The 2005 United States Grand Prix was a Formula One motor race held on June 19, 2005, at the Indianapolis Motor Speedway and was the ninth race of the 2005 Formula One World Championship. The event is one of the most controversial motor races, in Formula One or otherwise, in modern history. Out of the 20 cars that entered the race, only the six cars from the teams using Bridgestone tyres (Ferrari, Jordan and Minardi) competed. The remaining fourteen entrants, all using Michelin tyres, completed the parade lap, but retired to the pit lane before the race started.
