The 1956 Florida International Grand Prix of Endurance powered by Amoco took place on 24 March, on the Sebring International Raceway, (Florida, United States). It was the second round of the F.I.A. World Sports Car Championship. For the sixth running of the event, was a sign to many in the automotive community that this race had become North America's premier sports car race, and from an international standpoint second only to the 24 Hours of Le Mans.
However, this race came just eight months after the disaster at Le Mans. The United States was not immune to the fallout following that race, and the American Automobile Association decide to withdraw from all participation in motor sport. This left the promoters with no international recognition for the race, and therefore no FIA approval. It was very simple; no FIA approval, no international race.[1]
Alec Ullmann, one of those promoters, and founder of Sebring, approached the Sports Car Club of America, but could not maintain its amateur status, if it supported the race. Ullmann did however obtain "special permission" from the FIA to allow him organise the event himself, through his Automobile Racing Club of Florida, and issued the international licenses.[2]
