Young German driver Sebastian Vettel of team Red Bull set the fastest time of the second free practice session of Friday at the Grand Prix of Singapore.

His teammate Mark Webber was first when he spun at Turn 23 and damaged his Red Bull against the concrete wall, which brought up the red flag.

Fernando Alonso, fastest of all in Sector 1 (with Lewis Hamilton) drove his Renault R29 to second place.

Heikki Kovalainen was a surprise third in his McLaren-Mercedes, beating Nick Heidfeld (BMW-Sauber) and Jenson Button (Brawn-Mercedes) who suddenly slowed down in Sector 3 after having set his personal best in Sectors 1 and 2.

Kovalainen’s teammate, reigning World Champion Lewis Hamiton ranked 9th, one place ahead of Button’s teammate Rubens Barrichello. Hamilton was as fast as Alonso in Sector 1 but lost a great deal of time in Sector 3 compared to Vettel.

The two F1 rookies, Romain Grosjean (Renault) and Jaime Alguersuari (Toro Rosso) were slowest of the group, respectively 2.3 and 2.7 seconds down Vettel on this difficult street circuit.
