iRacing.com is a subscription-based simulation service for real-world racers and racing enthusiasts, as well as a platform for a new branch of global motorsport - known as internet racing - which is the sport of realtime, online racing. Controlled by the simulation's physics engine � a complex system of mathematical functions that replicates dynamic forces using data-driven calculations of action and reaction � the virtual race car is not just a graphical representation of a stock car, formula car or sports car, but a complex set of interrelated mechanical systems. To the driver it feels real because, mathematically, it is real. On the vehicle side, iRacing's engineers work closely with major auto manufacturers and racecar constructors to gather all the data necessary to construct a virtual vehicle that's faithful to the original not just in appearance but in its performance.
