* Lap 1: On pole position for the first time this season – but the 64th in his career, just one short of Ayrton Senna’s all-time record – Michael Schumacher makes a clean start to beat fellow front-row Juan Pablo Montoya into the first corner. Kimi Räikkönen is up from fourth to third – despite starting, like Montoya, from the dirtier side of the track. The Finn then makes short work of Montoya to take second. Behind, Alonso all but runs into Ralf Schumacher and is forced over the kerbs, Rubens Barrichello crunches into Jarno Trulli and Christian Klien rolls – without injury – after riding over one of Jacques Villeneuve’s wheels. Later in the lap, Alonso’s front wing flies off. David Coulthard hits it, loses his right-front wheel and spins into retirement at Turn 12. Alonso and Barrichello pit for repairs at the end of the lap, which Trulli completes in fourth place ahead of Ralf Schumacher, Jenson Button, Takuma Sato, Nick Heidfeld, Giancarlo Fisichella, Felipe Massa, Jacques Villeneuve, Mark Webber, Narain Karthikeyan, Christijan Albers, Robert Doornbos and Tiago Monteiro, who also makes a quick pit stop.
