Rosberg and Vettel will start tomorrow from the front row of the grid in a mad classification marked by intermittent rain that allowed the Marussia to pass into Q2 in good positions. The other side of the coin is Hamilton, sixth, and Williams and Ferrari who with strategy errors could not get into Q2. 

A qualifying many will not forget, this afternoon at Silverstone. Marked by intermittent rain, and dancing tyres, teams were unable to predict right the track situations and unusual things occurred in each of the three qualifying sessions. Great performance of Marussia and Jules Bianchi as the front teams committed serious strategic mistakes.
The Q1 has been the most incredible of the season. The rain just loosened but the track still was damp, the air too. The Marussia and Sauber were the first out on track shoeing intermediate tyres. The other drivers have continued doing so until five minutes left to the cars behind have dared to use soft and this has caused situations like Q1 led by Gutiérrez, Chilton or Bianchi.
Immediately the other teams have copied them to avoid running out, times have been lowered about six seconds and Bianchi and Chilton have finished in fourth and sixth positions respectively. The other side of the coin and hitting the monumental theater has been the wrong decisions in Ferrari and Williams. Waiting for the final lap, they found out the rain returne.This means: They were out of Q2. Positions 17 to 22: Bottas, Massa, Alonso, Raikkonen, Ericsson and Kobayashi.
The Q2, led by Mercedes, Marussia has left at 12 and 13 positions, behind Grosjean. Great performance from modest team and its drivers, especially Bianchi, who set a time one second faster than his team-mate Max Chilton. Behind the British will start Gutiérrez, Maldonado and Sutil.
The Toro Rosso were the first to leave the pit lane at the start of Q3, using medium tyres. Kvyat was the one who discovered that rain turned to make appearance at Silverstone. Yet no one fitted to the intermediate tyres though times were five seconds above the Q2. With five minutes on track activity they kept waiting for the conditions to change. Vettel was the only driver without having scored any time.
Less than two minutes remaining. The drivers came out with mediums and scored times which would enable them to fight for a good position. Sponsored by Red Bull, its cars were in boxes except for Sebastian Vettel.
The time seemed to be excellent but it was not. The classification was upside down and Rosberg achieved the pole followed by Vettel and Button. Hülkenberg and Magnussen would be the two drivers ahead of Lewis Hamilton sixth and Perez seventh, while Ricciardo and Toro Rosso should conform with the closing the rankings after a mistake.
Note that the two Caterham, and at the hands of Cristijan Albers after Tony Fernandes sells the team have not reached 107% of the fastest time set in Q1 by Nico Rosberg, and unless the FIA annulled the rule, asserting to changing weather conditions, green cars may not participate in the race tomorrow. Regarding penalties must also remember that Gutierrez will have ten more positions on the grid for the incident at the stop in, Chilton five  due to the gearbox and Maldonado is under investigation for an incident during Q2.
Tomorrow at two p.m. we will see how evolves the Grand Prix of Great Britain and how the weather behaves.
