Williams driver Nico Rosberg clocked the fastest lap of the final British Grand Prix practice session ahead of qualifying at 1300 BST.
Team-mate Kazuki Nakajima was just behind him as nine drivers finished below the one minute 20 seconds mark at a cold and cloudy Silverstone.
Sebastian Vettel, who topped both sessions on Friday, again looked impressive in his updated Red Bull.

Ferrari seems to have already made an improvement from its difficult Friday, Felipe Massa and Kimi Raikkonen slotting into fifth and sixth respectively.
Unlike Friday’s two practice sessions, the tricky track conditions awaiting drivers for final practice meant few were keen to venture out of their garages for fast laps until the surface had dried out some more.

Renault’s Nelson Piquet Jr eventually set the ball rolling after 23 minutes, although his opening time of 1m28.756s was some nine seconds slower than Friday’s fully dry benchmark. ITV
