Practice 1 Report - Raikkonen tops the timesheets

Kimi Raikkonen was fastest in the first session of the Belgian Grand Prix, half a second up on the two McLarens of Lewis Hamilton and Fernando Alonso. Nick Heidfeld was fourth fastest in his BMW, just a tenth slower than Alonso. Felipe Massa went off at Rivage early in the session and thus lost the entire 90-minute session.

Nico Rosberg was fifth quickest, just three-tenths behind Heidfeld but ahead of the second BMW Sauber of Robert Kubica. Alexander Wurz was seventh but was six-tenths off Rosberg's pace. The top 10 was completed by Jarno Trulli's Toyota, Heikki Kovalainen in the Renault and Jenson Button's Honda.

Outside the top 10 were Giancarlo Fisichella (Renault), Ralf Schumacher (Toyota), the two Red Bulls (Mark Webber and David Coulthard) and Rubens Barrichello in his Honda.

Sebastian Vettel was next in his Toro Rosso but team-mate Tonio Liuzzi was unable to set a decent time because his cars stopped beside the track and he was 20th. Behind Vettel were the two Super Aguri Hondas of Takuma Sato and Anthony Davidson and the Spykers of Adrian Sutil and Sakon Yamamoto, who were 19th and 21st.

Massa was last.
