* Lap 1: At the start of the race Fernando Alonso maintains his advantage over Michael Schumacher and Felipe Massa with Jenson Button taking fourth and Kimi Raikkonen fifth. Jarno Trulli grabs sixth while Rubens Barrichello drops back from fourth to seventh. Next up is Jacques Villeneuve with a very fast-starting Nick Heidfeld, up from 13th to ninth. There is a mess in the midfield as Ralf Schumacher tags Tonio Liuzzi and the Italian spins across the road into David Coulthard's Red Bull. In the sort-out which follows Mark Webber goes from 19th on the grid to 12th and Takuma Sato is up from 20th to 14th.
