Race
At the start, Alonso and Jarno Trulli were able to maintain their respective positions on the starting grid, followed by Fisichella and Mark Webber. Further back, Nick Heidfeld overtook the two Red Bulls and was now behind Kimi Räikkönen.
At the start of the second lap, Jenson Button attacked Räikkönen on the start-finish straight and overtook him, but retired immediately afterwards due to engine failure. At the same time, Patrick Friesacher in the Minardi went off the track in the first corner and also retired. A similar fate befell the other Honda engine, Davidson's, which caused a small fire.
During the 23rd lap, Räikkönen, who was in sixth place at the time, suffered a puncture and had to give up all desire to win. Three laps later, Jacques Villeneuve went off the track in the first corner and was the fourth driver to retire. Six laps later, Ralf Schumacher and Webber collided on the main straight, but without causing too much damage to the cars. Nineteen laps from the end, in the final corner, Webber tried to overtake Fisichella on the outside for third place, but the two collided: the Italian ended up on top of the Australian and both had to retire. Heidfeld benefited from this and took third place.
The Alonso ultimately won the race ahead of the Trulli and Heidfeld. For Alonso it was the second victory and the first since the 2003 Hungarian Grand Prix. Alonso's win made him the first Spaniard ever to lead the Formula 1 World Championship. It was Heidfeld's second podium finish and first since the 2001 Brazilian Grand Prix.
The race also marked Toyota's first-ever podium in Formula One and first Asian-licensed constructor to score a podium since 1968 United States Grand Prix when John Surtees drove for Honda in the 3rd place.
This was the first race since the 2003 Hungarian Grand Prix where neither Ferrari driver finished on the podium.
