FW31 on laser-scanned versions of many of the world’s legendary road courses including Spa-Francorchamps, Suzuka and Silverstone.
The service was launched to the public on August 26, 2008. There were over 50,000 active members as of December 2013, and over 55,000 by late May 2015.
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 seven 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.
