Classification -- Qualifying

The 2004 United States Grand Prix, officially the XXXIII Foster's United States Grand Prix, was a Formula One motor race held on June 20, 2004 at the Indianapolis Motor Speedway in Indianapolis, Indiana. It was the ninth round of the 2004 Formula One season. Rubens Barrichello started from pole position in his Ferrari ahead of teammate Michael Schumacher. However, following a start-line incident between five cars, four of whom retired as a result, Schumacher overtook Barrichello on the safety car restart on lap six, and despite a threat from Barrichello after the final pit stops, Schumacher held on to take his eighth win of the season. Takuma Sato became only the second Japanese driver to achieve a podium finish. The race saw two serious accidents caused by Michelin tyre failures in what would be a precedent for the 2005 United States Grand Prix, at which all Michelin-shod cars withdrew over safety concerns. First, Fernando Alonso's Renault speared off the track at the end of the pit straight on lap nine. Later, Ralf Schumacher's Williams suffered the same fate, but in the most dangerous part of the track, causing him to hit the wall at a ninety-degree angle rearwards. The impact left Schumacher with spinal fractures and concussion, which prevented him from racing until the 2004 Chinese Grand Prix, three months later.
