Nico Rosberg took the honours for Mercedes on the opening day of action for Sunday's 2013 F1 British Grand Prix.
After the first session this morning was a virtual wash-out, all the runners made the most of dry conditions, with Rosberg moving to the top 50 minutes in, his best lap a 1 minute 32.248 seconds. In the end that left him almost three tenths up on the Red Bull of Mark Webber, while Sebastian Vettel was third in the sister RB9, 0.133 seconds slower.
Britain's Paul di Resta led the way for the home contingent in fourth in his Force India, just ahead of fellow countryman and Mercedes driver Lewis Hamilton, the last of the runners in the 1m 32s bracket.
Behind, Daniel Ricciardo and Jean-Eric Vergne took sixth and seventh for Toro Rosso, with Force India's Adrian Sutil, Lotus' Romain Grosjean and Ferrari team leader, Fernando Alonso rounding out the top ten. Alonso's best – a 1m 33.494s – was more than a second off the pace.
Jenson Button was eleventh for McLaren, despite the Woking-based team taking a number of updates to Silverstone, two spots ahead of team-mate, Sergio Perez in P14, while Nico Hulkenberg and Kimi Raikkonen were sandwiched between in twelfth and thirteenth.
Esteban Gutierrez was next up with the Williams of Valtteri Bottas and Pastor Maldonado in 16th and 17th.
Jules Bianchi led the 'third' division for Marussia, two tenths up on Caterham's Giedo van der Garde. Charles Pic and Max Chilton trailed, with Ferrari #2 Felipe Massa slowest and only doing 7 laps after he went off and into the barriers at Stowe, 20 or so minutes into the session. Unsurprisingly he did the least amount of laps, while at the other end of the spectrum, Vergne and Grosjean did the most, 38 each.
