Barcelona: Perez leads after 1 hour

After an hour of driving on a wet track, it's the Mexican Sergio Perez who leads the debates thanks to a time of 1:26:789. The Sauber driver is ahead of the Red Bull Mark Webber's RB7, the Force India of Nico Hulkenberg and the T128 of Davide Valsecchi. The four men are the only ones to have been credited with a time for the moment. All the cars seem to be fitted with intermediate tires.

Note that the session has just been interrupted by the stop on the track of the Toro Rosso STR6 Sébastien Buemi.
