Qualifying
All the running on Saturday was cancelled due to Typhoon Ma-on, meaning that both the qualifying sessions were run on Sunday morning. Qualifying took place on a track that was still damp but is drying out; Michael Schumacher took advantage of this and, taking to the track among the last thanks to an excellent performance in the first session, won pole position, with a large advantage over his rivals. Second was Ralf Schumacher, while Webber surprisingly took third place, still a full second behind the pole position time. The two BARs of Sato and Button followed, preceding Trulli, Fisichella, Coulthard and Villeneuve. The difficult conditions of the track put several drivers in difficulty: Alonso, Räikkönen, Montoya and Barrichello made mistakes, relegated to the second half of the grid.
Race
After some testing plagued by bad weather, the race started in dry conditions and sunshine. At the start, Michael and Ralf Schumacher had no difficulty maintaining the lead. Webber on the other hand, started poorly and was overtaken by Button, Sato and Trulli. Michael Schumacher immediately gained a clear advantage over his opponents. The only one who drove a similar pace was his brother Ralf, who also went into the pits first on the 9th lap. When Michael Schumacher refueled four laps later, he rejoined the track as the leader, ahead of Button (who started with a two-stop strategy and therefore had not yet pitted). The race for first place was practically over. While the BAR duo fought for third place (Sato with a three-stop strategy against Button's), the race is livened up by the comeback of Barrichello, Montoya, Räikkönen and Alonso; Trulli, however, is relegated and, having started with little petrol on board, has to deal with a Toyota that is very difficult to manage with a full tank of fuel.
On lap 20, Webber retired for a rather unusual reason: the cockpit of his Jaguar inexplicably overheated to such an extent that the Australian driver suffered minor burns on his thigh. After the first series of stops, Trulli, Montoya, Barrichello and Fisichella gave rise to an intense duel, with the Sauber driver having difficulty with the tyres, having to give way to the Brazilian from Ferrari, but managing to defend himself from the other two until his second refueling, on the 24th lap. Michael Schumacher continued to lead undisturbed and didn't relinquish the lead for one lap. His brother Ralf also had no particular difficulties defending his second place from the two BAR drivers. Coulthard climbs sharply up the overall standings and initially only makes two stops. With around twenty laps to go, the Scot was in fifth place, having refueled for the second time.
Behind him, however, Barrichello quickly recovered. On lap 38, the Brazilian attempted an attack, but the McLaren driver came out of the corner and the two subsequently touched each other. The two cars were damaged beyond repair and both had to give up. Alonso moved up to fifth place. Meanwhile, Button prevailed against his teammate in the duel for the podium. Sato got off to a slow start and pain from an old shoulder injury returned during the race and had to go without liquid for much of the race when a water bottle stopped working. [4] BAR virtually secured second place in the Constructors' Championship. The team increased its advantage over Renault to 16 points with one race remaining.
There were no more surprises in the final laps and Michael Schumacher won ahead of Ralf Schumacher, Button, Sato, Alonso, Räikkönen, Montoya and Fisichella. It was Ferrari's fifteenth victory of the season. In doing so, they equaled the previous record of the McLaren, which won fifteen out of sixteen Grands Prix victories in 1988, and the Ferrari, which won fifteen out of seventeen in 2002.
It was the last time the Schumacher brothers finished in 1–2 formation (having done so on four other occasions: 2001 Canadian Grand Prix, 2001 French Grand Prix, 2002 Brazilian Grand Prix, 2003 Canadian Grand Prix). It was also the last 1-2 finish between German drivers until the 2013 Indian Grand Prix.
