Nico Rosberg managed back-to-back P1s at Silverstone on Friday as he was again quickest in FP2, a session that was red flagged twice.
On a hot afternoon, Lewis Hamilton and Rosberg seized control of the timesheets at the start of FP2 as all the drivers put in laps on the hard Pirelli tyres. Hamilton led the way with a 1:34.877 while Rosberg was 0.352s down as the drivers struggled to match their morning pace.
The running was briefly red flagged when, 17 minutes into the 90-minute session, Romain Grosjean beached his Lotus in the gravel on the outside of Luffield. "Something went wrong at the rear," was Grosjean's cry before he added "completely inconsistent, completely inconsistent."
Six minutes later the action was again underway only for Fernando Alonso to land up in the same gravel trap. The McLaren driver, though, was able to keep some speed and find more solid ground which helped him work his way out.
Just before the halfway point of the session, Rosberg and Sebastian Vettel were the first of the front runners to swap to the medium Pirelli rubber.
Rosberg went quickest with a 1:34.155 while Vettel slotted into second place. As for Hamilton, the reigning World Champion was able to find the pace in the first two sectors and finished up P3.
That became P4 as Kimi Raikkonen, the last of the front runners to swap to the medium tyres, jumped up to second place, 0.347s down – and he did so on his second flying lap.
Swapping to longer runs for the final 30 minutes, Rosberg held onto the P1 ahead of Raikkonen while Vettel was third. Hamilton retained fourth ahead of Daniil Kvyat and Daniel Ricciardo.
Rosberg also had the edge over his team-mate in the long runs with the German in the 38s while Hamilton was in the 39s. The Brit reported: "I can't get any faster than I am now."
The session was again red flagged with 15 minutes to go as Roberto Merhi was stuck at Luffield, half on the gravel, half on the track. However, as soon as the flag was thrown, the Manor driver was able to get his car going and returned to the pits with the rest of the field.
As soon as everyone was back in, the session was green-lighted and the drivers were allowed back on track for the final 13 minutes where long runs were again on order.
