It was a big day for Williams as they launched their FW35, the last team to uncover their 2013 challenger, and it appears the wait was worthwhile as the new car seemed pretty handy straight out the box with Pastor Maldonado on driving duty, he did 86 trouble free laps – albeit a second down on the best time of the day – around the circuit where last year he scored his maiden grand prix victory. Next best was Daniel Ricciardo in the Toro Rosso STR8 with 73 laps to his credit. Further down the order than expected was Sergio Perez, who admitted after Jerez that he was still getting used to the layout of the McLaren which was different in just about every respect to the Sauber he raced last year. He was seventh fastest, 1.5 seconds off Rosberg’s best. Paul di Resta was eighth fastest in the Force India VJM06 with 82 laps and 0.020 down on Perez ahead of him, while 2.5 seconds adrift of the pace setters was Esteban Gutierrez in the Sauber C32. Over four seconds off the pace were Marussia and Caterham. with Max Chilton tenth and Charles Pic slowest. The pair were also responsible for the only two red flag stoppages on the day.
