The Fédération Internationale de l'Automobile (FIA, English: International Automobile Federation) is an association established as the International Association of Recognized Automobile Clubs to represent the interests of motoring organisations and motor car users. The FIA is mostly known as the governing body for many auto racing events. The FIA also promotes road safety around the world.



SCCA Pro Racing, located just outside of the Racing Capital of the World in Brownsburg, IN, is a wholly owned subsidiary of Sports Car Club of America, Inc. – a 65,000-member organization dedicated to motorsports events and voting member of the Automobile Competition Committee of the United States (ACCUS) – the FIA delegate for the United States. Since our first event in 1963, SCCA Pro Racing has been at the forefront of the professional racing landscape in the United States, and we continue to provide full-service organization, operational support, and sanctioning for numerous professional racing series. Known for its operational expertise, SCCA Pro Racing has been the choice of privately owned racing series, as well as those promoted by automobile manufacturers, to conduct all facets of their Championships. Current series include the F4 U.S. & Formula Regional Americas Championships, The Trans Am® Series Presented by Pirelli, FIA Formula E, Formula Race Promotions, Radical Cup North America, and Creventic 24H.



Parella Motorsports Holdings: PMH is a burgeoning motorsport holding company. Its premier properties are the wholly-owned Sportscar Vintage Racing Association (SVRA) and majority ownership of the Trans Am Racing Company (TARC). PMH took full commercial rights of F4 U.S. and FR Americas in 2021. Together and in concert with independent properties such as IGT, the two organizations combine to produce America’s largest and most diverse motorsport festivals.
