Group GT3 is a set of regulations maintained by the Fédération Internationale de l’Automobile (FIA) for grand tourer racing cars designed for use in various auto racing series
throughout the world. Since it’s inception in 2005, Group GT3 has expanded to become the de facto category for many national and international grand touring series, although some series modify the ruleset from the FIA standard.

GT3 allows for a wide variety of car types to be homologated with almost no limit on engine sizes and configurations or chassis construction or layout. GT3 cars must be based on production road car models in mass production. Performance of all the Group GT3 cars are regulated, either by the GT Bureau of the FIA or by a series’ specific ruling body, through a Balance of Performance that adjusts limits on horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from becoming dominant in the class. Over 20 automobile manufacturers have built or been represented with GT3 machines, including such iconic brands as Ferrari, Porsche and Mercedes. (source: wikipedia.com)
