* Lap 1: Starting from pole for the fifth consecutive grand prix, world championship leader Fernando Alonso makes a clean getaway, but team-mate and fellow front-row starter Giancarlo Fisichella moves slightly early, then falters before being beaten away by Kimi Räikkönen. Jarno Trulli grabs fourth, but Michael Schumacher is beaten away from fifth by Nico Rosberg – and Juan Pablo Montoya soon muscles the German down to seventh. Jenson Button lies eighth from Jacques Villeneuve, Felipe Massa, Nick Heidfeld, Mark Webber, Vitantonio Liuzzi, the slow-starting Rubens Barrichello, Christian Klien, Scott Speed, Ralf Schumacher, Takuma Sato, David Coulthard (who qualified 16th but started last, in the wake of an unscheduled pre-race engine change) and Franck Montagny. MF1 team-mates Tiago Monteiro and Christijan Albers collide at Turn 10. The Portuguese driver pits for repairs; Albers retires on the spot.
