Kimi Raikkonen rose to the top of the timesheets at Sakhir on Friday afternoon, as he set the fastest time of the day for Lotus in 1m 34.154s to beat Mark Webber's Red Bull by 0.030s.

Webber, who lapped in 1m 34.184s, was followed by his team mate Sebastian Vettel on 1m 34.282s, and the Ferraris of Fernando Alonso and Felipe Massa which sandwiched Paul di Resta's Force India. Alonso posted 1m 34.310s, Di Resta 1m 34.543s and Massa 1m 34.552s.

In a session that was cloudier and cooler than this morning's Practice One - the track temperature varied between 39 and 41 degrees Celsius and the ambient between 32 and 33 degrees - Romain Grosjean took seventh with 1m 34.631s in the other Lotus ahead of Nico Rosberg's Mercedes on 1m 34.666s, Adrian Sutil's Force India on 1m 34.932s and Lewis Hamilton's Mercedes on 1m 34.976s.

Once again there were few incidents. Hamilton ran wide in Turn One early on, and Sauber's Esteban Gutierrez and Caterham's Charles Pic had a minor altercation in the final corner when each had to make room for the other.

Jenson Button was 11th for McLaren on 1m 35.356s from Toro Rosso's Jean-Eric Vergne on 1m 35.506s, team mate Sergio Perez on 1m 35.589s and Daniel Ricciardo in the other STR8 on 1m 35.761s.

Sauber continued to struggle, with Nico Hulkenberg 15th on 1m 36.133s from Pastor Maldonado on 1m 36.279s ahead of his Williams team mate Valtteri Bottas on 1m 36.579s and Gutierrez on 1m 36.616s.

Pic showed the progress Caterham are making with the revised CT03 on his way to 1m 37.061s for 19th, as Max Chilton just edged out Marussia team mate Jules Bianchi, with 1m 37.313s to 1m 37.363s. Giedo van der Garde brought up the rear in his standard CT03, driven this morning by Heikki Kovalainen, on 1m 37.970s.
